Description

Technical Field

[0001] This invention relates to the field of data processing technology, and in particular to a method and system for energy efficiency assessment and optimization of the At-211 separation process. Background Technology

[0002] In existing technologies, the separation of the radioactive isotope At-211 typically employs a separation process based on an adsorption-elution mechanism, which falls within the scope of adsorption separation as described in B01D15 / 00. Specifically, existing methods often involve introducing an At-211-containing reaction solution into a separation column packed with a specific adsorbent material (such as activated carbon, resin, or inorganic adsorbent). The selective adsorption of At-211 on this material under specific acidity or solvent conditions achieves the separation of the target nuclide from associated impurity nuclides. Subsequently, the elution conditions are altered to desorb and collect the At-211.

[0003] However, in practical scenarios for preparing At-211 for nuclear medicine, the above separation methods have shortcomings in terms of energy efficiency assessment and control. For example, in continuously operating radionuclide production lines, to ensure separation purity, existing technologies often compensate for fluctuations in adsorption efficiency by extending the adsorption equilibrium time or performing multiple elution cycles. This directly leads to the separation column needing to maintain constant temperature and flow control for an extended period. Since the half-life of At-211 is only about 7.2 hours, the above operations not only increase the pumping and temperature control energy consumption per unit time, but may also cause a loss of effective nuclide activity during the elution stage, thereby affecting the usable activity output of the final formulation. Summary of the Invention

[0004] The purpose of this invention is to provide a method and system for energy efficiency evaluation and optimization of the At-211 separation process, aiming to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is as follows:

[0006] Firstly, a method for energy efficiency assessment and optimization of the At-211 separation process, the method comprising:

[0007] During the At-211 separation process, At-211 elution activity data and corresponding separation runtime are collected at preset time intervals to form raw operation data;

[0008] Based on the original operating data, the At-211 separation process is divided into time periods according to a preset time interval, and the change in At-211 elution activity within each separation time period is correlated with the corresponding separation runtime to generate separation contribution data.

[0009] Based on the separation contribution data, the separation contribution of multiple adjacent separation time periods is compared and processed to determine its trend characteristics over time. Based on the trend characteristics, a stage judgment result is generated to indicate whether the separation process has entered a low separation contribution interval.

[0010] Based on the stage judgment results, when the separation process is determined to enter the low separation contribution range, the operating resource input required to continue to perform the current adsorption or elution operation is quantified by combining the current At-211 remaining activity data, and a cost assessment result of the operating cost per unit effective activity is generated.

[0011] The cost assessment result is compared with the preset cost threshold. When the cost assessment result exceeds the preset cost threshold, a separation process structure adjustment instruction is generated, and the corresponding separation process structure adjustment operation is executed according to the instruction. The separation process structure adjustment operation includes at least one of the following: prematurely terminating the current adsorption or elution step, skipping the subsequent separation time period, or switching to the next separation condition.

[0012] After completing the structural adjustment operation of the separation process, the acquisition of At-211 elution activity data and the generation of separation contribution are re-executed, so that the subsequent At-211 separation process can continue to carry out energy efficiency assessment and structural optimization under the updated separation structure.

[0013] Preferably, based on the original operating data, the At-211 separation process is divided into time periods according to a preset time interval, and the change in At-211 elution activity within each separation time period is correlated with the corresponding separation runtime to generate separation contribution data, including:

[0014] Based on the original operating data, the At-211 separation process is divided into continuous time periods according to a preset time interval. The starting elution activity data, ending elution activity data, and separation runtime data corresponding to each separation time period are obtained to generate basic data for the time period.

[0015] Based on the basic data of the time period, the difference between the starting elution activity data and the ending elution activity data in each separation time period is processed to generate the elution activity change data for the corresponding separation time period.

[0016] Based on the elution activity change data, the elution activity change data is time-normalized to generate standardized activity change data that eliminates the influence of differences in separation runtime.

[0017] The standardized activity change data and the separation runtime data of the corresponding separation time period are jointly processed to generate initial separation contribution data that characterizes the unit operation contribution level of each separation time period.

[0018] Based on the initial separation contribution data, the initial separation contributions for multiple consecutive separation time periods are cumulatively corrected to generate separation contribution data for subsequent trend analysis.

[0019] Preferably, based on the separation contribution data, the separation contribution of multiple adjacent separation time periods is compared to determine its trend characteristics over time, and a stage determination result is generated based on the trend characteristics to indicate whether the separation process has entered a low separation contribution interval, including:

[0020] Based on the separation contribution data, the separation contribution data corresponding to multiple consecutive separation time periods are selected in chronological order to generate contribution sequence data for trend analysis.

[0021] Based on the contribution sequence data, sequential difference processing is performed on the separation contribution data corresponding to adjacent separation time periods to generate change direction data that characterizes the direction of change of separation contribution.

[0022] Based on the change direction data, determine whether the change direction of the separation contribution maintains a consistent structure within a preset number of consecutive separation time periods, and generate trend feature data of the continuous change of the separation contribution over time when it remains consistent.

[0023] Based on the trend feature data, the corresponding separation contribution value range is processed for range determination. When the separation contribution value corresponding to the trend feature data is continuously in the preset low separation contribution range, a stage determination result is generated to indicate that the separation process has entered the low separation contribution range.

[0024] Preferably, based on the stage determination result, when the separation process is determined to have entered a low separation contribution range, the operational resource input required to continue performing the current adsorption or elution operation is quantified by combining the current At-211 residual activity data, generating a cost assessment result for the operational cost per unit of effective activity, including:

[0025] Based on the stage judgment results, when the separation process enters the low separation contribution interval, the At-211 residual activity data at the corresponding time node is obtained to generate the current residual activity data;

[0026] Based on the current remaining activity data and the corresponding time points, the decay estimation process is performed on the changes in At-211 activity during the subsequent separation period to generate usable activity assessment data for the subsequent separation stage.

[0027] Based on the current operating status of the separation unit, determine the separation runtime and corresponding operating resource input required to continue the current adsorption or elution operation in subsequent separation stages, and generate operating resource requirement data;

[0028] By jointly processing operational resource demand data and available activity assessment data, a cost assessment result is generated that characterizes the operational cost required per unit of effective activity in the subsequent separation stage.

[0029] Preferably, the standardized activity change data and the separation runtime data for the corresponding separation time period are jointly processed to generate initial separation contribution data characterizing the unit operational contribution level for each separation time period, including:

[0030] Based on the separated runtime data, the runtime is grouped into at least two runtime categories, and a corresponding contribution processing rule is established for each runtime category.

[0031] Within each runtime category, the standardized activity change data for the corresponding separated time period are subjected to interval mapping processing to generate intermediate contribution data that reflects the activity output characteristics under that runtime category.

[0032] Based on the intermediate contribution data, cross-category calibration is performed on the contribution results between different runtime categories to generate calibrated intermediate contribution data.

[0033] Based on the intermediate contribution data after calibration, initial separation contribution data characterizing the unit operational contribution level for each separation time period is generated.

[0034] Preferably, based on the change direction data, it is determined whether the change direction of the separation contribution maintains a consistent structure within a preset number of consecutive separation time periods, and if it remains consistent, trend feature data of the continuous change of the separation contribution over time is generated, including:

[0035] Based on the data on the direction of change, construct a sequence of the direction of change in chronological order;

[0036] Based on the sequence of change directions, the consistency of the change directions of adjacent separation time periods is determined segment by segment, and local consistency results between each separation time period are generated.

[0037] Based on the local consistency results, the consistency status within multiple consecutive separation time periods is cumulatively determined to generate an overall consistency assessment result.

[0038] When the overall consistency assessment results meet the preset continuous consistency conditions, it is determined that the direction of change of the separation contribution remains consistent within the continuous separation time period;

[0039] After ensuring that the direction of change in the separation contribution remains consistent, trend feature data characterizing the continuous change of the separation contribution over time is generated.

[0040] Preferably, based on the current remaining activity data and corresponding time points, the decay estimation process is performed on the changes in At-211 activity during the subsequent separation period to generate usable activity assessment data for the subsequent separation stage, including:

[0041] Based on the time nodes corresponding to the current remaining activity data, determine multiple consecutive separation time periods corresponding to the subsequent separation phase, and generate corresponding time span data for each separation time period;

[0042] The current remaining activity data is used as the initial activity data for the first separation time period;

[0043] For each separation time period, based on the corresponding initial activity data of the stage and the time span data of the separation time period, the activity decay ratio of At-211 in the separation time period is determined, and the initial activity data of the stage is updated accordingly to generate the stage remaining activity data corresponding to the separation time period.

[0044] The residual activity data generated in the previous separation period is used as the initial activity data in the next separation period, and the activity decay estimation process for multiple consecutive separation periods is completed in sequence.

[0045] Based on the remaining activity data corresponding to each separation time period, the activity change process in subsequent separation stages is summarized to generate available activity assessment data that reflects the overall available activity level in subsequent separation stages.

[0046] Secondly, the At-211 separation process energy efficiency assessment and optimization system, the system comprising:

[0047] The data acquisition module is used to collect At-211 elution activity data and corresponding separation runtime at preset time intervals during the At-211 separation process to form raw operation data;

[0048] The separation contribution generation module is used to divide the At-211 separation process into time periods according to preset time intervals based on the original operating data, and to correlate the change in At-211 elution activity with the corresponding separation runtime in each separation time period to generate separation contribution data.

[0049] The trend analysis and stage determination module is used to compare the separation contribution of multiple adjacent separation time periods based on the separation contribution data, determine the trend characteristics of its change over time, and generate a stage determination result based on the trend characteristics to indicate whether the separation process has entered a low separation contribution range.

[0050] The cost assessment module is used to quantify the operational resource input required to continue the current adsorption or elution operation based on the stage judgment results when the separation process enters the low separation contribution range, combined with the current At-211 remaining activity data, and generate a cost assessment result of the operational cost per unit effective activity.

[0051] The structural adjustment decision module is used to compare the cost assessment result with the preset cost threshold. When the cost assessment result exceeds the preset cost threshold, a separation process structural adjustment instruction is generated, and the corresponding separation process structural adjustment operation is executed according to the instruction. The separation process structural adjustment operation includes at least one of the following: prematurely terminating the current adsorption or elution step, skipping the subsequent separation time period, or switching to the next separation condition.

[0052] The structural adjustment execution module is used to trigger the data acquisition module and the separation contribution generation module to re-execute the acquisition of At-211 elution activity data and the generation of separation contribution after the structural adjustment operation of the separation process is completed, so that the subsequent At-211 separation process can continue to carry out energy efficiency assessment and structural optimization under the updated separation structure.

[0053] The above-described solution of the present invention has at least the following beneficial effects:

[0054] First, by collecting elution activity data and corresponding separation runtime during the At-211 adsorption and elution separation process, and dividing the separation process into time periods according to preset time intervals, the separation process can be decomposed into multiple operating intervals with clear time boundaries. This avoids the uncertainty caused by evaluating the separation effect based solely on the overall operating time or single elution results in the existing technology, and provides basic data support for the energy efficiency analysis of the separation process.

[0055] Secondly, by correlating the change in At-211 elution activity with the corresponding separation runtime in each time period, separation contribution data is generated. This allows for the quantification of the actual contribution of different operating stages to the At-211 separation results per unit operating time, thereby distinguishing between separation stages that contribute more to the target nuclide output and those that contribute less, and avoiding maintaining the established separation conditions even when the adsorption efficiency has significantly decreased.

[0056] Furthermore, by comparing the separation contribution of multiple adjacent separation time periods and combining the trend characteristics of the separation contribution over time to generate stage judgment results, it is possible to determine whether the separation process has entered a low separation contribution range by observing the changes over a continuous time period. This reduces misjudgments caused by short-term fluctuations or single-point data anomalies, thereby providing a more stable stage identification basis for the subsequent operation and control of the separation process.

[0057] Based on this, when the separation process is determined to have entered a low separation contribution range, the operational resource input required to continue the current adsorption or elution operation is quantified by combining the current At-211 remaining activity data, and an assessment result of the operating cost per unit of effective activity is generated. This allows subsequent operational decisions for the separation process to simultaneously consider the relationship between the remaining available activity level and the consumption of operational resources, thereby avoiding the continued execution of separation operations with limited contribution under the condition of a short At-211 half-life.

[0058] Finally, by comparing the operational cost assessment results with a preset cost threshold, and performing the corresponding separation process structure adjustment operation when the threshold is exceeded, the separation process can terminate the current adsorption or elution step, skip subsequent separation time periods, or switch to the next separation condition at appropriate time points. This reduces the pumping energy consumption and temperature control energy consumption caused by extending the adsorption equilibrium time or multiple elution cycles, while also reducing the risk of At-211 activity loss during the elution stage, which is beneficial to improving the usable activity output of the final formulation. Attached Figure Description

[0059] Figure 1 This is a flowchart of the At-211 separation process energy efficiency evaluation and optimization method provided in the embodiments of the present invention. Detailed Implementation

[0060] Exemplary embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.

[0061] like Figure 1 As shown, embodiments of the present invention propose a method for energy efficiency evaluation and optimization of the At-211 separation process, the method comprising:

[0062] The reaction solution containing At-211 is introduced into the separation unit filled with adsorbent material, and the adsorption and elution operation of At-211 is started. During the separation process, At-211 elution activity data and the corresponding separation runtime are collected at preset time intervals to form raw operation data.

[0063] Based on the original operating data, the At-211 separation process is divided into time periods according to a preset time interval, and the change in At-211 elution activity within each separation time period is correlated with the corresponding separation runtime to generate separation contribution data.

[0064] Based on the separation contribution data, the separation contribution of multiple adjacent separation time periods is compared and processed to determine its trend characteristics over time. Based on the trend characteristics, a stage judgment result is generated to indicate whether the separation process has entered a low separation contribution interval.

[0065] Based on the stage judgment results, when the separation process is determined to enter the low separation contribution range, the operating resource input required to continue to perform the current adsorption or elution operation is quantified by combining the current At-211 remaining activity data, and a cost assessment result of the operating cost per unit effective activity is generated.

[0066] The cost assessment result is compared with the preset cost threshold. When the cost assessment result exceeds the preset cost threshold, a separation process structure adjustment instruction is generated, and the corresponding separation process structure adjustment operation is executed according to the instruction. The separation process structure adjustment operation includes at least one of the following: prematurely terminating the current adsorption or elution step, skipping the subsequent separation time period, or switching to the next separation condition.

[0067] After completing the structural adjustment operation of the separation process, the acquisition of At-211 elution activity data and the generation of separation contribution are re-executed, so that the subsequent At-211 separation process can continue to carry out energy efficiency assessment and structural optimization under the updated separation structure.

[0068] In this embodiment of the invention, by simultaneously collecting elution activity data and separation runtime during the At-211 adsorption and elution separation process, and dividing the separation process into time periods according to a preset time interval, the separation process can be decomposed into multiple operating intervals with clear time boundaries. This provides basic data support for subsequent analysis of the operating status of the separation process, which helps to avoid the bias caused by relying solely on a single time point or overall statistical data to judge the separation effect.

[0069] By correlating the changes in At-211 elution activity with the corresponding separation runtime in each time period, separation contribution data is generated to characterize the separation contribution level in each time period. This allows for the quantitative expression of the actual output of different stages of the separation process within a unit runtime, thus distinguishing between the running stages that contribute more to the At-211 separation results and those that contribute less, providing a basis for the stage-based analysis of the separation process.

[0070] Based on this, by comparing the separation contribution of multiple adjacent separation time periods and combining the trend characteristics of the separation contribution over time to generate stage judgment results, it is possible to determine whether the separation process has entered the low separation contribution range by the changes over a continuous time period, avoiding the need to make separation status judgments based solely on instantaneous data of a single time period, and improving the reliability of separation process stage identification.

[0071] When the separation process is determined to have entered a low separation contribution range, the operational resource input required to continue the current adsorption or elution operation is quantified by combining the current At-211 remaining activity data, and an assessment result of the operational cost per unit of effective activity is generated. This allows the decision on whether to continue the subsequent operation of the separation process to simultaneously consider the relationship between the remaining available activity and the operational resource input, thereby avoiding the continued execution of separation operations with limited contribution when At-211 activity continues to decline.

[0072] Furthermore, by comparing the cost assessment results with a preset cost threshold, and performing the corresponding separation process structure adjustment operation when the threshold is exceeded, the separation process can terminate the current adsorption or elution step, skip subsequent separation time periods, or switch to the next separation condition at an appropriate time point. This allows the separation process to continue to conduct energy efficiency assessment and optimization under the updated structure, which helps to reduce the accumulation of ineffective operating time.

[0073] For example, in the application scenario of At-211 separation for radionuclide preparation, after the reaction solution is introduced into the separation unit, as the adsorption and elution process proceeds, the elution activity and runtime data are continuously collected at preset time intervals, and the separation contribution of each time period is generated. When the separation contribution shows a downward trend and enters the low separation contribution range for multiple consecutive time periods, the method combines the current remaining activity to assess the operating cost required to continue elution, and terminates the current elution step in advance when the cost exceeds a preset threshold. This ensures the purity of At-211 separation while avoiding the continued consumption of running time and resources in the subsequent low contribution stage, making it easier to reasonably control the separation process in actual production.

[0074] In a preferred embodiment of the present invention, after completing the structural adjustment operation of the separation process, the acquisition of At-211 elution activity data and the generation of separation contribution are re-executed, so that the subsequent At-211 separation process can continue to perform energy efficiency evaluation and structural optimization under the updated separation structure, including:

[0075] After completing the structural adjustment operation, the operating status of the separation unit is re-initialized and confirmed, and the elution activity monitoring is restarted under the new separation structure or separation conditions. The updated elution activity data and corresponding separation runtime data are continuously collected at preset time intervals consistent with the aforementioned steps. The newly collected operating data is input into the separation contribution generation process as new raw operating data, and the time period division, activity change processing, and separation contribution calculation are re-executed. In this way, the separation process can re-enter a complete energy efficiency assessment and optimization cycle after each structural adjustment, thereby realizing dynamic optimization control of the separation process.

[0076] In a preferred embodiment of the present invention, the method for setting the cost threshold includes:

[0077] Before the separation system is put into use, several typical separation operation scenarios are selected for test operation based on the half-life characteristics of At-211, the rated operating power of the separation unit, and the resource consumption per unit time. In each test operation scenario, the amount of operating resources consumed per unit time and the corresponding At-211 effective activity output are recorded, and the operating cost level corresponding to the unit effective activity under different operating conditions is determined accordingly. The cost level that can simultaneously meet the separation purity requirements and the operating resource consumption is within an acceptable range in the above test results is used as a reference for the cost threshold. Finally, the reference cost level is solidified into the cost threshold parameter in the separation control unit for comparison and judgment of the operating cost evaluation results in the subsequent separation process.

[0078] In a preferred embodiment of the present invention, based on the original operating data, the At-211 separation process is divided into time periods according to a preset time interval, and the change in At-211 elution activity within each separation time period is correlated with the corresponding separation runtime to generate separation contribution data, including:

[0079] Based on the original operating data, the At-211 separation process is divided into continuous time periods according to a preset time interval. The starting elution activity data, ending elution activity data, and separation runtime data corresponding to each separation time period are obtained to generate basic data for the time period.

[0080] Based on the basic data of the time period, the difference between the starting elution activity data and the ending elution activity data in each separation time period is processed to generate the elution activity change data for the corresponding separation time period.

[0081] Based on the elution activity change data, the elution activity change data is time-normalized to generate standardized activity change data that eliminates the influence of differences in separation runtime.

[0082] The standardized activity change data and the separation runtime data of the corresponding separation time period are jointly processed to generate initial separation contribution data that characterizes the unit operation contribution level of each separation time period.

[0083] Based on the initial separation contribution data, the initial separation contributions for multiple consecutive separation time periods are cumulatively corrected to generate separation contribution data for subsequent trend analysis.

[0084] In this embodiment of the invention, by dividing the At-211 separation process into multiple consecutive time periods according to a preset time interval, and obtaining the initial elution activity, the final elution activity, and the separation runtime corresponding to each time period, the separation process is refined into multiple independently analyzable operating intervals in the time dimension, which is beneficial to accurately reflect the changes in the operating status of the separation process at different stages.

[0085] Based on this, by calculating the changes in elution activity over different time periods and combining the separation runtime with time normalization of the changes, the activity outputs under different runtime conditions are made comparable, thereby avoiding imbalance in the evaluation of separation effect due to differences in time span.

[0086] Furthermore, by jointly processing the standardized activity change data with the separation runtime of the corresponding time period, and cumulatively correcting the initial separation contribution of multiple consecutive time periods, the generated separation contribution data can reflect the continuous output characteristics of At-211 during the separation process, which is beneficial to providing a stable data foundation for the trend analysis of the subsequent separation process.

[0087] In a preferred embodiment of the present invention, based on the initial separation contribution data, the initial separation contributions for multiple consecutive separation time periods are cumulatively corrected to generate separation contribution data for subsequent trend analysis, including:

[0088] After obtaining the initial separation contribution data corresponding to each separation time period, the initial separation contribution data is arranged in chronological order, and the initial separation contribution data corresponding to the earliest time period is used as the starting data for cumulative correction processing. On this basis, the initial separation contribution data corresponding to the next separation time period is combined with the cumulatively corrected contribution result of the previous time period, so that the contribution result of the next time period can reflect the continuous operation of multiple previous time periods. In this way, the contribution correction processing of multiple consecutive separation time periods is completed in sequence, so that the final separation contribution data simultaneously contains the operation contribution information of a single time period and the continuous output characteristics of the separation process in the time dimension. The cumulatively corrected separation contribution data is used as the input data for subsequent separation contribution trend analysis, thereby avoiding trend judgment based solely on the contribution data of a single time period.

[0089] In a preferred embodiment of the present invention, based on the separation contribution data, the separation contribution of multiple adjacent separation time periods is compared to determine its trend characteristics over time, and a stage determination result is generated based on the trend characteristics to indicate whether the separation process has entered a low separation contribution interval, including:

[0090] Based on the separation contribution data, the separation contribution data corresponding to multiple consecutive separation time periods are selected in chronological order to generate contribution sequence data for trend analysis.

[0091] Based on the contribution sequence data, sequential difference processing is performed on the separation contribution data corresponding to adjacent separation time periods to generate change direction data that characterizes the direction of change of separation contribution.

[0092] Based on the change direction data, determine whether the change direction of the separation contribution maintains a consistent structure within a preset number of consecutive separation time periods, and generate trend feature data of the continuous change of the separation contribution over time when it remains consistent.

[0093] Based on the trend feature data, the corresponding separation contribution value range is processed for range determination. When the separation contribution value corresponding to the trend feature data is continuously in the preset low separation contribution range, a stage determination result is generated to indicate that the separation process has entered the low separation contribution range.

[0094] In this embodiment of the invention, by selecting the separation contribution data corresponding to multiple consecutive separation time periods in chronological order, a contribution sequence for trend analysis is constructed, so that the changes in separation contribution can be continuously reflected in the time dimension.

[0095] Based on this, by performing sequential difference processing on the separation contribution of adjacent time periods, the direction of change of the separation contribution between adjacent time periods is clarified, and the consistency of the direction of change is judged by combining a preset number of continuous time periods, so that the trend characteristics of the separation contribution are based on the continuous changes of multiple time periods, rather than the instantaneous result of a single time point.

[0096] By further determining the numerical range corresponding to the separation contribution, a stage determination result is generated when the separation contribution corresponding to the trend feature continues to be in the preset low separation contribution range. This allows the separation process to be identified by both time continuity and numerical range conditions, thus providing a basis for subsequent operation decisions of the separation process.

[0097] In a preferred embodiment of the present invention, based on trend feature data, interval determination processing is performed on the corresponding separation contribution value interval. When the separation contribution corresponding to the trend feature data remains within a preset low separation contribution interval, a stage determination result is generated to indicate that the separation process has entered the low separation contribution interval, including:

[0098] After obtaining trend feature data reflecting the change of separation contribution over time, the separation contribution value corresponding to the trend feature data is compared segment by segment with the pre-set separation contribution interval. The separation contribution interval is divided into at least one normal contribution interval and at least one low separation contribution interval based on historical separation operation data. When the separation contribution values ​​corresponding to multiple consecutive separation time periods all fall into the low separation contribution interval, it is determined that the current trend feature meets the judgment condition of the low separation contribution interval. After confirming that the judgment condition is met, a stage judgment result is generated to indicate that the separation process has entered the low separation contribution interval, and this stage judgment result is used as the triggering basis for subsequent operation cost assessment steps.

[0099] In a preferred embodiment of the present invention, the method for setting the low separation contribution interval includes:

[0100] Before the separation system is put into normal operation, select a separation unit, adsorption material and elution conditions that are consistent with the actual application conditions, perform at least one complete At-211 separation process, and collect the separation contribution data corresponding to each time period according to the preset time interval during the separation process;

[0101] After obtaining the separation contribution data, the separation contribution of each separation time period was statistically organized in chronological order, and the separation contribution data corresponding to the initial stage of the separation process was used as a reference contribution level to characterize the separation contribution under the condition of high adsorption or elution efficiency.

[0102] Based on the reference contribution level, the range of values ​​where the separation contribution is significantly lower than the reference contribution level is determined, and the interval of separation contribution corresponding to this range is set as the low separation contribution interval, so that this interval can reflect the activity output status per unit operating time in the later stage of the separation process or the efficiency decline stage.

[0103] The low separation contribution interval is used as a fixed interval parameter for stage determination, and is used in subsequent separation processes to determine whether the separation contribution remains at a low level, thereby providing a basis for stage identification in the separation process.

[0104] In a preferred embodiment of the present invention, based on the stage determination result, when the separation process is determined to have entered a low separation contribution range, the operational resource input required to continue performing the current adsorption or elution operation is quantified by combining the current At-211 residual activity data, generating a cost assessment result for the operational cost per unit effective activity, including:

[0105] Based on the stage judgment results, when the separation process enters the low separation contribution interval, the At-211 residual activity data at the corresponding time node is obtained to generate the current residual activity data;

[0106] Based on the current remaining activity data and the corresponding time points, the decay estimation process is performed on the changes in At-211 activity during the subsequent separation period to generate usable activity assessment data for the subsequent separation stage.

[0107] Based on the current operating status of the separation unit, determine the separation runtime and corresponding operating resource input required to continue the current adsorption or elution operation in subsequent separation stages, and generate operating resource requirement data;

[0108] By jointly processing operational resource demand data and available activity assessment data, a cost assessment result is generated that characterizes the operational cost required per unit of effective activity in the subsequent separation stage.

[0109] In this embodiment of the invention, when the separation process is determined to have entered a low separation contribution range, the remaining At-211 activity data at the corresponding time point is obtained so that the evaluation of subsequent separation operations can be carried out based on the current available activity level.

[0110] Based on this, by performing attenuation estimation on the changes in At-211 activity during the subsequent separation period, assessment data reflecting the available activity level in the subsequent separation stage is generated, enabling the feasibility of the subsequent separation process to be predicted in the time dimension.

[0111] Meanwhile, by combining the operating status of the separation unit, the separation runtime and corresponding operating resource input required to continue the current adsorption or elution operation are determined. The operating resource requirements are then combined with the available activity assessment data to generate the operating cost required per unit of effective activity. This allows the decision on whether to continue the separation process to simultaneously consider the relationship between the remaining activity level and the operating resource input, which is beneficial for providing a quantitative basis for adjusting the separation process structure.

[0112] In a preferred embodiment of the present invention, based on the current operating state of the separation unit, the separation runtime and corresponding operating resource input required to continue performing the current adsorption or elution operation in subsequent separation stages are determined, and operating resource requirement data is generated, including:

[0113] After determining the time range corresponding to the subsequent separation stage, the operating parameter information of the separation unit under the current separation conditions is obtained. The operating parameter information includes at least the fluid transport power, temperature control power, and operating power of related auxiliary equipment per unit time. Based on the operating parameter information and the expected running time of the subsequent separation stage, the consumption of various operating resources in the subsequent separation stage is cumulatively estimated so that the amount of operating resources input can reflect the overall resource consumption level required to maintain the current adsorption or elution operation within this time range. The cumulatively estimated amount of operating resources input is integrated with the corresponding separation running time to form operating resource demand data to characterize the resource demand of the subsequent separation stage.

[0114] In a preferred embodiment of the present invention, a cost assessment result is generated by jointly processing operational resource requirement data and available activity assessment data to characterize the operational cost required per unit of effective activity in the subsequent separation stage, including:

[0115] After obtaining the operational resource requirements data and corresponding available activity assessment data for the subsequent separation phase, the operational resource requirements data and available activity assessment data are matched to establish a correlation between the operational resource consumption level and the available effective activity output. Based on this, the operational resource requirements data are normalized so that they can reflect the resource level required to obtain a unit of effective activity in the subsequent separation phase. Through the above processing, a cost assessment result is generated to characterize the operational cost per unit of effective activity in the subsequent separation phase.

[0116] In a preferred embodiment of the present invention, standardized activity change data and separation runtime data for corresponding separation time periods are jointly processed to generate initial separation contribution data characterizing the unit runtime contribution level for each separation time period, including:

[0117] Based on the separated runtime data, the runtime is grouped into at least two runtime categories, and a corresponding contribution processing rule is established for each runtime category.

[0118] Within each runtime category, the standardized activity change data for the corresponding separated time period are subjected to interval mapping processing to generate intermediate contribution data that reflects the activity output characteristics under that runtime category.

[0119] Based on the intermediate contribution data, cross-category calibration is performed on the contribution results between different runtime categories to generate calibrated intermediate contribution data.

[0120] Based on the intermediate contribution data after calibration, initial separation contribution data characterizing the unit operational contribution level for each separation time period is generated.

[0121] In this embodiment of the invention, by grouping each separation time period according to the separation runtime and establishing corresponding contribution processing rules for different runtime categories, the separation process forms a structured distinction in the runtime dimension, which helps to avoid the activity output under different runtime conditions being simply treated the same.

[0122] Based on this, by performing interval mapping on the standardized activity change data within each runtime category, the activity output characteristics within the same runtime category can be uniformly represented, thereby reducing the impact of runtime differences on the evaluation results of separation contribution.

[0123] Furthermore, by performing cross-category calibration on the intermediate contribution results between different runtime categories, the separation contribution results obtained under different operating conditions can be compared on a unified scale. Finally, initial separation contribution data characterizing the unit operating contribution level of each separation time period is generated, which is beneficial to improving the stability and consistency of separation contribution data under complex operating conditions.

[0124] In a preferred embodiment of the present invention, cross-category calibration processing is performed on the contribution results between different runtime categories based on intermediate contribution data to generate calibrated intermediate contribution data, including:

[0125] After completing the interval mapping process within each runtime category, the intermediate contribution data corresponding to different runtime categories are aggregated into a unified dataset, and the runtime category to which each intermediate contribution data belongs is recorded. Based on this, a pre-determined baseline runtime category is selected as the calibration reference category, and the intermediate contribution data corresponding to the baseline runtime category is used as the calibration benchmark. Subsequently, the intermediate contribution data in other runtime categories are calibrated to ensure that they are consistent with the intermediate contribution data of the baseline runtime category in terms of numerical scale, thereby eliminating the systematic bias introduced by the differences in runtime categories. Through the above cross-category calibration process, the intermediate contribution data obtained under different runtime conditions can be compared under a unified standard to generate calibrated intermediate contribution data.

[0126] In a preferred embodiment of the present invention, initial separation contribution data characterizing the unit operational contribution level for each separation time period is generated based on the intermediate contribution data after calibration processing, including:

[0127] After obtaining the intermediate contribution data after cross-category calibration, the intermediate contribution data is organized according to the separation time period, so that each separation time period corresponds to a set of calibrated contribution data. On this basis, the calibrated intermediate contribution data within the same separation time period are summarized to generate the unit operating contribution result corresponding to that separation time period. Through the above processing, the generated initial separation contribution data can directly reflect the unit operating contribution level of each separation time period under the same operating condition scale, and serve as the input data for subsequent cumulative correction processing.

[0128] In a preferred embodiment of the present invention, based on the change direction data, it is determined whether the change direction of the separation contribution maintains a consistent structure within a preset number of consecutive separation time periods, and if it remains consistent, trend feature data of the continuous change of the separation contribution over time is generated, including:

[0129] Based on the data on the direction of change, construct a sequence of the direction of change in chronological order;

[0130] Based on the sequence of change directions, the consistency of the change directions of adjacent separation time periods is determined segment by segment, and local consistency results between each separation time period are generated.

[0131] Based on the local consistency results, the consistency status within multiple consecutive separation time periods is cumulatively determined to generate an overall consistency assessment result.

[0132] When the overall consistency assessment results meet the preset continuous consistency conditions, it is determined that the direction of change of the separation contribution remains consistent within the continuous separation time period;

[0133] After ensuring that the direction of change in the separation contribution remains consistent, trend feature data characterizing the continuous change of the separation contribution over time is generated.

[0134] In this embodiment of the invention, by constructing a sequence of changes in the direction of separation contribution in chronological order, the relationship of changes in separation contribution over a continuous time period can be expressed in sequence form, which is beneficial for reflecting the dynamic changes in the separation process.

[0135] Based on this, by performing segment-by-segment consistency determination on the direction of change of adjacent separation time periods and generating local consistency results, the judgment of the direction of change of separation contribution is no longer limited to a single time period, but is based on the continuous relationship between adjacent time periods.

[0136] Furthermore, by accumulating and judging the consistency status over multiple consecutive time periods and generating an overall consistency assessment result, the generation of the separation contribution trend characteristics is based on multi-level consistency judgment, thereby reducing misjudgments caused by short-term fluctuations and making the trend characteristics of the separation contribution change over time more consistent with the overall operating status of the actual separation process.

[0137] In a preferred embodiment of the present invention, based on the local consistency results, the consistency status within multiple consecutive separation time periods is cumulatively determined to generate an overall consistency evaluation result, including:

[0138] After obtaining the local consistency results between adjacent separation time periods, the local consistency results are arranged in chronological order, and the local consistency result corresponding to the earliest time period is used as the starting state for cumulative judgment. On this basis, the local consistency results of the next time period are merged with the cumulative consistency state of the previous time period to make the consistency state of the next time period reflect the consistency of the aforementioned multiple time periods. Through the above-mentioned segment-by-segment cumulative judgment method, an overall consistency assessment result is generated to characterize the overall consistency level of multiple consecutive separation time periods, thereby avoiding trend judgment based solely on the consistency results of a single adjacent time period.

[0139] In a preferred embodiment of the present invention, after determining that the direction of change of the separation contribution remains consistent, trend feature data characterizing the continuous change of the separation contribution over time is generated, including:

[0140] After the overall consistency assessment results meet the preset continuous consistency conditions, it is confirmed that the direction of change of the separation contribution is consistent within the continuous separation time period. On this basis, the information on the direction of change of the separation contribution within the continuous separation time period is summarized and processed to form trend description data that can reflect the continuous change of the separation contribution over time. Through the above processing, the change behavior of the separation contribution in multiple time periods is abstracted into unified trend feature data, and this trend feature data is output for interval judgment and decision analysis in the subsequent separation stage determination process.

[0141] In a preferred embodiment of the present invention, the method for setting continuous consistency conditions includes:

[0142] After determining the order of the direction of change of the separation contribution, the direction of change of the separation contribution between adjacent separation time periods is statistically analyzed, and adjacent time periods with consistent change directions are used as the basic unit for consistency determination.

[0143] Based on this, according to the time scale of the separation process and the actual fluctuation characteristics of the change in the separation contribution, the number of separation time periods that need to continuously meet the consistency judgment is preset so that the number can cover at least one complete separation operation stage, thereby avoiding the triggering of trend judgment due to short-term fluctuations in a single time period.

[0144] When the direction of change of the separation contribution remains consistent within a preset number of consecutive separation time periods, it is determined that the continuous consistency condition is met, and this determination result is used as the trigger condition for generating trend feature data.

[0145] By setting the above, the trend determination of the separation contribution is based on the consistent direction of change over multiple consecutive time periods, thereby improving the consistency between the trend identification results and the actual operation status of the separation process.

[0146] In a preferred embodiment of the present invention, based on the current remaining activity data and the corresponding time point, the decay estimation processing is performed on the change of At-211 activity during the subsequent separation period to generate usable activity assessment data for the subsequent separation stage, including:

[0147] Based on the time nodes corresponding to the current remaining activity data, determine multiple consecutive separation time periods corresponding to the subsequent separation phase, and generate corresponding time span data for each separation time period;

[0148] The current remaining activity data is used as the initial activity data for the first separation time period;

[0149] For each separation time period, based on the corresponding initial activity data of the stage and the time span data of the separation time period, the activity decay ratio of At-211 in the separation time period is determined, and the initial activity data of the stage is updated accordingly to generate the stage remaining activity data corresponding to the separation time period.

[0150] The residual activity data generated in the previous separation period is used as the initial activity data in the next separation period, and the activity decay estimation process for multiple consecutive separation periods is completed in sequence.

[0151] Based on the remaining activity data corresponding to each separation time period, the activity change process in subsequent separation stages is summarized to generate available activity assessment data that reflects the overall available activity level in subsequent separation stages.

[0152] In this embodiment of the invention, by dividing the subsequent separation stage into multiple consecutive separation time periods based on the time node corresponding to the current remaining activity data, and generating corresponding time span data for each separation time period, the subsequent separation stage is clearly divided into multiple operating intervals with clear boundaries in the time dimension. This provides a structured time basis for the analysis of At-211 activity changes over time, which helps to avoid the problem of coarsening of activity assessment caused by treating the subsequent separation stage as a whole.

[0153] By using the current remaining activity data as the initial activity data for the first separation period, and using the remaining activity data generated in the previous period as the initial activity data for the next period in subsequent separation periods, the change in At-211 activity in subsequent separation stages can be estimated in a continuously updated manner. This reflects the continuous characteristics of the natural decay of radionuclides over time during actual separation, and avoids the evaluation bias caused by independent calculations between different separation periods.

[0154] Based on this, by combining the corresponding initial activity data of the separation period with the time span data of that separation period for each separation time period, the activity decay of At-211 in that time period is estimated and the remaining activity data of the period is generated. This allows the available activity level in each separation time period to be characterized segment by segment, thereby providing clear data support for the effective activity changes in each time period in the subsequent separation stages.

[0155] Furthermore, by summarizing the remaining activity data corresponding to each separation time period, assessment data reflecting the overall available activity level in the subsequent separation stages is generated. This enables the operational decisions for subsequent separation operations to be based on the activity changes throughout the entire subsequent separation stages, rather than relying solely on single time points or instantaneous activity data. This improves the rationality of the feasibility assessment of subsequent separation stages under the condition of a short At-211 half-life.

[0156] Embodiments of the present invention also provide an energy efficiency assessment and optimization system for the At-211 separation process, the system comprising:

[0157] The data acquisition module is used to collect At-211 elution activity data and corresponding separation runtime at preset time intervals during the At-211 separation process to form raw operation data;

[0158] The separation contribution generation module is used to divide the At-211 separation process into time periods according to preset time intervals based on the original operating data, and to correlate the change in At-211 elution activity with the corresponding separation runtime in each separation time period to generate separation contribution data.

[0159] The trend analysis and stage determination module is used to compare the separation contribution of multiple adjacent separation time periods based on the separation contribution data, determine the trend characteristics of its change over time, and generate a stage determination result based on the trend characteristics to indicate whether the separation process has entered a low separation contribution range.

[0160] The cost assessment module is used to quantify the operational resource input required to continue the current adsorption or elution operation based on the stage judgment results when the separation process enters the low separation contribution range, combined with the current At-211 remaining activity data, and generate a cost assessment result of the operational cost per unit effective activity.

[0161] The structural adjustment decision module is used to compare the cost assessment result with the preset cost threshold. When the cost assessment result exceeds the preset cost threshold, a separation process structural adjustment instruction is generated, and the corresponding separation process structural adjustment operation is executed according to the instruction. The separation process structural adjustment operation includes at least one of the following: prematurely terminating the current adsorption or elution step, skipping the subsequent separation time period, or switching to the next separation condition.

[0162] The structural adjustment execution module is used to trigger the data acquisition module and the separation contribution generation module to re-execute the acquisition of At-211 elution activity data and the generation of separation contribution after the structural adjustment operation of the separation process is completed, so that the subsequent At-211 separation process can continue to carry out energy efficiency assessment and structural optimization under the updated separation structure.
