Description

Technical Field

[0001] The invention relates to the field of nuclear power experience feedback, and in particular to a nuclear power company management requirement effectiveness judgment system and judgment method. Background Art

[0002] Management requirements are an important tool for nuclear power companies to conduct group plant experience feedback. By proposing common management requirements to prevent the recurrence of events, each nuclear power plant organizes an investigation and feedbacks the investigation results within the specified time. Identifying the effectiveness of the implementation of management requirements in nuclear power plants is an important link in judging the effectiveness of group plant experience feedback. Management requirements are generally proposed for the causes, failure points or manifestations of events. By identifying whether the causes of new events in nuclear power plants are similar to existing management requirements, it is a means to identify the effectiveness of management requirements and judge whether the management requirements are effective.

[0003] In current practice, in order to identify whether a management requirement is valid, power company personnel need to find events that have a specific relationship with the management requirement, manually input some search information in the experience feedback platform, and manually screen the search results. In addition, power company personnel need to be familiar with historical management requirements.

[0004] In the existing technology, there are limitations in identifying whether management requirements are effective. First, when setting search conditions, personnel can only perform matching queries based on the search condition fields preset by the experience feedback platform. The search dimension is single, and the comprehensiveness and convenience of information retrieval are insufficient; secondly, the workload of retrieval and screening is large, and personnel often need to set search conditions for each management requirement one by one, and identify them one by one in the large number of retrieved results. This method is inefficient and prone to omissions; judging whether an event is related to management requirements is highly dependent on the work experience of personnel, and may make wrong judgments due to information interference, negligence and other factors, and lacks quantitative standards, which is highly subjective. Summary of the invention

[0005] The present invention provides a method for measuring the depleted zinc content in a boron system of a nuclear power plant, which is used to solve the problem in the prior art that effectiveness suggestions for management requirements require manual screening, resulting in comprehensive steps, reliance on personnel's work experience and a large workload.

[0006] The technical solution of the present invention is as follows:

[0007] The invention proposes a management requirement validity judgment system for a nuclear power company. The system comprises a management requirement information extraction module, a structured management requirement database, an event report information extraction module, a data judgment module and a similarity calculation module. The management requirement information extraction module extracts structured fields of management requirement data. The structured management requirement database is used to store management requirement data extracted by the management requirement information extraction module and problems targeted by the management requirements. The event report information extraction module preprocesses text data of the event report. The data judgment module performs semantic similarity calculation on the preprocessed event report and the management requirements in the structured management requirement database to obtain similarity calculation scores between the event report and the management requirements. The similarity calculation module sets a validity time judgment range and a validity judgment threshold, the similarity calculation module screens management requirements within the validity time judgment range, compares the similarity calculation scores between the management requirements and the event report with the validity judgment threshold, and feeds back management requirements with similarity calculation scores greater than the validity judgment threshold to users.

[0008] In some embodiments, the management requirement data is extracted by an information extraction module, and after manually summarizing the issues addressed by the management requirements and eliminating management requirements that do not require effectiveness evaluation, they are stored in a structured management requirement database.

[0009] In some embodiments, the event report information extraction module performs preprocessing, specifically: the event report information extraction module directly extracts the structured fields of the text data of the event report, and uses file summarization technology to extract key points from the unstructured fields of the text data of the event report; the event report information extraction module uses nuclear power professional vocabulary, general vocabulary, synonym vocabulary, etc. to normalize and standardize the non-standard expressions and the same pronouns in the text data; the event report information extraction module performs text segmentation and vectorization on the extracted and standardized text data, and performs database indexing processing.

[0010] In some embodiments, the data judgment module calculates the semantic similarity between the event cause of the event report and the problem addressed by the management requirement, and obtains a similarity calculation score between the event cause and the problem addressed by the management requirement.

[0011] In some embodiments, the similarity calculation module selects management requirements within the validity time judgment range, specifically including: setting the validity time, selecting management requirements that meet the requirements within the validity time, and the requirements include: the management requirements are valid; the management requirement release date is within the event validity judgment time range; the management requirement objects include the power plant where the event occurred; the management requirements have been executed.

[0012] In some embodiments, the validity time judgment range and the validity judgment threshold can be adjusted according to the actual management of the nuclear power company.

[0013] The present invention proposes a method for judging the effectiveness of management requirements of a nuclear power company, the method comprising:

[0014] Step 1: Extract and manually organize the management requirement information through the management requirement information extraction module to build a structured management requirement database;

[0015] Step 2: The event report information extraction module pre-processes the new event data of the nuclear power plant;

[0016] Step 3: The data judgment module calculates the semantic similarity between the preprocessed new event report of the nuclear power plant and the management requirements of the structured management requirements database, and obtains the similarity calculation score between the management requirements and the new event report of the nuclear power plant;

[0017] Step 4: The similarity calculation module sets the validity time judgment range and the validity judgment threshold, and screens the management requirements that meet the validity time judgment range;

[0018] Step 5: The similarity calculation module makes a validity judgment on the management requirements that meet the validity time judgment range, and provides feedback on the management requirements that may be insufficient in validity.

[0019] In some embodiments, step one specifically includes:

[0020] Step 1.1: The management requirement information extraction module extracts the structured fields of the management requirement data;

[0021] Step 1.2: Manually organize the management requirements data, summarize the issues addressed by the management requirements, and eliminate the management requirements that do not need to be evaluated for effectiveness;

[0022] Step 1.3: Store the management requirement data extracted by the management requirement information extraction module and manually sorted into the structured management requirement database.

[0023] In some embodiments, the data judgment module in step three calculates the semantic similarity between the preprocessed new event report of the nuclear power plant and the management requirements of the structured management requirements database, specifically, calculates the semantic similarity between the event cause of the new event report of the nuclear power plant and the problems addressed by the management requirements of the structured management requirements database.

[0024] In some embodiments, step five specifically includes: the similarity calculation module selects the similarity calculation score of the management requirement that meets the validity time judgment range and compares it with the validity judgment threshold. If the similarity calculation score of the management requirement is greater than the validity judgment threshold, the management requirement is fed back to the user.

[0025] The implementation of the present invention has the following beneficial effects:

[0026] The present invention proposes a system and method for judging the effectiveness of management requirements of a nuclear power company. The present invention constructs a structured management requirement database through a management requirement information extraction module, sorts out the problems to be solved by the management requirements, and uses a data judgment module and a similarity calculation module to automatically calculate the similarity between new events and the problems targeted by the management requirements, and provides a measurable judgment standard, so that the judgment of the effectiveness of the management requirements is more intelligent, efficient and accurate. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Figure 1 The present invention is a flowchart of a method for determining the effectiveness of management requirements of a nuclear power company proposed in an embodiment of the present invention. DETAILED DESCRIPTION

[0028] The technical solution of the present invention is described clearly and completely below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1 As shown, the present invention proposes a management requirement effectiveness judgment system for a nuclear power company, which includes a management requirement information extraction module, a structured management requirement database, an event report information extraction module, a data judgment module and a similarity calculation module.

[0030] The management requirement information extraction module uses data extraction tools and related interfaces to extract the management requirement data in the experience feedback platform according to the rules. The existing structured fields in the experience feedback platform can be directly extracted, including the management requirement number, description, release date, object, etc.

[0031] The structured management requirements database is used to store processed management requirements data. The management requirements data is extracted by the information extraction module, and after manually summarizing the issues addressed by the management requirements and eliminating management requirements that do not need to be evaluated for effectiveness, they are stored in the structured management requirements database.

[0032] The event report information extraction module uses data extraction tools and related interfaces to extract the text data of the event report corresponding to the new event in the nuclear power plant experience feedback platform (referred to as "new event report") according to the rules. The extraction rules are as follows: the existing structured fields in the experience feedback platform (such as the power plant, event theme, etc.) can be directly extracted; unstructured fields (such as direct causes, root causes, and contributing causes in the report document) are extracted using text summarization and other technologies to extract the key points. The event report information extraction module uses nuclear power professional thesaurus, general thesaurus, synonym thesaurus, etc. to normalize and standardize the non-standard expressions and the same referents in the text data; the event report information extraction module performs text segmentation and vectorization on the extracted and standardized text data, and performs database indexing.

[0033] The data judgment module uses a semantic similarity calculation tool pre-trained with the nuclear power corpus to calculate the semantic similarity between the event causes (including direct causes, root causes, and contributing causes) of the new event reports extracted by the event report information extraction module and the issues targeted by the management requirements of the structured management requirements database, and obtains the similarity calculation score between the event reports and the issues targeted by the management requirements.

[0034] The similarity calculation module sets an adjustable validity time judgment range according to the release time and object of the management requirements, and screens the management requirements within the validity time judgment range, specifically including: setting the validity time, selecting the management requirements that meet the requirements within the validity time, and the requirements include: 1. The management requirements are valid; 2. The release date of the management requirements is within the event validity judgment time range; 3. The management requirements object includes the power plant where the event occurred; 4. The management requirements have been executed. At the same time, the similarity calculation module sets an adjustable management requirement validity judgment threshold according to the actual management of the nuclear power company as a standard for judging whether the new event has a high correlation with the management requirements. The similarity calculation module compares the similarity calculation score of the management requirements and the new event report within the validity time judgment range with the validity judgment threshold. When the similarity score of a certain management requirement for the problem and the new event is greater than the set judgment threshold, it is determined that the effectiveness of the management requirement in the power plant may be insufficient.

[0035] The system monitors the similarity calculation results between new events and management requirements for problems every day. When the similarity score between a management requirement and a new event is greater than the set judgment threshold, the computer system will prompt to remind the possible lack of effectiveness of the management requirement, and relevant professionals will intervene to analyze and handle the problem.

[0036] The present invention proposes a method for judging the effectiveness of management requirements of a nuclear power company, the method comprising:

[0037] Step 1: Build a structured management requirement database by extracting and manually organizing the management requirement information through the management requirement information extraction module.

[0038] Step 1.1: The management requirement information extraction module extracts the structured fields of the management requirement data.

[0039] Step 1.2: Manually organize the management requirements data, summarize the issues addressed by the management requirements, and eliminate management requirements that do not require effectiveness evaluation.

[0040] Step 1.3: Store the management requirement data extracted by the management requirement information extraction module and manually sorted into the structured management requirement database.

[0041] Step 2: The event report information extraction module preprocesses the new event data of the nuclear power plant. The preprocessing includes: the event report information extraction module extracts and processes the new event report text data in the experience feedback platform. Among them, the existing structured fields in the experience feedback platform (such as the power plant, event theme, etc.) can be directly extracted; unstructured fields (such as direct causes, root causes, and contributing causes in the report document) are extracted using text summarization and other technologies. Then, the event report information extraction module uses nuclear power professional vocabulary, general vocabulary, synonym vocabulary, etc. to normalize, standardize or replace the non-standard expressions and the same referential terms in the text data. Finally, the event report information extraction module performs text segmentation and vectorization on the above-processed text data, and performs database indexing processing to ensure the operating efficiency when similarity calculations are carried out later.

[0042] Step 3: The data judgment module calculates the semantic similarity between the preprocessed new event report of the nuclear power plant and the management requirements in the structured management requirements database to obtain the similarity calculation score between the management requirements and the new event report of the nuclear power plant, specifically including: after the new event report of the nuclear power plant is preprocessed, the semantic similarity model pre-trained with the nuclear power corpus is used to calculate the semantic similarity between the event cause (including direct cause, root cause, and contributing cause) of the new event report and the problems targeted by each management requirement in the structured management requirements database to obtain the similarity calculation score between the event cause and the problem targeted by the management requirement.

[0043] Step 4: The similarity calculation module sets the validity time judgment range and validity judgment threshold, and screens the management requirements that meet the validity time judgment range, including: according to the release time and object of the management requirements, according to the set adjustable validity time judgment range, and whether the management requirements have been implemented in the power plant and other objective conditions, screen out the management requirements that need to be compared with the validity judgment threshold. For the power plant of the new event, the management requirements that need to be judged for validity must meet all of the following rules: 1. The management requirements are valid; 2. The release date of the management requirements is within the event validity judgment time range; 3. The management requirements include the power plant where the event occurred; 4. The management requirements have been executed and are in a closed state. According to the actual management of the nuclear power company, an adjustable validity judgment threshold is set to determine whether the new event has a high correlation with the management requirements for the problem.

[0044] Step 5: The similarity calculation module makes a validity judgment on the management requirements that meet the validity time judgment range, and provides feedback on the management requirements that may have insufficient validity, specifically including: comparing the similarity calculation score of the management requirements that meet the validity time judgment range and the new event report of the nuclear power plant with the judgment threshold. When the similarity score between a certain management requirement and the new event report of the nuclear power plant is greater than the set judgment threshold, it is judged that the effectiveness of the management requirement in the power plant may be insufficient. When the similarity score between the problem and the new event of a certain management requirement is greater than the set judgment threshold, the system will prompt to remind the management requirement of the possible lack of validity, and relevant professionals will intervene to analyze and handle it.

[0045] The above embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention patent shall be subject to the attached claims.
