Radioactive Workpiece Decontamination via Data-Driven Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The decontamination of radioactively contaminated workpieces is prolonged and costly due to manual labor and radiation exposure, with employees being exposed to radiation for extended periods, and the process is inefficient, often requiring repeated cleaning and measurement steps.
Innovation Solution
The method involves using data technology to process measurement results from one workpiece to inform the cleaning of subsequent workpieces, allowing for more targeted and efficient cleaning by aligning cleaning efforts based on geometric and contamination data, and incorporating automated and parallel processing steps to reduce exposure and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual cleaning and measurement steps are used for each workpiece, then thorough decontamination can be achieved, but the working time and radiation exposure of employees increase significantly
Solution Approach 1:
The system performs preliminary measurement and data processing on current workpieces to generate control parameters for subsequent workpieces before actual cleaning occurs. This allows the next workpiece to be prepared with optimized cleaning parameters in advance, reducing waiting time and radiation exposure while maintaining thoroughness.
Solution Approach 2:
Measurement results from current workpieces are fed back into the data processing system to continuously optimize control parameters for subsequent workpieces. This feedback loop enables the system to learn from each workpiece and improve cleaning efficiency for the next one, reducing overall processing time while maintaining decontamination quality.
2Reliability
If repeated cleaning and measurement steps are performed to ensure compliance, then radiation safety standards are met, but the decontamination process is extended and costs increase
Solution Approach 1:
The system performs preliminary measurements and generates control parameters before full cleaning cycles, allowing for targeted cleaning that is more likely to achieve compliance on the first attempt. This reduces the need for repeated cleaning and measurement cycles, thereby improving throughput while maintaining safety compliance.
Solution Approach 2:
The data processing system dynamically adjusts cleaning parameters based on measurement results from current workpieces. By optimizing parameters such as cleaning intensity, duration, and method selection for each subsequent workpiece, the system achieves compliance more efficiently, reducing the frequency of repeated cycles and increasing overall productivity.
3Reliability
If comprehensive cleaning is performed on all workpieces, then decontamination standards are met, but the process becomes economically costly due to extended processing time
Solution Approach 1:
The system applies different cleaning parameters to different workpieces based on their specific contamination characteristics. By analyzing measurement data from current workpieces and generating tailored control parameters for subsequent ones, the system avoids applying uniform comprehensive cleaning to all workpieces, thereby reducing economic costs while maintaining compliance with decontamination standards.
