AI Technical Summary

Technical Problem

Existing decontamination technologies for nuclear power plant primary systems, particularly heavy water reactors, struggle to monitor decontamination status in real time and quantitatively assess contamination levels at key points, leading to incomplete decontamination, increased radiation exposure risks, and excessive waste generation.

Method used

A radiation monitoring system with multiple detectors installed on the primary system's pipes, using scintillators and optical sensors, shielded and collimated to measure radiation dose, and a central processing unit for real-time data analysis, calculating residual dose ratios and reduction rates to determine decontamination completion.

Benefits of technology

Enables real-time, quantitative assessment of decontamination status, reducing unnecessary reprocessing, minimizing waste, and ensuring worker safety by identifying uneven decontamination early and optimizing chemical use.

Abstract

The present invention relates to a radiation monitoring system and a radiation monitoring method of the system. A radiation monitoring system according to an embodiment of the present invention may include a plurality of radiation detection devices installed on the outer surface of pipes included in the primary system of a nuclear power plant and designated major components to detect radiation at each location, and a radiation monitoring device that stores and analyzes radiation-related data collected from the plurality of radiation detection devices by time synchronization, tags a time point corresponding to a decontamination process step, sets an ROI section corresponding to a gamma ray energy peak by nuclide based on gamma ray spectrum data acquired at each step, analyzes the gamma ray spectrum for each set ROI section, calculates the residual dose ratio (DRR), reduction rate (dR / dt), and ROI analysis value by nuclide based on the analysis results, and automatically determines whether decontamination is completed according to whether the calculated indicator satisfies a preset threshold condition.
