乏燃料后处理厂核应急评价与决策支持系统设计

Abstract

Abstract: A nuclear emergency assessment system should be established to deal with the potential accidents such as criticality, radioactive material leakage, fire and explosion which could occur in spent fuel reprocessing plant. This paper introduces the design of a real-time three-dimensional visualization system for nuclear emergency assessment and decision support for five typical accidents in spent fuel reprocessing plant. The system is capable of diagnosising emergency conditions on real-time based on dynamic process monitoring data, calculating the source terms released into the plant and environment, carrying out emergency response process management based on emergency plan, and implementing protection action analysis for protecting staff and the public. The system can realize the dynamic display of emergency evaluation results and response process based on three-dimensional visualization technology. The system was developed for the emergency assessment and decision support of the spent fuel reprocessing plant, and will improve the emergency preparedness and response capacity.

Key words: spent fuel reprocessing plant, nuclear emergency, emergency assessment, decision support
