摘要: 本文介绍了我国首次集成开发的铀浓缩设施核应急实时评价系统。系统针对铀浓缩设施可以实时评价核临界事故和UF6泄漏事故的辐射影响。系统可根据事故γ报警仪剂量率读数估算核临界裂变次数,并自动评价核临界事故后果。针对UF6烟羽的重气特性,将重气模型与高斯烟羽模型相结合,可更准确地模拟UF6的扩散过程。系统的开发解决了铀浓缩设施应急准备和响应一直缺乏的技术支持能力。

Abstract: The paper introduces the first integrated real-time assessment system for nuclear emergency at uranium enrichment facility in China. The system can assess the radiation effects of nuclear criticality accidents and UF6 leakage accidents in a real-time manner. It estimates nuclear criticality fission number according to the readings of γ alarm dose rate instrument, and automatically assess the nuclear criticality consequence. Focusing on the heavy gas characteristic of UF6 plume, the system combines the heavy gas model with the Gaussian model, thus simulates more accurately the UF6 diffusion process. The development of the system solves the problem of lacking the technical support capability for uranium enrichment facility in emergency preparedness and response.

Key words: uranium enrichment facility, nuclear emergency assessment system, protective action
