剂量率在严重事故下乏燃料损伤评价系统中的应用
发布时间：2019-08-12 16:46
【摘要】：本文介绍了一种利用剂量率监测值评价严重事故时乏燃料损伤程度的方法。分别计算不同富集度、燃耗的乏燃料100%包壳损伤的剂量率作为数据库,根据停堆时间、事故的发生时间与实际监测值来评估乏池中燃料的损伤份额,实现了对乏池中不同类型燃料的损伤程度的差异化评估。本文方法已应用于秦山二期的乏燃料损伤评价系统中。
[Abstract]:In this paper, a method for evaluating the degree of spent fuel damage in severe accidents with dose rate monitoring is introduced. the dose rate of the spent fuel with different enrichment and fuel consumption is calculated as a database, and the damage proportion of the fuel in the waste pool is evaluated according to the shutdown time, the occurrence time of the accident and the actual monitoring value, And the differential evaluation of the damage degree of different types of fuel in the spent pool is realized. The method has been applied to the evaluation system of the spent fuel in the second stage of Qinshan.
