压水堆堆芯损伤评价系统研究与开发

Abstract

Abstract: Core damage assessment is an important part of nuclear accident emergency assessment.Based on foreign literature and combined with domestic operation experience,core damage assessment of PWR is researched and the corresponding software system is developed.There are three methods for core damage assessment based on core uncovering time,online monitoring readings and sampling.Considering real-time demand of emergency,actual application of various power plants,and international experience,assessment based on online monitoring readings is adopted in this paper,which is mainly based on the core thermocouple readings and the containment radiation monitoring readings.

Key words: PWR, core damage, emergency assessment, core state
