| 摘 要： | 堆芯损伤评价是反应堆事故后应急评价的重要组成部分。本文在国外文献基础上,结合国内的运行经验,对压水堆堆芯损伤评价进行研究,并开发了相应的软件程序。堆芯损伤评价包括基于堆芯裸露时间、在线监测仪表读数和取样分析数据三种方法。考虑应急实时要求、电厂实际情况与国际经验,本文采用了基于在线监测仪表读数的评价方法,该方法主要是基于堆芯热电偶读数与安全壳辐射监测仪表读数进行评价,其他监测仪表读数进行辅助合理性证实。

| 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. |
