摘要
为确保某反应堆废气罐破裂事故分析的放射性释放后果满足限值要求,在废气罐所在房间通风关闭的情况下,本文基于某反应堆衰变热曲线的室内热源以及相关的设计参数条件,对房间墙体温度的影响进行分析。经分析,在衰变热长期作用下,墙体温度最大值为44.7℃,不会超过混凝土长期运行时温度为65℃的限值要求,为废气罐放射性释放事故分析提供参考。
In order to avoid the consequences of radioactive release accidents caused by excessive source term exceeding the limit requirements,this article analyzes the influence of room wall temperature based on the indoor heat source of a certain reactor decay heat curve and related design parameter conditions,with the ventilation of the room where the waste gas tank is located closed.After analysis,under the long-term action of decay heat,the maximum temperature of the wall is 44.7℃,which will not exceed the limit requirement of 65℃for the long-term operation of concrete.This provides a reference for the analysis of radioactive release accidents in waste gas tanks.
