摘要/Abstract

摘要： 本文针对M310反应堆建立了大破口失水事故(LBLOCA)始发应急工况进程预测方法。根据事故特点将复杂的一回路进行合理简化,对质量守恒与能量守恒方程进行近似求解,使用经典公式预测应急工况进程。将堆芯活性区划分成4个径向环和10个轴向层,即40个栅元。使用实验关联式计算堆芯换热,得到包壳温度,然后根据包壳温度判断堆芯工况。基于本文建立的方法,可以开发大破口始发应急工况进程预测程序。

关键词: M310, 应急工况, 进程预测, 大破口失水事故(LBLOCA)

Abstract: Method for prognosis of severe accident response progress initiated by large break loss of coolant (LBLOCA) was established,based on transient analysis for M310 reactor.The primary loop is rationally simplified based on characters of LBLOCA.The mass and energy conservation equations were solved approximately and the classical formula were used to prognose emergency condition progression.The active core area was divided into 4 radial rings and 10 axial levels,i.e.40 cells.Experimental correlations were used to calculate heat transfer in the core and the cladding temperature was obtained.Then the core condition can be judged according to the cladding temperature.A code for prognosis of LBLOCA initiated emergency condition could be developed based on the method established in the paper.

Key words: M310, emergency condition, progress prognosis, LBLOCA
