GASFLOW应用于HTR-PM冷却剂排放事故分析

摘要

模块式高温气冷堆（H T R‐PM ）在冷却剂排放事故下的舱室承压能力是反应堆安全分析的重要对象。通过对FLUENT、GASFLOW和RELAP5的计算结果进行对比分析，发现GASFLOW因其兼顾计算效率与计算结果合理性的特性，最适合反应堆舱室在冷却剂排放事故下的承压计算。%The validity of the reactor cabinet pressure loading capacity of HTR‐PM fol‐lowing a loss‐of‐coolant accident (LOCA ) stands as the main object for reactor safety analysis . By comparing the computation results of FLUENT , GASFLOW and RELAP5 ,it is found that GASFLOW acts as the most suitable software for analyzing pressure loading capacity under LOCA with coolant discharging into reactor cabinet , because of its special features w hich balance between computation efficiency and reliability .
