Abstract
为验证经二次开发后的RELAP5程序在倾斜条件下的适用性,基于缩小比例的反应堆二次侧非能动余热排出系统(Passive Residual Heat Removal System,PRS)实验装置,开展了倾斜角度为-24°~+24°的工况下的余热排出实验。在此基础上,使用二次开发后的RELAP5程序对实验工况进行了模拟计算,利用实验数据验证其适用性,并进行了进一步对比分析。研究结果表明:二次开发后的RELAP5程序能有效预测倾斜条件下系统运行特性的变化;倾斜条件下C型换热器内冷凝段长度将发生变化进而影响换热效果,当倾斜角度为正时,倾斜角度越大系统整体换热效果越好。本文研究结果可为海洋条件下二次侧非能动余热排出系统的设计提供一定参考
