CEFR堆芯围桶开孔处温度场及流场分析

Analysis on Temperature Field and Flow Field of Reactor Core Barrel Openings for China Experiment Fast Reactor

摘要: 应用CFX对堆芯围桶开孔处温度场及流场进行模拟计算并对结果进行分析。利用模型Ⅰ、Ⅱ分别计算得到堆芯围桶开孔处的温度场及流场，并得到在正常工况下堆芯围桶开孔处钠的流动方向。计算验证了事故余热排出系统（CAPX）水台架的试验结果，为CEFR堆芯围桶开孔的安全分析打下基础。

Abstract: The paper gives analysis of the temperature and flow field around openings by software CFX, and figures out the flow direction around openings under CEFR normal condition. The calculation result is consistent with the test result of CAPX (the test-bed of decay heat removal system) and ground for the safety analysis later.
