摘要
子通道分析软件CORTH可以分析一系列子通道在稳态和瞬态工况下的单相流动和两相流动,能够在反应堆热工水力与安全分析领域发挥重要应用。工程设计软件计算结果的可信度很重要,因此需要对CORTH软件进行充分验证与确认。本文介绍了CORTH软件的验证与确认方法,给出了验证与确认的法规要求和关键步骤。核电厂堆芯出口温度分布验证计算结果表明CORTH软件的计算精度较高,能够满足工程设计与分析需求。
CORTH is a subchannel code, which is applicable to analysis of single-phase flow and two-phase flow under steady or unsteady condition inside subchannels, and it can play an important role in reactor thermal hydraulic and safety analysis. The reliability of analysis code is very important, so it is necessary to validate and CORTH. The method of CORTH verification and validation is introduced, then the verification and validation regulatory requirement and key steps are introduced. The nuclear power plant core outlet temperature validation result show the good accuracy of CORTH that meets the requirement of engineering design and analysis.
