摘　　要：利用经济发展与合作组织核能机构(OECD/NEA)压水堆堆芯弹棒瞬态基准题对RELAP5-TDNK进行了验证。使用RELAP5-TDNK建立了弹棒基准题模型,分析了两种弹棒问题,对程序的数据交换能力、耦合方法和瞬态事故分析能力进行了检验。与国际上多种程序进行比较,结果表明:RELAP5-TDNK程序模拟结果较好,能够分析事故或瞬态过程中堆芯内局部功率和热工参数的相互作用,具有分析强反馈现象的能力。In order to verify and validate the coupled RELAP5-TDNK code,analysis of the rod ejection accident framed by OECD/NEA was conducted.Three dimensions neutronics model is introduced to RELAP5 in RELAP5-TDNK which advances the ability to analyze the transients with strong feedback phenomenon.The models of the rod ejection are established and two problems are processed.Compared to other coupled codes,RELAP5-TDNK gets a good accuracy and has the ability to analyze the transients with strong feedback phenomenon.
