采用OMEGA非均匀加热棒束热端破口实验数据对CATHARE2 V1.5qR6程序的校核

Qualification of CAHARE2 V1.5qR6 Using OMEGA Rod Bundle Hot- Leg Break Experimental Data

采用 OMEGA非均匀电加热棒束热端破口喷放试验数据对 CATHARE2 V1.5版本程序基本物理关系式模块的性能进行校核，检验基本物理关系式模块升级后系统程序的综合性能。从总的计算结果来看，新版程序对 OMEGA非均匀加热棒束热端破口试验的热工水力的计算比较合理，特别是对 CHF以及其前区的热工水力的计算十分可靠。由于基本物理关系式模块在升级过程中所做的模型修改与该项实验所涉及的基本物理现象关系较小，故基本物理关系式模块升级版 Revision6和次新版本 Revision5的计算结果基本一致。

Qualification of CATHARE2 V1.5qR6 using the hot- leg break experimental data got from OMEGA rod bundle tests has been presented in this paper.The calculated results show that the predicted results of V1.5qR6 on the hot- leg break tests in OMEGA rod bundle tests are reasonable,especially the calculation of thermal- hydraulics character of CHF and pre- CHF is very correct.The calculated results of Revision6 has a good agreement with that of Revision5.
