反应堆蒙特卡罗程序CosMC验证策略初步研究

Preliminary Study on Strategy of Verification of Reactor Monte Carlo Code CosMC

软件验证和确认(V&V)对保证软件质量具有重要意义,合理高效的V&V策略可以事半功倍。本文提出了用于反应堆堆芯计算分析的三维蒙特卡罗粒子输运程序(Cos MC)的验证和确认的现象定义级别排序技术(PIRT)表,采用国际上著名的临界基准实验和C5G7基准题Cos MC的临界计算功能及中子注量率计算的准确性进行了验证。验证结果表明:Cos MC用于临界计算是可靠的;C5G7基准题的计算结果与MCNP的计算结果吻合很好。

Software verification and validation is of great significance to ensure the software quality, reasonable and efficient. Verification and validation strategy is the key point of the verification and validation process. In this study, we proposed the PIRT table of the verification and validation for Cos MC. The reactor critical computing functions and the accuracy of the neutron flux calculated by Cos MC were verified by using of well-known international critical C5G7 benchmark. The results agreed well with the results calculated by MCNP.
