Abstract:

In order to generate a multi-group constant library NuDa-SN for the 3D discrete ordinate (SN) transport program JSNT-S developed in CAEP Software Center for High Performance Numerical Simulation, a basic line of master library cooperating with work library was put forward. Based on the ENDF/B-Ⅶ.1, a master library was generated with NJOY2016 and CMiler codes. 455 nuclides are included in this master library which collapsed into 199 neutron energy groups and 42 photon energy groups. In order to verify the reliability of this master library, unit test, criticality benchmark test and shield benchmark test were carried out respectively. All the tests show that this master library can be used reliably in the criticality calculation and shielding calculation.

Key words: NuDa-SN, multi-group constant library, master library, benchmark test

摘要:

为给中物院高性能数值模拟软件中心自主研发的三维离散纵标(SN)输运软件JSNT-S制作配套的多群常数库NuDa-SN,制定了主库与工作库配合的基本路线。其中,主库采用NJOY2016与CMiler程序基于ENDF/B-Ⅶ.1评价数据库制作。主库包含455个核素,中子能群数为199,光子能群数为42。为验证主库的可靠性,分别对主库进行了单核素测试、临界基准检验以及屏蔽基准检验,所有测试表明主库在临界计算和屏蔽计算方面具有相当的可靠性。
