多功能栅格计算程序(SONG)是为适应新型反应堆的研发需求而开发的。在制作与之适应的多群数据库时,需要考虑新型反应堆在燃料、结构材料、冷却剂、慢化剂、能谱、燃耗深度方面的特性。应对新的需求,从燃耗链、能群结构、反应通道、共振参数等方面给出设计方案;利用经评定的核数据文件(ENDF)、核数据加工程序(NJOY)、核数据辅助加工程序(RUNBAT)、多群数据库管理程序(MANLIB),开展多群数据库的制作;针对该多群数据库进行了初步测试,结果表明数据库具备一定的可靠性。
The multi-purpose grid computing program (SONG) was developed to meet the research and development needs of new reactors. When creating a multi-group database that adapts to it, the characteristics of the new reactor in terms of fuels, structural materials, coolants, moderators, energy spectra, and burnup depth need to be considered. In order to meet the new demand, the design scheme is given from the aspects of fuel consumption chain, energy group structure, reaction channel, resonance parameters and so on. By using the approved nuclear data file (ENDF), nuclear data processing program (NJOY) (RUNBAT), multi-group database management program (MANLIB) to carry out the production of multi-group database; a preliminary test for the multi-group database, the results show that the database has a certain reliability.
