Abstract:

In order to satisfy the needs of Monte Carlo transport calculation for high energy nuclear device such as ADS, the processing method and code of high energy evaluated nuclear data based on Ruler coupled with NJOY system were established by improving relevant processing module. Based on the high energy evaluated nuclear data library JENDL-HE-2007, the application library with ACE format was developed using the method and code. Through a series of plotting and simple Monte Carlo transport simulations, the ACE library was verified and validated, and the result shows that it can be used to do Monte Carlo transport calculation. It is proved that the method of coupling Ruler with NJOY’s module can be used for processing high energy evaluated nuclear data.

Key words: evaluated nuclear data, nuclear data processing, ADS, transport calculation, Ruler

摘要：

为满足加速器驱动次临界系统ADS等高能核装置的蒙特卡罗输运计算需求，通过对相关核数据处理模块的改进，建立了一套基于我国自主的群常数制作软件Ruler与国际公认的核数据处理系统NJOY耦合的中高能评价核数据处理方法及程序系统。通过该方法基于日本高能评价核数据库JENDL-HE-2007制作了ACE格式连续点截面库，并通过一系列绘图及简单问题的蒙特卡罗输运计算，验证了该库是完整的、合理的，可用于蒙特卡罗输运计算，证明了Ruler与NJOY功能模块耦合的方法可用于高能评价核数据的处理。
