共计包含5个程序的热中子反应堆物理设计程序系列已初步建立。所选择的国外程序有WIMS/D4、CITATION和NGFM,这三个程序均具有精度高、速度快、使用灵活的特点。我们编制的程序有BTM和RATC。这些程序的主要功能简介如下:(1)WIMS/D4程序单棒或束棒少群常数及燃耗计算程序,可产生堆芯各构件的少群或宽群常数。 A total of five programs including thermal physics reactor design series has been initially established. The selected foreign programs WIMS / D4, CITATION and NGFM, these three programs are high precision, fast, flexible use of features. We have compiled programs BTM and RATC. The main functions of these programs are briefly described as follows: (1) WIMS / D4 program Single rod or bundle of rods Small group constant and burnup calculation program can produce a small group or wide group constants of each component of the core.
