MCNP3B程序是一个大型的多功能蒙特卡罗程序,可用于屏蔽设计和应用孔道的设计,以及某些临界装置的设计计算。文章介绍了应用MCNP3B程序对DF堆次临界装置的几个实验布置进行的物理参数计算,并将计算结果与实验结果进行了比较。通过对DF次临界装置的研究,以求MCNP3B程序能为零功率实验提供指导性意见,保证零功率实验的安全。
The MCNP3B program is a large, versatile Monte Carlo program designed for shielding design and application of holes, as well as design calculations for some critical devices. The paper introduces the calculation of the physical parameters of several experimental arrangements of the DF stack subcritical device by MCNP3B program, and compares the calculated results with the experimental results. Through the research of DF subcritical device, MCNP3B program can provide guidance for zero-power experiment and guarantee the safety of zero-power experiment.
