摘要: 用多群Sn方法(离散纵标法)独立编制了α本征值计算程序,在一定程度上解决了次临界情形下α本征值计算遇到的困难,并对含空腔系统给出了一个简化处理模型.对标准问题的计算表明,该程序算法可靠,计算结果可信.

关键词: α本征值, 输运方程, 次临界系统, 离散纵标

Abstract: A code is developed to compute the α eigenvalue by the multigroup discrete ordinate method.It can overcome the difficulty of α eigenvalue calculation below criticality to a considerable extent.A processing technique is also devised to apply to the system with a cavity at the center.The calculation results are believable and the algorithm is reliable.

Key words: α eigenvalue, transport equation, subcritical system, discrete ordinates
