摘要: 本文对由长方形或三角形栅元组成的反应堆栅格,从碰撞概率定义出发,建立了二维多体系统的中子首次碰撞概率计算的公式,并将计算结果与蒙特卡洛方法的计算结果进行了比较。

Abstract: In this paper the formulae of the collision probobilities for the isotro-pic two-dimensional neutron transport problem on the mixed region consisting of rectangular or triangle cells are given. Based on these formulae the code has been developed and applied to tow-dimensional mixed cells calculations. The calculated results show good agreement with those of Montecalo method and conservation principles.
