反照蒙特卡罗方法和MORSE-ALBC程序

Albedo Monte Carlo Method and MORSE-ALBC Code

为解决大型空腔内的辐射散射及大尺寸孔缝的辐射泄漏问题,开展了反照蒙特卡罗方法研究。在引进开发基础上,经过改进,功能扩充,形成了具有反照功能的蒙特卡罗程序MORSE-ALBC。以它为主体,建立了辐射泄漏计算程序系统,并运用该系统进行了反应堆压力容器绝热层缝中子泄漏计算研究。

In order to resolve the problem of radiation scatter and streaming in large size void and gap, we studied Albedo Monte Carlo method (AMC). By means of introducing, revising and enhancing function of MORSE-CG and BREESE codes, the MORSE-ALBE code was formed.Based on the code, the code system for streaming calculation was constituted and was used for calculating neutron streaming through the thermal insulator annular gap of actual reactor pressure vessel.
