摘要
本文的主要内容是在中国先进研究堆(CARR)堆内固进行态氚增殖剂陶瓷球床辐照实验的物理计算。本文采用Monte Carlo粒子输运模拟程序MCNP5对陶瓷球床进行堆内建模计算得到不同功率下球床的中子注量率、发热功率和产氚速率。通过更改氚增殖剂球床组件的结构尺寸或堆功率来满足实验的要求,得到满足实验要求的球床结构,在堆内辐照陶瓷球床组件进行物理计算和分析,从而为热工计算分析提供数据,为整体装置在堆内辐照实验提供安全分析。最终得到球床的中子注量率为5.63x10^(12)n/cm^2s,球床的发热功率为491.9W。
The main content of this paper is in-pile irradiation experiment of International Thermonuclear Fusion Reactor Experiment(ITER)tritium breeder blanket module(TBM)have been carried out in China Advanced Research Reactor(CARR).This paper adopts the Monte Carlo particle transport MCNP5simulation program to modeling the pebble bed.By using the statistical pebble-bed neutron flux,counting card energy deposition and yield,get the pebble bed under different power of neutron flux rate,heating power and the tritium production rateis introduced into reactor.In order to ensure the safety of the reactor and ceramic pebble beds assembly,and to meet requirements of the experiment,it can be realized by changing the structure size of pebble beds or the power of reactor,in pile irradiation breeder pebble bed assembly physical calculation and analysis,so as to provide data for the thermodynamic calculation and analysis,the pile irradiation experiments provide safety analysis as a whole install.Finally the physics showed neutron flux of the pebble beds is5.63x1012n/cm2s,heating power is491.9W.
