1) delayed neutron precursor
缓发中子先驱核<能>
2) delayed neutron precursors
缓发中子先驱核
1.
Considering the fuel salt flow effect of the molten salt reactor,the neutron dynamic model was derived based on the particle conservation equations,and the critical problem was calculated by numerical method under three working conditions to study the flow effect to effective multiplication factor,fast neutron,thermal neutron and delayed neutron precursors distribution.
考虑新概念熔盐堆燃料盐的流动特性,从基本的粒子守恒方程出发,推导了熔盐堆的中子动力学模型,并采用数值方法对3种工况下熔盐堆的临界问题进行计算,考察流动对有效增殖系数、快中子分布、热中子分布及缓发中子先驱核分布的影响。
