| 摘 要： | 针对控制棒大距离移动时积分价值计算有较大误差的问题,分析发现船用反应堆围板/反射层节块的等效均匀化参数尤其是不连续因子受反应堆内控制棒的分布状态影响是导致误差的主要原因,通过引入二维围板/反射层等效均匀化参数计算方法详细计算不同棒态下围板/反射层的均匀化参数,最后经验算发现,能够使积分价值计算误差控制在2%以内。

| Abstract: | Aimed at the problem of inaccurate calculation in integral worth of the outboard control rod,this paper introduces the theory of equivalence and calculates the factor to reflecting layer.It also analyzes the non-uniformity of outer components and reflecting layer in marine incore＇s and finds that discontinuity factor is caused by distribution of control rods in ship reactor.Using transmission probability method and the nonlinear iterative semi-analytical nodal method,the problem is solved and the error of integral worth of control rod assembly is controlled in 2%. |
