摘要
适用于连续能量蒙特卡罗程序的敏感性分析方法是当前的研究热点。本文建立了5种不同反应类型的敏感性系数的计算公式,对当前应用广泛的反复裂变几率法的理论基础及算法进行了分析。分别使用RMC程序和MCNP6程序计算了keff对核数据的敏感性系数,计算结果吻合良好。本文结果表明RMC程序初步具备了敏感性分析的功能。
Methods suitable for sensitivity analysis in continuous-energy Monte Carlo codes become a research hotspot in the field of reactor physics.In this work,the formulas of sensitivity coefficients of five different reaction types were established.Then,the theoretical basis and the algorithm of the iterated fission probability method which was used widely currently were discussed.Furthermore,two Monte Carlo codes,RMC and MCNP6,were used to compute eigenvalue sensitivity coefficients to nuclear data.The agreement between RMC and MCNP6 is well.The results indicate that RMC is capable to perform sensitivity analysis preliminarily.
