Abstract

A number of fast reactor projects suggest using neptunium nitride (NpN) as a fuel. Given that the neutron-physical characteristics of Np-237 are insufficiently studied, a detailed analysis of the libraries of evaluated nuclear data is necessary for numerical modeling of the reactor operation. The purpose of this study is to compare libraries to reduce the errors in calculating the critical mass of Np-237. The experimental values of K-eff (found in the experiment conducted at Los Alamos National Laboratory in 2002) are compared with the calculated values obtained using various software packages (MCNP, Serpent) and 14 libraries of evaluated nuclear data (JEFF, ENDF, JENDL, TENDEL, ROSFOND).

以 Np-237 球临界值计算为例分析已评估核数据库

摘要一些快堆项目建议使用氮化镎（NpN）作为燃料。鉴于对 Np-237 的中子物理特性研究不足，有必要对已评估核数据的库进行详细分析，以便对反应堆运行进行数值建模。本研究的目的是比较各种库，以减少计算 Np-237 临界质量时的误差。将 K-eff 的实验值（2002 年在洛斯阿拉莫斯国家实验室进行的实验中发现）与使用各种软件包（MCNP、Serpent）和 14 个核数据评估库（JEFF、ENDF、JENDL、TENDEL、ROSFOND）计算得出的值进行了比较。
