摘要

核热推进系统是开启太阳系星际旅行的技术之一，目前对精确模拟此类系统的需求与日俱增。本文研究了 KIWI-B-4E 反应堆，它是 NERVA 计划的第一个原型，于 1964 年实现了全功率重启。为了模拟该反应堆，我们建议使用 OpenMC Monte Carlo 代码和 GeN-Foam 多物理场代码来模拟全堆芯中子电子学和热水力学。尽管关键设计参数的不确定性导致无法进行详细的中子验证，但大部分结果显示与现有实验数据非常吻合。

Full core study of the KIWI-B-4E Nuclear Thermal Propulsion system using OpenMC and GeN-Foam

Nuclear Thermal Propulsion systems are one of the technologies to unlock interplanetary travel in the solar system and there is currently an increasing demand for accurately simulating such systems. The present paper investigates the KIWI-B-4E reactor, the first prototype of the NERVA program that achieved a restart at full power in 1964. To simulate this reactor, we propose the use of the OpenMC Monte Carlo code and the GeN-Foam multi-physics code to model full-core neutronics and thermal-hydraulics. The results mostly show a good agreement with the available experimental data, although uncertainties on key design parameters do not allow for a detailed neutronics validation.
