AI 中文总结

本文通过智能体移植Njoy和OpenMC至Rust,在Outram Park中构建ENDF到蒙特卡罗流水线,验证U-238截面及ICSBEP基准,推动其向多物理模拟工具包发展。

AI 中文摘要

在Outram Park中,通过智能体驱动的Rust移植,实现了Njoy和OpenMC的移植,从而构建了从ENDF到蒙特卡罗模拟的便捷流水线。该代码仍为原型,未来需进行更广泛的验证与确认研究。本文展示了U-238的多普勒展宽截面,并与OpenMC预生成的HDF5文件进行了比较。此外,还使用ICSBEP基准以及作者博士论文中采用的含TRISO燃料的FHR Pebble,对OpenMC的蒙特卡罗移植进行了初步测试。核数据与蒙特卡罗案例研究的加入,使Outram Park的重点从多相模拟工具包转向多物理模拟工具包。

英文摘要

An agentic Rust port of both Njoy and OpenMC components was attempted to produce a convenient ENDF to Monte Carlo simulation pipeline in Outram Park. The code is still a prototype with more extensive verification and validation studies required in future studies. For initial verification work, Doppler-broadened cross sections of U-238 are demonstrated in this paper and compared to OpenMC pre-generated HDF5 files. Additionally, initial testing of the Monte Carlo ports from OpenMC were also performed with ICSBEP benchmarks and a FHR Pebble with TRISO Fuel used in the author's PhD dissertation. The addition of nuclear data and Monte Carlo case studies shifts the focus of Outram Park from a Multi-Phase simulation kit to a Multi-Physics simulation kit.
