Abstract

This study presents the development and benchmarking of a point detector in the OpenMC framework. The detector efficiently estimates neutron flux at a point, employing a relativistic formulation that is valid across all energy ranges. This is the first implementation of a point detector tally in OpenMC, validated through tests, that demonstrate excellent agreement with conventional methods. By enhancing simulation efficiency in challenging scenarios such as heavy shielding this work broadens OpenMC’s applicability to a wide range of geometries and nuclear physics reactions.

OpenMC中一个点检测器的开发和基准测试

本研究介绍了OpenMC框架中一个点检测器的开发和基准测试。该探测器采用一种适用于所有能量范围的相对论公式，有效地估计了一点上的中子通量。这是OpenMC中第一个点检测器计数的实现，通过测试验证，证明与传统方法非常一致。通过在具有挑战性的场景（如重屏蔽）中提高模拟效率，这项工作拓宽了OpenMC在各种几何形状和核物理反应中的适用性。

期刊介绍： Annals of Nuclear Energy provides an international medium for the communication of original research, ideas and developments in all areas of the field of nuclear energy science and technology. Its scope embraces nuclear fuel reserves, fuel cycles and cost, materials, processing, system and component technology (fission only), design and optimization, direct conversion of nuclear energy sources, environmental control, reactor physics, heat transfer and fluid dynamics, structural analysis, fuel management, future developments, nuclear fuel and safety, nuclear aerosol, neutron physics, computer technology (both software and hardware), risk assessment, radioactive waste disposal and reactor thermal hydraulics. Papers submitted to Annals need to demonstrate a clear link to nuclear power generation/nuclear engineering. Papers which deal with pure nuclear physics, pure health physics, imaging, or attenuation and shielding properties of concretes and various geological materials are not within the scope of the journal. Also, papers that deal with policy or economics are not within the scope of the journal.
