Abstract

Nuclear energy is one of the promising ways of reaching carbon neutrality, but this goal requires the development of new reactor types. One such concept is the molten salt reactor system, which uses chlorine-based fuel salts. Developing this system needs reliable neutronic data for all materials used, with particular emphasis on core components. While uranium cross-sections remain well-studied, sufficient experimental data for chlorine is lacking, particularly for validations of current data evaluations. This paper presents new, precise integral experiments to validate various chlorine cross-section evaluations. Notably, compared with experimental results, the currently available data sets exhibit significant discrepancies, suggesting that simulations based on current nuclear data evaluations may be unreliable.
LR-0 基准场中氯的中子传输验证
核能是实现碳中和的有希望的途径之一,但这一目标需要开发新型反应堆。其中一个概念是熔盐反应堆系统,它使用氯基燃料盐。开发该系统需要所有所用材料的可靠中子数据,特别强调核心部件。虽然对铀的截面仍有充分的研究,但缺乏足够的氯的实验数据,特别是用于验证当前数据评价的数据。本文提出了新的、精确的积分实验来验证各种氯横截面计算。值得注意的是,与实验结果相比,目前可获得的数据集显示出显著差异,这表明基于当前核数据评估的模拟可能不可靠。

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.
