Abstract

The design space for a molten chloride salt fast reactor utilizing the NaCl-UCl₃ salt in breeding and burning mode was investigated employing a neutron balance method for mixed liquid fuels with varying molar UCl₃ concentrations. An infinite one-cell core was adopted as the physical model to calculate static neutrons based on critical search methodology and to perform burn-up calculations concerning the evolution of neutron balance. The results indicate that the NaCl-UCl₃ system demonstrates favorable breeding characteristics and possesses exceptional inherent core safety. Furthermore, the minimum burnup requirement is intricately associated with UCl₃ molar concentrations; an increase in molar content results in a more rapid attainment of the neutron balance state and a reduction in the minimum burnup requirement. Additionally, considering the neutron loss term, an increase in UCl₃ molar contents from 0.30 to 0.50 correlates with an enhancement in the maximum tolerable neutron loss term, rising from 6.263% to 13.145%.

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.
