This paper presents a remote testbed for metallic fuel fabrication using surrogates or depleted uranium. The testbed named “remote fuel fabrication mock-up (RFFM)” was created at the Korea Atomic Energy Research Institute and specifically designed to incorporate remote operation and maintenance. The subsystems of the RFFM are described, and test results regarding remotely conducted metallic fuel slug fabrication at the RFFM are also presented. After fabricating fuel slugs using copper ingots, their specifications and properties were analyzed and evaluated using chemical analysis, radiographic tests, and diameter and weight measurements. Analysis results showed that the fabricated metallic fuel slugs have an acceptance rate of more than 90% and a casting ratio (ratio of weight of injected metal to charged metal) of more than 0.7. Moreover, operations involving remote handling of in-cell equipment were also satisfactory.

KAERI的远程燃料制造模型中的金属燃料制造工艺开发

本文介绍了使用替代物或贫铀制造金属燃料的远程测试平台。被称为“远程燃料制造模型（RFFM）”的测试平台是由韩国原子能研究院创建的，专门用于远程操作和维护。描述了RFFM的子系统，并提供了有关RFFM上远程制造金属燃料块的测试结果。使用铜锭制造燃料块后，使用化学分析，射线照相测试以及直径和重量测量对它们的规格和性能进行分析和评估。分析结果表明，所制造的金属燃料块的合格率大于90％，铸造比（注入金属与填充金属的重量比）大于0.7。此外，
