Abstract The remote injection casting process was developed using a high-capacity casting system in a mockup facility to secure the key technology for the fabrication of transmutation metallic fuels in hot cells. Seventy-eight fuel slugs fabricated simultaneously through remote injection casting were confirmed to satisfy the fabrication specification. The reaction characteristics of the coating candidates for the reusable crucible were investigated by using sessile drop tests with U-10wt%Zr-5wt%RE at 1450 °C for 1 h and LaYO3 showed the smallest interaction width. The improvement in the adhesion of Y2O3 coatings on the inner walls of the quartz mold was effective in reducing the reaction between the melt and the mold. The mechanical and chemical cleaning processes were investigated to remove the surface contamination layer of the melt residue for recycling. Both cleaning methods were effective with the mechanical treatment favored owing to the operations in hot cells. The remote injection casting process equipped with fuel loss control components developed in this work will fabricate transmutation fuels in hot cells.

用于制造金属燃料的减少材料损失的远程注射铸造工艺

摘要 远程注射铸造工艺是在模型设施中使用高容量铸造系统开发的，以确保在热室中制造嬗变金属燃料的关键技术。通过远程注射铸造同时制造的 78 个燃料段塞被确认满足制造规范。通过使用 U-10wt%Zr-5wt%RE 在 1450 °C 下静置跌落试验研究可重复使用坩埚涂层候选物的反应特性，1 小时，LaYO3 显示出最小的相互作用宽度。石英模具内壁上 Y2O3 涂层附着力的改善可有效减少熔体与模具之间的反应。研究了机械和化学清洁过程，以去除熔体残留物的表面污染层以进行回收。由于在热室中操作，这两种清洁方法都对机械处理有效。配备在这项工作中开发的燃料损失控制组件的远程喷射铸造工艺将在热电池中制造嬗变燃料。
