Onuki, Norihiko*; not registered

In this study,for the feasibility studies on commercialized FBR cycle system, we researched the vibration packing fuel fabrication system and main fuel fabrication equipments for wet fuel recycle plant. The fuel fabrication system has fuel pin fabrication process, fuel pin inspection process, fuel assembly fabrication process and fuel assembly inspection process. Main equipments of fuel fabrication sysutem are pin magazine rack to hold the fuel pins at vibration packing, vibration packing equipment, spacer insertion equipment, upper end plug welding equipment, fuel density measurement equipment, fuel assembly fabrication equipment and fuel assembly inspection equipment. We investigated the basic designs, operation procedures, material handlings, operating flow charts,maintenances and failure rate of those equipments. Furthermore, criticality, fire/explosion and earthquake-proof were investigated as safety analysis, and the manners of quality controls and material accountancy of the fuels were investigated. Economical evaluation and generated wastes evaluation were carried out for the above fuel fabrication systems, too.
