金属燃料リサイクルプラント(38tHM/年)の燃料製造設備について、これまでの設計研究及び品質管理概念をベースに、主要機器の概念設計を進めた。あわせて、製品のハンドリング装置の概念設計も行い、製品等のハンドリング時間を検討するとともに、燃料成分調整手法を考慮して、燃料製造設備の機器台数を最適化した。(1)代表的な主工程設備及び燃料ハンドリング・秤量設備の構造概念設計燃料成分調整装置、燃料ピン組立装置、Naボンディング装置、燃料スラグパレットハンドリング装置、燃料ピンパレットハンドリング装置、燃料ピンハンドリング装置及び秤量器の構造概念設計を実施した。(2)ハンドリング時間を考慮した必要設備台数の見直し上述の概念設計結果を基に、燃料スラグ及び燃料ピンをハンドリングするための所要時間を見積り、機器の処理時間に対応するよう、燃料製造設備の機器台数を最適化した。(3)設備間バッファの検討機器相互の処理能力を比較するとともに、製品のハンドリング時間を考慮して、設備間バッファ量を検討した。あわせて、被覆管等の部材のバッファ量も検討し、燃料製造設備内の保管棚等のバッファ量を最適化した。

In this research work for the metal fuel fabrication system (38tHM/y), the studies of the concept of the main process equipments were performed based on the previous studies on the process design and the quality control system design. In this study the handling equipment of the products were also designed, according to these designs the handling periods were evaluated. Consequently the numbers of the equipments were assessed taking into account for the method of the blending the fuel composition.(1)Structural concept design of the major equipments, the fuel handling machine and the gravimetries in the main fabrication process The structural concept were designed for the fuel composition blending equipment, the fuel pin assembling equipment, the sodium bonding equipment, the handling equipment for fuel slug palettes, the handling equipment for fuel pins and the gravimetries.(2)Re-assessment of the numbers of the equipments taking account of the handling periods Based on the results of item (1) the periods were evaluated for the fuel slug and pin handling. Accordingly the numbers of the equipments were optimized.(3)Design of the buffer storages The buffer storages among the equipments were designed through the comparison of the process speed between the equipments taking into account for the handling periods. The required amount of the structural parts (for example cladding materials) was assessed for the buffer in the same manner and the amount of the buffer facilities were optimized.
