From previous reports, the powdered fuel was considered to be suitable for the preparation of high concentrated solution efficiently. And the short stroke shearing technology is expected to make the powdered fuel rationally. In this study, the short stroke shearing tests with simulated fuel pin bundle has been carried out at engineering scale. From these tests, fundamental data of the short stroke shearing characteristics were obtained.

In order to develop future FBR nuclear fuel disassembling technology, and in order to acquire the fundamental laser cutting knowledge, various laser cutting experiments have been done. In comparison with the present technology, it has been concluded that the laser cutting could be applied to chop the nuclear fuel assembly components finely.

JAEA have been developing a reliable fuel disassembly and shearing systems in cooperation with Japan Atomic Power Company (JAPC). We proposed a disassembly system utilizing mechanical cutting and pulling method. We designed and fabricated an engineering-scale test device, and confirming the system performance by using the simulated fuel assembly. And we proposed new shearing procedure as short-stroke cutting to provide highly fragmented fuel to realize efficient fuel dissolution required from the uranium crystallization process. We designed and fabricated the fuel transfer device and carried out some experiment to confirm that the fuel fragmentation rate and shared stroke was chosen to be 1 cm. In this paper, we will report the latest experiment for these systems.
