Japan Atomic Energy Agency (JAEA) has been developing a reliable disassembly system for FBR fuel reprocessing as a part of FaCT. As For the disassembly system, laser type disassembly system had been developed, but it had some subjects as adhesion and fuel pin damage caused by dross. Then JAEA have proposed a new disassembly technology by mechanical disassembly system that consists of a mechanical cutting step and a wrapper tube pulling step. Mechanical cutting performance and pulling separation performance are confirmed by fundamental test, and Fundamental design of the mechanical disassembly system is established.
