[en] The fuel disassembly station in the Interim Examination and Maintenance Cell, at the Fast Flux Test Facility in Richland, Washington, utilizes both horizontal and vertical duct cutting equipment that is remotely controlled by a computer. Operator friendly computer software and feedback control have contributed to successful duct cutting and removal from highly irradiated fuel assemblies even where significant duct dilation has occurred. This finely controlled system with safeguard features has been utilized to successfully disassemble several fuel assemblies. Subsequent fuel pin examinations have verified the expected material and fuel performance and provide the basis for extending the fuel lifetime
