This paper describes a fuel pin removal device used for pin removal from irradiated fuel assemblies at the Fast Flux Test Facility (FFTF). After irradiation in the FFTF, selected fuel assemblies are remotely disassembled in the Interim Examination and Maintenance (IEM) cell. The remote disassembly, following sodium removal, consists of slitting and removing the duct and then removing the fuel pins one-at-a-time by sliding the pins from parallel attachment rails. All pins are removed from one rail before starting on the next. The new pin removal equipment has been used very successfully on the last three fuel experiments disassembled in the IEM cell, including one assembly containing residual sodium. Pin removal time has been cut in half, and this once tedious and time-consuming activity has been turned into an almost effortless evolution.
