The Hot Fuel Examination Facility (HFEF) was assigned the remote disassembly and examination of the Fuel Element Failure Propagation (FEFP) loops. These loops, containing bundles of fast-reactor fuel elements, will be irradiated in the Engineering Test Reactor to obtain information on failure propagation in this type of fuel. A detailed preliminary plan and procedure h?ve been developed by the HFEF staff for handling, disassembling, and examining the irradiated loops. The concepts developed meet the functional criteria established by the FEFP Project in the System Design Description. The disassembly and examination will be performed in the HFEF/N main cell, which is large enough to accommodate a loop in the vertical position. The equipment to be added to HFEF/N for the handling of the FEFP loop will include a loop-insertion cell, support structures for the loop and test train, a tube heater, several cutting machines, and many disassembly and examination fixtures.
