Post Irradiation Examination of FFTF Irradiated MFF-3 and MFF-5 Fuel Pins

摘要

The MFF series of metal fuel irradiations [1]rnconducted in the Fast Flux Test Facility (FFTF) providesrnan important potential comparison between data generatedrnin the Experimental Breeder Reactor (EBR-II) reactor andrnthat expected in a larger scale fast reactor. The FFTF withrna 36-inch tall fuel column and a cosine neutron fluxrnprofile resulted in a core with peak cladding temperaturernat the top of the fuel column but the peak burnup at therncenterline of the core.
