Summary
Analyses of integral power-to-melt tests, HELD P-19 and P-20, are presented. These tests contained mixed-oxide, UO/sub 2/-PuO/sub 2/, fuel prototypic of fuel to be used in the driver fuel assemblies of the Fast Flux Test Facility, FFTF, which could be used in initial Fast Breeder Reactors, FBR's. The experiments were irradiated in the Experimental Breeder Reactor No. 2, EBR-II, for the Hanford Engineering Development Laboratory, HELD. The primary test variables are fabricated fuel-to-cladding gap size and accumulated fuel burnup to 1.1 at.%. The observed improved thermal performance at higher burnup is analyzed based on results and conclusions drawn from sibling pins irradiated during the preconditioning phases of the P-20 test. These pins were not included in the overpower phase of the P-20 test. The primary cause of the improved thermal performance was found to be maturing fuel restructuring and rapid fuel-to-cladding gap closure. The favorable impact of these observations on the design and operation of FFTF and future FBR's is also reviewed.
