OSTI ID:6487878
Irradiated uranium aluminide fuel plates of 40% U-235 enrichment were heated for the determination of fission products released under flowing helium gas at temperatures up to and higher than the melting point of fuel-cladding material. The release of fission products from the fuel plate at temperature below 500/sup 0/C was found negligible. The firist rapid release of fission products was observed with the occurrence of blistering at 561 +- 1/sup 0/C on the plates. The next release at 585/sup 0/C might be caused by melting of the cladding material of 6061-Al alloy. The last release of fission product gases was occurred at the eutectic temperature of 640/sup 0/C of U-Al/sub x/. The released material was mostly xenon, but small amounts of iodine and cesium were observed.
