Release of fission products from irradiated SRP fuels at elevated temperature. Data report on the first stage of the SRP source term study
1987
For a sound evaluation of the consequences of a hypothetical nuclear reactor accident, a knowledge of the extent of fission product release from the fuel at anticipated temperatures and atmosphere conditions is required. Measurements of fission product release have been performed with a variety of nuclear fuels under various conditions of temperature and atmosphere. While the use of data obtained on fuels similar to the fuel of interest may provide a reasonable estimate of release fractions, precise information of this nature can only be obtained from measurements employing specimens of the actual fuels used in the nuclear reactor under consideration. The two fuels of interest in the present study are an alloy, a dispersion of UAl/sub 4/ in an aluminum matrix, and a cermet, a dispersion of U/sub 3/O/sub 8/ in an aluminum matrix. Both fuels are clad in aluminum.
