FFTF reload core nuclear design for increased experimental capability

Conference ·
OSTI ID:7339412

In anticipation of continued growth in the FTR experimental irradiations program, the enrichments for the next batches of reload driver fuel to be manufactured have been increased to provide a substantially enlarged experimental reactivity allowance. The enrichments for these fuel assemblies, termed ''Cores 3 and 4,'' were selected to meet the following objectives and constraints: (1) maintain a reactor power capability of 400 MW (based on an evaluation of driver fuel centerline melting probability at 15 percent overpower); (2) provide a peak neutron flux of nominally 7 x 10/sup 15/ n/cm/sup 2/-sec, with a minimum acceptable value of 95 percent of this (i.e., 6.65 x 10/sup 15/ n/cm/sup 2/-sec); and (3) provide the maximum experimental reactivity allowance that is consistent with the above constraints.
