Plutonium Recycle Burnup Data and Results From the Batch Core Experiment.

Abstract

As a result of the Batch Core Experiment which was conducted in the Plutonium Recycle Test Reactor, a large amount of burnup data and gammaray data was made available for analysis. The data represented plutonium recycle fuel in that the fuel composition was initially U0 2 -2 wt% Pu0 2 .A maximum burnup of 9485 MWD/MTM was determined from the fuel samples The gamma-ray data were analyzed to determine power distributions and effects of fission product migration. The results indicated localized regions of fission product concentrations due to the migrations of 106Ru _ 106 Rh , 134 Cs and 137 Cs .• . .
