Comparison of spent fuel decay heat rate ORIGEN2 prediction and calorimeter measurements
Conference

OSTI ID:5714040
Spent fuel decay heat generation rates calculated using the ORIGEN2 code are compared with 133 calorimeter measurements of the decay heat rate from 81 spent fuel assemblies. The comparisons include both BWR and PWR assemblies. The range of decay time covered by the comparisons is from 860 to 4566 days out of reactor at the time of measurement. The exposure range of the measured assemblies is from 5.3 to 39.3 Gwd/Mtihm. The measured heat outputs ranged from 19 to 1550 watts. ORIGEN2 calculations agreed with the measurements with the calculation an average of 2.8% higher than the measurement. The standard deviation of the difference between the calculation and the measurement was 10.9%.
