SNF Calculations of Spent Fuel Source Terms for Fuel Pools and Storage Casks

摘要

Based on the validation of SNF against experimental data and ORIGEN-ARP decay calculations, it is concluded that the characteristics of spent fuel assemblies are calculated with high accuracy. Experimental decay heat comparisons with a total of 49 BWR and PWR fuel assemblies have shown an average C/E-ratio of 0.994 ±0.019. Routine applications include cask loading analyses and core- and fuel pool decay heat calculations.
