Revised decay heat tables for Mark 16B, Mark 22 and Mark 31 assemblies for use in ECS (Emergency Cooling System) analyses

Technical Report ·
OSTI ID:6961225
This report provides documentation of current calculations of the decay heats. These decay heats were obtained with procedures which will support a quality assurance audit of ECS analyses. The decay heat tables have also been extended to longer cooling times to support ECS analyses of potential interest to the Probabilistic Risk Assessment (PRA) program. These tables will allow calculations of the heat deposited in Mark 16B, Mark 22, Mark 31A, and Mark 31B assemblies by the processes of fission product decay in LOCA (loss-of-coolant-accident) and LOPA (loss-of-pumping-accident) scenarios. The theory and procedures for such assembly deposited power calculations are given in reference 6.
