Decay heat measurements by fast-response boil-off calorimetry. [BWR; PWR]

Conference ·
OSTI ID:7301911
A liquid-helium boil-off calorimeter with a 1-s time constant was used to measure /sup 235/U fission product decay heat at times between 10 and 10/sup 5/ s following a 2 x 10/sup 4/ s thermal neutron irradiation. The uncertainty in the data was approximately 2% (1 sigma) except at the shortest cooling times, where it rose to approximately 4%.
