Abstract
This paper describes an isothermal liquid helium boil-off calorimeter which was used to measure fission product beta and gamma radiation following exposure of 60-mg 235U foils to the thermal neutron flux in the Los Alamos Omega West Reactor. This work is part of a program sponsored by the U. S. Nuclear Regulatory Commission to provide better values of the fission product decay heat following reactor shutdown, for use in reactor safety evaluations. Particular effort was directed at reducing the uncertainty during early cooling times (10 to 1000 sec), where the present American Nuclear Society ANS-5.1 Decay Heat Standard [1] is assigned an uncertainty of +20% to -40%.
Work performed under the auspices of the U. S. Nuclear Regulatory Commission.
