Fission product decay heat studies of December 15, 1975

PDF Version Also Available for Download.

Description

The purpose of the project described is to study fission product decay heating rates, with emphasis on short decay times. Isothermal calorimetry is used to perform benchmark experiments for decay times between 20 seconds and 2000 seconds with an absolute accuracy of better than 5 percent. Experiments are being done with $sup 235$U and will be done eventually with $sup 239$Pu. Thermal neutron spectra are used for the irradiations. The project was initiated in July 1974. Final results for $sup 235$U are expected by 6-30-76, and for $sup 239$Pu by 1-1-77. Final reports for each task will follow the final ... continued below
