Estimation of Fission Product Spectra in Discharged Fuel from Fast Reactors

The fission product spectra in discharged fuel from fast fission power reactors have been calculated over a wide range of operating conditions (reactor operating times from 10 to 10,000 days and cooling times from zero to infinity). These calculations are based on recent yield data for fission of uranium and plutonium. From these calculated data are presented derived data of total curies and energy dissipation rates as functions of operating time and cooling time.
