Title: Nuclear Mass Inventory, Photon Dose Rate and Thermal Decay Heat of Spent Research Reactor Fuel Assemblies (Rev. 2)

Abstract

This document hasbeen prepared to assist research reactor operators possessing spent fuel containing enriched uranium ofUnited States origin to prepare part ofthe documentation necessary to ship this fuel to the United States. Data are included onthe nuclear mass inventory, photon dose rate, thermal decay heat, and fission product decay rate of spent research reactor fuel assemblies. Isotopic masses of U, Np, Pu and Am that are present inspent research reactor fuel are estimated for MTR,TRIGA andDIDO fuel assembly types. Theisotopic masses of each fuel assembly type are given as functions ofU-235 burnup in the spent fuel, and of initial U-235 enrichment and U-235 mass in the fuel assembly. Photon dose rates of spent MTR, TRIGA and DIDO-type fuel assemblies are estimated for fuel assemblies with up to 80% U-235 burnup and specific power densities between 0.089 and 2.857 MW/kg 235U, and for fission product decay times ofup to 20 years. Thermal decay heat load and fission product radioactivity is estimated for spent fuel based upon the fuel assembly irradiation history (average assembly power vs. elapsed time) and the spent fuel cooling time.
