Decay Data Comparisons for Decay Heat and Inventory Simulations of Fission Events
This supplement to CCFE-R(15)28 provides the detailed data from simulations of fission pulse events from 15 fissile nuclides which are constituents of nuclear reactors around the world. For each nuclide, a specific energy for the fission yield has been selected and monoenergetic pulses of 1E16 neutrons over 1 ns onto 1E24 atoms have been simulated. The decay heat, spectroscopic and total, for each nuclide within the resulting inventory has been recorded for each of five cooling times: 10, 100, 1000, 50111 and 10000 s. Decay heat from the fuel itself and the capture product of the fuel has been set to zero in all cases.
