1.3 The identical decay heat power values shall be applied for all reactor conditions and events, nainely; normal, upset, emergency, and faulted. 1.4 The decay heat power values in this document are based on the shutdown of An infinite thermal reactors fueled with Uranium (U-235 and U-238 mixtures). irradiation period at maximum reactor power and a recoverable fission energy of Neutron capture effects by the 200 MeV/ fission are assumed prior to shutdown.These assumptions result in conservative fission products arq not considered.
