Fission Product Decay Heat Calculations for Neutron Fission of ²³²Th

Precise information on the decay heat from fission products following times after a fission reaction is necessary for safety designs and operations of nuclear-power reactors, fuel storage, transport flasks, and for spent fuel management and processing. In this study, the timing distributions of fission products' concentrations and their integrated decay heat as function of time following a fast neutron fission reaction of ²³²Th were exactly calculated by the numerical method with using the DHP code.
