Decay heat analysis for an LMFBR fuel assembly using ENDF/IV data

Recently evaluated ENDF/B-IV fission product data have been used in decay heat calculations for typical LMFBR fuel assemblies exposed to 100,000 MWd/MT burnup. The decay heat and radioactivity of the fuel assemblies have been calculated as a function of time from discharge. Important contributors to the decay have been identified.
