Experimental validation of the decay power calculation code and nuclear databases - FISPACT-97 and EAF-97 and FENDL/A-2.0
Overall, the results of this particular validation exercise indicate that the calculational methods and nuclear databases, with some notable exceptions, generally allow predictions, with acceptable margins, of the decay power of the tested materials. This statement is only valid within the framework defined by the conditions of the experimental set-up in terms of materials, cooling times and neutron spectrum. The spectrum is very different from the spectra expected in next generation fusion devices, being very low in lower-energy neutrons: as a result, the reactions dominating the decay heat production in the FNS assembly, and validated in the experiment-calculational comparisons presented in this report, are often not the reactions predicted to dominate in the fusion power plant conditions.
