Decay Heat of Sodium Fast Reactor : Comparison of Experimental Measurements on the PHENIX reactor with Calculations performed with the French DARWIN package

摘要

A Decay Heat (DH) experiment on the whole core of the French Sodium-Cooled Fast Reactor PHENIX has been conducted in May 2008. The measurements began an hour and a half after the shutdown of the reactor and lasted twelve days. It is one of the experiments used for the experimental validation of the depletion code DARWIN thereby confirming the excellent performance of the aforementionned code. Discrepancies between measured and calculated decay heat do not exceed 8 %.
