REVIEW ON THE NEUTRON SOURCE STRENGTH OF HEU METAL BURST REACTOR

There were two similar series of burst waiting time experiments carried out on Godiva-II and Caliban respectively analyzed for neutron initiation study, unfortunately both the strength spontaneous fission source given in published papers are not consistent with data U-235 U-238. In this paper, discrepancies U-238 from different references reviewed clarified correct calculated respectively, then multiplication equivalence method arbitrary is introduced equivalent fundamental-mode(EFM) co-efficiencies MC software, lastly these HEU metal reactor EFM deduced. The reactors much less than proposed values used investigation new data, inconsistency to results presented discussed.
