~(239)Pu data of JENDL-3.3

摘要

~(239)Pu data of JENDL-3.3 were originally evaluated in 1987. After then, fission cross sections of important heavy isotopes, ~(233)U, ~(235)U, ~(238)U, ~(239)Pu, ~(240)Pu and ~(241)Pu were simultaneously evaluated and its results were adopted for JENDL-3.3. Integral test of JENDL-3.3 made by other authors showed that JENDL-3.3 well reproduced the k-eff of Pu-ruelled FBR critical cores and thermal reactors within about 0.5%. The C/E values of F25/F49 and C28/F49 in ZPPR-9 core were 1.02 and 1.04.
