Times Cited Count：0 Percentile：0.01(Nuclear Science & Technology)Nuclear characteristic parameters were calculated and subcriticality judgement graphs were drawn for revision purposes of the Data Collection for the Nuclear Criticality Safety Handbook. The nuclear characteristic parameters were the neutron multiplication factor in infinite media, migration area and diffusion constants for 11 kinds of typical fuels encountered in criticality safety evaluation of nuclear fuel cycle facilities. These fuels included ADU-H
O, UF6-HF and Pu(NO
)
-UO(NO) solution, of which data were not cited in the Data Collection. The calculation was made with the Japanese evaluated nuclear data library JENDL-3.2 and a sequence of criticality calculation codes, SRAC, POST and SIMCRI. The subcriticality judgement graphs that depict the region satisfying the inequality relation of the neutron multiplication factor less than 0.98 between the two variables (a) uranium enrichment, 239Pu/Pu ratio or plutonium enrichment and (b) H/(Pu+U) ratio were drawn for the same kinds of fuels except UF6-HF in infinite media.

The nuclear criticality safety handbook of Japan was first published in 1988, which was translated into English in 1995. This paper intends to introduce the American community of nuclear criticality safety to activities for revising the Japanese handbook, putting an emphasis on practical use of code validation. They include (1) publication of "Nuclear Criticality Safety Handbook, Version 2" and its English translation, (2) publication of "A Guide Introducing Burnup Credit, Preliminary Version," and (3) preparation of "Nuclear Criticality Safety Handbook, -Data Collection-, Version 2."

The academic subject of "nuclear data" is not learned in universities, and researchers on nuclear data have been supplied from the fields of nuclear physics and/or nuclear engineering. The production of nuclear data file, which is one of the most fundamental databases for research and development of nuclear energy applications, cannot obtain enough human resources. Japanese Nuclear Data Committee, namely "Sigma" Committee, considering to solve this issue continuously, for example, performing tutorial session in nuclear data symposium. However, it is still far from exhaustive point of view. This report introduces strategic plan of fostering human resources and production of a suitable textbook for nuclear data.
