Improvement of Reference Nuclear Data for Commercial Power Reactor Analysis and Design.

摘要

This program concerns improving the performance of the ENDF/B library in thermal reactor applications. Under this project the analysis and data testing capability has been extended to thermal systems. Information on how the present version of the ENDF/B library is performing in thermal benchmark experiments has been obtained and will be used in the preparation of the next version of the library. One particularly persistent problem,the discrepancy between calculated and measured epithermal capture rates in 238U rods has been made the topic of a two day workshop-seminar organized by the contractor; a summary of the sessions is included in this report.
