Description
The ENDF/B-VI [Evaluated Nuclear Data File] data evaluations reflect several major changes relative to version V data that will be of interest in thermal reactor analysis. Some of the important changes in the 235U, 239Pu, and 238U data are summarized. It can be seen that significant modifications have been made in the 235U and 239Pu thermal data. Also, completely new resonance evaluations based on the Reich-Moore formalism have been performed for 235U, 239Pu, and 238U, and the number of resolved resonances included in the evaluations has increased dramatically. To assess the merit of these modifications, it is first necessary to review the performance of ENDF/B-V in thermal reactor analysis and then to project the estimated impact of ENDF/B-VI on the version V results
