Abstract
Analyses of thermal plutonium solution critical benchmark systems have indicated a de ciency in
the 239Pu resonance evaluation. To investigate possible solutions to this issue, the Organisation for
Economic Co-operation and Development (OECD) Nuclear Energy Agency (NEA) Working Party
for Evaluation Cooperation (WPEC) established Subgroup 34 to focus on the reevaluation of the
239Pu resolved resonance parameters. In addition, the impacts of the prompt neutron multiplication
(nubar) and the prompt neutron ssion spectrum (PFNS) have been investigated. The objective of
this paper is to present the results of the 239Pu resolved resonance evaluation e ort.
