Abstract

A resonance analysis of the ²³³U data in the neutron energy range from thermal to 600 eV was done with the SAMMY computer code. The analysis included the most recent high-resolution neutron transmission and fission data, in particular those data measurements performed at ORELA. The Reich-Moore resonance formalism and the Bayes' approach of the SAMMY code were used to analyze the experimental data, leading to a set of 769 s-wave resonances for which 738 resonances are in the energy range from thermal to 600 eV and 31 resonances placed at negative energies and above 600 eV. Benchmark calculations were done to test the performance of the ORNL ²³³U evaluation and comparisons were done with results of calculations obtained with current ²³³U evaluation on the ENDF/B-VI library.
