Chlorine Nuclear Data Measurement and Evaluation, TerraPower

This project will perform new measurements of 35Cl(n,p), analyze the experimental data from these measurements, generate new 35Cl and 37Cl cross-section evaluations in ENDF/B format, and assess the impacts of the expected changes to chlorine nuclear data by comparing analysis of MCRE with updated cross-section libraries to results with existing nuclear data.

LEU+ UF6 Physical Chemistry Study, Orano Federal Services

Previous studies for UF6 limits in shipping containers were limited to enrichment up to 5%. The objectives of this new study will take that enrichment to 10%. The project will review the available literature and update these studies with current techniques, evaluate the impact of higher enrichments in safety criticality cases in transport conditions, and publish a report that will serve as the basis to the safety criticality analysis that will be provided for review and approval to the radioactive material transport regulators, for the DN-30 package with 30B cylinders containing enrichment higher than 5%.
