Division Spotlight
Nuclear Criticality Safety
NCSD provides communication among nuclear criticality safety professionals through the development of standards, the evolution of training methods and materials, the presentation of technical data and procedures, and the creation of specialty publications. In these ways, the division furthers the exchange of technical information on nuclear criticality safety with the ultimate goal of promoting the safe handling of fissionable materials outside reactors.

Framatome signs contracts with Sizewell C
French nuclear developer Framatome is slated to deliver key equipment for Sizewell C Ltd.’s two large reactors planned for the United Kingdom’s Suffolk coast.
The agreement, reportedly worth multiple billions of euros, was announced this week and will involve Framatome from the design phase until commissioning. The company also agreed to a long-term fuel supply deal. Framatome is 80.5 percent owned by France’s EDF and 19.5 percent owned by Mitsubishi Heavy Industries.

The ZPPR-12 experiments conducted by Argonne National Laboratory were designed to study sodium void worth, cell heterogeneity, and neutron streaming. The small core made it possible to conduct sodium void and neutron streaming experiments over the entire core. The simple, clean, single-zone core had no internal structures such as internal blankets or control rods to affect measurements or complicate interpretation of experimental results. Criticality and selected sodium void worth measurements were evaluated for ZPPR-12, and a detailed uncertainty analysis was performed for the measurements chosen for the benchmark. Highly detailed as-built models were developed for all configurations selected for the benchmark. A simplified RZ model was also created for the criticality benchmark. MCNP5 calculations with ENDF/B-VII.0 data for the benchmark models show generally good agreement between calculated and benchmark values for keff and sodium void worth.
