A criticality safety assessment of uranium compound storage at the Oak Ridge Y-12 Plant

Highly enriched uranium recovery operations at the Oak Ridge Y-12 Plant require storage of compounds generated by the processes. These fissile compounds are stored in process containers of various dimensions, depending on the compound. The process containers are stored on racks grouped together to form major storage arrays. This study assesses the sensitivity of a generic array model to the various process container loadings and additional parameters of relevance to criticality safety, and demonstrates the adequate safety margin of the storage arrays
