Nuclear Criticality Experiments

Nuclear criticality experiments are the fundamental validation basis for radiation transport, criticality safety, and reactor dynamics simulation tools. The ORNL team supports the development, review, archival documentation, and use of nuclear criticality experiments around the globe. SCALE’s S/U capabilities are applied in the design of optimized criticality experiments at US and international facilities to best meet targeted validation needs with the most efficient use of resources. This work is primarily performed in support of the US DOE Nuclear Criticality Safety Program.
