NE 591-603 Nuclear Criticality Safety

3 Credit Hours

This course will cover fundamental and advanced topics of nuclear criticality safety and will include a review of basic reactor theory and reactor physics as well as applied methods of criticality safety practice for the handling, storage, and processing of fissile and fissionable materials outside of reactors. The course will also cover a review of criticality accidents, fundamental concepts of establishing subcritical safety limits, the Double Contingency Principle, historical and contemporary methods for performing criticality safety analyses, and evaluations and criticality code and cross section data benchmarking and uncertainty analysis.
