Current status of the doe nuclear criticality safety program hands-on criticality safety training course at sandia

Topical Meeting Held by the ANS Nuclear Criticality Safety Division, NCSD 2013 - Criticality Safety in the Modern Era: Raising the Bar

Harms, Gary A.; Knief, Ronald A.; Miller, Allison D.; Ford, John T.

A hands-on critical-experiment training class has been developed by the US DOE Nuclear Criticality Safety Program using the water-moderated pin-fueled critical experiments at Sandia National Laboratories. The class is offered as part of the NCSP training program for Nuclear Criticality Safety Engineers in a facility that allows attendance by both cleared and uncleared personnel. Laboratory exercises have been developed that demonstrate the effects of varying a number of the parameters that are considered important to criticality safety. Accompanying the experiments is a series of classroom presentations that emphasize the concepts that are demonstrated in the experiments.

Results of critical experiments on water-moderated fully-reflected 6.90% enriched UO2 fuel pin arrays with a fuel-to-water volume ratio of 0.52

Topical Meeting Held by the ANS Nuclear Criticality Safety Division, NCSD 2013 - Criticality Safety in the Modern Era: Raising the Bar

Harms, Gary A.; Miller, Allison D.; Ford, John T.

The Seven Percent Critical Experiment (7uPCX) at Sandia National Laboratories was designed to provide benchmark criticality and reactor physics data for water-moderated pin-fueled nuclear reactor cores in the 5 to 10 percent enrichment range. Approach-to-critical experiments were performed on fifteen roughly cylindrical pure water-moderated and -reflected 7uPCX configurations with a fuel-to-water volume ratio of 0.52. Those configurations are described and the results of the measurements are reported in this paper.

Benchmark experiments in water-moderated fully-reflected 6.90% enriched UO2 fuel rod lattices with a fuel-to-water volume ratio of 0.52

Transactions of the American Nuclear Society

Harms, Gary A.; Miller, Allison D.; Ford, John T.

A second set of experiments in the Seven Percent Critical Experiment (7uPCX) has been completed. Additionally, an evaluation of the experiments as criticality safety benchmark experiments has been performed. The Reviews of the benchmark evaluation have been completed. This evaluation will be published in the 2013 edition of the International Handbook of Evaluated Criticality Benchmark Experiments as LEU-COMP-THERM-078 (LCT078). This presentation is a brief tour of these experiments.
