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.

The dynamic behavior of the Superphénix core was tested during commissioning of the plant. From comparison of experimental and calculated results, it was concluded that the time-dependent parameters agree quite well. The comparison is based on DYN system code calculations and on tests performed at zero power (reactivity step leading to a self-stabilization) and at power (steps on reactivity, primary flow, and secondary flow). These tests checked the behavior of the nuclear steam supply system.
