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.

A method for determining the prompt neutron decay constant of a fast critical assembly by noise analysis has been developed. It uses a digital computer to do polarity crosscorrelation on the outputs of two scintillation detectors. For the first time, such a measurement has been made in a fast assembly at criticality with no intrinsic limitation on power level. Portions of the technique were adapted for a study of the dynamics of a digital reactor control scheme.
