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.

To quantify the core barrel motion in a typical pressurized water reactor, a scale factor was calculated for both one- and two-dimensional geometries, using forward, variational, and perturbation methods of discrete-ordinates transport. The calculational results show that, although perturbation theory is adequate for estimating the scale factor, two-dimensional geometric effects are important enough to rule out the use of a one-dimensional approximation for all but the crudest calculations. Also, contributions of gamma rays can be ignored, and the results are relatively insensitive to the nuclear cross-section set employed. A method was then developed for inferring, with the aid of this scale factor, the magnitude of the core barrel motion from the following statistical descriptors: cross-power spectral density, auto-power spectral density, and amplitude probability density.
