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.

ANS designates Armour Research Foundation Reactor as Nuclear Historic Landmark
The American Nuclear Society presented the Illinois Institute of Technology with a plaque last week to officially designate the Armour Research Foundation Reactor a Nuclear Historic Landmark, following the Society’s decision to confer the status onto the reactor in September 2024.

Radial, azimuthal, and axial xenon oscillation experiments were performed at Maine Yankee to confirm experimentally the theoretical predictions of stability with respect to these three primary modes of xenon oscillation. These experiments and the evaluation of the data to obtain damping factors are discussed briefly, and the results are compared with predictive calculations. Calculated damping factors, based on linear modal analysis techniques using a best estimate of the total power coefficient, are found to lie within the uncertainty bounds of the experimentally determined damping factors. The results of the axial experiments are also used in conjunction with results from calculational models to estimate the time in life at which the onset of divergent axial xenon oscillations may be expected.
