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.

Sixteen days of high-power operation following a prolonged low-power irradiation resulted in the same percentage release of fission-product gases as that from UO2 fuel irradiated only at the high power level. The release of fission-product gas during a prolonged low-power cycle was not increased by previous irradiation at higher powers.
