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.

NRC agrees to reevaluate seismic risk at Diablo Canyon
In response to a petition filed by environmental groups earlier this year, the Nuclear Regulatory Commission will reinvestigate earthquake fault lines and the potential for seismic activity and ensuing damage at California’s Diablo Canyon nuclear power plant.

A detailed analysis is made showing the feasibility of producing a neutron spectrum that will closely match the first wall neutron environment of any proposed future fusion reactor. An intense neutron source based on the deuterium-tritium reaction and producing 1 to 3 × 1015 14-MeV neutrons per second in a small volume, <1 cm3, is used as the primary source. The spectrum is tailored by surrounding this source with a spherical blanket composed of concentric shells of lithium, uranium (93% 235U), and beryllium. The irradiation volume of ∼100 cm3 is located between the source and the inside of the blanket and can be used for the purpose of radiation damage evaluations.
