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.

WIPP’s SSCVS: A breath of fresh air
This spring, the Department of Energy’s Office of Environmental Management announced that it had achieved a major milestone by completing commissioning of the Safety Significant Confinement Ventilation System (SSCVS) facility—a new, state-of-the-art, large-scale ventilation system at the Waste Isolation Pilot Plant, the DOE’s geologic repository for defense-related transuranic (TRU) waste in New Mexico.

A comparative analysis of three distinct classes of self-sufficient nuclear energy systems is undertaken: 1. fast breeder-converter system 2. deuterium-tritium fusion reactor 3. fusion-fission hybrid/symbiont. Consistent power and isotope balances are imposed and relevant performance criteria are established. While no one system seems to excel in all physical criteria, we find that the improved neutron economy of the combined fusion-fission system provides the basis for a substantial and enhanced range of fuel and energy production capacity.
