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.

Countering the nuclear workforce shortage narrative
James Chamberlain, director of the Nuclear, Utilities, and Energy Sector at Rullion, has declared that the nuclear industry will not have workforce challenges going forward. “It’s time to challenge the scarcity narrative,” he wrote in a recent online article. “Nuclear isn't short of talent; it’s short of imagination in how it attracts, trains, and supports the workforce of the future.”

A fusion reactor blanket having a large tritium breeding ratio (TBR) is proposed. The blanket has a front breeder zone on the plasma side near its multiplier. A suitable zone thickness is 1 cm when 6Li enrichment is 50%. Combined with a multiplier composed of only ∼18-cm-thick beryllium, the TBR is maximized at a value over 20% larger than that of a blanket without a front breeder zone. Since the beryllium multiplier is supposed to include 5% of SUS as structural material in addition to cooling channels, a 12-cm-thick multiplier gives the maximum TBR as >1.4 for the blanket with the front breeder zone.
