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.

Vogtle-3 shuts down for valve issue
One of the new Vogtle units in Georgia was shut down unexpectedly on Monday last week for a valve issue that has since been investigated and repaired. According to multiple local news outlets, Georgia Power reported on July 17 that Unit 3 was back in service.
Southern Company spokesperson Jacob Hawkins confirmed that Vogtle-3 went off line at 9:25 p.m. local time on July 8 “due to lowering water levels in the steam generators caused by a valve issue on one of the three main feedwater pumps.”

A reactor concept is proposed to improve economical competitiveness of the tokamak fusion reactor with aggressive physics and engineering assumptions. Key elements are high field magnets with Bmax=21T with high normalized beta βN=4.2 with 80% bootstrap current fraction and the radiative divertor. The power plant should have large net electric power (~3.4GWe) with twin tokamak reactors. Significant simplification of tokamak auxiliary system is also required.
