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 proposal has been made to measure the compressed fuel areal density, ρR, in inertial confinement fusion targets by detecting the radionuclides produced by the absorption of fusion charged particles in the target shell material. Calculations were performed for a deuterium-tritium pellet surrounded by a shell of either Li2SiO3 or B2O3, and the ratio of the number of proton reaction products in 7Li, 10B, or 11B to the number of deuterium-deuterium neutrons was obtained as a function of pellet ρR. The results show a strong dependence of this ratio on ρR for ρR values between 0.01 and 2.0 g/cm2. Methods for independently determining fuel ion temperature and shell ρR are also discussed.
