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.”

An experimental study confirms the possibility of initiating nuclear fusion reactions in metal-deuterium targets by bombarding them with ions that are not the reagents of the fusion reaction, in particular, with noble gas ions. The yields of (d, d) and (d, t) reactions were determined as functions of energy (0.4 to 3.2 MeV) and mass of incident ions (He+, Ne+, Ar+, Kr+, and Xe+). It is shown that at ion energies of ∼0.1 to 1 MeV, the yields of these reactions are rather high (10−10 to 10−7 event/ion), and they can be increased by raising the incident ion energy, by an appropriate choice of the target. Practical applications of the effect are discussed.
