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.”

The two plasma sources using a concentrically three-segmented plasma emitter are developed, with which the parallel and perpendicular flow shears can be controlled, respectively. Here the drift-like and Kelvin-Helmholtz instabilities are observed to be excited and suppressed depending on the parallel and perpendicular flow shears, respectively. On the other hand, propagation and absorption of right-hand (R) and left-hand (L) circularly polarized waves, which are related to plasma heating, are investigated under magnetic-mirror configurations. Not only R wave but also L wave is absorbed in the electron cyclotron resonance (ECR) region in the same way, which is considered to be caused by the polarization reversal from the L wave to the R wave. It is actually observed that the L wave is converted into the R wave near the ECR point depending on the electron temperature.
