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 dust mobilization in the vacuum vessel under the Loss-of-Vacuum-Accident (LOVA) event was measured quantitatively using the preliminary LOVA apparatus. The particle size distributions in the mobilized dust were characterized and analyzed using a high performance optical-microscope and image analysis software. It was found that around 10% of the initial dust weight was transported upward inside the VV when the breach located at the roof of the VV and an incoming flow from the outside through the breach directly hit the dust. On the other hand, the transported dust weight was less than 1% of the initial dust weight when the breach position was at the side wall of the VV and an incoming flow from the outside indirectly hit the dust. The relationship between the dust mobilization and breach position was clarified from the present experimental results.
