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.”

Nondestructive examination methods are particularly useful in characterizing radioactive waste. Radiographic examinations combined with tomodensitometric examinations (scanner) using a gamma-ray photon source make it possible to conduct exhaustive testing of the physical homogeneity of a low- or medium-activity waste package. These methods provide original experimental data for the following purposes: (a) preliminary characterization of packages for approval of the treatment process, (b) quality control of the produced packages (production control at the producer’s site and counterchecks by the waste control organism), (c) examination of packages, and (d) activity computation codes based on the emergent activity. The selection criteria, the physical principles, and the originality of the tool and some of its applications are described.
