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 design of a feedback system based on the application of electron cyclotron (EC) current drive in high-density tokamak plasmas is presented. A realistic evaluation is given of the current drive produced by high-power gyrotron tubes for EC-wave beams injected from the low field side in the O-mode polarization. The driven current, calculated using a relativistic analytical formalism along the ray trajectories, is inserted in a consistent theory of nonlinear tearing-mode evolution. Results of modeling calculations are presented, showing the possibility of controlling by means of a digital system the evolution of the width of rotating magnetic perturbations by phase-locked modulation of the gyrotron power source.
