Division Spotlight
Operations & Power
Members focus on the dissemination of knowledge and information in the area of power reactors with particular application to the production of electric power and process heat. The division sponsors meetings on the coverage of applied nuclear science and engineering as related to power plants, non-power reactors, and other nuclear facilities. It encourages and assists with the dissemination of knowledge pertinent to the safe and efficient operation of nuclear facilities through professional staff development, information exchange, and supporting the generation of viable solutions to current issues.

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 intrinsic potential of a field-reversed configuration (FRC) for high-beta operation (beta values in the range of 50 to 100%) stimulates much interest in this device as an attractive candidate for a compact fusion reactor with high power density. Several additional benefits, e.g., the cylindrical geometry of the concept, the simplicity of the magnetic system, the simply connected plasma, the low synchrotron radiation, the divertor action of the open field lines, and the possibility for direct energy conversion of the charged-particle flow, justify a closer look at the benefits and problems of FRCs. The emphasis here is on operation with D-3He fuel under reactor-relevant conditions, whereas deuterium-tritium (D-T) is taken as a reference case. The reasons for that choice are that (a) D-3He offers intrinsic advantages over D-T in neutron production and radioactive inventory and (b) the high-beta regime of an FRC matches ideally some of the requirements for D-3He operation. A steady-state version of an FRC is considered to be more attractive than its pulsed counterpart. Frequent startup to high temperatures would be particularly detrimental for D-3He, where startup scenarios seem to rely either on the transition from D-T to D-3He, with unavoidable strong tritium contamination, or on high-power neutral beam injection.
