ANS is committed to advancing, fostering, and promoting the development and application of nuclear sciences and technologies to benefit society.
Explore the many uses for nuclear science and its impact on energy, the environment, healthcare, food, and more.
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.”

Nonaxisymmetric error fields arising from departures of the coil systems from axisymmetry can pose serious problems for the tokamak divertor. The X points of the divertor are particularly sensitive to being shifted by n ≠ 0 error fields; toroidal “bundle diverting” or bunching of heat flux coming from the core of the tokamak can produce hot spots on carefully designed divertor structures. Toroidal variation of the angle of incidence on the divertor by the n ≠ 0 error field can also locally peak the heat flux. Multiple field line tracing of a typical diverted Tokamak Physics Experiment (TPX) configuration with nonconcentric poloidal field (PF) coils is used to predict that if the toroidal variation of the peak divertor heat flux is to be kept to within ±25%, the principal PF coils responsible for the diverting must be aligned to ±2 mm of concentricity with the toroidal field.
