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.”

The poloidal field coil system in a tokamak provides the equilibrium, control and shaping fields for the plasma as well as the flux change which induces plasma current and ohmic heating. In CIT all the main coils will play an active part in all these functions. The PF system consists of 16 coaxial coils which will be external to the TF coils and located symmetrically in pairs with respect to the midplane of the machine. Six of the 16 coils comprise the central solenoid assembly. The OH solenoid will have a bore diameter of 0.68 m, an OD of 1.4 m, a height of about 4.0 m, and a central field of almost 22 T. Geometric restrictions are such that an aggressive structural concept for the conductor is required; hence, the coil will consist of a stack of explosively bonded copper/steel plates. Each plate is machined by a water-jet cutting process. This paper presents features of the design and selected results from an R&D program which is underway.
