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.”

We researched the AIC (Alfvén Ion Cyclotron) instability. A magnetic probe using microchip-inductor is superior to size and easy to handle. In fluctuation measurement using the GNBP (Gold Neutral Beam Probe) the measured fluctuations may not be local density fluctuation because the beam ionization coefficient depends on not only the electron density but also the temperature, and the secondary beam is deflected by the magnetic field fluctuation, and the beam fluctuation is integrated along the beam trajectory. But we found by simulations such as the AIC fluctuation with small amplitude and high frequency these effects may be neglected. In initial experiment, the GNBP detected successfully the AIC fluctuations with high frequencies excited in the core plasma.
