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 passive safety strategy for fusion can be summarized as three options: Inventory-based passive safety, Mobility-based passive safety, and Confinement-based passive safety. The determination of the dose limits for the public must follow a risk-based approach, where “risk” is the product of frequency times consequence. Ignitor is a high magnetic field tokamak, aimed at studying the physics of ignited plasmas. The site chosen for construction is the nuclear site of Saluggia (Northern Italy). The safety goal for Ignitor is the classification as a mobility-based passively safe machine. This choice is based on several assessments, and application of the ALARA principle. Evaluation of plant inventories and operation, and experience from other fusion machines have lead to conclusion that the above limits are the lowest reasonably achievable. The limits, however stringent, to not present a burden to plant operations. A comparison of Ignitor and ITER risk-based curves is finally carried out.
