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 impact of the nuclear option in the national energy outlook on the environment and the U.S. economy is analyzed with the MARKAL-MACRO energy systems computer code. The base case projection by the U.S. Energy Information Administration is the starting point for this study. The possibility of license renewal of the current fleet of U.S. nuclear power plants is considered as well as the introduction of cost-competitive advanced light water reactors. Electricity energy sector projections for fossil fuel plants, renewable energy sources, and nuclear power plants are analyzed on a least cost basis. The impact of constraints on the emissions of greenhouse gases is included in the analysis. It is found that it would be economically favorable to introduce as many as 300 additional nuclear power plants in the United States by the year 2025 to meet emission constraints of limiting emission to the 1990 level in the years beyond 2010.
