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 thermal interaction of certain molten materials such as Al2O3 with water results in vapor explosions with very high (supercritical) pressures and propagation velocities. A quasi-steady-state analysis and a transient analysis of a supercritical vapor explosion in one-dimensional multiphase flow were applied to analyze experimental data of an Al2O3-water fuel/coolant interaction obtained from the KROTOS 26, 28, 29, and 30 tests. The shock adiabatic thermodynamic model and the TEXAS mechanistic model were used to perform this analysis. The predicted results of the initial vapor void fraction and explosion conversion ratio from both models, together with the estimated experimental results, for the KROTOS 26 test were compared.
