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.”

A precise hydrogen permeation experiment for beryllium was conducted at a temperature ranging from 735 to 1000 K under hydrogen gas pressure of 101 to 103 Pa. Diffusion coefficient and permeation coefficient were determined from the steady state penneation and time transient penneation independently. The steady state penneation rate was proportional to the square root of H2 pressure and the time sequence of penneation rate agreed well with theoretical one, indicating that the penneation controlled by bulk diffusion. The temperature dependencies of the penneation coefficients (Φ) and diffusion coefficients (D) were respectively,Φ=(1.0±0.1)×10−6exp[−73±20(kJ/mol)/RT] (mol·m−1·s−1·Pa1/2),D=(1.3±0.1)×10−7exp[59±20(kJ/mol)/RT] (m2·s−1).Solubility calculated from the relation Φ=DS wasS=7.1 exp[−14(kJ/mol)/RT] (mol·m−3·Pa−1/2).
