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.”

This paper presents dose calculations due to oxidation-driven mobilization of a vanadium alloy, V-4Cr-4Ti, exposed to air. We concentrate on air because it is highly unlikely that the vanadium alloy will be used with a water coolant. We calculate the offsite dose using data from transpiration tests together with information from activation calculations and the radiological hazard of the material from a dose code. We compare the early dose as a function of temperature from V-4Cr-4Ti with the early dose from tungsten, copper, 316SS, and a low activation ferritic steel. The vanadium alloy dose is almost an order of magnitude lower than the dose from the other materials for the entire temperature range examined, 600-1200°C.
