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.”

It is possible, through nuclear reactions, to transmute long-lived radionuclides into shorter-lived or stable nuclides. Much attention has recently been focused on approaches to transmutation of spent nuclear fuel and on the potential benefits and risks of transmutation. Drawing on findings from studies carried out in different countries, this paper assesses the potential impacts of transmutation in standard thermal and fast reactors. A parametric scoping using standard methods to analyze mass flows and waste hazards gives a sense of the limitations and key variables in transmutation. With respect to waste, the impacts of the transmutation effort are found to depend strongly on the separation efficiency of the reprocessing system, the performance of the disposal repository, and the transmutation rate in the reactor.
