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.”

Balance-of-plant design aspects of two inertial fusion energy (IFE) reactor concepts - the laser-driven SOMBRERO and the heavy ion beam (HIB) driven OSIRIS - are being evaluated at a preconceptual level. The net electrical output of both plants is selected as 1,000 MWe (reference case). The economics of higher and lower capacities are also being evaluated. The heat transport system for both the reactors utilizes an intermediate loop with liquid lead as the intermediate coolant. An intermediate loop is chosen to reduce the potential of tritium migration to the environment. Both reactors utilize a supercritical pressure steam power conversion system with double reheat to achieve high conversion efficiency; a high efficiency is critical due to the capital-intensive nature of the plants and the low efficiencies of the laser and HIB drivers. The SOMBRERO plant facility is characterized by a large reactor building dictated by the laser optics configuration requirements. The plant also includes two moderate-size laser buildings. The OSIRIS plant facility is characterized by a moderate size reactor building, whose size is dictated by the remote maintenance requirements. In addition, a five-kilometer-long HIB tunnel is a unique feature of this plant. A remote maintenance approach is proposed for each of the reactors consistent with state-of-the-art methods and tools.
