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 important mechanisms of energy flow in a quasi-isobaric magnetic fusion device have been studied in a three-part paper. In Part I, the spatial profiles of plasma parameters that yield acceptable values of Qdt and plasma dimensions, were determined. These profiles were determined by balancing the dominant terms in the differential energy equations, i.e., conduction, bremsstrahlung, and collisional energy exchange, against each other. One class of equilibria was identified for a more detailed study. In Part II, the contributions of inelastic processes, radiation transport, and alpha-particle heating were studied. These terms, in combination with the dominant terms studied earlier, yield the spatial profile of external heating that is required to balance the energy equations everywhere in the plasma. In Part III, the results of ray-tracing calculations for waves in the lower hybrid range are reported. These calculations show that it is possible to produce such a deposition profile for both electrons and ions, if the launch structure can couple the required k spectrum through the high-density edge plasma.
