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 spent electrolyte arising from pyroprocessing should be recycled to reduce the volume of high-level radioactive waste. To establish the spent electrolyte process by a phosphate conversion method, a preliminary experiment that followed a thermodynamical approach and used an electric furnace under argon gas atmosphere was carried out. The results obtained are that most thermodynamic properties of target phosphates acquired by the CALPHAD method were good in agreement with the experimental result; lithium and rare earth elements (REEs) tend to form the precipitate as orthophosphates, but other alkali metal (AL) and alkaline earth metal elements do not form the orthophosphate particles; and some elements such as ALs could form insoluble double salts with REEs.The development of separation techniques of insoluble and soluble fission product elements will be the next challenge.
