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 molten salt waste from a pryochemical process to recover uranium and transuranic elements is one of the problematic radioactive wastes to be solidified into a durable waste form for its final disposal. This paper suggests a new method as a dechlorination approach to the immobilization of salt waste. The inorganic composite consists of SiO2, Al2O3, and P2O5 (SAP), which can generate a series of reactive sites for metal chlorides when in contact with molten salt. Under an oxidative condition, metal chlorides were successfully dechlorinated and converted into metal aluminosilicate, metal aluminophosphate, and metal orthophosphate, which are manageable at a high temperature. The optimum mixing ratio of SAP/salt in weight is about 2, and a borosilicate glass shows good compatibility with the reaction products containing phosphate compounds. By using a glass, a highly monolithic waste form was successfully fabricated at 1100°C, and more than 33 wt% of mixing ratio of glass as a chemical binder increased the chemical durability of the waste form. Use of SAP as an effective stabilizer can offer a chance to avoid Cl-induced problems and control the vaporization of volatile elements. This allows a high degree of freedom in the fabrication of monolithic waste form.
