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 main objectives of a TRISO treatment are to effectively breach and separate the carbon and SiC layers composing the TRISO particles. The reported technologies used to treat a spent TRISO fuel are almost identical, involving a final wet chemical process under which crushed TRISO fuel is processed to separate the coating layer fines from the kernel. Also, these processes are mainly powder processes with a secondary waste generation, and they require a corrosive solution as well as complex processing steps.Hence, two innovative processing concepts are proposed in this investigation; namely, a thermal shock and a pyrochemical process to breach the coating layers of the TRISO particle with a minimal amount of secondary waste. The preliminary results showed that the chemical vapor deposition (CVD) SiC layers, as pseudo coating layers of the TRISO fuel, exhibited very robust thermal shock behaviors even at 1300°C of T, but a cyclic thermal shock caused a drastic degradation of their hardness. Also, it was confirmed that the CVD SiC as well as the glassy carbon rod can be breached by a chemical reaction in a molten salt with Mg and Li, respectively. Therefore, the proposed technologies are found to be very promising for treating a spent TRISO fuel without a considerable generation of secondary wastes.
