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.”

A shielding analysis of the IGNITEX device proposed by the University of Texas as a relatively inexpensive way to obtain an ignited plasmas has been performed. This paper emphasizes the radiation streaming effects on the radiation environment in the IGNITEX machine. The analysis was done by using a three-dimensional Monte Carlo code, MCNP, along with a one-dimensional discrete ordinate code and simple analytical formulas. The results show that the streaming effect on the global radiation in the test cell is not significant. The vacuum and maintenance penetrations, in particular, straight ducts, increase the radiation level at and near the outlet of the ducts considerably. The vacuum fuel processing and fueling rooms should be specifically shielded from the test cell. Access during the pulses must be limited since the radiation level in these areas is very high during D-T burning pulses because of the radiation streaming from the test cell.
