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 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. 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 Electra laser system is currently being developed at the Naval Research Laboratory to serve as a test bed for laser driver technologies needed for an inertial fusion energy power plant. The main amplifier has produced 730 J of laser light operating in an oscillator mode. These results as well as advancement of the laser physics, electron beam deposition, and the pulse power technologies give us projections of >7% wall plug efficiency for an IFE system. The Electra main amplifier in oscillator configuration has run continuously at 1 Hz, 2.5 Hz, and 5 Hz for multi-thousand shot runs.This paper will discuss recent results of the Electra program at the Naval Research Laboratory including integrating the Electra main amplifier into a complete laser amplifier system. Issues addressed will include development paths for the cathode, window coating, and foil longevity to attain the durability required for a fusion power plant.
