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 pebble divertor concept is to use the flow of multi layer pebbles as plasma facing component In the divertor plasma, the falling behavior of pebbles is affected by various forces: electromagnetic force, electrostatic force, plasma static pressure and plasma momentum flux. The forces against pebbles in divertor plasma are calculated by referring the edge modeling result of an ITER CDA type divertor. The result of the calculation is that the behavior of pebbles is dominantly affected by the plasma momentum flux. The influence of the electromagnetic force, the electrostatic force and the plasma static pressure can be negligible.
