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 plasma potential formation is investigated in a fully ionized collisionless plasma flow in the presence of electron cyclotron resonance (ECR) heating (ECRH) under simple diverging magnetic-field configurations. When ECR takes place in a diverging region, there appears a strong potential drop along the field lines, which results from a field-aligned electron acceleration, being accompanied by an effective ion acceleration so as to maintain the charge neutrality condition in the downstream region. Time-resolved measurements are performed in order to clarify dynamics of the potential formation.
