Junk Plant Grand Gulf: Trips, Down Powers And Slow Startups All Over The Place

Update June 24

Plainly these guys didn't prepare the plant for a starting. They started up with degraded equipment. 

June 24 51%

June 21 55%

June 20 41%

Update Sept 20

Fast startup and power at 41%. This guys are under the gun to save the grid. These guys are extremely fragile due to money problems and poor maintenance. This is double or nothing gambling. The crisis at Grand Gulf just entered a new phase...

***They aren't spending enough money on this guy. GG been tripping and down powers, repetitive slow startups all the time. The worst capacity factor in the nation. A big accident right around the corner.

Junk Plant Grand Gulf Restarted From 50 Day Outage...Lets Watch It Till 100% Power

Event Text

MANUAL REACTOR SCRAM

"At 1644 [CDT] a manual reactor scram was inserted by placing the Reactor Mode Switch to Shutdown. At 1643 [CDT] the Condensate Booster Pump A tripped on low suction pressure. At 1644 [CDT] the Reactor Feed Pump A tripped on low suction pressure. A Recirculation Flow Control Valve runback occurred as designed. Reactor Water level was approaching the Automatic Low Water Level 3 (11.4 inches) scram set point and manual actions were taken by placing the Mode Switch to Shutdown before the low level set point was reached. All systems responded as expected following the manual scram. The plant is stable in mode 3. This event is being reported under 10CFR 50.72(b)(2)(iv)(B), as any event or condition that results in actuation of the Reactor Protection System (RPS), when the reactor is critical.

"The NRC Senior Resident Inspector has been notified."

All control rods fully inserted, and decay heat is being removed through the turbine bypass valves to the main condenser. The licensee is investigating the cause of the event.
