Junk And Dangerous Plant Grand Gulf Is Restarting?

Update Dec 24

98% power

Once they got past the three day delay at low power, then not a bad startup. We still could have a Christmas scram? A host of agencies and news sources are closely watching these guys over poor power operation, I hope they don't take chances to "look good" for their audiences.      

Update Dec 21

That is more like it. 78% power

Update Dec 20

Check out this new LER? These guys have what we call a ground detector monitor. They can measure any ground on the plant whether large or small in the control room. Many junk plants have many grounds that just show up. They have so many, they just ignore the grounds. Did Grand Gulf have any abnormal indications on the ground meter?  

Basically stuck in the low twenties percent power for three days. Like I said, a very non professional startup. Most plants can get to the high 90% percent in two or three days. I guess they are changing a flat while the plant is up at power. I am convinced it is the condensate and feed system or turbine control that is sticking point. In my days, per NRC approved procedures, you had a long list of systems and components on a official paperwork. All these systems needed to be tested and found fully functional. If you put any checkmark on the list indication problems on any component or systems, it was illegal to startup the plant. In the old days, plant management would startup a plant with a host of equipment broken, degraded or undergoing maintenance. They were intending to repair the equipment at power. The plants went crazy with this unsafe and non conservative. You know, only a few outlier bad plants with malicious practices ruin it for the rest of the good plants. That is how we got that list forcing us to startup with a clean plant. Tons of over regulation occur because these few bad operators.           


Update 19

See what I am saying? Stuck at 18%. It looks like they knowingly started up the plant with components of condensate and feed system broken. Hoping they would fix it at power.

And one plant in ANO tripped.

Event Text

AUTOMATIC REACTOR TRIP - LOSS OF NON-VITAL BUS

"On December 18, 2018 at 1126 CST, Arkansas Nuclear One, Unit 1 (ANO-1) reactor automatically tripped due to a loss of the A-1, non-vital 4160V bus. All control rods fully inserted. Loss of the A-1 bus resulted in de-energizing A-3 vital 4160V bus. Emergency Diesel Generator #1, K-4A, started automatically and is currently powering A-3 vital bus. Non-vital buses A-2, H-1, and H-2 and vital bus A-4 transferred power automatically to the Startup Transformer #1. Off-site power remains energized and available for ANO-1. The reason for loss of A-1 bus is unknown at this time. Currently, ANO-1 has stabilized in Mode 3, Hot Standby."

Decay heat is being removed by the main condenser using the turbine bypass valves. The loss of the A-1, non-vital bus, is under investigation. The licensee has notified the NRC Resident Inspector and the state. 
Update Dec 18

Sorry Pathetic pace at 18% in one 24 hours. Pathetic pace at 4% yesterday, 18% today...  It reminds me of a newly licensed car driver who drives ridiculously showed in order for him to compensate for his poor driving skills.

Brand new problem identification inspection report. The NRC system is fundimentally a bureaucratic absolution system. The plant does a sin, everyone does a ton of paperwork including the NRC, but no fundamental change. They are dinging these guys with harmless papercuts...
The inspectors observed meetings of the station’s Plant Health Committee (PHC) on  October 22 and November 5, 2018.  According to the licensee’s governing  Procedure EN-DC-336, “The primary mission of the PHC is to identify, prioritize, and drive resolution of issues challenging unit reliability,” by focusing on things such as, “safety system health and “organizational alignment . . . to resolve equipment reliability issues.”  The procedure further provides that the PHC meetings should be, “action oriented and results driven, rather than weighted more to status / update / discussion.”  While this PHC process is not a safety-related or quality process as is the CAP, it serves an important oversight function of problem identification and resolution processes, particularly for ensuring appropriate attention and resources are focused on broad challenges that are evidenced by a series of more discrete issues that may be documented and addressed in the CAP.  The inspectors observed that contrary to PHC goals and procedural direction, discussions at the meetings were focused almost entirely on what actions had been complete, rather than proactive discussions of strategies for issue resolution.
***I doubt this will be a professional startup...

4% power today???
