Grand Gulf is down to 90% and River Bend is up to 87% I see we hit the spring outage time nationwide...
March 8 Now River Bend is at 14% and restarted...
March 4
So now Grand Gulf is down to 78% power. Its first big downpower since startup. River Bend is shutdown.
March 3
Much congratulation to Grand Gulf with staying up at 100% for two or three days. But now River Bend is down to 24% power...
March 1
Grand Gulf has been at 100% for days now. I doubt they will get by March without another trip. But now River Bend is in trouble. They came up slowly from their recent scram. They have been banging around 80-90% for many days now. Something was preventing them coming up to 100%. Today they are down to 24%. I have done this all to highlight the erratic and unreliable nature of Entergy...

Ok, so now Grand Gulf is at 100% power. So it took them 18 days to get to 100% power from startup. An atrocious amount of time.
River Bend: They have been stuck at 90% for days. The operations of these plants indicated they are highly erratic and unreliable operations. They are in quick decline...
Feb 20
I read the wrong columb. Grand Goof is a 93 power. Will they even get to 100% power before they trip.
Grand Gulf is finally at 100% power. Just think of this, it took at least 17 days for the plant to come up to 100% power. How is that good for a vital and critical societal need?
River Bend has been is stuck at 90% power

Grand Gulf is finally at 100% power
River bend is stuck at 90% FOR DAYS!!!!.
Jan 16
Grand Gulf 83%
River Bend 90%
Why has River Bend been stuck at 90% for 24 hours...
Update Jan 15
Hold your breath, Grand Gulf is near their peak power level (91%) last startup...
Grand Gulf 85%
River Bend 90%
Update Jan 14
Hmm, River Bend is pulling a Grand Gulf?
Grand Gulf 83%
River Bend 65%
Update Jan 13
Grand Gulf 63%
River Bend 85%
See this is driving me crazy. Why did Grand Gulf take a deep 22% drop in power, while River Bend is maintaining around 80% power? Why is Grand Gulf so unstable.
Update Feb 12
Jan 12 76% power
Jan 11 74%
Jan 10 55%
River Bend started up on Jan 10 (1% power) and is 81%
From the evidence, I just don't think it is a xenon problem. It might be some of it. I think something is going with the core or fuel.
Notice the event date and power level? The inner and outer airlock doors are supposed to be shut and tested before startup. It is not supposed to be opened until the next shutdown. On the far side of inner airlock door sits the reactor core. It is really radioactive inside that door. They had to open the door for a problem inside containment. I wonder if they actually went through the inner door a power? It is very abnormal. The failed seal in the inner door, they should have picked it up on the pre startup seal testing. I did leak rate testing on these doors all the time. They were inches thick metal door for employee radiation protection. The doors were very heavy. It took a lot of heft just to close the doors... I don't think a girl could close doors :)

Event Text
BOTH INNER AND OUTER CONTAINMENT AIRLOCK DOORS INOPERABLE AT THE SAME TIME
"On 2/10/18 at 1835 CST at Grand Gulf Nuclear Station, while the 208 ft. Containment Airlock Outer Door was tagged-out for planned maintenance, the 208 ft. Containment Inner Door was determined to be inoperable. Grand Gulf had performed 06-ME-1M23-R-0001, Personnel Airlock Door Seal Air System Leak Test, on the 208 ft. Containment Airlock Inner Door which had been deemed satisfactory. While performing planned maintenance on the outer door an additional review of the paperwork determined that the test was actually unsatisfactory on the inner door. TS 3.6.1.2 Condition C was entered at 1835 CST on 2/10/18 for both 208 ft. Containment Airlock Doors being inoperable. Maintenance of the Outer Door is expected to be completed, and the airlock returned to operable status, prior to TS required action completion time."
The licensee notified the NRC Resident Inspector.

Must be a xenon soak thing. Up 3% to 70%.
River Bend is still 0% from last scram.
Feb 8
67%
Feb 7
Still at 26%. So we are already at a highly abnormal startup. They just weren't ready for power operation...
River Bend is still shutdown.
Feb 6
Stuck at 26% for 24 hours. The fun begins.
Feb 5 26%
Feb 4 17%
Feb 3 1%
