Wasterford: Another Entergy's Dog Plant Trip or Manual Shutdown
I don't yet know why they shut down. It occurred on Jan 5. I hope River Bend being at 90% is just shaping the core. Grand Gulf, it is now your turn. It seems they got junk plant Palisades and Pilgrim turned around pretty quick.
NRC's Staff In Trouble
We are a week into 2019 and the NRC hasn't put a 2019 link into this important page yet. Waterford tripped, probably shutdown over the weekend. I can't click the 2019 link in order to reference back a few days, to figure out when Waterford tripped?

Entergy: Dog Plants Palisades and Pilgrim.
How close are we to collapse of a capacity factor accident. Remember these plants contain many millions of components. The complexity of the machines makes them a difference beast. If you ding the maintenance budget over and over, get away with really less than you need...you might not see any diffidence. There is a delay time on the decline of plant reliability. We are really getting into the realm uncertainty. If you plow a lot of money into the plant, you drastically reduce global uncertainty. Conversely, if you get a bad unexpectant accident, you might plow a ton of money, training and new people into the plant, but it would take years of this new intensity to even change the bad curve of reliability. And believe me, tons of money into a dog plant, new training, people, the NRC up your ass, this further disrupts the mojo of the staff.
I expect to see a accident the industry never seen before based on financially throttling maintenance, old age and obsolesce, widespread staff disillusionment and the neutered NRC. It is awful seeing the respected officials above you talking utter nonsense with the condition of the plant, the crazy new plant upkeep philosophy. You know these people are better than that. But you got to tow the party line.

This is getting really dangerous. That is a really bad accident if this occurs...you can certainly count on two or three known other component failures, maybe even poor training showing up, in this accident.

REACTOR TRIP DUE TO CYCLING OF TURBINE GOVERNOR VALVE
"At 2028 [EST] on January 3, 2019, with the reactor at 85% power, the reactor was manually tripped due to cycling of Turbine Governor Valve #4. The trip was uncomplicated with all systems responding normally following the trip. Investigation of the cause of the valve cycling is ongoing.
"All full-length control rods inserted fully. Auxiliary Feedwater System actuated as designed in response to low steam generator water levels. Operations stabilized the plant in Mode 3 (hot standby). Decay heat is being removed by atmospheric dump valves.
"This condition has no impact to the health and safety of the public.
"The licensee notified the NRC Senior Resident Inspector.
"This event is being reported pursuant to 10 CFR 50.72(b)(2)(iv)(B) and 10 CFR 50.72(b)(3)(iv)(A)."

POTENTIAL LOSS OF MSIV SCRAM FUNCTION DURING MAIN STEAM LINE ISOLATION VALVE TESTING
"At approximately 1040 EST on January 5, 2019, during evaluation of test results for the 'C' Main Steam Isolation Valve (MSIV), it was determined that closure of three of four
Main Steam Lines would not necessarily have resulted in a full scram during testing due to failure of a limit switch (LS-6) associated with MSIV-1C while in the test configuration. This condition is being reported as an eight-hour, non-emergency notification per 10 CFR 50.72(b)(3)(v), 'Any event or condition that could have prevented the fulfillment of the safety function of structures or systems that are needed to: (A) Shut down the reactor and maintain it in a safe shutdown condition.'
"The system was restored from the testing configuration at 1057 EST and the failed trip channel was placed in the tripped condition at 1326 EST thus restoring the design function. There was no impact on the health and safety of the public or plant personnel. The NRC Resident Inspector has been notified."

Entergy's Dog Plants Acting Up
What these guys got in common?
1) All on the way to permanent shutdown.
2) Unprofitable
3) Horrendous capacity factor problem.
3) Worst two plants in the USA.
Next Grand Gulf will have shutdown.
I could make the case these weak plants are steeling money from the other nuclear plants. This could knock a marginal good operating plant.
Pilgrim Powers Down Due to Faulty Valve
January 5, 2019
The Pilgrim Nuclear Power Station in Plymouth is yet again operating at sharply reduced capacity following as officials continue to deal with valve issues at the plant.
As of yesterday, the facility was working at 23% capacity as workers deal with the problem.
In a statement to CapeCod.com, Pilgrim spokesman Patrick O’Brien that the power reduction came as a result of prescheduled maintenance.
“Pilgrim is currently operating at reduced power due to a scheduled backwash of the main condenser,” he explained.
According to Pilgrim, backwashes are routine maintenance conducted 5-6 times annually to ensure safe and reliable operation of the main condenser by removing mussel growth.
During this power reduction officials at the plant will also be conducting other scheduled maintenance and testing, and would not indicate when they expect to return to full power.
Valves are responsible for regulating water flow into nuclear reactors, and keeping them fully operational has been a consistent issue at the Plymouth facility.
Similar valve issues have led to a number of unplanned shutdowns of the plant this year alone.
Pilgrim is set to permanently close in mid-2019.
Palisades reactor shut down Thursday night
COVERT — Palisades nuclear power plant operators manually shut down the reactor Thursday after fluctuations of a turbine governor valve.
“These types of valves control the flow of steam to the turbine,” Palisades spokeswoman Val Gent said.
The event happened just before midnight Thursday and was classified as a non-emergency.
Gent said all systems responded as expected during the shutdown.
The Nuclear Regulatory Commission reported that “all full-length control rods inserted fully. Auxiliary Feedwater System actuated as designed in response to low steam generator water levels.”
Gent said the plant is currently in a safe and stable condition and at no time was the health and safety of the public or plant challenged.
A detailed analysis of the cause and subsequent repair plan is underway.
Palisades returned to service Dec. 28 after a scheduled refueling and maintenance outage that began on Oct. 28. Only one more planned outage is scheduled before the plant is closed in spring of 2022.
