The Polar Vortex Over Our Nuclear Plants?

update Jan 31

The is the second laterest nuclear facility in the USA. They are facing a permentant shutdown and everyone has been terrorizing the troops over this. 

Now the nuclear industry can't brag they were the superman over the polar vortex. This guy dropped in the polar vortex. What a disgrace. They should have had a employee manning the circ water trash screens. Waiting for the next one

Event Text
MANUAL REACTOR TRIP - CIRCULATING WATER ICING CONDITIONS

"At 0301 [EST] on 1/31/19, with Unit 2 in Mode 1 at 100% power, the reactor was manually tripped due to icing conditions requiring the removal of 4 Circulating Water Pumps from service. The trip was not complex, with all systems responding normally post-trip. 21 CFCU [Containment Fan Cooler Unit] was inoperable prior to the event for a planned maintenance window and did not contribute to the cause of the event and did not adversely impact the plant response to the trip. An actuation of the Auxiliary Feedwater System occurred following the manual reactor trip. The reason for the Auxiliary Feed Water System auto-start was due to low level in a steam generator. Operations responded and stabilized the plant. Decay heat is being removed by the Main Steam Dumps and Auxiliary Feedwater System.

"Due to the Reactor Protection System actuation while critical, this event is being reported as a four-hour, non-emergency notification per 10 CFR 50.72(b)(2)(iv)(B). This event is also being reported as an eight hour non-emergency notification in accordance with 10 CFR 50.72(b)(3)(iv)(A) as an event that results in a valid actuation of the Auxiliary Feed Water System. There was no impact on the health and safety of the public or plant personnel.

"The NRC Resident Inspector has been notified."

The icing condition was described as frazil ice.

Unit-1 reduced power to 88% because one circulating water pump was shutdown. 

***Can you imagine a big accident at any of these nuclear plants in this weather. Is the flex equipment qualified for -70 degrees"? At this time of the year, all these plants are supposed to be at 100%. 
Is the grid getting ready to collapse?
Why are some not? Can you even imagine battling at outside fire in these temps? Does the employees have the outside clothes for this kind of weather? Certainly these plants aren't designed for this kind of weather. Is a fire fightable in these conditions. 
Chicago Tribune: "Chicago grinds to a halt as polar vortex cold snap begins: 'Today's about as cold as it can get in Chicago".
I will be closely watching these guys for the next few days...
