Pilgrim Nuclear Plant Shut Down, Their Own Switchyard Is The Problem, Entergy Assures Public No Immediate Danger

Pilgrim is a dangerous nuke plant.

they are arrogant, they know how they are screwing up, yet they refuse to take proper action.

per the NRC
Pilgrim's performance rating for “Unplanned Scrams (shutdowns) with Complications” was lowered following the third quarter of 2013. Then, in the fourth quarter of 2014, its performance rating for “Unplanned Scrams per 7,000 Hours of Operation” was also lowered. “Something that occurs if a plant has more than three such shutdowns during the designated period,” Sheehan explained.
The inspectors reported that while the company’s “problem identification, root cause evaluation and corrective action plans were adequate, it identified deficiencies in the implementation of corrective action plans, as well as in understanding of the issues’ causes."

The town it endangers is Plymouth.   most of the town didn't lose power but the Nuke Plant did.   one of that plants weaknesses is safe shutdown on loss of power, SCRAM.
 The plant has enough fuel onsite to run the emergency generators for 10 days

10 freaking days?   Are you kidding me?    In what event do you think a real emergency will happen?  Do you think infrastructure and fuel delivery services will be working just fine in such an event?

A commentor on the Boston Globe had this to say

Mr Rosen, I really don't understand why their power supply lines are so vulnerable. This is just a blizzard and not hurricane or tornado. When I looked at 7am on Nstar power outage map, Plymouth was experiencing power outage for 2% of its customers. I understand if 90% of Plymouth is down, but Pilgrim belongs to the 2% of most vulnerable electric customer within Plymouth? And they have 2 transmission lines into the plant and repeating the same issue they had in blizzard of 2013? Here is the incident report from 2013: http://www.nrc.gov/reading-rm/doc-collections/event-status/event/2013/20130211en.html#en48736. It says "The loss of offsite power is believed to be weather related. " They "believe"? They didn't bother to find out and repeat the same thing this year?

And a few more comments, damining Pilgrim:

This article has more reasonable theory that it could have caused by "Arcing in the plant’s switchyard". http://www.capecodonline.com/article/20150127/NEWS/150129438

If that is the case, it is more of the plant's issue rather than transmission line issue and it makes sense it is local issue to the plant. I found a NRC document describing exactly this issue for the plants along the ocean.

Information Notice No. 93-95: Storm-Related Loss of Offsite Power Events due to Salt Buildup on Switchyard Insulators

The above document has specific comment about Pilgrim.

"The 345 kV switchyard insulators at Pilgrim were coated with RTV silicon
rubber (Sylgard) in 1987. It was expected that the RTV coating, when applied
in 1987, would be effective for a period of 15 years. However, actual
experience at Pilgrim indicates that the coating is effective for a much .
shorter period of time. Consequently, the insulators at Pilgrim were cleaned
and coated with RTV again during the spring 1993 refueling outage. As a long-
term option, the licensee is considering a replacement of the existing 345 kV
switchyard with a modern compactly designed switchyard which would be more
resistant to the coastal environment. "

And a lot of people are waking up to the lies of Global Warming

OK lets start this discussion with something the failing nuclear industry hates to hear

There is no global warming, AND CO2 is only 3% responsible for warming that occurred earlier in last century.

These are fact, based on real data, and you can actually download the spreadsheets and see the chart derivations here.

Two years ago, during winter storm Nemo, the same two lines went down – one brought down by a tree, the other by ice. - See more at: http://plymouth.wickedlocal.com/article/20150131/NEWS/150139347#sthash.3m1RmN5N.dpuf
