More Than Bad Seals At Indian Point Three

 "out of an abundance of caution,”

If this was true, why didn't they shutdown the very minute they confirmed inner seal leakage?

They probably stalled to get thru summer peak, and have new seals made up, and get W contractor to install them.

And the irony, and the prep and disassemble, and how long will it really take to take out the old seals and install the new one, 1 - 4 hrs.
Penny wise and pound foolish.

Watching the parade of scrams and shutdowns walk pass us from the Indian Point Facility.

It is highly abnormal to have reactor head seal problem...it worst than that when they both go.
Outage planned for Indian Point reactor after water leaks

Indian Point Energy Center operators planned a shutdown of the Unit 3 nuclear reactor beginning Sept. 14 to replace lid seals that have been leaking for weeks.

The leakage occured between the inner and outer seals separating the lid and vessel of the reactor. The replacement is “out of an abundance of caution,” according to a statement from Entergy Corp., owners of the Buchanan-based power plant.

Jerry Nappi, a spokesman for Entergy, said the inner seal was observed to be leaking shortly after the unit’s planned refueling outage in March and the outer seal began leaking in July.

Operators responded by setting up a water collection line and a tank, Nappi said, adding plant workers “were able to closely track [the leak] and monitor it continuously from the control room.”

The water leak did not pose any threat to the health and safety of workers or the public and there was no radiation released, according to Entergy.

The work to replace the seals requires help from a specialty vendor and Entergy had to coordinate schedules to plan the outage. Nappi said the work is expected to take two weeks.
Amazing bad number!!! It's money.
This is the sixth time the Unit 3 reactor has shut down this year and, of those six, the second time the reactor went offline for planned maintenance. The four other times Unit 3 went offline were unexpected automatic or manual shutdowns for a pipe leak, transformer failure, electrical disturbance and fluctuating water levels.
Beating the hell out of the plant and safety systems...abusing them.

Recent series of Indian Point shutdowns worst in years

Besides a transformer failure that spilled oil into the Hudson River, this year's shutdowns were due to a steam leak, a pump motor failure and switch yard breaker failure

BUCHANAN — Four unplanned reactor shutdowns over a two-month period at Indian Point are the most setbacks the nuclear power plant has experienced in years.

A review of unplanned shutdowns from January 2012 to the present showed this year's events happened within a short time frame, between May 7 and July 8, in contrast with events from other years that were more spread out, according to data released by Indian Point.

So many mishaps at the Entergy-owned plant haven't occurred since 2009, when one of two units at the Buchanan site experienced a similar series, said plant spokesman Jerry Nappi.

Besides a
May 9 transformer failure that spilled some 3,000 gallons of oil into the Hudson River, this year's shutdowns were prompted by a May 7 steam leak, a July 8 pump motor failure and a June 15 switch yard breaker failure offsite in a Consolidated Edison substation.

If a nuclear plant has more than three unplanned shutdowns in a nine-month period, its performance indicator could be changed by the federal Nuclear Regulatory Commission, which results in additional oversight. That's what happened with Entergy's Pilgrim Nuclear Power Station in Plymouth, Mass., after four unplanned shutdowns in 2013.

So far, Entergy said there doesn't appear to be a pattern to the Indian Point shutdowns.

"You do want to look at these events holistically to see if there is something in common, but you also look individually to see what the causes were," Nappi said. "A plant shutdown in and of itself is not a safety issue."

One of the four recent Buchanan shutdowns triggered a special inspection by the NRC and calls to close the nuclear plant by environmental groups and elected officials. Gov. Andrew Cuomo has said in the past Indian Point should close, but his office did not respond to a request for comment about whether the recent shutdowns have prompted any state scrutiny.

The NRC is expected to release a quarterly report on Indian…
