Arkansas Nuclear 1 still down since fatal accident in March

Apparently we still don’t know why this happened:



At approximately 7:50am on Sunday, March 31, 2013, a 600-ton
generator stator fell onto the turbine deck and then about 30 feet
to the train bay floor as was being lifted out of the Unit 1 turbine
building at the Arkansas Nuclear One plant. One worker was killed
and four others injured when the load fell.

Fission Stories #139: Arkansas Nuclear One Fatal Event,

The

NRC reviewed U.S. nuclear plant experience with lifting loads
with cranes between 1968 and 2002. The NRC reported that about two
load drops per year happened during this period with ten incidents
causing deaths. The NRC’s review concluded that there had been only
three very heavy load drops (defined as a load weighing more than 30
tons). ANO-1 makes four.

While accidents can also happen with wind turbines or even
installing solar panels on rooftops,
a single solar or wind accident doesn’t Continue reading →

Korean nuke supplier for Plant Vogtle forged documentation for “a host of nuclear reactors”

Korea’s Doosan supplied that
that train-wrecked Plant Vogtle reactor vessel later

left unprotected sitting at Savannah port,


as well as parts for more than a dozen U.S. reactors.
And Doosan, according to the Korean government,
forged documentation that just shut down “a host of nuclear reactors”
in Korea, whose Prime Minister said,

“Those found to be involved in wrongdoing or corruption must be
sternly punished by the law, regardless of their rank and status.”

According to World Nuclear News 5 June 2008,

Nuclear reactor percent power from NRC data

Do nuclear reactors really deliver dependable baseload capacity?
I hear industry execs say 99.99% uptime.
The real average from seven years of NRC data for 104 reactors is 88.13%.


Vogtle 1
According to Power Reactor Status Reports
posted online by the Nuclear Regulatory Commission,
here are the actual percent power percentages over time
for the 104 listed nuclear power reactors.
The timeframe is 31 March 2006 through today, 21 May 2013.
(The NRC data appears to go back to 1999, but seven years
is a good sample to start with.)
The computation for each reactor is the sum of the uptime
percentages for each day divided by the number of days.
The total uptime is the sum of the reactor uptimes divided
by the number of reactors.
Here’s the list, sorted two ways:

Vermont Yankee may be next nuke to close



UBS predicts Entergy will close its Vermont Yankee nuclear power plant soon:
that’s the same Entergythat couldn’t keep the power on during the SuperBowl
and that

can’t keep Pilgrim 1 nuclear reactor up in Massachusetts during a winter storm
(down 3 days now, for the third downtime in a month).
A few days later, UBS
set Entergy up on a quarterly earnings call to mention that
Vermont Yankee had already been taken off the New England energy
capacity auction, which would make it easy to replace.

San Onofre still down in California,

Dominion Power closing Kewaunee in Wisconsin,

NRC terminated Calvert Cliffs in Maryland,

Duke closing Crystal River in Florida,
and maybe Vermont Yankee next?
How about

we pass HB 267 to stop Georgia Power charging for cost overruns
for Vogtle 3 and 4 and see how long before Southern Company stops that project?

Andrew Stein wrote for vtdigger 6 February 2013 (updated 7 Feb),

In report, financial firm forecasts that Entergy may close Vermont Yankee,

In an investment research letter, the Swiss financial services
company UBS Securities anticipates Entergy Corp. will retire one of
its nuclear power plants in 2013, and it cites “Vermont Yankee
as the most tenuously positioned plant.”



UBS representatives met with Entergy’s new leadership team on Feb.
1, the same day Leo Denault became CEO and chair of the board for
the Louisiana-based company that operates the Vermont Yankee nuclear
power plant.

And that’s how a clean-broom new CEO often signals his intentions:
by bringing in outside experts to provide him cover for what he
already intends to do anyway.
And this new-broom CEO

is Entergy’s former Chief Financial Officer
who as CFO has repeated fiddled with Vermont Yankee to try to
make it less unprofitable.
What did those experts say?

Pilgrim nuke shut down in winter storm again this weekend



Entergy, the company that blacked out the Super Bowl,
now has taken down Massachusetts’ Pilgrim nuclear reactor
in a winter storm.
And that’s not the first time this year.
Plus, what will happen with sea level rise to that nuke on the coast?

Beth Daley wrote for Boston.com this morning,

Pilgrim nuclear plant shuts down in storm,
Pilgrim Station nuclear plant automatically shut down in the thick of the storm Friday night after losing power, according to a statement by Entergy, the plant’s owner.

Authorities said there is no danger and backup diesel generators are
powering safety systems.

“The plant is in a safe, secure condition and will remain on backup
power supply until off-site power is restored,” the statement said.

But that’s hardly the whole story.
Pilgrim Station has been down about a week lately, and at 80%
still other days, according to the

Nuclear Regulatory Commission (NRC):

Nuclear reactors near here

If you think of nuclear reactors as something far away,
or as much safer than Fukushima,
you’re in for a surprise.
The most notorious reactors are the ones not yet built,
units 3 and 4 at Plant Vogtle near Augusta and their

famous financial boondoggle.
But others are closer, older, and more numerous than you may know.

Here’s a map by the Nuclear Regulatory Commission (NRC).
