Down, up, down again: Arkansas Nuclear One

Entergy announced August 8th that its Arkansas nuke was back up

after a man died there in March, but it only made it to 87% power
on August 12th and then back to zero yesterday.
There’s no NRC event for yesterday’s downtime: what’s going on?
Meanwhile, the dead man’s family is suing Entergy, and Entergy
is suing its contractors.
Sounds like the Plant Vogtle circular firing squad.

Entergy restarts Unit 1 at Arkansas Nuclear One power plant,

Prior to restart, the unit needed an extensive restoration,
including damage evaluation, repairs to non-nuclear plant components
and rescheduling its refueling activities.

The restoration was made compulsory following the collapse of a
contractor’s crane on 31 March 2013, while shifting a generator
stator out of the turbine building.

Hm, “made compulsory” by whom?
NRC?
OSHA, which
also investigated?
Arkansas?
Other? Continue reading →

Pilgrim nuke down because of cold, heat, leak: when does it ever run?

Down in

January, February, April,

May, running low March and June,
and now likely to go down because of summer heat,
under what conditions does Entergy’s Pilgrim nuke near Boston, MA like to run?
Entergy also couldn’t keep the power on during the Super Bowl
and

still has Arkansas Nuclear 1 down since a fatal accident in March.
To be fair,

many nukes can’t handle heat.
Remind me,

why are we building more of them?

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 →
