RUSSELLVILLE, Ark. (KTHV) - Entergy released the following statement Sunday regarding an accident at Arkansas Nuclear One in Russellville earlier that morning.

"A significant industrial accident occurred at Arkansas Nuclear One at approximately 7:45 a.m.

There has been one confirmed fatality and three additional injuries. The injured employees have been transported to a nearby hospital.

The accident occurred when a generator stator fell as it was being moved out of the turbine building. Unit 1 is in a refueling outage and Unit 2, which was operating at full power, automatically shut down. Both plants are in a stable shutdown condition and there is no danger to the public.

The plant is in an unusual event classification, the lowest of four emergency classifications designated by the Nuclear Regulatory Commission. Additional staff has been brought to the site to manage the situation.

Jeff Forbes, executive vice president and chief nuclear officer said, "We are deeply saddened by what has happened today. Our greatest sympathy is with the family and friends of the employee who lost his life, and with those who sustained injuries. I also want to express my sorrow and support to all those who work at Arkansas Nuclear One. I know this is especially hard on them."

At this time, the full extent of structural damage on Unit 1 is not known. There was one known fatality and 4 known serious injuries to workers. The local coroner is on site for the fatality and the injured personnel have been transported offsite to local hospitals. Investigation into the cause of the failure and extent of damage is ongoing.

On Unit 2, all rods inserted during the trip. The core is being cooled via natural circulation. Decay heat is being removed via steam dumps to atmosphere. There is no known primary to secondary leakage.

* * * UPDATE FROM DAVID THOMPSON TO HOWIE CROUCH AT 1934 EDT ON 3/31/13 * * *

The licensee terminated the NOUE at 1821 CDT. The basis for termination was that the affected bus (2A2) is de-energized and no other equipment on Unit 2 was damaged.

The licensee has notified the state and local authorities and will be notifying the NRC Resident Inspector.

Notified R4DO (Pick), NRR EO (Howe), IRD (Gott), DHS SWO, DHS NICC, FEMA and Nuclear SSA (via email).

Wow, Arkansas had the Exxon oil spill on Friday March 29, 2013 and then on Sunday March 31, 2013 the Arkansas Nuclear One accident happens only about 50 miles from each other!

You should ask your health department official to make a public retraction for the lie he made in his statement.

Quote:
There was no nuclear release of any kind,” said Ed Barham, spokesman for the Arkansas Health Department.


http://rt.com/usa/arkansas-nuclear-plant-accident-170/

Normal operations of a nuclear reactor running releases what the EPA believes are small amounts of radioactive releases, but even more during an EMERGENCY SHUTDOWN! Then there were "atmosphere releases" aka venting dumps done on top of that and this guy has the nerve to publicly lie to the public.

SHAME ON YOU Ed Barham! :evil:

PRELIMINARY NOTIFICATION OF EVENT OR UNUSUAL OCCURRENCE -- PNO-IV-13-002
This preliminary notification constitutes EARLY notice of events of POSSIBLE safety or public
interest significance. The information is as initially received without verification or evaluation,
and is basically all that is known by the Region IV, Arlington, Texas, staff on this date.
Facility
Arkansas Nuclear One, Units 1 and 2
Entergy
Russellville, Arkansas
Dockets: 05000313; 05000368
License Nos. DPR-51; NPF-6
Licensee Emergency Classification
X Notification of Unusual Event
Alert
Site Area Emergency
General Emergency
Not Applicable
SUBJECT: ARKANSAS NUCLEAR ONE, UNIT 2, NOTIFICATION OF UNUSUAL EVENT
DESCRIPTION:
On March 31, 2013, at approximately 7:50 a.m. (CDT), Arkansas Nuclear One (ANO), Unit 1
which was in a refueling outage, lost offsite power and ANO Unit 2 experienced a reactor trip
after a 600 ton generator stator fell onto the turbine deck and then approximately 30 feet onto
the train bay floor. The electrical non-vital busses supplying offsite power to Unit 1 were
damaged, and some of the fire suppression system piping was damaged. The falling stator and
crane components caused the supply breaker to Unit 2 reactor coolant pump B to open. The
loss of reactor coolant pump B resulted in a Unit 2 reactor trip, which had been operating at 100
percent power. Both units are stable and remain shutdown.
The licensee reported that one worker was killed and eight others were injured when the main
generator stator fell. Seven workers have been treated and released from a hospital, while one
remains hospitalized.
With the loss of offsite power to Unit 1, both Unit 1 emergency diesel generators (EDGs) started
and loaded onto their electrical busses. Decay heat removal was quickly restored. The Unit 1
emergency diesel generators continue to supply power to the vital electrical busses.
At 9:22 a.m. (CDT), offsite power to Unit 2 from startup transformer 3 was lost because water
from a fire main caused a short circuit. ANO Unit 2 EDG 2 started and energized the train B
vital electrical bus, while train A vital and non-vital electrical busses were re-energized from
startup transformer 2. The supply breaker from startup transformer 3 failed because of water
intrusion stemming from damaged fire suppression system piping. Operators cooled down
Unit 2 to hot shutdown.
At 10:44 a.m. (CDT), the licensee declared a Notification of Unusual Event because the failure
of the supply breaker may have been caused by an explosion in the breaker cubicle. The event
was terminated at 6:21 p.m. because the affected electrical bus was not energized and there
was no other damage. The fire suppression system to ANO Unit 1 is shutdown due to the
damage to the fire water system piping. Damaged portions of the ANO Unit 2 fire protection
system have been isolated. Additional fire water pumps have been positioned to provide fire
water if necessary. The licensee has established fire watches in the auxiliary buildings of both
units.
PNO-IV-13-002 -2-
The licensee informed the State of Arkansas Department of Health of the Notification of Unusual
Event at 10:48 a.m. (CDT).
The licensee has issued a press release.
The NRC resident inspectors responded to ANO, and are monitoring the licensee’s actions.
Two additional inspectors were dispatched to the site.
The Region IV office received initial notification of this occurrence by telephone from the Senior
Resident Inspector on March 31, 2013, at 8:25 a.m. (CDT). This information presented herein
has been discussed with the licensee and is current as of 5:30 p.m. (CDT) on April 1, 2013.
CONTACTS:
Don Allen, Branch Chief, 817-528-3439
Fred Sanchez, Senior Resident Inspector, ANO
ADAMS ACCESSION NUMBER: ML13092A024

Interesting how one problem turns in to another problem. After the first problem started at 7:50 a.m. (CDT) they should have shutdown all reactors onsite just to be safe. This would have avoided the need to later do an EMERGENCY hot shutdown of reactor Unit 2 and the added tritium and other higher levels of radioactive stuff released during an EMERGENCY SHUTDOWN aka "HOT" vs. a normal slow shutdown.

Looking back at hurricane Sandy and Oyster Creek Nuclear Plant, they should have shutdown the nuclear plants in the hurricane path just to be safe. It's like slowing down when driving around a curve. We could drive fast through curves and might not have any problems, but if we drive a little slower through the curve our risk of problems are clearly less.
