Subject: Lochbaum on Limerick Dropped Fuel
Crew Drops Fuel Rods at Limerick, Pa., Nuclear Power Plant By Dawn
Fallik,
The Philadelphia Inquirer -- Feb. 6
Two bundles of new fuel rods were damaged last week when workers at the
Limerick nuclear station neglected to ensure that the rods were
strapped down, officials from the Nuclear Regulatory Commission said
yesterday. No workers were injured in the Jan. 29 incident and there
was no radioactive release, said Neil Sheehan, an NRC spokesman. The
event will be documented as part of a larger inspection report but
there will not be a separate investigation, he said.
New fuel rods, about 12 feet long and about the same diameter as pencil
erasers, are not radioactive in the same way as used fuel. Holding them
would result in a mild sunburn, said David A. Lochbaum, a nuclear
safety engineer for the Union of Concerned Scientists.
[ False. The dose rate at the surface of a UO2 assembly is on the
order of 0.25 millirem/hr (1). It takes on the order of 300 Rem
*acute* dose to cause erythema (2). Not to mention that nuclear plant
workers are limited to 5 REM per year unless they are protecting life
or property.

"If you're going to drop a fuel rod, that's the time to drop it," he said.
The rods did not break but the metal frame holding them in place was
damaged, Limerick spokeswoman Lisa Washak said. Each bundle weighs
about 700 pounds and holds around 100 fuel rods. The plant receives
the fuel from General Electric in Wilmington, Washak said.
"There's some slight damage, but we'll be sending them back as a
precaution," Washak said. "They won't be used in the generator." She
said that each bundle costs about $200,000.
The utility immediately called for a cessation, or stand-down, of
fuel-handling activities until the cause of the event was determined,
Sheehan said.

Thanks for your photo, John (uploaded to the "accidents" section of the
photos). I was rather taken back by the statement in the article.
Could be a press misquote, but I doubt they'd come up with it entirely
by themselves. What I'm really curious about is if Dave will attempt
to correct the orders-of-magnitude error. Shoot, even when Norm
teaches me something in a Yahoo Group (as he's done like two times), I
say "Thanks for the correction. I apologize for my error and will not
repeat it."
Regards,
Jim
