Leonard vs. The Atom
(Or, am I all aglow?)
January 5, 2000, article two
Here's a question. How much radiation would a person
be exposed to if he or she spent five hours exploring the Davis-Besse
nuclear power plant?
I found out for myself on Nov. 20, courtesy of Randy
Burk, a local Boy Scout leader and a plant operator at Davis-Besse.
Randy conducted a tour for some Findlay high school students
and allowed me to tag along.
After the kids were finished, we returned to the plant
to view some other areas of the plant.
First of all, it's worth knowing that according to the
Nuclear Regulatory Commission, 5,000 millirems of radiation annually
is the maximum allowable for a nuclear plant worker.
Randy has never received more than 250 in a year.
How bad is 250? Each and every one of us receives 293
millirems annually from naturally occurring "background" radiation.
Why? Because many elements we come into contact with
every day give off harmless amounts of radiation. Think about that the
next time you fire up your toaster.
Anyway, before entering some of the more sensitive areas,
I had to wear a dosimeter.
A technician put the dosimeter in a computerized sensing
device to make sure its initial reading was set to "zero."
Then it was off to see about as much of Davis-Besse as
you can see without actually going in the containment building itself
which houses the reactor vessel.
We climbed around more pipes, valves, meters, switches
and pumps than you've ever seen in one place in your life.
At one point, we were standing right next to the containment
building while Randy explained one of the emergency safety valves that
would open automatically in an emergency so water could be pumped into
the reactor.
He also showed me the spent fuel storage pool. We stood
about 10-15 feet away from the edge. I could look down and see the old
fuel assemblies, still radioactive under 23 feet of continuously recirculating
water laced with boron.
When we were finished, I had to pass through a radiation
detector, just as the employees do.
"Inset right arm" it flashed. I inserted my right arm.
"Counting right side," it continued. I waited patiently.
"Right side okay," it announced.
"Oh, rapture," I sighed. I had to repeat the procedure
for my left side.
"You may pass," blinked the detector. I felt like a new
man.
Then I turned in my dosimeter to the technician who put
in the computer to see if I picked up any stray radioactivity missed
by the detector. He gave me a form with the results.
Initial reading = zero. Visitor individual exposure =
zero.
So there I spent all that time in close proximity to
all that atomic fissioning and I didn't get plunked by even one loose
neutron.
What's more, I have my very own form (DP-HP-01204) to
prove it.
