Getting Off Our Nuclear Power Fixation

My favorite internet date site posits a question: "What is the
best/worst lie you've told?"
* "I've never seen that man before in my life."
* "I've had a vasectomy."
* "I know what I'm doing."
* "I'm not married."
* "Nuclear power is clean and safe."
I made that last one up. But if the power industry and the federal
government had their profiles up on that website, that would be their
answer.
Despite Vice President Dick Cheney's contention that nuclear power is
"carbon-free," nukes contribute to the greenhouse effect. The
government is betting billions of dollars of our money, and could
simply give it away to developers to build new nuclear plants. And,
our country's aging nuke fleet is getting plastic surgery while its
innards decay and get ever closer to fatal accidents.
Let's start with the greenhouse lie. Instead of coal or natural gas,
nukes run on uranium. Like coal, uranium has to be mined. It also has
to be converted, enriched and transported. Add that up and you get
more greenhouse gas emissions than a natural gas-fired power plant,
according to one of the few studies done on the complicated issue by
the scientists at the German Oko-Institut. Meanwhile, the nuclear
industry would have you believe that solar and wind power create more
greenhouse gases than nuclear.
Not only does nuclear power contribute to the greenhouse effect, and
so, indirectly affecting the planet's health and your well-being, it
very well could affect your health and the planet's health directly
-- by killing everything in sight in an accident.
This is how nuclear energy works on a basic physics level. When atom
of a special type of element, uranium 235, is bombarded by neutrons,
the uranium releases more neutrons that split more uranium atoms in a
chain reaction. This is fission. Nuclear power plants use the heat
given off from that process to boil water. The steam from that water
turns the same basic turbines that you find in other power plants
fueled by natural gas or coal to make the heat. It's a huge, scary
engineering problem just meant to boil water. As antinuclear guru
Amory Lovins quipped, it's like using a chainsaw to cut butter.
The difference is the radioactivity is contained -- at least we hope
it remains contained -- within the reactor where the fission is
constantly exploding at a molecular level. If that radioactivity
escapes the reactor (that happens on occasion) or is released through
contaminated water spills (that happens with great regularity), then
it's a health and safety problem.
The thing about deadly radioactivity is that you can't see it coming.
You can't smell it. You can't feel it until it's too late.
On a basic physiology level, when radioactivity is absorbed by a
body, it wreaks havoc on DNA molecules. Studies show ingested and
inhaled uranium emissions may affect babies in the womb and increase
risk of cancers such as leukemia. It may damage chromosomes. In high
concentrations, it kills immediately.
That's not a problem, according to the government, because no matter
how complicated it gets to boil water to make electricity, there
won't be any accidents. The chief federal nuclear regulator, Nils
Diaz, chair of the Nuclear Regulatory Commission, said in April that
the agency is "ensuring safety in the civilian uses of nuclear
materials."
The government/industry's plan is to contain all that nasty, deadly
fission by building a huge box around it. The boxes, the reactor
vessels, are made of thick carbon steel, lined with stainless steel.
"That oughta keep 'er," some engineer figured. After decades of
operation, though, it doesn't. The lesson happened in 2002 when the
Davis-Besse nuclear plant's reactor head was found to have been worn
away -- from a two-feet-thick exterior to a 3/8-inch layer of
stainless steel. Even that last bit had bubbled outwards from the
pressure of keeping radioactive action on the inside. The plant, near
Toledo, Ohio, had a hole in its reactor head wide enough and deep
enough to put a fist into, according to former Nuclear Regulatory
Commission member Victor Gilinsky. Corrosion on that part reduced the
head by 70 pounds of steel. Workers found the problem inadvertantly,
leaving the reactor perilously close to unleashing a jet of
radioactive steam from the pressurized vessel.
Then there's the continuing safety and health risks of old nukes --
the kind, like Nine Mile Point in New York, or Hatch, in Georgia,
that might be in your own backyard. You don't hear much about them,
but on any given day there are two or three "incidents" at reactors
across the country serious enough to report to the government, and
often serious enough to cause the reactor to shut down.
Like humans, the older the plants get, the more things go wrong. A
steam generator replacement, like grandma's hip replacement, only
buys so much time. The reactor's steel, like human bones, gets more
brittle with age. For a price, plant owners can give their nuclear
facilities the equivalent of bone replacements, organ transplants,
face lifts and tummy tucks, but what they will still have in the end
is an old nuclear plant.
In engineering parlance, this is called the "bathtub" curve. When new
nuclear plants start out expensively fussy, their kinks aren't worked
out and they are prone to accidents. As they mature, they tend to run
with fewer problems. In middle age, they are at the bottom of the
bathtub, running relatively inexpensively along with little input
other than maintenance and fuel. When they age, though, they begin to
climb the curve of the bathtub -- with risks and costs increasing.
When the industry and regulators refer to their safety records for
the last 25 years, they are pointing to the low water line at the
bottom of the bathtub.
We can only hope the industry is correct when it claims that it can
keep these aging plants from accidents that cause radioactive
release. And yet, as they approach the end of their original 40-year
licensed lives, nuclear power plant owners across the nation have
applied for 20-year license extensions. The Nuclear Regulatory
Commission has approved 42 extensions -- nearly half the nation's
nuclear power plants.
There's health problems. There's safety problems. Then, there's money.
Even though relatively warm, fuzzy and uncomplicated renewable energy
developers are pounding at the government's door, the feds are so set
on building new nuclear reactors that they're simply giving away
money to the industry.
Lawmakers who crafted the 2005 Energy Policy Act (EPAct) are on a
mission to get new nukes built. They've devised a plan so the
financial risk -- and perhaps the entire cost -- of new nuclear
plants may be completely borne by taxpayers.
The incredible deal under EPAct the nuclear industry got for new
nukes includes giving the Department of Energy broad authority to
underwrite loans to build nuclear plants with no limit on the number
of projects or total principal that could be guaranteed, according to
a Congressional Budget Office. It also allows the government to take
over a loan and make payments on behalf of borrowers prior to a
default. "Such payments could result in DOE effectively providing a
direct loan with as much as a 100 percent subsidy rate -- essentially
a grant -- that could be used by the borrower to pay off its debts,"
according to the budget office. DOE's money is, however, our money.
These days, most of us have a personal choice in our economic
behavior. We can spend a few more cents on recycled toilet paper or
organic food, knowing that, in the long run, we are doing something
to help prolong our environment.
When it comes to energy, few of us have any personal choice unless we
can afford to install solar power for our homes and businesses. None
of us can sort out which electrons come from nuclear power when we
plug our computers or toaster. If we want to get rid of this
dangerous technology; if we don't want to be responsible for more
deaths, not to mention the danger to life and habitat in the event of
an accident; if we don't want to bankrupt our own pockets as well as
our state's funds by pursuing the massive expense of continuing
nuclear power, then we have to influence policymakers.
Getting rid of nuclear power cannot be accomplished on a personal,
everyday consumption level. Yet on a personal level, we can make it
clear to politicians that this is an issue that can't be ignored.
Nuclear waste remains lethal for about a quarter of a million years.
It is not going to go away for a very, very long time. It could
bankrupt us all. Policymakers must prevent license extensions on a
legal level. States must fight to regain their rights over
environmental and economic decisions when it comes to nuclear power.
It won't be easy, but hell, it's worth your DNA, your safety, your life.
