Nuclear Energy Using New Momentum to Take on
Old Obstacles

BOSTON (AP) - Thanks to global warming, nuclear energy is hot again.
Its promise of abundant, carbon emissions-free power is being pushed
by the president and newly considered by environmentalists. But any
expansion won't come cheap or easy. The enormous obstacles facing
nuclear power are the same as they were in 1996, when the nation's
last new nuclear plant opened near the Watts Bar reservoir in
Tennessee after 22 years of construction and $7 billion in costs.
Waste disposal, safe operation and security remain major
concerns, but economics may be the biggest deterrent. Huge capital
costs combine into an enormous price tag for would-be investors.
There is also fervent anti-nuke opposition waiting to be re-stoked.
Jim Riccio of Greenpeace said nuclear advocates are exploiting global
warming fears to try to revive an industry that's too risky to fool
with.
"You have better ways to boil water," Riccio said.
But environmentalists aren't in lockstep on the issue. Bill
Chameides, chief scientist for Environmental Defense, said anything
that helps alleviate global warming must be an energy option.
"I think it's somewhat disingenuous that folks who agree that
global warming is such a serious issue could sort of dismiss it out of
hand," he said. "It's got to be at least considered."
The U.S. has 104 commercial reactors which supply about 20 percent
of the country's power. The Department of Energy projects a 45 percent
growth in electricity demand by 2030, meaning 35 to 50 new nuclear
plants will be needed by then just to maintain nuclear's share of the
energy market, said Scott
Peterson of the Nuclear Energy Institute, the industry's chief
lobbyist.
That growing demand, not global warming, "has been the single
biggest factor in companies looking at building large nuclear plants
again," Peterson said.
The Nuclear Regulatory Commission has been notified that several
companies will pursue licenses for up to 33 new reactors, with the
first one online in seven years at the earliest.
Earlier this year, projects at existing plants in Illinois and
Mississippi received permits for their proposed sites, but it's no
guarantee they'll be the first projects completed.
Many of the new plants are proposed in areas that already have
existing plants where there is more acceptance of nuclear energy.
President Bush visited one of those spots recently when he promoted
nuclear energy at the Browns Ferry's Unit 1 reactor in Alabama.
But any major expansion will require selling nuclear in new places,
where local opposition may be intense and winning approval may be
costly.
"This isn't just a bunch of environmentalists who think this is a
bad idea," Riccio said. "It's most people who aren't being paid to
think otherwise."
Nuclear power is produced when neutrons split the nucleus of
uranium atoms, releasing heat which is used to boil water and produce
the steam that drives a plant's turbines. The process is
emissions-free and the radioactive waste is contained inside the
plant.
The waste is currently stored at individual plants, awaiting
permanent transfer to the national Yucca Mountain Repository in
Nevada. But Yucca Mountain has faced stiff opposition and won't open
until the early 2020s at the earliest. By then, it will be too small
to hold the waste produced nationally.
Recycling used fuel, which contains 90 percent of its original
energy after one use, can reduce waste. "Reprocessing" also produces a
plutonium that's nearer to weapons grade, raising fears that
widespread reprocessing could increase the risks of nuclear
proliferation.
Nuclear energy critics also see the plants themselves as
devastating terrorist targets — "predeployed nuclear weapons," as Paul
Gunter of the anti-nuclear Nuclear Information and Resource Service
calls them.
While opponents fear catastrophe, money may be what kills a nuclear
revival. Peterson estimates each new plant will cost about $3 billion,
but the industry has a history of construction delays and cost
overruns.
The 2005 energy bill passed by Congress provides subsidies for the
first six plants, which the industry sees as a one-time "jump start,"
Peterson said.
"If we can't be competitive after those first few reactors, then
companies will stop building them," he said. "No one is building
nuclear plants because they have a religious belief in nuclear."
The industry hopes new standardized plant designs will help control
costs by taking advantage of cheaper, offsite modular construction.
Standardization could also allow plants to share parts and work crews,
Peterson said.
He said the new designs are also safer because they incorporate the
lessons of Three Mile Island, which had a partial meltdown in 1979
after workers misread a valve and mistakenly thought cooling water was
getting into the reactor.
The new systems have fewer valves and less piping, relying
primarily on gravity to deliver cooling water to the reactor.
Peterson said the industry has proven it can safely store its
waste, and will be able to do so until Yucca Mountain is open. Nuclear
plants also have elaborate security, including heavily armed guards
trained to deal with various attack scenarios, including multiple
truck bombings and suicide attack by wide bodied airplane, similar to
the Sept. 11 attacks, Peterson said.
Patrick Moore, a Greenpeace co-founder who's become a fervent
nuclear energy advocate and industry consultant, said the industry
needs to prepare for such worst case scenarios, but those shouldn't
drive the debate over nuclear energy.
Moore said his former environmentalist allies, some of whom now
deride him as a corporate shill, are stuck in a Cold War mentality
that lumps together the benefits and dangers of nuclear technology.
You don't ban the beneficial uses of a technology just because that
same technology can be used for evil," he said. "Otherwise we would
never have harnessed fire."
Chameides of Environmental Defense said he thinks nuclear power is
safe and that the waste problem has a technical solution, but he needs
convincing to endorse a nuclear resurgence. He's waiting to see the
industry move aggressively to address concerns about waste and
security. He's also skeptical the nuclear industry can survive without
continued subsidies, which he opposes.
"I'm a scientist not an economist," Chameides added. "I'm willing
to possibly be wrong."
