No to nukes
It's tempting to turn to nuclear plants to combat climate change, but
alternatives are safer and cheaper.
JAPAN SEES NUCLEAR POWER as a solution to global warming, but it's paying a
price. Last week, a magnitude 6.8 earthquake caused dozens of problems at
the world's biggest nuclear plant, leading to releases of radioactive
elements into the air and ocean and an indefinite shutdown. Government and
company officials initially downplayed the incident and stuck to the
official line that the country's nuclear plants are earthquake-proof, but
they gave way in the face of overwhelming evidence to the contrary. Japan
has a sordid history of serious nuclear accidents or spills followed by
cover-ups.
It isn't alone. The U.S. government allows nuclear plants to operate under a
level of secrecy usually reserved for the national security apparatus. Last
year, for example, about nine gallons of highly enriched uranium spilled at
a processing plant in Tennessee, forming a puddle a few feet from an
elevator shaft. Had it dripped into the shaft, it might have formed a
critical mass sufficient for a chain reaction, releasing enough radiation to
kill or burn workers nearby. A report on the accident from the Nuclear
Regulatory Commission was hidden from the public, and only came to light
because one of the commissioners wrote a memo on it that became part of the
public record.
The dream that nuclear power would turn atomic fission into a force for good
rather than destruction unraveled with the Three Mile Island disaster in
1979 and the Chernobyl meltdown in 1986. No U.S. utility has ordered a new
nuclear plant since 1978 (that order was later canceled), and until recently
it seemed none ever would. But rising natural gas prices and worries about
global warming have put the nuclear industry back on track. Many respected
academics and environmentalists argue that nuclear power must be part of any
solution to climate change because nuclear power plants don't release
greenhouse gases.
They make a weak case. The enormous cost of building nuclear plants, the
reluctance of investors to fund them, community opposition and an endless
controversy over what to do with the waste ensure that ramping up the
nuclear infrastructure will be a slow process - far too slow to make a
difference on global warming. That's just as well, because nuclear power is
extremely risky. What's more, there are cleaner, cheaper, faster
alternatives that come with none of the risks.
Glowing pains
Modern nuclear plants are much safer than the Soviet-era monstrosity at
Chernobyl. But accidents can and frequently do happen. The Union of
Concerned Scientists cites 51 cases at 41 U.S. nuclear plants in which
reactors have been shut down for more than a year as evidence of serious and
widespread safety problems.
Nuclear plants are also considered attractive terrorist targets, though that
risk too has been reduced. Provisions in the 2005 energy bill required
threat assessments at nuclear plants and background checks on workers. What
hasn't improved much is the risk of spills or even meltdowns in the event of
natural disasters such as earthquakes, making it mystifying why anyone would
consider building reactors in seismically unstable places like Japan (or
California, which has two, one at San Onofre and the other in Morro Bay).
Weapons proliferation is an even more serious concern. The uranium used in
nuclear reactors isn't concentrated enough for anything but a dirty bomb,
but the same labs that enrich uranium for nuclear fuel can be used to create
weapons-grade uranium. Thus any country, such as Iran, that pursues uranium
enrichment for nuclear power might also be building a bomb factory. It would
be more than a little hypocritical for the U.S. to expand its own nuclear
power capacity while forbidding countries it doesn't like from doing the
same.
The risks increase when spent fuel is recycled. Five countries reprocess
their spent nuclear fuel, and the Bush administration is pushing strongly to
do the same in the U.S. Reprocessing involves separating plutonium from
other materials to create new fuel. Plutonium is an excellent bomb material,
and it's much easier to steal than enriched uranium. Spent fuel is so
radioactive that it would burn a prospective thief to death, while plutonium
could be carried out of a processing center in one's pocket. In Japan, 200
kilograms of plutonium from a waste recycling plant have gone missing; in
Britain, 30 kilograms can't be accounted for. These have been officially
dismissed as clerical errors, but the nuclear industry has never been noted
for its truthfulness or transparency. The bomb dropped on Nagasaki contained
six kilograms.
Technology might be able to solve the recycling problem, but the question of
what to do with the waste defies answers. Even the recycling process leaves
behind highly radioactive waste that has to be disposed of. This isn't a
temporary issue: Nuclear waste remains hazardous for tens of thousands of
years. The only way to get rid of it is to put it in containers and bury it
deep underground - and pray that geological shifts or excavations by future
generations that have forgotten where it's buried don't unleash it on the
surface.
No country in the world has yet built a permanent underground waste
repository, though Finland has come the closest. In the U.S., Congress has
been struggling for decades to build a dump at Yucca Mountain in Nevada but
has been unable to overcome fierce local opposition. One can hardly blame
the Nevadans. Not many people would want 70,000 metric tons of nuclear waste
buried in their neighborhood or transported through it on the way to the
dump.
The result is that nuclear waste is stored on-site at the power plants,
increasing the risk of leaks and the danger to plant workers. Eventually,
we'll run out of space for it.
Goin' fission?
Given the drawbacks, it's surprising that anybody would seriously consider a
nuclear renaissance. But interest is surging; the NRC expects applications
for up to 28 new reactors in the next two years. Even California, which has
a 31-year-old ban on construction of nuclear plants, is looking into it.
Last month, the state Energy Commission held a hearing on nuclear power, and
a group of Fresno businessmen plans a ballot measure to assess voter
interest in rescinding the state's ban.
Behind all this is a perception that nuclear power is needed to help fight
climate change. But there's little chance that nuclear plants could be built
quickly enough to make much difference. The existing 104 nuclear plants in
the U.S., which supply roughly 20% of the nation's electricity, are old and
nearing the end of their useful lives. Just to replace them would require
building a new reactor every four or five months for the next 40 years. To
significantly increase the nation's nuclear capacity would require far more.
The average nuclear plant is estimated to cost about $4 billion. Because of
the risks involved, there is scarce interest among investors in putting up
the needed capital. Nor have tax incentives and subsidies been enough to
lure them. In part, that's because the regulatory process for new plants is
glacially slow. The newest nuclear plant in the U.S. opened in 1996, after
having been ordered in 1970 - a 26-year gap. Though a carbon tax or carbon
trading might someday make the economics of nuclear power more attractive,
and the NRC has taken steps to speed its assessments, community opposition
remains high, and it could still take more than a decade to get a plant
built.
Meanwhile, a 2006 study by the Institute for Energy and Environmental
Research found that for nuclear power to play a meaningful role in cutting
greenhouse gas emissions, the world would need to build a new plant every
one to two weeks until mid-century. Even if that were feasible, it would
overwhelm the handful of companies that make specialized parts for nuclear
plants, sending costs through the roof.
The accelerating threat of global warming requires innovation and may demand
risk-taking, but there are better options than nuclear power. A combination
of energy-efficiency measures, renewable power like wind and solar, and
decentralized power generators are already producing more energy worldwide
than nuclear power plants. Their use is expanding more quickly, and the
decentralized approach they represent is more attractive on several levels.
One fast-growing technology allows commercial buildings or complexes, such
as schools, hospitals, hotels or offices, to generate their own electricity
and hot water with micro-turbines fueled by natural gas or even biofuel,
much more efficiently than utilities can do it and with far lower emissions.
The potential for wind power alone is nearly limitless and, according to a
May report by research firm Standard & Poor's, it's cheaper to produce than
nuclear power. Further, the amount of electricity that could be generated
simply by making existing non-nuclear power plants more efficient is
staggering. On average, coal plants operate at 30% efficiency worldwide, but
newer plants operate at 46%. If the world average could be raised to 42%, it
would save the same amount of carbon as building 800 nuclear plants.
Nevertheless, the U.S. government spends more on nuclear power than it does
on renewables and efficiency. Taxpayer subsidies to the nuclear industry
amounted to $9 billion 2006, according to Doug Koplow, a researcher based in
Cambridge, Mass., whose Earth Track consultancy monitors energy spending.
Renewable power sources, including hydropower but not ethanol, got $6
billion, and $2 billion went toward conservation.
That's out of whack. Some countries - notably France, which gets nearly 80%
of its power from nuclear plants and has never had a major accident - have
made nuclear energy work, but at a high cost. The state-owned French power
monopoly is severely indebted, and although France recycles its waste, it is
no closer than the U.S. to approving a permanent repository. Tax dollars are
better spent on windmills than on cooling towers.
