The Sun, The Wind and Nuclear Power?
By Dan Whipple, United Press International
BOULDER, Colo. (UPI) -- The suggestion that nuclear
power might be the best available option for easing
greenhouse gas emissions sends conservationists into
tortured simile. The Sierra Club's Brendan Bell told
United Press International, "Switching to nuclear
power from coal-fired power to help the environment is
like running to McDonald's to lose weight."
Likewise, Paul Gunter, director of the reactor
watchdog project for the Nuclear Information and
Resource Service, told UPI it would be like
prescribing heroin to help someone quit smoking. At a
certain level of examination, however, nuclear power
can make a pretty strong environmental argument.
Bernard L. Cohen, in his 1990 book, "The Nuclear
Energy Option," estimated deaths from the entire
nuclear fuel cycle were about 0.3 per gigawatt of
energy produced per year. Whereas, Cohen continued, a
single, 1,000-megawatt coal-fired power plant causes
25 fatalities, 60,000 cases of respiratory disease,
$12 million in property damage and nitrogen oxides
emissions equivalent to driving 20,000 cars each year.
Cohen, a professor emeritus of Physics and of
Environmental and Occupational Health at the
University of Pittsburgh, said he concluded that
nuclear power is more than 1000 times better than coal
burning, based on the number of deaths caused. Even
solar power is ten times worse than nukes, he said,
based on the coal burning required to produce the
materials. The problem with nuclear is twofold "Waste
and transportation are the biggest issues," said Bell,
a conservation assistant in the club's global warming
program.
The Yucca Mountain waste repository in Nevada is
scheduled to go on line in 2010 and begin taking in
the spent reactor fuel now being stored at temporary
sites around the country. That waste will have to be
isolated from the environment for about 20,000 years
-- much longer than human civilization has lasted up
to now -- a challenge even usually confident engineers
and administrators admit is daunting. Early in its
history -- back in the 1950s, when it was advertised
as
producing electricity "too cheap to meter" -- many
environmental groups endorsed nuclear power. But they
got over it, and at the moment none show any
indication of reviving their enthusiasm.
"We advocate clean energy, like wind and solar power,"
Bell said. "The Department of Energy has found that we
can produce 20 percent of our energy requirements from
those sources by 2020, which will also lessen demands
on natural gas and reduce the price ... By making our
air conditioners alone 30 percent more efficient, we
could save the need for 204 power plants, saving
61,400 megawatts of power -- about as much power as
went out during the blackout this summer."
The Bush administration has other ideas. Its energy
bill, which currently is stuck in Congress, puts a
priority on nuclear power. It contains a subsidy of
1.8 cents per kilowatt hour for nukes, 20 percent
higher than the 1.5 cents per KWh for alternative
energy. The nuclear subsidy "represents one of the
largest industry giveaways in the entire bill, and
would cost each family in America on the order of
$600," said Daniel Hirsch, president of the Committee
to Bridge the Gap, a nuclear policy group in Los
Angeles.
"Exchanging one set of environmental consequences for
another is not a real solution," said Gunter of the
coal-vs.-nuclear question. "The long-term impacts of
nuclear waste represent a daunting environmental
problem. Long after the last watt of electricity is
produced, succeeding generations will receive all of
the environmental liability." Moreover, he said,
nuclear energy is not really free of carbon dioxide
emissions. Just as solar component manufacturing
causes greenhouse gas emissions, so does processing
uranium fuels.
A study by Dr. Nigel Mortimer for Friends of the Earth
in England, which is widely cited by nuclear
opponents, found that a nuclear plant, through its
fuel cycle, emits as much CO2 as an equivalent coal
plant. The industry contests this conclusion, however,
finding CO2 emissions are somewhere between 0.5
percent to 4 percent of the emissions from equivalent
coal-fired generating capacity.
Len Ackland, who wrote the book, "Making a Real
Killing," about the U.S. nuclear weapons facility at
Rocky Flats, Colo., and a former editor of the
Bulletin of the Atomic Scientists, said there is much
more to nuclear power than CO2 emissions. "Nuclear
power needs to be looked at in totality, and not in
little slivers," Ackland, who also is co-director of
the Center for Environmental Journalism at the
University of Colorado in Boulder, told UPI. Both the
environmental community and the industry "are looking
at a snapshot rather than the whole film," he
continued. In addition to traditional environmental
concerns, such as clean air and CO2 emissions, there
are at least two other, major worries. "One is
operating risk," he said. "Chernobyl is the example of
operating risk. You have to put that in the equation."
The other is the connection between nuclear power and
nuclear weapons. Though this is not necessarily a
safety concern within U.S. borders, it persists as a
threat in other nations. "The case of Iran is right on
point," Ackland said. For years, the United States
has been exporting research reactors all over the
world under the Atoms for Peace program instituted by
President Dwight D. Eisenhower. "Every nuclear plant
creates plutonium," he said. "Is that plutonium
separated from the spent fuel? That's what North Korea
did. That's where the plutonium for their bombs came
from -- by reprocessing the used fuel."
The weapons material argument may be strongest against
nuclear power in the age of terrorism, and the reason
why environmentalists may find support among
non-believers in opposing it. It is much harder to
make a weapon of mass destruction out of coal than out
of spent nuclear fuel. Harder still to make one from
the wind or the sun.

Movies Off The Web Possible by 2005
HOLLYWOOD (UPI) -- Hollywood executive Jack Valenti
has said
technological developments could mean newly released
films being
available online by 2005. The Motion Picture
Association Of America
chief said issues of secure delivery were nearly
resolved, and that
eventually, the BBC reported films could go straight
from big screen
to Internet well before rental release on DVD and
videotape. According
to Valenti, film industry insiders are working with a
number of
companies, including Microsoft and Hewlett-Packard to
develop a secure
system for delivering films to the Internet.
"I really do believe that maybe by this time next year
we'll be able
to have the beginnings of some really sturdy,
protective clothing to
put about these movies," Valenti said. Many of this
year's
blockbusters, including "The Matrix Reloaded" and
"Hulk" were
available before they were released in theaters. One
service,
Movielink, allows users to download films for a fee --
although most
films are not made available until a few months after
they have been
in theaters, and currently the service is only
available in the United
States.
