World's Oldest Nuclear Power Plant Closes
LONDON (June 29) - The world's oldest operational nuclear power
station was closed Tuesday, ceasing electricity generation after
nearly 45 years.
The British Nuclear Group said the Chapelcross station near Annan in
Scotland was officially switched off Tuesday morning.
Chapelcross, which began providing electricity for the south of
Scotland in 1959, was not originally slated for closing until 2008.
But an economic review of Britain's entire Magnox reactor capability
showed Chapelcross and another facility, Calder Hall at Sellafield in
northern England, were making a loss. Calder Hall has also been
earmarked for closure.
"As the world's currently longest-serving nuclear power station,
Chapelcross has earned a rightful place in the record books as a
faithful provider of electricity to southwest Scotland and the north
of England," said Mark Morant, managing director of British Nuclear
Group's Reactor Sites business.
Some 800 people are employed at Chapelcross and Calder Hall; Morant
said many would remain at work for some years while the plant is
decommissioned.
Environmental campaigners welcomed the decision.
"What we hope now is that BNG will apply the same financial criteria
to the rest of its operations and close the reprocessing operations
at Sellafield which are also uneconomic," said Jean McSorley of
Greenpeace.
Opened in the 1950s, the power stations at Chapelcross, Calder Hall,
and Galloway in southwest Scotland were the prototypes for another
nine Magnox power stations that were later built across Britain. They
use a natural uranium fuel which is contained in magnesium alloy
cans.
The reactors are cooled by gas which then passes through heat
exchangers to produce steam for the generating turbines.
When Chaplecross was fully operational its four Magnox reactors
produced 194 megawatts of electricity.

Despite fears, nuclear power industry growing - UN
MOSCOW, June 26 (Reuters) - Fears that nuclear power means
catastrophic accidents and the proliferation of atom bombs have not
stopped the nuclear industry from growing, the U.N. International
Atomic Energy Agency said on Saturday.
It was exactly 50 years ago at 5:30 p.m. Moscow time when the Soviet
Union put the world's first nuclear power plant on line in a town
called Obninsk, not far from Moscow.
This was nearly nine years after the United States dropped two atomic
bombs on Japan in 1945, bringing a quick and violent end to the
Second World War and ushering in the nuclear age with its mushroom
clouds and nightmares of nuclear holocaust.
"The more we look to the future, the more we can expect countries to
be considering the potential benefits ... expanding nuclear power has
to offer for the global environment and for economic growth," IAEA
chief Mohamed ElBaradei said before travelling to Moscow for a
conference on nuclear power.
During his four-day official visit to Russia, ElBaradei will have a
series of meetings with high-level Russian officials, including
President Vladimir Putin, to discuss the future of nuclear energy and
the problem of arms proliferation.
But IAEA officials acknowledge that the 50-year life of nuclear power
has hardly been an easy one.
Accidents at Ukraine's Chernobyl plant and Three Mile Island in the
United States have boosted the world's anti-nuclear "green" lobbies
and left atomic energy with a very bad name.
The image of nuclear power has also not been helped by the fact that
the number of atomic weapons states has nearly doubled since the Non-
Proliferation Treaty entered into force in 1970.
But despite its bad image, the IAEA says countries are still building
power plants and the industry is far from dying.
Alan McDonald, an IAEA nuclear analyst, said the reason some
countries choose nuclear energy over more traditional energy sources
like oil, gas or coal was a lack of resources.
"Nuclear power looks good if you have weak alternatives," he said.
While North America has an abundance of coal and gas, countries like
Japan and South Korea do not, and so choose nuclear energy as the
most economically viable energy source.
There is another aspect of nuclear energy that could help the
industry improve its image -- the fact that generating atomic energy
produces almost no "greenhouse" gases, which many countries want to
limit to help stem global warming.
"New nuclear plants are most attractive where energy demand is
growing and alternative resources are scarce, and where energy
security and reduced air pollution and greenhouse gases are a
priority," ElBaradei said.
The agency said that while Europe and North America have virtually
stopped building nuclear plants, Asian countries continue to
construct them to satisfy their power needs.
Of the last 31 nuclear power plants connected to the world's power
grid, 22 were built in Asia, the IAEA said. The agency noted that
there are 27 plants now under construction around the world and 18 of
them are in Asia.
Mike Townsley, a nuclear analyst for the environmental campaigning
group Greenpeace, said it was irresponsible to build new nuclear
power plants since many "civilian power" schemes have fed into
military atom bomb programmes.
"The problem is nuclear power is still seen as a status symbol," he
said, adding: "You only have to look at countries where nuclear
programmes have been smokescreens for weapons programmes -- Iran,
India, Pakistan, Israel, Iraq" and others.
He also said there were insufficient uranium deposits to fuel nuclear
power plants indefinitely, though the IAEA said there are "sizable
quantities on all continents."
Townsley said it was "a dying industry, but one whose deadly legacy
will be with us for hundreds of thousands of years."

Brazil Denies Blocking U.N. at Nuke Plant
BRASILIA, Brazil (June 29) - Brazil's defense minister denied Tuesday
that his country was blocking U.N. inspections of its nuclear
enrichment facilities.
"Brazil accepts inspections," Jose Viegas told reporters. "What we
have to negotiate are the specific characteristics of the safeguard
agreement."
Viegas made his remarks in response to comments by International
Atomic Energy Agency chief Mohamed El Baradei carried in newspapers
Tuesday. He said that Brazil must allow access to the uranium
enrichment plant or stand in violation of international treaties.
Although Brazil signed the Nuclear Nonproliferation Treaty in 1997
and said its nuclear program has purely peaceful objectives,
questions about its commitment have simmered for more than a year.
The government earlier this month confirmed that IAEA inspectors were
denied access in February and March to centrifuges at the facility in
Resende, some 60 miles southwest of Rio.
It cited the need to protect industrial secrets and said the
centrifuges were, and will remain, off-limits for visual inspection.
The centrifuges are used to enrich uranium so it can be used for fuel
in nuclear reactors and potentially in bombs.

Nuclear industry still haunted by Chernobyl - U.N.
MOSCOW, June 27 (Reuters) - The nuclear industry is still struggling
to overcome the damage done to its reputation by Chernobyl, even
though nuclear power is an "environmentally superior" energy source,
the U.N. atomic agency said on Sunday.
"Despite the array of measures that have been put in place since
Chernobyl to offset the possibility of a severe accident, these risks
can never be brought to zero and they continue to weigh heavily on
public perceptions," International Atomic Energy Agency chief Mohamed
ElBaradei said.
The Chernobyl disaster occurred in April 1986, when an explosion at
the Ukrainian power plant spewed a cloud of radioactivity across
Europe and the Soviet Union.
Around 30 people died from radiation exposure after the accident,
nearly 2,000 children later developed thyroid cancer and thousands of
other fatal illnesses have been blamed on it. More than 100,000
people were resettled, causing physical, economic and psychological
hardship.
In a speech at a conference marking the 50th anniversary of the first
nuclear power plant near Moscow, ElBaradei said that the nuclear
power industry has never fully recovered.
He said that in 1986, the year of the Chernobyl accident, atomic
energy accounted for around 16 percent of the world's energy output --
the same ratio as today.
"The environmental superiority of nuclear power as a source of
electricity -- particularly important in light of recent concerns
about greenhouse gases and climate change -- has frequently received
less attention than the accumulation of spent (reactor) fuel and
radioactive waste."
The IAEA has said that nuclear power emits virtually no greenhouse
gases, which are believed to be the cause of global warming.
ElBaradei added that in the future, nuclear power would probably be
recognised as indispensable in developing countries which lack
natural resources like gas, oil or coal.
Later at a news conference, ElBaradei told reporters that greater
reliance on nuclear energy could avoid the "excessive use of fossil
fuel" and prevent an environmental catastrophe.

Earthquake shakes Illinois nukes, no damage reported
NEW YORK, June 28 (Reuters) - Exelon Corp declared "unusual events"
at three nuclear stations in northern Illinois after a small
earthquake shook the region early Monday morning.
The energy company said in statements to the U.S. Nuclear Regulatory
Commission the earthquake did not cause any equipment damage and all
of the reactors continued to operate.
The quake, which occurred at about 1:30 a.m. CDT (0630 GMT), measured
about 4.5 on the Richter scale and was centered about 10 miles north
of Ottawa, Illinois, according to Exelons reports. Ottawa is located
about 80 miles southwest of Chicago.
The Richter scale is used to express the total amount of energy
released by an earthquake. Although the scale has no upper limit,
values are typically between 1 and 9, and each increase of 1
represents a 32-fold increase in released energy.
An "unusual event" is the lowest of four levels of emergency
classification used by the NRC.
The nuclear stations were the 1,600 megawatt Dresden in Morris, the
2,288 MW LaSalle in Seneca and the 1,752 MW Quad Cities in Cordova.
Together the plants can generate enough electricity for more than 5.5
million homes.
Exelon, of Chicago, owns power plants that produce more than 24,000
MW and distributes electricity to 5.1 million customers in northern
Illinois and southeastern Pennsylvania. One MW can power about 1,000
homes.

IAEA says plenty of uranium for nuclear plants
MOSCOW, June 27 (Reuters) - Known and easily accessible uranium
deposits across the globe can provide enough fuel for the nuclear
power industry for 50 to 65 years, the U.N. International Atomic
Energy Agency (IAEA) said.
In a report released for the 50th anniversary of the world's first
nuclear power plant in Obninsk, Russia, this weekend, the IAEA also
said there was plentiful uranium outside of the easily accessible
deposits to be exploited.
"Uranium resources -- deposits with less geological assurance, beyond
current extraction technology or lacking market attractiveness -- are
at least twice as much."
"Technology advances in exploration and extraction technologies will
make them available, if demand for them develops," the IAEA said.
The agency said there are "substantial unconventional resources" in
phosphate deposits and seawater, which contain vast amounts of very
dilute uranium that could be extracted fuel nuclear energy for
millennia once advanced extraction technologies are developed.
The IAEA also pointed out that spent reactor fuel still contains more
than 98 percent of its original energy and can be recycled to get at
the remaining power potential.
"Taking all factors into account, there are certainly no resource
constraints on nuclear power development in the 21st century and,
most likely, for a long time thereafter," said Yuri Sokolov, IAEA
deputy director General for nuclear energy.
