Westinghouse Electric Co. agreed Tuesday to build four nuclear power
plants in eastern China.
Monroeville, Pa.-based Westinghouse and partner Shaw Group of
Louisiana, agreed to the deal involving the State Nuclear Power
Technology Co. of China (SNPTC), Sanmen Nuclear Power Co., Shandong
Nuclear Power Co. Ltd., and China National Technical Import & Export
Corp.
Construction will begin in 2009, with the first plant slated for
operation in 2013 and the remaining three coming on line in the next
two years, Westinghouse said in a statement. It did not give specific
financial terms but said the deal would create some 5,000 jobs in at
least 20 states in the United States.
Westinghouse will build four 1.1-gigawatt reactors using its advanced
AP1000 design, a technology the company said is the basis for nearly
half of the world's operating nuclear plants.

American acceptance of nuclear power grows
BOSTON (Reuters) JUL 24 - As the price of oil rises, so has the
number of Americans who believe nuclear energy is an acceptable
source of power, although the pro-nuclear camp is still a minority, a
study showed on Monday.
The survey by the Massachusetts Institute of Technology found 35
percent of people in the United States favored increasing the
nation's reliance on nuclear energy, up from the 28 percent who held
that view five years ago.
The 35 percent who wanted to increase nuclear power usage exceeded
the 28 percent who wanted to reduce its use, it said.
Concerns about how to safely store nuclear waste were one of the main
factors influencing those who remain reluctant to expand nuclear
operations, said Stephen Ansolabehere, the MIT political scientist
who conducted the March survey of 1,200 people across the country.
"That uptick is favorable, but it's not a huge transformation. It's
not like we've gone from a solid majority against to a solid majority
in favor," Ansolabehere said.
"The level of discomfort with the technology has a lot to do with
what is the big unsolved problem both at the elite level and at the
public level -- which is how do you handle the waste?"
The survey found only 28 percent of U.S. residents believed nuclear
waste could be stored safely.
The finding comes at a time when officials in Washington and the
power industry are calling for a "nuclear renaissance." The 100 U.S.
nuclear reactors are approaching the end of their lifespans, and
power industry officials have said a wave of construction will be
needed to keep nuclear's current share of 20 percent of the nation's
electricity supply.
Merchant power company NRG Energy Inc. is planning to build a plant
in Texas that would be the nation's first new nuclear power facility
in about three decades.
Industrial conglomerates including General Electric Co., Hitachi
Ltd., which have joined forces in the nuclear business, and Toshiba
Corp. are stepping up their efforts to capitalize on the potential
building boom.

Energy industry gears up for 'nuclear renaissance' by Jacques Lemieux
MCCLEAN LAKE, Canada (AFP) Jul 24 - Twenty years after the Chernobyl
disaster poisoned the world's taste for reactors, a French firm is
sniffing out fresh uranium supplies in Canada. And the race for
nuclear power is back on.
After the deadly Chernobyl reactor explosion in Ukraine in 1986 and a
lesser scare at the Three Mile Island in Pennsylvania that rattled
the United States in 1979, "people were wondering whether nuclear
power even had a future," said Yves Dufour, one of the directors of
Areva, the world's leading civilian nuclear power provider.
"For 20 years, we've been crossing a desert," the industry's very own
"nuclear winter," said Dufour.
The Three Mile Island meltdown apparently harmed no one but shook
public confidence in nuclear plants. The fallout from Chernobyl,
however, spread widely and affected an estimated five million people.
But now a breath of optimism is warming the sector up, just as it did
during the petrol crisis of 1973.
Areva, based in France -- which alone among western countries
continued to build nuclear power plants after these scares -- is
angling for new uranium supplies for its reactors. Such prospecting
declined sharply in the dark days after Chernobyl.
"The nuclear renaissance has become a fact -- it's a certainty,"
Areva's spokesman Charles Hufnagel told AFP during a tour of this
uranium mine that the company is exploiting in the western Canadian
province of Saskatchewan.
There are 438 nuclear reactors in 30 countries which provide 16
percent of the world's electricity, according to the latest industry
figures.
Most of them were built from the 1960s to early 1980s, and are
getting old. Replacing them could answer concerns about the harmful
global warming caused by the carbon dioxide (CO2) released by burning
fossil fuels.
"Global warming fears, rising fossil fuel prices and surging power
demand in the Far East are fueling a new wave of nuclear plant
construction," according to a report by the Canadian bank CIBC World
Markets.
Hufnagel meanwhile insists economic factors are behind the decisions
of countries such as Finland, Britain, Canada and the United States
to re-launch nuclear power projects.
The aim is "not only to produce electricity that is cheap but above
all at a stable price in the long term," he said. "No country has yet
decided to re-launch a nuclear program just to fight against CO2."
"The nuclear renaissance is also a thing of the south, with big
countries that also wish to be the leaders of their region," he
added, citing the notable examples of China, Brazil and South Africa.
Some 150 new reactors are expected to be built in the next two or
three decades, many of them in China, with the number of active
plants set to double by 2070.
A scramble has begun to start bagging uranium to feed them. Current
uranium production -- after the post-Chernobyl decline in investment
in the sector -- can only feed 60 of the existing reactors' capacity.
Much of the rest comes from stockpiles dating back to the petrol
crisis and recycled nuclear material from ex-Soviet warheads, Dufour
said.
These uranium sources however will soon be exhausted. Mining analyst
John Redstone of Montreal-based investment broker Desjardins
Securities, says uranium supply falls some 1,000 tonnes short of the
current world demand of 66,800.
This is pushing up the price of uranium to new highs, topping 130
dollars per pound compared to less than seven dollars in 2001, he
said.
Producers are responding by stepping up their capacity, said Dufour,
as well as scouring the planet for new sources of the crucial
mineral. "The difficulty for production will be the next three
years."
The opening of new mines in Canada starting in 2009 would boost
supplies and lessen the strain.
But at today's consumption rate, the proven and probable global
reserves of 4.74 million tonnes could feed existing reactors for only
65 years, according to the International Atomic Energy Agency (IAEA).
Those reserves are found mostly in Australia, Kazakhstan, Canada, the
United States and South Africa.
Another 10 million tonnes of uranium that are believed to exist would
push the deadline into the next century. "But we have to go find
these 10 million tonnes," said Dufour.

FDA ruling gives market boost to anti-radiation pill
Minneapolis / St. Paul Business Journal - July 20, Federal regulators
have granted "orphan drug" status to Humanetics Corp.'s product for
combating acute radiation sickness, a decision that will give the
biotech firm tax benefits and rights to market its drug exclusively
for seven years.
The drug, dubbed BIO 300, is still undergoing clinical trials and
hasn't received final approval from the U.S. Food and Drug
Administration (FDA). However, the designation will provide the firm
with additional patent protection and other perks.

IAEA to send team to quake-hit nuclear plant
VIENNA (Reuters) - The U.N. nuclear watchdog will send a team of
experts to Japan in the coming weeks to check the world's biggest
nuclear power plant after a powerful earthquake last week caused
radiation leaks, the agency said on Tuesday.
Tokyo Electric Power Co.'s Kashiwazaki-Kariwa nuclear power plant
leaked water containing radioactive materials from a reactor after a
6.8 magnitude quake struck northwest Japan on Monday last week. The
leaks rekindled fears about the safety of Japan's nuclear industry.
"This invitation is important for identifying lessons learned that
might have implications for the international nuclear safety regime,"
the International Atomic Energy Agency (IAEA) said in a statement.
Initially, Japan had told the IAEA it did not need help, but on
Monday it said it would allow inspectors into the quake-hit plant
after coming under pressure from local authorities.
The plant was shut down automatically in the quake and will remain
closed indefinitely for safety checks. Japan has ordered other
nuclear plant operators to make strict safety checks.
The exact timing of the joint Japanese-IAEA examination will be
decided in consultation with the Japanese authorities, the IAEA said,
stopping short of giving any dates. The Nikkei business daily
reported that four IAEA inspectors would visit the site as soon as
early August.
Nuclear energy supplies around one-third of the country's electricity
needs in Japan, which now has 55 nuclear reactors.

Small fire breaks out at Japanese nuclear plant
TOKYO (AP) Jul 24 - A small fire has broken out at a nuclear power
reactor under construction in northern Japan, the third blaze there
this month.
The plant's operator, Hokkaido Electric Power Co., said in a
statement today that workers immediately doused the flames and there
were no injuries and no danger of a radiation leak.
Authorities were investigating the fire, the third this month at the
Tomari nuclear plant on Hokkaido island, where two other reactors
were operating normally.
Kyodo News agency said investigators found damage to electric wiring,
and suspected foul play.
The fires come amid heightened concerns over nuclear safety in Japan
after an earthquake ravaged a nuclear power station on the country's
main island of Honshu, causing radiation leaks, burst pipes and
flooding.

Earthquake stokes fears over nuclear safety in Japan
TOKYO: Japanese concerned over nuclear safety
After a deadly earthquake struck northwestern Japan last week, the
nation was stunned when a nuclear power plant near the earthquake's
center suffered widespread damage, including minor radiation leaks,
ruptured pipes, flooding and a fire that belched black smoke for more
than an hour on live television.
But perhaps the most startling discovery came in the days that
followed, when scientists used data from the magnitude 6.8 earthquake
to conclude that the builders of the Kashiwazaki-Kariwa plant, the
world's largest by electrical output, may have unknowingly
constructed it directly on top of an active seismic fault.
"Not finding the fault was a miss on our part," said Toshiaki Sakai,
who heads the engineering group in charge of Tokyo Electric's nuclear
plants. "But it was not a fatal miss by any means."
The earthquake, which killed 11 people and destroyed hundreds of
homes in the nearby city of Kashiwazaki, has raised questions about
the safety of Japan's nuclear plants.

The plants in this earthquake-prone nation are supposed to be nearly
quake-proof, built to withstand the most powerful punch. Tokyo
Electric Power, the plant's operator, said the tremors last week were
more than twice as strong as the plant's design limits. So the
plant's vulnerability to damage has distressed many Japanese.
The damage at the Kashiwazaki facility also offered a vivid reminder
of the risks of nuclear power at a time when the United States,
Europe and countries elsewhere are giving atomic energy a second look
as a clean, plentiful alternative to oil and other fossil fuels.
Resource-poor Japan kept building new nuclear plants even after
accidents like Three Mile Island in 1979 in the United States and
Chernobyl in 1986 in Ukraine froze construction in the United States
and parts of Europe for decades.
Nuclear experts applaud the fact that all four of the Kashiwazaki
plant's seven reactors that were operating when the earthquake struck
were safely shut down, despite the unexpected strength of the
tremors. But Tokyo Electric's failure to predict the possible size of
the tremors that could strike the area and to detect the fault line
have left many here wondering whether regulators and plant operators
could also have underestimated the potential for devastating
earthquakes at Japan's 48 other nuclear reactors.
"The plant did an excellent job of ensuring the safety of the
reactors themselves," said Michio Ishikawa, president of the Japan
Nuclear Technology Institute, an industry-sponsored research group.
"But how could they have not known about the active fault line?"
On Tuesday, the Ministry of Economy, Trade and Industry, which
oversees energy-related policy, said it would create an independent
panel to investigate the damage at the Kashiwazaki plant, in Niigata
Prefecture. The panel's findings will be presented to the United
Nations' International Atomic Energy Agency, which also will send
inspectors to the plant.
The discovery of the fault line below the Kashiwazaki plant has
attracted intense media attention in Japan, partly because it echoes
problems that have already plagued nuclear plants elsewhere in the
country. There have been lawsuits seeking the closure of at least
four other plants because of nearby fault lines, including a plant in
the western town of Shika, where a large fault was discovered in
2005, just before the plant's completion.
The earthquake also defied expectations by moving in a different way
from previous earthquakes in the region, Tokyo Electric said. The
plant was designed to withstand shorter, more intense tremors. But
the quake last week struck with a broad, wrenching, horizontal
swaying that caused water to slosh out of storage pools.
About 1,200 liters, or more than 300 gallons, of that spilled water,
contaminated by tiny amounts of radioactive material, made its way
into the nearby Sea of Japan. Tokyo Electric said the levels of
radioactivity in the spill and a separate leak of contaminated
exhaust were far too low to harm the environment. It also said damage
at the plant occurred only in less critical parts of the plant, which
are built to less stringent standards than the reactors, which are
housed in bunker-like concrete buildings.
Tokyo Electric admitted that it had failed to find the fault that
caused the earthquake. The company said the fault line did not show
up in surveys of the area made in the late 1970s, when it started
constructing the plant. But the company said the plant was still safe
because the fault line appeared to lie more than 20 kilometers, or 12
miles, beneath it, too deep to cause the sorts of big cracks and
other surface movement that could damage the reactors' thick concrete
buildings.
Still, critics said the fact that the fault could go unseen pointed
to a bigger problem: the broad discretion that the government gives
power companies in deciding whether a site is safe.
Katsuhiko Ishibashi, a professor at Kobe University who studies
earthquakes and urban safety, was a member of a committee last year
that set new earthquake-safety guidelines for nuclear reactors in
Japan. He said some of the committee's 20 members were academics and
engineers with close ties to power companies, including one who
served as an adviser to those companies.
Ishibashi said the new guidelines, approved in September, were too
vague and left too much discretion to power companies in deciding
whether a plant site was seismically safe. He said he got so angry at
the lack of discussion within the committee about the new guidelines
that he resigned during the final meeting.
The strength of the earthquake in Kashiwazaki "could have been
predicted, and should have been predicted," Ishibashi said. "The new
guidelines are very insufficient and have loopholes."
Plant operators and government regulators called such criticism
unfair. They said the companies' plans face intense scrutiny from
committees of independent academics. They also said the Kashiwazaki
plant was just unlucky: The quake struck a year before Tokyo Electric
was to finish a new survey of the site to ensure that the plant met
the new seismic safety guidelines.
"The company did the best it could with the technology that it had
available when the plant was constructed," said Hitoshi Sato, deputy
director general for nuclear safety at the Ministry of Economy, Trade
and Industry. "If you insisted on being 100 percent sure about
finding all active fault lines, you'd never get anything built."
------------------
Japan underestimated fault line at nuclear plant
Australian Broadcasting Company JUL 24 - Japan's industry minister
has admitted the government had underestimated the possible risks of
building the nation's biggest nuclear power plant near a seismic
fault line.
A deadly earthquake measuring 6.8 on the Richter scale on July 16
caused a small amount of radiation to leak from the Kashiwazaki-
Kariwa plant north-west of Tokyo, fuelling public concerns.
The earthquake struck off the coast just nine kilometres from the
power plant.
"In the way we dealt with it (the fault line) in the ocean area, we
have to agree that the government's action was inadequate," Minister
of Economy, Trade and Industry Akira Amari said.
Before building the plant in the 1970s, operator Tokyo Electric Power
Co submitted a pre-construction report, in which the firm allegedly
underestimated the earthquake risks linked with the fault line in the
area.
The government approved the company's assessment.
Mr Amari said his ministry would toughen its earthquake preparedness
standards when reviewing construction plans for future nuclear
plants.
