Government rethinks nuclear plan
(Croydon Guardian) Feb 26 - A campaign led by Greenpeace has forced
the Government into a rethink over its nuclear power plans.
The move came after a legal challenge against the consultation
process was upheld.
A High Court judge ruled that the process undertaken before making
the decision last year was "misleading, seriously flawed and
procedurally unfair".
advertisementGreenpeace said it was pleased the court agreed with
them. It also urged ministers to "go back to the drawing board".
Industry Secretary Alistair Darling said the Government would not
appeal and accepted the decision.

Revealing X-ray scanner makes its debut
PHOENIX (USA TODAY) Feb 26 - The nation's newest airport-security
machine scanned traveler John DeSoto this weekend and found something
that had eluded metal detectors in the past: the thin gold chain and
cross he wears under his shirt.
Backscatter X-ray, which photographs passengers under their clothing,
could close a major security loophole by finding plastic bombs
strapped to a terrorist's chest or other hidden non-metal weapons.
The Transportation Security Administration (TSA) began testing the
advanced technology on Friday at Phoenix Sky Harbor International
Airport and vows to find items elusive to metal detectors and more
consequential than jewelry.
"It's a new day in aviation security," said TSA technology chief
Michael Golden.
Advanced scanners became a higher priority in August after
authorities foiled an alleged plot by terrorists in Britain to bomb
U.S.-bound airplanes with liquid explosives. Similar machines will be
tested this year at Los Angeles International Airport and New York's
Kennedy International Airport and could be installed in airports
across the USA.
The test, slated to last several months, will determine how well the
machine finds weapons, how quickly it scans passengers and how people
feel about a device the American Civil Liberties Union has branded a
"virtual strip search."
The TSA ordered the machines modified to produce cartoon-like
sketches of passengers instead of the graphic photos backscatter
ordinarily generates.
The American Civil Liberties Union remains skeptical. "The problem
with the obscured images is that they obscure weapons," said Barry
Steinhardt, head of the ACLU's technology and liberty program. Even
if passengers can choose between backscatter and a pat-down, "That's
a false choice," Steinhardt said. "Both are intrusive."
Backscatter makers American Science and Engineering and Rapiscan
Systems acknowledge that erasing body-part images also inhibits
weapons detection.
Backscatter X-ray is used only on passengers getting extra screening
- those who trip a checkpoint alarm or those selected by a
computerized profiling system. The passengers can choose a
traditional pat-down or opt to be screened by the backscatter X-ray.
The TSA said about 70% of passengers who required extra screening at
the test checkpoint in Phoenix this weekend chose the backscatter X-
ray method.
DeSoto was impressed with the new technology.
"I was really happy to see they were able to pick up my chain,"
DeSoto, 48, said Friday after he was the third U.S. passenger
screened by backscatter. "It's very thorough."
Other Phoenix passengers liked backscatter for more personal reasons.
"I didn't really want people touching me," said Sarah Atwill, a high-
school junior from Phoenix who was flying to Long Beach.
In Phoenix, the machine operates in Terminal 4 at a checkpoint used
by about 8,000 US Airways or international passengers. Those getting
extra screening are handed a backscatter brochure that emphasizes its
low radiation, equivalent to the exposure from two minutes of flying.
Joe Reiss, vice president of marketing for American Science, which
makes the machine in Phoenix, predicted most passengers will opt for
backscatter because, "People feel that employing this technology can
be helpful for security."
The $100,000 machine, on loan for the test, is as big as an
industrial-size refrigerator. It photographs the front and back of a
passenger as he or she stands inches away with arms raised. A
screener, who is the same gender as the passenger being screened,
studies the photos on a screen in a room 50 feet away. She radios to
a screener stationed at the machine and describes objects on the
passenger that need to be hand-checked.
The process takes about a minute - roughly as long as a pat-down -
but longer if any suspicious item is found. Passenger images are
deleted immediately, the TSA says.
"This is very easy," said Kenneth Johnson, 64, of Mesa, Ariz., after
he became the first passenger screened by backscatter. A dozen TSA
screeners and officials, including a few who had flown from
Washington to launch the machine, stood by and applauded.
Cici Stevens of Prescott, Ariz., opted to be patted down Friday in
Phoenix. Stevens, 42, had recently undergone a slew of medical tests
that left her wary. "I'm just scared of going through anything
electronic," Stevens said. "I don't trust technology."

Israel to hold nationwide nuclear attack drill
JERUSALEM (AFP) - Israel will next month stage its first-ever
nationwide drill simulating a nuclear and chemical missile attack on
its cities, rescue services said Monday.
The exercise was initiated by the army's homefront corps in the wake
of last summer's war in Lebanon and Iran's calls for the destruction
of the Jewish state and its controversial nuclear programme.
Israel suspects is Iran is aiming to develop an atomic bomb, but
Tehran insists its programme is for civilian energy purposes.
The main scenarios which will be simulated are a massive rocket
attack on cities as well as a "conventional and non-conventional
missile attack," Magen David Adom rescue services spokesman Yerucham
Mandola told AFP.
During the drill -- which will include army rescue forces, police,
medical and firefighting services -- air-raid sirens may be sounded
across the entire country.
The Hezbollah militia fired over 4,000 rockets against northern
Israel during the war last summer, killing more than 40 civilians and
paralysing the region's industry and economy.
During the 1991 Gulf War, Israeli citizens were equipped with gas
masks out of fear of a chemical attack. None of the missiles fired
from Iraq against Israel were equipped with chemical warheads.

Iran Earmarks $1.4 Billion Funding For Nuclear Power Plants - TV
TEHRAN (AP)--Iran said Monday it has earmarked $1.4 billion for
construction of nuclear power plants amid international pressure to
abandon its nuclear program, state television reported.
Word of the planned funding came as top members of the U.N. Security
Council were meeting in the U.K. Monday to consider additional
sanctions on Iran for its refusal to suspend uranium enrichment, a
key nuclear process.
An Iranian parliament committee, reviewing next year's budget,
approved the $ 1.4 billion appropriation for building new reactors,
10% of which will go for training staff, the TV report said.
The decision requires approval by the majority of 290-seat parliament
members and a constitutional watchdog to be a law.
Iran has already said it plans to build as many as 20 nuclear
reactors, part of a project to generate 20,000 megawatts of
electricity through nuclear power within the next two decades.
But it could face delays in opening its first nuclear plant, a $1
billion project still under construction with Russian help at
Bushehr. Russia said earlier this month its uranium fuel deliveries
for Bushehr could fall behind schedule because of Iran's delays in
payment.
Iran denied it had failed to make payments and raised concerns Moscow
was buckling under international pressure and delaying the reactor's
launch. Iran expects the Bushehr plant to begin generating
electricity this year.
The TV report didn't say if any of the new appropriation by
parliament would go toward the Bushehr plant.
The U.S. and other Western nations accuse Iran of seeking to develop
nuclear weapons, a claim Iran denies, saying its nuclear program is
intended only to generate electricity.
The U.N. has demanded Iran suspend uranium enrichment, a process that
can either produce fuel for a reactor or the material needed to build
a nuclear warhead.
----------------
The ups and downs of TVA's nuclear program
Twenty-eight percent of the power produced by TVA comes from five
nuclear reactors at three different plants. This falls far short of
the seven plants and 17 reactors that were once on the TVA drawing
boards.
Demand for electricity had mushroomed in the 1960s and 70s. To meet
the demand, work began on nuclear plants at Bellefonte in Alabama,
Yellow Creek in Mississippi, Hartsville in Middle Tennessee, and
Phipps Bend in upper East Tennessee.
But in the early 1980s, demand for electricity leveled off, and two
members of the three-member TVA Board, S. David Freeman and Richard
Freeman (no relation) wanted to stress conservation rather than
continue to pour money into TVA nuclear plants.
After already spending billions on the uncompleted plants, they were
deferred, one after another, and later, canceled altogether. After
Phipps Bend was canceled, the huge reactor was cut up into scrap
metal. The $11 billion spent on canceled nuclear plants is a large
part of TVA's current $25 billion debt.
And in another blow to TVA's once-thriving nuclear program, the
operating plants were in trouble, due to documentation problems,
safety defects and employee complaints. Retired Admiral Steven White,
a veteran of the Navy's nuclear program, was brought in to turn TVA's
troubled nuclear program around.
After years of struggle and criticism, TVA's nuclear program has re-
emerged in the past decade, winning industry awards for safety and
performance. Brown's Ferry will see another reactor come on line in
May 2007, and there's talk of further expansion.
TVA's nuclear program is one of "Our Stories: 51 years of East
Tennessee on TV."

India likely to export nuclear power technology
(IRNA) India may soon become an exporter of nuclear power technology
with at least two south Asian countries having approached the Nuclear
Power Corporation of India Ltd (NPCIL) to develop plants for them.
Two countries have approached them to develop 220 MW plants and to
train the personnel necessary to man the plants, PTI reported here
quoting NPCIL Chairman and Managing Director S K Jain.
Refusing to name the countries, Jain said their delegations had
already met him and were shown existing plants, designs, schedules,
costing and safety parts -- all of which had met with their approval.
"However, since we at present do not have sanction to export nuclear
technology we will have to wait until it is granted by the
international community," Jain said.
He was speaking to reporters after Unit 3 of Kaiga Atomic Power
Station, Karnataka, achieved criticality today after its first self-
sustained thermo-nuclear reaction.
Jain said NPCIL plans to construct eight 700 MW units and ten 1,000
MW units in five years.
"Construction of these projects matches the progress made in mining
of uranium in the country, whose supply is expected to double.
By the time construction of the plants is completed there will be
sufficient fuel for them," Jain said.

Nuclear waste could be routed through Ga.
North Augusta, S.C.(The Atlanta Journal-Constitution) Feb 25 - Two
South Carolina sites are in the running for a federal initiative that
could send thousands of truckloads of nuclear waste through metro
Atlanta.
Proponents of the plan say it's safe and that nuclear materials have
been transported through the state before without incident.
A truck carrying silos of nuclear trash rolls through metro Atlanta
on its way to South Carolina in 2001. Truck transport of nuclear
materials, in Georgia and elsewhere, has a good safety record. But
critics fear the region could become a nuclear dumping ground.
But transport is the least of the concerns of environmentalists and
anti-nuclear activists who oppose President Bush's Global Nuclear
Energy Partnership.
They are more concerned about what will happen if Savannah River
Site, a federal facility near Augusta that made nuclear weapons
materials during the Cold War, or a landfill for low-level
radioactive waste next door in Barnwell, S.C., are chosen for the
nuclear initiative.
If the U.S. Department of Energy selects one or both, opponents fear
they will become the de facto Yucca Mountain. The Nevada depository
is the only long-term solution for the country's nuclear waste, but
it's at least 10 years away from opening and is gaining opposition.
Robert Guild of the South Carolina chapter of the Sierra Club warned
that his state "will become the world's nuclear waste dumping
ground."
But backers of moving the materials to South Carolina say the
concerns are overblown. Many are people who have lived close to SRS
and its nuclear materials for decades, and they say there have been
comparatively few problems.
Local supporters also estimate the initiative could bring 7,000 jobs.
"The nuclear industry is the most highly regulated industry in the
world and is one of the safest," said Carl Gooding, a council member
from nearby Allendale County, S.C.
The Energy Department is considering 13 locations nationwide for one
or more components of the president's global nuclear initiative,
which is still years from reality.
Details of the Global Nuclear Energy Partnership still need to be
worked out - including taxpayers' cost - but the first phase of the
plan calls for collecting used nuclear fuel, or spent nuclear rods,
from commercial reactors and shipping it to a reprocessing facility
where it would be converted into fuel for a commercial reactor.
The spent fuel, which would be shipped in stainless steel and lead
casks, could come from any of the 65 nuclear reactor sites in the
United States. most of them east of the Mississippi River.
Eventually the program would help U.S. companies sell the reprocessed
nuclear fuel abroad for electricity.
The Department of Energy is scheduled to narrow its choices of sites
for the program, and which companies could run it, by the summer of
2008.
Radioactive tanks leak
Savannah River Site already has about 37 million gallons of
radioactive liquid waste in large tanks, some of which are more than
50 years old and leaking. Every year, the federal government spends
more than $1 billion a year on cleanup at SRS.
But at a Department of Energy public hearing this month, federal
officials heard many positive comments about the proposal for the
Global Nuclear Energy Partnership from elected representatives and
business leaders eager for the economic boost. Jobs and the tax base
in the region have eroded since SRS started ramping down in the
1980s.
Scott MacGregor, vice president of the Augusta Metro Chamber of
Commerce, said the partnership is "the type of forward-thinking
Augusta is proud of ... together we can meet the needs of the
future."
Residents of Augusta and, just over the state line, the South
Carolina communities of Aiken, North Augusta and Jackson, are
accustomed to the 198,000-acre nuclear facility, which has operated
in their backyard for more than 50 years.
Several generations of families have gotten their paychecks from SRS
and no major accident has occurred. A report by the Atlanta-based
Centers for Disease Control and Prevention recently predicted a
minimal risk of cancer for people living nearby.
Proponents and opponents of Bush's plan agree the adjacent South
Carolina sites both have a good chance for two reasons. The location
is close to many of the nation's nuclear reactors that will provide
the waste for reprocessing, and to major ports. Second, a
reprocessing facility was built in Barnwell, near SRS, in the 1970s,
but never opened.
Much will depend on congressional support. Congress sliced this
year's proposed funding from $380 million to $120 million.
Jim Hardeman, manager of the Georgia Environmental Protection
Division's Environmental Radiation Program, said if a South Carolina
site is chosen, there's a good possibility most of the shipments of
spent nuclear rods would either be trucked around I-285 or railed
through downtown Atlanta, winding past Philips Arena and the state
Capitol.
"Some of the maps they've put together to show nuclear waste
transportation to Yucca, flip around and show them going to Savannah
River Site," Hardeman said. "That's kind of what it would look like."
Government officials say the transportation of spent nuclear rods
poses minimal risks to the public. According to the Department of
Energy, a person standing 6 feet from a truck carrying casks full of
spent nuclear fuel for one hour would receive a radiation dose
equivalent to a chest x-ray.
They also say terrorism risks are minimized by keeping shipment
routes and schedules secret. Only a designee in the governor's office
of each state on the route is notified, officials said. Some
shipments get law enforcement escorts.
Train and traffic accidents are always possible, but in 50 years of
shipping radioactive material in the United States, there have been
fewer than a dozen traffic accidents and no release of radioactive
material, said James Giusti, spokesman for the Department of Energy.
When the Department of Energy studied transportation routes for Yucca
Mountain, it concluded a release of radioactive material is likely to
occur twice in 10 million years. Such an event would not cause even
one cancer death, the government said.
Hardeman, with Georgia's EPD, said his office is monitoring the
latest proposal for the Savannah River Site.
The plutonium route
If the South Carolina sites are chosen, it won't be the first time
radioactive material has traveled over Georgia roads and rails.
Starting in 2002, about six tons of bomb-grade plutonium was trucked
through Georgia from a Colorado nuclear weapons plant to Savannah
River Site. South Carolina's governor at the time, Jim Hodges,
protested the shipments. He unsuccessfully sued the federal
government over concerns that it did not have a plan for permanently
storing the material.
In a separate plan already approved and in the works at Savannah
River Site, many more plutonium shipments are slated to begin once
the government completes construction of a new plant there: the fuel
facility.
The plant will convert weapons-grade plutonium into commercial
reactor fuel to produce electricity. The $1 billion facility will
bring thousands of radioactive truck shipments to and from SRS and
over Georgia roads.
Among the proponents of South Carolina's sites are Sens. Saxby
Chambliss (R-Ga.) and Johnny Isakson (R-Ga.). In a joint letter read
at a February hearing before the DOE, they said nuclear energy is
"safe, affordable and environmentally friendly."
"Be careful what you ask for," says Glenn Carroll, coordinator for
Nuclear Watch South in Atlanta, formerly Georgians Against Nuclear
Energy. "We already have 35 million gallons of high-level waste [at
Savannah River Site], and we don't know what to do with it."

Solar System Offers No Safe Place from Radiation
(Red Orbit) Feb 26 - Imagine hiking across Antarctica, through ice,
cold and bitter wind, enduring months of hardship, and finally
arriving at the doorstep of the South Pole itself.
At that moment you get hit by a Sahara sandstorm.
That's the analogy scientists are using to describe what happened to
the ESA-NASA Ulysses spacecraft last December. "Ulysses was
approaching the South Pole of the sun when it was 'sandblasted' by a
cloud of high-energy particles-protons, electrons and heavy ions,"
says Arik Posner, Ulysses Program Scientist at NASA headquarters. The
cloud was as foreign to the sun's South Pole as a Sahara sandstorm
would be to Antarctica.
The strange tale begins on Dec. 5, 2006.
Astronomers were in a state of excitement due to the sudden
appearance of a giant and angry-looking sunspot on the sun's eastern
limb-"sunspot 930," says Posner. On Dec. 5th it exploded, producing
one of the strongest solar flares of the past 25 years. On the
"Richter scale" of solar flares, X1 is considered intense; the Dec.
5th flare was an X9. A flash of X-rays announced the blast to sensors
in Earth orbit, and moments later a cloud of protons, electrons and
heavy ions came rushing out of the blast site. This is the cloud that
pelted Ulysses.
The process repeated on Dec. 6th (X6) and Dec. 13th (X3). Each
explosion created its own cloud of high-energy particles. "We call
these clouds 'radiation storms,'" says Posner. "They are common after
big flares."
What's strange about these storms is where they went-to the South
Pole. "All three storms were detected by the Ulysses spacecraft,"
says University of New Hampshire physicist Bruce McKibben. He is
principal investigator for COSPIN (Cosmic and Solar Particle
INvestigation), an array of sensors onboard Ulysses that counts high
energy particles. "The Dec. 6th event was particularly strong and
rich in heavy ions."
The Dec. 6th storm was so strong, in fact, "that if Earth had been
where Ulysses was, we would have experienced a full-fledged Ground-
Level Event," says Prof. Bernd Heber of the Institute for
Experimental and Applied Physics in Keil, Germany. In other words,
the particles were capable of tunneling all the way through Earth´s
atmosphere to reach the ground. Heber is principle investigator for
the Kiel Electron Telescope (KET), a sensor onboard Ulysses able to
detect such super-energetic electrons, protons and ions.
These observations add up to "a big puzzle," says McKibben. Sunspot
930 was near the sun's equator, while Ulysses was over the sun's
South Pole. The sun's magnetic field should have kept the storms
bottled up at low latitudes. How did they reach Ulysses?
It's a puzzle NASA is keen to solve. Solar radiation storms can cause
communication blackouts on Earth; they can disable satellites in
Earth-orbit; and in extreme cases they could be deadly to astronauts.
"We need to be able to predict the trajectory of these storms," says
Posner.
Heavy ions (Z>2) counted by Ulysses over the sun's south pole vs. ACE
over the sun's equator in Dec. 2006.
The Parker Spiral. Image credit: Steve Suess, NASA/MSFC. The key is
the sun's magnetic field. Just as Earth's magnetic field guides
compass needles, the sun´s magnetic field guides radiation storms.
"Radiation storms consist of charged particles which naturally follow
lines of magnetic force."
To forecast the path of a radiation storm, researchers have in the
past relied on the "Parker spiral," a pioneering magnetic model
developed by University of Chicago physicist Eugene Parker. According
to his work, the sun's magnetic field emerges radially from the sun's
surface and spirals outward into the solar system. "The spiral shape
is caused by the spinning motion of the sun," explains Posner. "It's
like a spiral stream of water from a spinning lawn sprinkler."
The Parker spiral makes a straightforward prediction: Radiation
storms that begin near the equator should remain near the equator. A
storm might expand into the solar system and hit Earth, which is not
far off the sun´s equatorial plane, but it should not hit Ulysses
over the sun's South Pole.
Clearly, there's more to the story than a graceful spiral. The real
solar magnetic field may contain kinks and twists that provide a
polar passage, a route storms can travel from equator to poles. There
is evidence for the idea: In 2000 and 2001, the last Solar Max, the
sun's magnetic field was full of convoluted, non-Parkerian
structures. "During that time, Ulysses experienced six high-latitude
radiation storms," notes McKibben: data.
Mapping and understanding these passages, if they exist, is work for
the future. Meanwhile, one thing is clear: "There is no place in the
inner solar system completely safe from radiation storms," says
Posner
