Nuclear waste plan not a security hazard - Ridge
WASHINGTON (Reuters) - Transportation of nuclear waste to a proposed
permanent dump site in Nevada could be done safely without undue
danger of disruption by terrorist attack, U.S. Homeland Security
Director Tom Ridge said Thursday.
Ridge said a review of the proposal by his office had concluded that
adequate safeguards for transporting nuclear waste had already been
developed by the Department of Energy and the U.S. military.
The proposed Yucca Mountain storage site would be the nation's first
permanent repository for radioactive waste and has sparked a battle
in Congress.
"We feel very confident that this can be done safely," Ridge told the
American Society of Newspaper Editors. "We don't believe ultimately
that (transportation) should be an impediment."
Nevada Gov. Kenny Guinn vetoed the proposal Tuesday and the site's
fate now rests with Congress, which has 90 working days to sustain or
override the veto. Guinn has predicted an uphill battle to uphold the
veto.

Czech N-plant seen ready for re-start next week
TEMELIN, Czech Republic, April 12 (Reuters) - The Czech Temelin
nuclear power station will be ready to hold controlled fission
reactions at both of its two reactors by the end of next week, a
plant spokesman said on Friday.
The controversial Soviet-designed power station is 60 km (38 miles)
from the border of fiercely anti-nuclear Austria, which has strongly
opposed its operation.
Temelin spokesman Milan Nebesar told Reuters the plant's first
reactor, shut for an inspection seven weeks ago, should be ready for
a re-start from the middle of next week, pending permission from
Czech nuclear safety regulators.
He said the second 981 megawatt (MW) VVER reactor, loaded with fuel
in mid-March and preparing for the activation of its inaugural
nuclear fission reaction, should be ready by the end of next week.
Temelin's owner, state-owned power utility CEZ (CEZPsp.PR), has been
testing the first reactor since late 2000, but the full commercial
launch has been delayed due to a series of glitches in the plant's
secondary, non-nuclear circuit.
The power station, which has been upgraded with western control
systems, has become a source of unrelenting friction between the two
central European neighbours. Germany has also opposed Temelin.
The EU, however, has said the plant is not an issue in the Czechs'
drive to join the 15-nation bloc, expected in 2004.
The International Atomic Energy Agency, the world's nuclear watchdog,
told a news conference at the plant on Friday its team of experts
inspecting Temelin had found the plant sufficiently protected against
a security breach.
David Rex Ek, head of the agency's team, told journalists the
station's physical protection by electronic systems, security guards
and other means was comparable with Western European nucler power
plants.
The watchdog's week-long mission, which ended on Friday, did not look
at other safety issues.

Japan processes dismantled Russian nuke into MOX fuel
MITO, Japan, April 12 (Kyodo) - The Japan Nuclear Cycle Development
Institute announced Friday it has successfully refined plutonium
removed from dismantled Russian nuclear weapons into plutonium-
uranium mixed oxide (MOX) fuel, which was then burned in a Russian
nuclear reactor.
Officials of the institute said it is the first international
cooperation effort under which a Japanese institute dismantled
Russian nuclear weapons
The institute has processed about 20 kilograms of plutonium, taken
from Russian nuclear weapons in cooperation with Russia's Research
Institute for Atomic Reactors (RIAR), into MOX fuel since 1999.
The institute then burned the fuel in the Russian BN600 fast reactor,
and confirmed there were no abnormalities in the fuel, the officials
said.
The institute is expected to dispose of 20 tons of plutonium to be
extracted from dismantled Russian nuclear weapons by 2020, the
officials said.
MOX fuel is designed to be used in light-water reactors in the so-
called ''pluthermal process,'' which the Japanese government has
deemed necessary for its nuclear fuel cycle policy.

Standoff Over Plutonium Shipments
COLUMBIA, S.C. (AP) - South Carolina's governor and the federal
Energy Department are locking horns over planned plutonium shipments
to the state - a dispute federal officials say is delaying nuclear
cleanup nationwide.
The Energy Department wants to ship plutonium from a former nuclear
weapons site in Rocky Flats, Colo., to a plant near Aiken, S.C.,
where it would be converted into fuel for nuclear reactors.
Gov. Jim Hodges says he supports the idea, but he won't allow the
weapons-grade material into the state until the government agrees to
make the shipping agreement legally binding.
It appeared the standoff had ended Thursday after the governor agreed
to a written proposal from Energy Secretary Spencer Abraham that said
he would send a 30-day notice of when the shipments would begin. But
Hodges also wanted a consent order filed in federal court that would
have let a judge order the Energy Department to remove the plutonium
if it did not meet the terms of the agreement.
The department rejected that request, and Hodges said the situation
is back to square one.
Hodges wants the Energy Department to provide a document outlining
schedules to fund the construction of Mixed Oxide, or MOX, fuel
treatment facilities, when to expect the shipments and when they
would leave South Carolina.
``All I want to know is whether I've got something I can run down to
the federal courthouse if they don't honor the terms and get a judge
to stop shipments,'' he said Thursday.
Abraham said the agency addressed Hodges' concerns in the proposed
agreement by establishing annual funding targets, committing to
notify the state of all plutonium shipments and including firm dates
that the material would be removed from the state if the Energy
Department was unable to come up with the funds to build the MOX
facility.
President Bush included $384 million to fund the plutonium
disposition program in the next fiscal year, beginning July 1. The
budget also noted that the project would require funding of $3.8
billion over the next 20 years, Abraham wrote.
The standoff springs from the federal government's plan to clean up
Rocky Flats, northwest of Denver, and turn it into a wildlife refuge.
Rocky Flats made plutonium triggers for nuclear weapons for 40 years,
but it closed in 1989. To meet the 2006 conversion deadline, the
Energy Department needs to begin shipping plutonium soon, although
department officials won't give an exact date.
The state and federal governments' inability to reach an agreement
has held up cleanup activities at former nuclear plants across the
nation, Abraham said. It also jeopardizes the 2000 U.S.-Russian
plutonium disposition agreement, he said.
``We need to move forward with the MOX plant that will be used to
dispose of the plutonium at issue in order to honor our commitments
to the Russian Federation,'' Abraham wrote.

Russia aims to build Vietnam nuclear power plant
HANOI, April 11 (Reuters) - Russia has offered to build Vietnam's
first atomic power plant, a senior Russian executive said on
Thursday, in a long-term project which could take about a decade to
materialise.
The executive from Atomstroyexport, an affiliate of Russia's Ministry
of Atomic Energy, told Reuters Russian nuclear experts gave
presentations to Vietnamese officials, including some from state
utility Electricity of Vietnam (EVN), on Thursday.
The executive, who did not want to be identified, said the Vietnamese
audience included officials from the Planning and Investment Ministry
and EVN's Energy Institute, which is in charge of planning Vietnam's
first nuclear plant.
"We are interested in building such a plant in Vietnam and Russia is
ready to do it," the executive said at a business meeting on the
sidelines of an international trade fair in Hanoi.
Earlier this month, Vietnam's official media said energy authorities
planned to complete a pre-feasibility study for a 2,000-megawatt
atomic power plant, that would cost about $4 billion, by late next
year. Local media did not say how Hanoi would fund the project.
Vietnam and Russia signed an agreement on cooperation in nuclear
power last month during a visit by Russian Prime Minister Mikhail
Kasyanov, but industry sources have said Japan and South Korea are
also interested in building the plant.
The Russian executive said Russia was not concerned about competition
given its experience in the field. He said it was currently building
plants in Iran, China and India.
Last month official media said Vietnam aimed to start operating its
first atomic power plant in 2017 or 2019 to meet rising energy
demand, even though the country has plenty of natural gas and coal,
and suitable conditions for hydropower.
Four possible locations, all in southern Vietnam, have been selected.
Two are in Ninh Thuan province, one in Binh Thuan and another in Phu
Yen.
Vietnam's official media last week quoted Nguyen Manh Hien, head of
EVN's energy institute, as saying it would take at least eight years
to build an atomic plant and around 15 years to train personnel to
run it.

Ohio Utility Offers Repair Plan
WASHINGTON (AP) - An Ohio utility proposed Wednesday the most
extensive repair job ever done to an operating nuclear power plant to
repair two spots of acid corrosion on a reactor head.
The plan, which must be approved by the Nuclear Regulatory
Commission, would use a 300-pound, 5-inch-thick stainless steel
plate, welded into a 13-inch-wide circle around the largest corroded
area of FirstEnergy Corp.'s Davis-Besse plant on the shores of Lake
Erie.
Two steel plugs would be welded into nozzles to blend over the second
corroded area, said Jim Powers, a nuclear engineer for the company.
The nozzles are steel pipes that protect control rods, which are used
to control the amount of power produced or, in an emergency, shut
down the reactor.
The company stressed that although the rods from the damaged nozzles
will be moved, the plant will still be able to operate safely. Davis-
Besse is on the lake about 25 miles east of Toledo, Ohio,
Last month, inspectors found that longtime water leaks had allowed
boric acid to eat a 7-inch-wide hole almost through the 6-inch-thick
steel cap that covers the plant's reactor vessel. The hole was
stopped by an inner lining made of noncorrosive stainless steel.
Critics of the Nuclear Regulatory Commission questioned whether the
agency would be able to monitor the plant enough to keep the
corrosion from recurring.
``This utility has demonstrated a lack of responsibility, and the
regulators have demonstrated a lack of oversight. Those are broader
issues that this repair plan doesn't address,'' said Paul Gunter of
the Washington-based Nuclear Information & Resource Service.
Davis-Besse has been shut down since discovery of the corrosion.
Since then, federal inspectors have begun a review of the 68 other
similarly designed pressurized reactors across the country.
Preliminary findings of the industrywide review have turned up
nothing similar to the Davis-Besse damage, the NRC said this week.
The repairs, expected to cost between $15 million and $20 million,
should keep the plant operating until a refueling shutdown in 2004,
during which FirstEnergy plans to install a new reactor head, said
company spokesman Todd Schneider.
The 24-year-old Davis-Besse plant generates enough power for 450,000
homes, 24 percent of FirstEnergy's nuclear power capacity.

US finds no widespread corrosion at nuclear plants
WASHINGTON, April 10 (Reuters) - A U.S. government-ordered review of
more than five dozen nuclear power plants has not found any corrosion
in reactor caps similar to that at the Davis-Besse facility in Ohio,
a top U.S. energy official said on Wednesday.
The Nuclear Regulatory Commission launched an investigation last
month after a corroded cavity was found in the reactor vessel head of
the 25-year-old plant owned by FirstEnergy Corp <FE.N>. The agency
ordered 68 other similar reactors -- more than half of the nation's
103 nuclear plants -- to look for similar problems.
"I am not aware of any other problems they found," U.S. Energy
Undersecretary Robert Card told Reuters, adding that he had been
briefed by NRC officials on the matter.
"Thus far, there haven't been any surprises or safety issues in the
nuclear plant review," said an NRC spokeswoman.
Card, who was attending a meeting of the National Petroleum Council,
said the Energy Department was worried that if serious corrosion had
been detected, some of these reactors could have been shut down for
up to a year.
That was because the companies that make the huge metal reactor caps
were already behind in filling other orders.
He also said the department was worried that shutting down nuclear
plants would have caused a spike in natural gas prices, as utilities
would be forced to ramp up generation at plants that run on natural
gas.
"If half the nuclear fleet went down for six months, you'd nearly
double the natural gas need. It can't be done," he said.
Natural gas provides 15 percent of electricity generation, nuclear
power accounts for 20 percent and coal about 50 percent.
During a scheduled refueling outage at the Davis-Besse plant that
began Feb. 16, FirstEnergy engineers found boric acid had leaked at
the base of several of the control rod nozzles that penetrate the
reactor.
Boric acid is used in the primary coolant bath surrounding uranium
rods in the reactor core.
At one of the nozzles, the acid had eaten all the way through the
vessel head, which was 6 inches (15-cm) thick. The vessel head is a
massive piece of carbon steel 17 feet (5.2 meters) wide that is
bolted down on top of the reactor to prevent any radioactive material
from escaping.
The corrosion was so severe that a stainless steel liner 3/8-inch (1
cm) thick inside the reactor was the only barrier left between the
reactor core, which operates under enormous pressure, and the metal
shroud surrounding the reactor vessel.
FirstEnergy representatives met on Wednesday with officials from the
NRC to discuss proposed repairs at the Davis-Besse plant. Agency
approval is needed before work could begin.
The company wants to cut the most damaged area at the top of the
reactor head and cover it with a stainless steel plate.
The plate would be 12 to 13 inches in diameter, about five inches
thick, and weigh between 300 to 400 pounds. It would be welded in
place using robotic equipment.

Radioactivity too high for housing development: Greens
April 13 - Australian Broadcasting Company - Greens MP Robin Chapple
says new testing of radiation levels at a waste disposal dump south
of Bunbury shows they are too high to allow housing in the near
vicinity.
Mr Chapple says the Dalyellup housing estate will come to within 25
metres of the dumps, which are still being rehabilitated by
Millennium Inorganic Chemicals.
The company can use the site until 2010.
Mr Chapple says he is not pinning the blame on the company, which has
complied with Environmental Protection Authority (EPA) guidelines.
However, he says it should be realised that erosion could one day
expose the radioactive material, which remains toxic for about
50,000 years.
"What I really come back to is the fundamental issue that the shire
and the EPA should not have allowed two totally different competing
usages to go next to each other, the area is allowed to continue to
take waste for a considerable amount of time at the same time as a
housing development is going up next to it," Mr Chapple said.
The Shire of Capel says it took advice from Government authorities
before approving the subdivision plans.
A spokesman for the Department of Environmental Protection says Mr
Chapple's concerns are being examined.
In the meantime, the developers have agreed not to develop land
within 75 metres of the disposal ponds.
