Scientists affirm mass of neutrinos, corroborate Japan study
TOKYO, June 19 (Kyodo) - An international team of scientists from
Canada, Britain and the United States has found ''direct evidence''
proving that tiny subatomic particles called neutrinos have mass,
team members said Monday.
The findings on neutrinos, which have so far been shrouded in
mystery, were drawn from observations made at the Sudbury Neutrino
Observatory (SNO) near Sudbury in eastern Canada.
Neutrinos are produced in vast numbers by the sun and other
astrophysical objects due to nuclear fusion within the sun's
interior.
Members said the latest results, which study the presence of mass in
neutrinos from a different angle, corroborate earlier measurements of
the scattering of solar neutrinos from electrons in ordinary water
which were made three years ago by a team composed mainly of Japanese
scientists.
The first SNO results were detected through the SuperKamiokande
detector at the Institute for Cosmic Ray Research of the University
of Tokyo in Gifu Prefecture.
These combined data provided direct evidence of the phenomenon that
neutrinos oscillate, according to members.
Members said they have arrived at definitive results that electron
neutrinos from the sun transform into neutrinos of another type,
wherein such a transformation points to direct evidence that
neutrinos have mass.
They said that results showed that ''by combining this with
information from previous measurements, it is possible to set an
upper limit on the sum of the known neutrino masses.''
The SNO, located 2,000 meters under ground in a nickel mine, uses
1,000 tons of heavy water to detect all three types of neutrinos
including electron neutrinos.
Construction of the SNO laboratory began in 1990. Measurements at the
laboratory began in 1999, a year after its completion.

Antinuclear torch relay begins in Hiroshima
HIROSHIMA, June 19 (Kyodo) - An antinuclear torch relay that will
pass through all 86 cities, towns and villages in Hiroshima
Prefecture began Tuesday, with participants voicing hope that the
world will not experience war or nuclear attack in the 21st century.
The 12-member leadoff group of runners, including Kazuo Harada,
secretary general of a Hiroshima prefecture group to promote peace,
began the 20th relay from Hiroshima Peace Park at 8:15 a.m., the time
the U.S. dropped an atomic bomb on Hiroshima on Aug. 6, 1945, during
World War II.
About 40 people, including A-bomb survivors, observed a moment of
silence near the Cenotaph for the Atomic Bomb Victims during a
ceremony to commemorate the start of the relay.
According to organizers, the relay will cover about 1,816 kilometers
and end July 26, when the last batch of runners arrives at the park.
Some 10,000 locals are expected to participate in the event.

Ex-Nuclear Official Sues Over Book
WASHINGTON (AP) - A retired Los Alamos nuclear security official
filed a lawsuit Monday to try to force the government to allow the
release of his book on the Chinese nuclear weapons program.
For the last 18 months the government has blocked the publication of
Danny Stillman's book while various agencies scrutinize each line to
decide if it divulges national security secrets, according to his
attorney, Mark Zaid.
``We're not threatening to release classified information,'' Zaid
said. ``We're challenging the government to prove their case and we
don't think they're going to be able to do it.''
The suit against the Defense Department, Energy Department, Defense
Intelligence Agency and CIA was filed in U.S. District Court in
Washington. It alleges the agencies have violated their own rules for
classifying material and Stillman's constitutional right to publish
the book.
Defense Department spokesman Glenn Flood said the review of the
manuscript is continuing.
``We plan to do a thorough job. We're not going to rush it,'' he
said.
Stillman worked for 28 years at the Los Alamos National Laboratory in
New Mexico, 14 as the head of the intelligence division. He retired
in 1993.
Between 1990 and 1999, Stillman made nine trips to China, visiting a
nuclear test site and a nuclear lab, meeting with scientists and
attending lectures.
None of the trips was taken at the request of the U.S. government,
although he was voluntarily debriefed by government officials when he
returned.
Stillman took notes of his trips and compiled them into a 500-page
manuscript entitled ``Inside China's Nuclear Weapons Program.'' In
January 2000, Stillman turned over the manuscript to the government
for a security review - a prepublication condition imposed on any
government worker granted security clearance.
Since then, Stillman and his attorneys have pressed the Energy
Department and Defense Department to finish the review.
A Defense Department memo from last September said the Pentagon
objects to publication of any portion of the manuscript because of
security concerns. The memo also said publication could ``damage
American foreign relations with China,'' according to the lawsuit.
Zaid said that argument is absurd, since the Chinese scientists and
other officials in the program gave Stillman all of the information
for the book.
``This can't embarrass China, because the Chinese expected this
information to get (out),'' Zaid said.
In his book, Stillman argues that the Chinese weapons advances were
made without the benefit of espionage.
About the time Stillman finished his manuscript, Wen Ho Lee, a
Taiwanese-born Los Alamos scientist, was arrested amid fears of
Chinese espionage.
Lee was charged with 59 counts of illegally downloading nuclear
secrets, not espionage, and eventually pleaded guilty to one count of
mishandling information. A judge apologized for the nine months Lee
spent in solitary confinement, saying he had been misled by
prosecutors.
Steven Aftergood, a government secrecy specialist with the Federation
of American Scientists, said national security is not a blanket
excuse to limit free speech rights.
``It would be one thing that if they said there is this or that
detail that needs to be modified in the interest of national
security, but it is completely implausible to claim the entire
manuscript needs to be suppressed,'' he said.

N.Y. businesses say 10,000 MW of new power needed
NEW YORK, June 18 (Reuters) - As New York puts together a new Energy
Plan, the Business Council of New York advised the Energy Planning
Board to concentrate on adding at least 10,000 megawatts of electric
generating capacity within five years.
"Only by adding this capacity can New York sustain economic growth
and foster the robust competition in energy markets that will drive
energy costs down," Daniel Walsh, president and chief executive of
the statewide association of over 4,000 businesses, wrote to the
board in a letter released Monday.
The State Energy Planning Board is expected to release a draft
revision of its Energy Plan this fall, and today is the deadline for
public comments on the existing plan.
Statewide public hearings are to be conducted before the final
revision is adopted next spring.
The Energy Plan is an influential policy document, Walsh told the
Energy Board in the letter, adding that for this reason the board
should emphasize the need for more generating capacity.
The state will have a shortfall of 9,658 megawatts (MW) within five
years, based on past demand increases and recommendations from the
New York Independent System Operator, Walsh said.
But he said his business council recommends as much as 15,000 MW of
generation be added over the next five to seven years to "err on the
safe side" and avoid California-like power shortages and price
spikes.
New York's peak power demand in 2000 was 30,200 MW, Walsh said, and
assuming a five-year growth rate of 9.82 percent -- the same growth
rate New York experienced from 1995-2000 -- peak demands will grow by
2,965 MW.
Preserving an 18 percent margin needed for reliability will require
5,969 MW, and adding 15 percent of capacity to foster competition
would make an extra 5,870 MW necessary, bringing the total projected
shortfall to 9,658 MW, Walsh said.
Although New York has not replicated California's errors in
restructuring power markets, Walsh said, "the two states share this
fundamental similarity: demand for electricity has been growing
without new capacity being developed to meet it."
>From 1980-2000, New York's annual peak demand for electricity grew
5.1 times as much as the population, and 2.1 times as much as the
state's employment base, Walsh said.
During the same 20-year period, peak demand grew by roughly 1,000
more megawatts than the state added in new generating capacity, he
said, adding from 1995-2000 demand grew by 2,700 MW, but the state
added only 293 MW of new capacity.
The business council also recommended the state streamline and
accelerate its new plant siting process and upgrade the electricity
transmission systems.
Also, Walsh said New York must upgrade its natural gas pipelines to
meet increasing demand for the fuel, and said that power plants run
by a range of fuels, including natural gas, coal, oil, and nuclear
power, are needed to protect consumers and businesses from volatility
in natural gas markets.
Energy efficiency and energy conservation programs must also be
emphasized, Walsh said.

Kazakhstan mulls storing foreign nuclear waste
ASTANA, June 18 (Reuters) - A senior Kazakhstan official said on
Monday the vast but sparsely populated Central Asian state might
boost revenues by burying imported low-radioactivity nuclear waste on
its territory.
Mukhtar Dzhakishev, head of the state nuclear firm Kazatomprom, told
parliament that Kazakhstan might earn $30-40 billion in the next 25
to 30 years by storing foreign nuclear waste.
Kazakhstan is the size of Western Europe but has a population of only
15 million.
"This is a very lucrative business, and we may arrange deals under
which the government receives annual bonuses worth $200-500 million,"
Dzhakishev told deputies.
He said large amounts of waste could be buried in existing open-cast
uranium mines in the western Mangistau region and sophisticated
storage technology would not be needed.
"Barrels with compressed low-radioactivity waste are received, put in
pits and covered with soil, and there is no radiation on the
surface," he said.
Dzhakishev said Kazakhstan did not possess technology which would
allow it to process and store high-radioactivity waste, but it could
easily handle low-radioactivity waste like gloves, overalls, and
other material from foreign nuclear power plants.
It was not immediately clear whether or when the government would
submit a draft law to parliament. Dzhakishev gave no time frame or
details of possible deals with foreign nuclear plants.
Earlier this month the lower chamber of the Russian parliament
adopted a bill that is likely to open Russia to imports of spent
nuclear fuel.
The bill, expected to be passed into law, has been given a hostile
reception by environmentalists and the public in Russia who say it
could turn the country into a nuclear dump.
Environmental concerns are also strong in Kazakhstan, whose
northeastern Semipalatinsk region underwent hundreds of atmospheric,
surface and underground nuclear tests in 1949-89.
The Soviet-era tests are blamed by scientists for a rising number of
cancer cases and birth defects among local people.

TEPCO to close reactor due to cooling water leak
TOKYO, June 18 (Reuters) - Tokyo Electric Power Co Inc (TEPCO) said
on Monday it will temporarily shut down a 1.356-gigawatt nuclear
reactor in northern Japan after it found cooling water had leaked
from a tank.
TEPCO, Japan's largest power company, said no radiation had escaped
into the environment from the Kashiwazaki-Kariwa power plant's No 6
reactor as a result of the incident.
TEPCO will manually close the reactor late on Monday for checks and
repairs, the company said, adding that the leak occured in a place
unrelated to the operation of the reactor.
The company did not say when the reactor would restart.
Japan has 51 commercial nuclear reactors, which provide about one-
third of the country's power.
The industry has been criticised for a series of accidents, including
Japan's worst-ever at a uranium-processing plant in Tokaimura, north
of Tokyo, in 1999 that killed two workers.

Aomori gov. vows to continue accepting spent nuclear fuel
AOMORI, Japan, June 18 (Kyodo) - Aomori Gov. Morio Kimura said Monday
he will continue to allow the shipment of spent nuclear fuel to a
reprocessing facility in the village of Rokkasho in the northeastern
Japan prefecture.
Kimura made the remarks after meeting with Economy, Trade and
Industry Minister Takeo Hiranuma at the prefectural government office
over the so-called ''pluthermal'' project, which involves the use of
plutonium-uranium mixed oxide (MOX) fuel, and national atomic energy
policies, local government officials said.
Kimura said at a press conference after the meeting that the
prefectural government will continue to have spent nuclear fuel
delivered to the facility, which is currently under construction in
the village and is scheduled to start reprocessing in July 2005.
During their meeting, Kimura asked Hiranuma whether the central
government will change its policy of promoting the pluthermal project
in the wake of last month's plebiscite in the village of Kariwa in
Niigata Prefecture, in which a majority of local residents voted
against the use of MOX fuel at a nuclear power plant straddling their
village and Kashiwazaki city, the officials said.
Hiranuma responded that the government will make further efforts to
seek public understanding on the pluthermal project and asked for
cooperation and understanding from Aomori Prefecture on the issue,
the officials said.
Under the pluthermal project, the government and power companies plan
to use MOX fuel in light-water reactors. The fuel is made by mixing
uranium with plutonium extracted from spent nuclear fuel. The word
pluthermal combines the words plutonium and thermal.
Kimura also told Hiranuma that he hopes the International
Thermonuclear Experimental Reactor (ITER), an international project
jointly planned by Japan, several European nations and Russia, will
be built in the prefecture, according to the officials.

Grass Could Endanger Nuke Reservation
RICHLAND, Wash. (AP) - Blackened Rattlesnake Mountain is green again,
a year after the largest fire in Washington state threatened
radioactive waste storage areas at Hanford nuclear reservation and
burned 11 homes in nearby Benton City.
Unfortunately, a lot of that green, green grass of spring is an
invader species called cheat grass, with the potential to boost fire
danger at Hanford again this summer.
``The cheat grass is bad news. It is the scourge of the West,'' said
Greg Hughes, a project leader for the U.S. Fish and Wildlife Service,
which manages the Hanford Reach National Monument, including the Arid
Lands Ecology Reserve.
The fast-moving, 163,000-acre Hanford fire was sparked by a fatal
traffic collision last June 27 on the northwestern edge of the
reservation, where plutonium was once made for the nation's nuclear
arsenal.
It was a scorching summer day, with plenty of grass and sagebrush to
burn in the arid desert country of south-central Washington. Steep
slopes made firefighting difficult.
``The fire blew up. It came roaring out of the canyon. The wind and
fuel and heat forced it down the face of the mountain,'' Hanford Fire
Chief Don Good said.
At one point, the flames traveled an almost unheard of 20 miles in 90
minutes, Good said. ``This fire had all the elements that you don't
want to happen all at one time,'' he said.
Some 850 firefighters and support staff from around the Northwest
were called to help the 106-member Hanford Fire Department.
The flames moved perilously close to Hanford's 200 West Area, where
some of the most deadly radioactive waste here at the most-
contaminated nuclear site in the country is stored in underground
tanks and pits.
Firefighting activities are believed to have released minute amounts
of radioactive elements into the air, elevating readings at
monitoring sites around the 560-square-mile reservation, which is
owned by the U.S. Department of Energy.
Within reservation boundaries, the biggest environmental casualty was
the 77,000-acre Arid Lands Ecology Reserve - an uncontaminated
portion of Hanford that is home to hundreds of elk and the rare and
fragile shrub-steppe ecosystem. The reserve burned, some elk suffered
burn injuries or fled and a few died in the fire.
But time and nature have transformed the Rattlesnake Hills on the
reserve, and though charred sticks that once were sagebrush still
poke out of the dirt, the area is now briefly verdant with grasses,
pink phlox and purple lupine.
Native plants are relatively resistant to fire in the Columbia Basin,
which gets only about 7 inches of rain and snow each year. Summer
temperatures that top 100 degrees are not uncommon.
But when the land is disturbed, the native habitat is degraded,
inviting such invader species as cheat grass and Russian thistle,
also known as tumbleweed, said Larry Cadwell, a staff scientist at
the Pacific Northwest National Laboratory.
``Each time we have a fire, we lose some element of native grasses,''
he said. ``Sixty percent of the 15 million acres of shrub-steppe in
the entire Columbia Basin is gone.''
Hanford's native grasses are bunch grasses, which grow just as their
name indicates, in clumps separated by bare patches of dirt. Cheat
grass grows in a more continuous mat that aids the spread of fire.
``Cheat grass is a ladder fuel that brings fire up into the sage like
a candle, ... and cheat grass is like gasoline next to the highway,''
Hughes said.
Through the Burned Area Emergency Rehabilitation plan, the Fish and
Wildlife Service is working to control invader species such as cheat
grass by chemical and mechanical means.
It is a high-tech form of weeding, using global positioning satellite
data and aerial photography to identify sites for monitoring and
control.
While the goal is total eradication, cheat grass, much like
tumbleweeds, was already well-established before the fire.
``On the ALE (reserve), the plan would be to wipe out as much cheat
grass as we can, and plant native grass as needed if it doesn't come
up naturally,'' Hughes said.
``Because of this fire, the invasion of nonnatives has been
accelerated. We can't continue to go out and put Band-Aids on little
pieces and watch it get reinvaded by cheat grass and invasive weed
species.''
The price tag for revegetation is high - $6.5 million - and it is
still undetermined how much money would be available for restoration,
Hughes said.
The Fish and Wildlife Service has planted on the reserve about
150,000 sagebrush seedlings that were scheduled for planting before
the fire.
Because the reserve is a research site, the invasion of alien plant
life also is seen as a learning opportunity, and the Fish and
Wildlife Service has hired a specialist to monitor the effects of the
fire on the Hanford vegetation.
Off the reserve and on Hanford's central plateau, some replanting
also is under way, but high winds and the dunelike nature of parts of
the burned area have made that a challenge, said Ray Johnson, a
biological control manager at Fluor Hanford, the contractor managing
the site for the Energy Department.
Crews have been planting and in some areas, replanting, bunch grasses
on 1,000 acres around the 200 West Area, where dust from the burned-
over area has been so bad that workers sometimes are sent home by
midday.
``The winds have been absolutely brutal on those,'' Johnson said.
``We had excellent growth as early as last fall, then we had 50 to 70
mile an hour winds. The young grass didn't survive that well. The
moving sand either shears the young grass off or else will cover it
up.''
Fluor is looking for innovative ways to help young grasses survive
and is considering, among other things, sprinkle irrigation to get
the plants established.

Robot Could Protect Nuke Workers
RICHLAND, Wash. (AP) - Some waste pits at the Hanford nuclear
reservation are so hot they emit in only one hour a dose of radiation
100 times higher than the amount workers are allowed to receive in a
year.
But the pits must be cleaned and many of them upgraded for
transferring radioactive waste from Hanford's underground tank farms
to a vitrification plant now being designed to turn some of the
deadly material into glass logs for long-term storage.
In response to the dangers, the Pacific Northwest National Laboratory
has designed the ``Pit Viper,'' a versatile, robotic arm and remote
video monitoring station that will allow workers to rehabilitate
contaminated pits without getting near them.
Pit work exposes handlers to more radiation than any other cleanup
task at the tank farms, where nearly 54 million gallons of highly
radioactive waste are stored in 177 aging and leak-prone tanks.
Even workers standing near some pits can be exposed to their annual
limits of radiation in a few hours or a few days, said Don Niebuhr, a
field work supervisor for the CH2M Hill Hanford Group, which manages
the tank farms.
``Doing this work is extremely hazardous. It is the most dose-
intensive task,'' said Sharon Bailey, Pit Viper project manager for
the laboratory. ``We expect this (Pit Viper) may reduce personnel
dose rates by up to 75 percent.''
The lab recently showed off a prototype Pit Viper, a $1 million
system that will be used at the reservation this summer. The three-
joystick control board and four monitors in the control trailer look
deceptively simple.
``That's the idea,'' said Carl Baker, a senior development engineer
for the lab. ``We want this to be actually used.''
An operator, working as far away as 200 feet, has views from four
cameras showing what the robotic arm is doing. It can lift as much as
200 pounds.
``We have 600 equipment pits that need to be cleaned up before we can
proceed with vitrification,'' said Paul Kruger, the U.S. Department
of Energy's associate manager for science and technology in Richland.
The swimming pool-like pits average about 8 feet-by-10-feet in area
and 8 feet deep. Some pits record radiation dose rates so high that
prep work with shields and other protective devices is required
before workers can enter, Niebuhr said.
There are no plans to use the Pit Viper at other Energy Department
sites - no other site has this particular problem - but if other
sites saw potential use, the lab would work on modifications.
CH2M Hill would like to have about six Pit Vipers for its work, said
Rick Raymond, the company's vice president for projects.
Whether the money would be available is unknown.
If funding can be found for the Pit Vipers, the pits can be cleaned
out more safely and more efficiently, eventually saving money,
Raymond said.
The Bush administration has budgeted for the Energy Department's
Office of River Protection $814 million for fiscal year 2002. The
office, which oversees the tank farms and the glassification project,
needs $1.1 billion to meet its contract obligations.
The vitrification plant is expected to be up and running in 2007.
