Reid considering bill to make Yucca Mountain dump obsolete
SALT LAKE CITY (AP) - The U.S. Senate's minority leader is
considering a bill that would make a nuclear waste dump at Nevada's
Yucca Mountain - and a temporary holding spot for the waste in Utah -
obsolete.
Sen. Harry Reid, D-Nev., plans to introduce legislation within the
next few weeks that would authorize the Energy Department to assume
ownership of the spent nuclear waste stored at reactors and store it
at the facilities, The Salt Lake Tribune reported Saturday.
"This is the right thing to do and I look forward to discussing this
option with my colleagues," Reid said.
Reid has been working for years to block the Yucca Mountain
repository from being built in his state, but the prospects for this
plan are uncertain since it runs counter to the stated desires of
President Bush, Congress and the nuclear energy industry, all of whom
want the Yucca repository built.
Reid said on-site storage could mean that Yucca and a proposal by
Private Fuel Storage, a consortium of nuclear power generators, to
temporarily store 40,000 tons of waste on the Skull Valley Goshute
Indian reservation in Utah's west desert, about 45 miles southwest of
Salt Lake City, would not be needed.
Joseph Egan, an attorney fighting Yucca Mountain on behalf of the
Nevada Agency for Nuclear Projects, told The Tribune it is possible
that moving ahead with Reid's on-site storage plan would make the PFS
facility unnecessary.
Utah officials have feared that if the waste would be safe to ship
and store in Utah, it should also be safe left where it is.
After meeting with White House Chief of Staff Andrew Card on
Wednesday, Utah Republican Sens. Orrin Hatch and Bob Bennett endorsed
the administration's position of building the repository, saying the
best way to block the PFS site is to make sure Yucca Mountain is
built.
"They are committed to a strategy of straight to Yucca. Straight to
Yucca means not stopping in Skull Valley," Bennett said Wednesday.
Gov. Jon Huntsman will go to Washington this week to meet with Bush
administration officials about several issues, including the state's
opposition to the nuclear-waste plan.
The new effort comes after the Atomic Safety and Licensing Board
rejected the state's argument that there was an unacceptable risk
that a fighter from Hill Air Force Base could crash into the waste
site and release radioactive material.
The state has asked the board to reconsider its decision. If that
fails, the Nuclear Regulatory Commission will decide whether to
license the facility.
Bush has requested $651 million in the coming year to work on Yucca
Mountain, which is about half of what was projected for work on the
facility. But Energy Department officials say the administration
remains committed to seeing the project completed, even if it is done
behind schedule.
"We believe it's necessary and we are committed to moving forward
with the plan to build the repository" at Yucca Mountain, said Energy
Department spokesman Joe Davis.

Entergy scales back size of nuke waste facility
MONTPELIER, Vt. (AP) - Entergy Nuclear has scaled back the size of a
proposed high-level radioactive waste facility in Vernon, according
to draft legislation proposed to the House Natural Resources and
Energy Committee.
Rep. Robert Dostis, D-Waterbury, chairman of the committee, said
Friday that Entergy's proposal was a first step toward breaking the
regulatory and legislative logjam over the controversial waste
project.
Entergy has asked for legislative approval to build a facility to
store spent nuclear fuel in 12 casks, but last month it told the
Windham Regional Commission it wanted to build a facility to
accommodate 36 casks.
Robert Williams, spokesman for Entergy, refused to comment on the
apparent scaling back of the project. "I'm not in a position to
comment on the language," Williams said.
Dostis said his committee would be seeking an annual payment from
Entergy in exchange for the state hosting the high-level radioactive
waste facility.
Only two states in the country have legally wrangled some kind of
oversight on nuclear waste - Vermont and Minnesota - and Minnesota
receives an annual payment of $12 million, Dostis said.
"It's very appropriate for us to charge fees," he said, noting the
money would be earmarked for renewable energy, energy efficiency and
conservation programs.
Entergy is running out of storage space for the highly lethal old
nuclear fuel and says without legislative approval for the waste
facility, it would have to shut down the Vermont Yankee nuclear plant
in 2007 or 2008. The nuclear utility's supporters say that the
reactor provides one-third of all the electricity needed in Vermont,
and at a relatively low price of just under 4 cents per kilowatt
hour.
Entergy has maintained that it should be exempt from any legislative
oversight.
The current law gives Vermont Yankee Nuclear Power Corp. an exemption
from state legislative review. But that corporation no longer owns
Vermont Yankee. Entergy wanted "corporation" changed to "plant."
Dostis said his committee would hold public hearings in Windham
County as well as Montpelier, to gauge public concern on the issue.

Atomic museum in Las Vegas traces history of weapons development
LAS VEGAS (AP) - It's chilling to walk by a dented Army helmet with
big tinted goggles on the brim, a frayed "atomic cocktail" recipe
book and then come face to face with a family of mannequins, frozen
in time in a fallout shelter.
Baby boomers will recognize the Civil Defense character Bert the
Turtle and know by heart the instructions droning in black-and-white
on the family's boxy Packard Bell TV: When sirens sound, find
shelter. Don't look at the light. Duck and cover.
A digital countdown across the way tells when the steel doors of a
cement-walled Ground Zero Theater will open.
Curators of the new Atomic Testing Museum hope the setting stirs the
imagination for those with no memory of mushroom clouds and the role
the Nevada Test Site played in the development of nuclear deterrence.
"Nuclear weapons aren't gone," museum Director William Johnson says
as he leads the way through the $3.5 million (2.6 million) facility
that opened last month just east of the Las Vegas Strip. "The world
is just a different place now."
The museum traces a half-century of nuclear weapons testing in a
nation that grew to love or hate the bomb. It describes developments
that let scientists peer into the first millionth of a second of a
nuclear blast before instruments vaporized, and it charts research
that continued after earthshaking explosions ended in 1992 at the
test site.
It also has drawn criticism as revisionist history among advocates
who call it a forum for nuclear apologists, and it has reopened
wounds for "downwinders" sickened by fallout from atmospheric atomic
blasts.
"Once you've been a victim of nuclear weapons you're less
enthusiastic about it," said Michelle Thomas, 52, a lifelong resident
of St. George, Utah. "I don't hate or fear anyone bad enough to want
to see happen to them what happened to us."
Johnson doesn't deny that testing caused problems. He points to
exhibits describing the plight of downwinders and of test site
workers sickened by silicosis, and to a reading room and nuclear
testing archive containing more than 310,000 documents.
"I want people to come here and learn," he says. "But if there's only
one message taken away, it's that the Cold War was a war. It was a
struggle with the Soviet Union."
The story is told with a timeline, artifacts, interactive and touch-
screen displays and several films, including the 10-minute
presentation in the Ground Zero Theater.
Visitors sit on varnished wooden seats modeled after the warped,
weathered benches still on News Nob, a rocky outcrop overlooking
Yucca Flat where journalists observed atmospheric nuclear tests
beginning with "Charlie" in April 1952.
Light bursts as the big screen shows a nuclear test. The room rumbles
with embedded speakers. Air blasts tousle the hair, imitating a shock
wave.
"It's almost like you're sitting there. That's real stuff to me,"
says Mike Margalski, 49, a maintenance engineer who wants to
experience what his father did as an Army soldier exposed to more
than one nuclear test in the early 1950s. Eugene "Geno" Margalski
died of prostate cancer in 1996, at age 65.
"My dad never ever talked about it until just a few days before he
passed away," Margalski says. "He talked about going out and walking
in it while they came around with Geiger counters."
But this is no theme park. It is as somber as the 230,000 deaths and
injuries in Hiroshima and Nagasaki, Japan, in August 1945; as sober
as the concept of "mutually assured destruction" that shadowed the
world for half a century afterward.
The entry to the 8,000-square-foot (720-square-meter) museum
resembles a guard gate. Up a gentle ramp is a copy of Albert
Einstein's August 1939 letter to President Franklin Roosevelt
suggesting that uranium might yield "a new and important source of
energy."
An inert model of the most common B61 nuclear bomb - 12-feet-long
(3.6-meter-long), gray, unimposing - rests on its side next to
displays of the "Little Boy" and "Fat Man" devices dropped on Japan.
Through a 10-foot (3-meter) diameter steel "decoupler" portal and
down a tunnel lined with faux rock is the underground testing
gallery. Visitors whisper when they stop to reflect or remember.
Some exhibits have a "gee-whiz" element - chronicling how scientists
tested nuclear rocket engines, shrank the size of nuclear devices and
measured the effects of radionuclides on plants, animals and food.
This being Las Vegas, the museum also chronicles how tourists sipped
cocktails on casino rooftops, gazing at blast clouds on the horizon
at the test site, 65 miles (105 kilometers) to the northwest.
The museum, a partnership between the Nevada Test Site Historical
Foundation and the Desert Research Institute, is an affiliate of the
Smithsonian Institution.
Administrators foresee schoolchildren marveling at the column of
instruments used to measure underground nuclear explosions, working a
manipulator arm like the one scientists used to handle radioactive
materials and hearing the clicks of a Geiger counter measuring low-
level radioactivity.
"I would hope they come away with an understanding of what is
radiation and why we did testing," says Loretta Helling, a former
Energy Department public affairs specialist who spent eight years
curating the collection. "We try to have a balanced view in there."
Preston Truman foresees the museum ignoring unpleasantries while
teaching "that everything was good and beneficial and that America
won the Cold War."
"In 50 years, when all the people who had a negative opinion are
dead, it will be just that - one-sided history," says Truman, who
founded and directs an advocacy group called Downwinders.
The 53-year-old Truman's first memory as a child is sitting on his
father's knee in Enterprise, Utah, watching a mushroom cloud at the
Nevada Test Site. He figures that was 1955, a year in which the
government conducted 18 atmospheric tests.
"We're children of the bomb. We saw the flash. We heard the bangs. A
couple of times, the shock waves broke out windows that they paid
for," he says. "We got radiated and we got lied to."
Thomas remembers a fine ash falling like snow across St. George. When
fallout warnings sounded, her mother would don an old straw hat, pull
on rubber dish gloves and tie a dish towel around her own mouth to
pluck laundry from the outdoor drying line.
"She would wash the sheets twice in hot water so her kids wouldn't
have to sleep with radioactive fallout," Thomas says.
But Thomas began to develop maladies as a junior in high school:
ovarian cysts, breast cancer, a benign salivary gland tumor. She was
diagnosed in 1974 with polymyositis, an autoimmune system disease
similar to lupus. She and two siblings each received a one-time
"downwinder" payment of $50,000 (38,000) under the Radiation Exposure
Compensation Act of 1990.
"I think we've learned that the government is fallible and may not be
entirely upfront," Thomas says. "But it was considered unpatriotic in
those days to question the government."
Johnson, 47, recalled hearing the wail of Friday morning Civil
Defense sirens as a child in Miami.
He says the museum tried to put the nation's 1,054 above- and below-
ground nuclear tests in context. Of the 928 detonated at the test
site, 100 were atmospheric tests. Seven tests were exploded elsewhere
in Nevada, three each in New Mexico and Alaska, two each in Colorado
and Mississippi and 106 on Pacific islands. Three tests were
conducted on South Atlantic islands.
The number of nuclear tests peaked at 96 in 1962 - the year the
United States and the Soviet Union stared each other down with their
fingers on the button during the Cuban missile crisis.
"The paradigm of the 1950s, 1960s and 1970s was that the Northern
Hemisphere was going to be blown to bits," Johnson recalls. The
scientists, technicians and administrators at the test site, he says,
"were thinking they were saving the world."

NASA Finds Safe Zone in Earth's Radiation Belt
WASHINGTON, March 8 /PRNewswire/ -- Lightning in clouds, only a few
miles above the ground, clears a safe zone in the radiation belts
thousands of miles above the Earth, according to NASA-funded
researchers. The unexpected result resolves a forty-year-old debate
as to how the safe zone is formed, and it illuminates how the region
is cleared after it is filled with radiation during magnetic storms.
The safe zone, called the Van Allen Belt slot, is a potential haven
offering reduced radiation dosages for satellites that require Middle
Earth Orbits (MEOs). The research may eventually be applied to remove
radiation belts around the Earth and other worlds, reducing the
hazards of the space environment.
"The multi-billion-dollar Global Positioning System satellites skirt
the edge of the safe zone," said Dr. James Green of NASA's Goddard
Space Flight Center, Greenbelt, Md. He is the lead author of the
paper about the research published in the Journal of Geophysical
Research. "Without the cleansing effect from lightning, there would
be just one big radiation belt, with no easily accessible place to
put satellites," he said.
If the Van Allen radiation belts were visible from space, they would
resemble a pair of donuts around the Earth, one inside the other,
with the planet in the hole of the innermost. The Van Allen Belt slot
would appear as a space between the inner and outer donut. The belts
are comprised of high-speed electrically charged particles (electrons
and atomic nuclei) trapped in the Earth's magnetic field. The Earth's
magnetic field has invisible lines of magnetic force emerging from
the South Polar Region, out into space and back into the North Polar
Region. Because the radiation belt particles are electrically
charged, they respond to magnetic forces. The particles spiral around
the Earth's magnetic field lines, bouncing from pole to pole where
the planet's magnetic field is concentrated.
Scientists debated two theories to explain how the safe zone was
cleared. The prominent theory stated radio waves from space,
generated by turbulence in the zone, cleared it. An alternate theory,
confirmed by this research, stated radio waves generated by lightning
were responsible. "We were fascinated to discover evidence that
strongly supported the lightning theory, because we usually think
about how the space environment affects the Earth, not the reverse,"
Green said.
The flash we see from lightning is just part of the total radiation
it produces. Lightning also generates radio waves. In the same way
visible light is bent by a prism, these radio waves are bent by
electrically charged gas trapped in the Earth's magnetic field. That
causes the waves to flow out into space along the Earth's magnetic
field lines.
According to the lightning theory, radio waves clear the safe zone by
interacting with the radiation belt particles, removing a little of
their energy and changing their direction. This lowers the mirror
point, the place above the polar regions where the particles bounce.
Eventually, the mirror point becomes so low; it is in the Earth's
atmosphere. When this happens, the radiation belt particles can no
longer bounce back into space, because they collide with atmospheric
particles and dissipate their energy.
To confirm the theory, the team used a global map of lightning
activity made with the Micro Lab 1 spacecraft. They used radio wave
data from the Radio Plasma Imager on the Imager for Magnetopause to
Aurora Global Exploration (IMAGE) spacecraft, combined with archival
data from the Dynamics Explorer spacecraft. IMAGE and Dynamics
Explorer showed the radio wave activity in the safe zone closely
followed terrestrial lightning patterns observed by Micro Lab 1.
According to the team, there would not be a correlation if the radio
waves came from space instead of Earth. They concluded when magnetic
storms, caused by violent solar activity, inject a new supply of high-
speed particles into the safe zone, lightning clears them away in a
few days.
Engineers may eventually design spacecraft to generate radio waves at
the correct frequency and location to clear radiation belts around
other planets. This could be useful for human exploration of
interesting bodies like Jupiter's moon Europa, which orbits within
the giant planet's intense radiation belt.

Laboratory building reopens after radiation evacuation
OAK RIDGE, Tenn. (AP) - An evacuated nuclear processing building at
the Oak Ridge National Laboratory reopened Thursday, although a room
where radiation set off alarms remained closed, officials said.
Fifteen people were evacuated from Building 7920 and others were
ordered to take "shelter in place" after two continuous air
monitoring alarms sounded on Wednesday.
The building reopened Thursday and a recovery team was working to
restore normal operations in the laboratories section of the
building, a Department of Energy statement said.
"The room where radiation monitors triggered alarms Wednesday remains
closed, except for authorized personnel conducting recovery
operations," DOE said. "The room is used for storage and transfer of
radioactive materials and is normally limited access only."
DOE said no one was contaminated, there were no immediate health
concerns and there was no radioactive release into the environment.
The facility chemically processes highly radioactive materials
retrieved from the lab's High Flux Isotope Reactor, the world's most
powerful research reactor. The reactor, which has been out of service
since last month, produces isotopes for medical use and science.
The Oak Ridge laboratory, about 20 miles west of Knoxville, is DOE's
largest science and energy lab, comprising hundreds of buildings and
employing more than 3,800 people.

Nordic authorities advise against use of tanning beds, citing skin
cancer risk
OSLO, Norway (AP) - Nordic authorities on Monday advised against the
use of solariums, saying such tanning machines increase the risk of
skin cancer.
Children, young people and those with fair skin are at the greatest
risk, said the 11-page warning against sun beds issued jointly by
Norway, Sweden, Denmark, Finland and Iceland, all of whom have many
citizens with light skin and hair.
"The greatest cause of the increasing instances of skin cancer in the
Nordic region is believed to be excessive sunbathing," said a news
release from the Norwegian Radiation Protection Agency.
"The use of solariums is not recommended," the statement continued.
"The use of solariums increased the risk of skin cancer."
The report said people between 16 and 24 years of age are the biggest
users of sun beds. It also said children and adolescents may be the
most susceptible to the harmful effects of ultraviolet radiation,
including the most the most lethal type of skin cancer, melanoma.
The report also urged new rules for makers of solariums, requiring
greater safety features, and that those operating tanning centers
should have enough knowledge about potential risks to help their
customers make informed decisions.
"If sun beds are used, it is necessary to keep the annual UV dose low
and to provide users with all information necessary to minimize skin
damage and other health hazards," the report said.
In October, the Journal of the National Cancer Institute in the
United States published similar findings, after an extensive study by
international researchers.
They found that women of any age or hair color who regularly visited
tanning salons once or more per month increased their chance of
developing melanoma by 55 percent.
The Nordic warning was made jointly by the Danish National Board of
Health, the Finnish Radiation and Nuclear Safety Authority, the
Icelandic Radiation Protection Institute, Swedish Radiation
Protection Authority, as well as the Norwegian authority.
