NRC urges U.S. nuclear plants be checked for leaks
WASHINGTON, Aug 9 (Reuters) - The Nuclear Regulatory Commission
Friday urged operators of U.S. nuclear power plants with pressurized
water reactors to further inspect the top of their reactors for
possible cracks and leaks.
The NRC said it issued the bulletin in response to cracked and
leaking nozzles found at several reactors and significant corrosion
discovered in the reactor vessel head at the Davis-Besse nuclear
power plant in Oak Harbor, Ohio.
Instead of relying only on visual inspections to find any problems,
the agency said reactor operators should also use ultrasound,
electric currents and liquid dyes to check for cracking and corrosion
in a reactor's metal head.
"Inspection programs that primarily rely on visual examinations may
need to be supplemented," the NRC said in a statement.
The NRC asked plant operators to file their future inspection plans
with the agency within 30 days.
During a scheduled refueling outage at the Davis-Besse plant last
February, the plant's engineers found boric acid had leaked at the
base of several of the control rod nozzles that penetrate the
reactor. The plant has been shut down since then.
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.
The 25-year-old Davis-Besse plant is owned by FirstEnergy Corp.
<FE.N>
Of the 103 nuclear reactors operating in 34 states, 69 facilities are
of the pressurized-water type.
With a pressurized reactor, water is kept in the reactor under high
pressure so it does not boil. The heated water flows from the reactor
through pipes to a nearby steam generator. The pipes are surrounded
by a second water supply that boils and produces steam to spin the
turbine generator and produce electricity.
The water then returns to the reactor, where it is reheated and sent
back to the steam generator in a continuos loop.
Agency staff will meet at NRC headquarters in Rockville, Maryland on
Aug. 23 with the Nuclear Energy Institute and power plant operators
to discuss the new inspection guidelines. The meeting is open to the
public.

U.S. Likely to Move N.M. Plutonium
WASHINGTON Aug 12 (AP) - Pending a final environmental review, the
Energy Department is expected to move as much as several tons of
plutonium and weapons-grade uranium from a federal research
laboratory in New Mexico to Nevada because of security concerns,
according to documents.
In a department memo, John C. Browne, director of the Los Alamos
National Laboratory, called the proposed move ``the best overall
decision to meet the post-September 11th challenges for the long-term
security of nuclear activities.''
An Energy Department spokesman, Bryan Wilkes, said that while no
final decision has been made, moving the material to the Nevada Test
Site is the preferred option being studied to increase security. The
environmental study is being reviewed, he said.
Several tons of highly enriched uranium and plutonium, which could be
used to make an atomic bomb, are kept at Technical Area-18 at the Los
Alamos lab in New Mexico where critics have said it cannot be
adequately protected.
``There is no doubt that that facility was at high risk. They simply
could not defend it,'' said Pete Stockton, an analyst for the Project
on Government Oversight, a private watchdog group that Sunday
released a copy of the Browne memo and other documents involving the
expected move.
Built in the 1940s, Technical Area-18 is located at the bottom of a
steep canyon, where the high ground and an adjacent highway makes the
site difficult to defend.
In repeated security exercises, troops have been unable to protect
the material. In a 1997 exercise, Army Special Forces posing as
attackers wheeled away a garden cart full of props representing the
nuclear material. In another test, attackers obtained access to the
facility where they could detonated an explosion, had they been
terrorists.
Had actual material been stolen it would have been enough to make
several weapons, said Stockton, who three years ago chaired a DOE
team that recommended to then-Energy Secretary Bill Richardson that
the material be moved. Richardson ordered the environmental studies
into moving the material.
Rep. Ed Markey, D-Mass., a frequent critic of security at federal
weapons facilities, urged the department to complete the move as
quickly as possible and safeguard the material from potential
terrorists.
POGO, which has criticized DOE security of nuclear weapons material,
obtained a draft press release from the National Nuclear Security
Administration, an agency within the DOE, that indicated that plans
are going forward to move the material to Nevada with a decision
anticipated next month.
Everett H. Beckner, deputy NNSA administrator, has given his approval
to begin design activities and other steps to implement the move,
according to a memo obtained by POGO.
The material is part of a research project in which scientists
examine how electronic components of nuclear weapons respond to
small, short-lived nuclear detonations.

Senator Questions Nuclear Plant Cleanup
Washington Aug 10 (Washington Post) A Senate Republican yesterday
demanded extensive records of the Department of Energy's dealings
with contractor Lockheed Martin Corp., questioning whether "cozy
relations" were impeding a government probe of alleged fraud and
environmental abuse at the agency's Paducah, Ky., uranium plant.
Sen. Charles E. Grassley (Iowa), the ranking Republican on the Senate
Finance Committee, was the second senior lawmaker in as many days to
publicly question the department's handling of the cleanup at
Paducah, a nuclear-fuel plant that became the focus of a federal
probe three years ago this month.
Although the department has acknowledged extensive environmental
damage at the Kentucky plant -- and even issued an apology to workers
-- it has not decided whether former plant operator Lockheed Martin
should be held financially responsible. A Justice Department decision
on whether to join a whistle-blower lawsuit against Lockheed has been
delayed for more than two years, in part because the department has
withheld its opinion on the merits of the case.
The lawsuit alleges that Energy Department contractors misled workers
and the government about environmental contamination at the plant,
built in 1952 to enrich uranium for nuclear bombs.
"I am troubled by the possibility that there may be a subtle effort
underway at the Energy Department to slow or even sideline" the
government's intervention in the case, Grassley wrote in a letter to
Energy Secretary Spencer Abraham.
Too often, he wrote, "I have seen agencies place a premium on cozy
relationships with their contractors . . . over and above the need to
protect taxpayers." Grassley asked Abraham to turn over three years'
worth of documents and memos between Energy officials and Lockheed.
Similar concerns were raised in a letter Thursday by Rep. Henry A.
Waxman (Calif.), the ranking Democrat on the House Government Reform
Committee. Waxman noted ties between Lockheed and the Bush
administration -- Vice President Cheney's wife, Lynne V. Cheney, is a
former Lockheed board member -- as well as the contractor's
reputation for lobbying and political giving.
"If a corporation has indeed caused this terrible harm at Paducah, it
would be outrageous to force the public to pay the bills three times
over -- first for contract fees, second in suffering the harm and
third for the cleanup," Waxman wrote.
The Energy Department yesterday promised to review the lawmakers'
concerns. "We are carefully considering all points raised and seeking
the views of all parties," department spokesman Joe Davis said.
Lockheed Martin has declined to talk about the specifics of the
whistle-blower case, but spokeswoman Meghan Mariman said
yesterday that the company has cooperated fully with government
investigators. "We believe the case has no merit," she said.
The apparent ambivalence over the whistle-blower case stands in sharp
contrast with the department's decisive steps in launching a
$1.3 billion cleanup and assisting ailing workers.
On Thursday, Abraham announced changes intended to make it easier for
workers to qualify for payments. "Employees of DOE
contractors have performed important work for their country," Abraham
said in announcing the rule changes. "Even though they may
have worked for a government contractor, these dedicated individuals
are our workers, and we are going to take care of them."

Lyle Borst, 89, Nuclear Physicist Who Worked on A-Bomb Project, Dies
New York Auh 12 (NY Times) Dr. Lyle B. Borst, a nuclear physicist who
helped build Brookhaven National Laboratory's nuclear
reactor and was an early member of the Manhattan Project, died on
July 30 at his home in Williamsville, N.Y. He was 89.
In 1950, Dr. Borst led the construction of the Brookhaven Graphite
Research Reactor, which was the largest and most powerful
reactor in the country and the first to be built solely for research
and other peacetime uses of atomic energy.
Within the first nine months of operating the reactor, Dr. Borst
announced that it had produced a new type of radioactive iodine,
which is used in treating thyroid cancer.
In 1952, based on studies of new types of atomic nuclei created in
the reactor, Dr. Borst helped explain the mystery behind giant
stars, known as supernovae, that burst with the energy of billions of
atomic bombs and flare for several years with the brilliance of
several million suns.
Dr. Borst found that beryllium 7, an isotope of beryllium that does
not occur naturally on earth, is formed in supernovae by the fusion
of two helium nuclei. The fusion takes place after the star has used
up its hydrogen supply. This reaction absorbs huge quantities of
energy, causing the star to collapse in the greatest cosmic explosion
known.
Dr. Borst was also a senior physicist at the Clinton Laboratories in
Oak Ridge, Tenn., where he worked on the Manhattan Project.
After atomic bombs were dropped in 1945 on Hiroshima and Nagasaki,
Dr. Borst, concerned that atomic energy should be
internationally regulated, helped organize a group of about 1,300
scientists who had worked on the bomb project and wanted to keep
atomic energy under civilian control, rather than military control,
to prevent a worldwide competitive armaments race.
Speaking in support of an atomic energy control bill in front of
Congress in 1945, Dr. Borst said he helped start the Federation of
Atomic Scientists "to create a realization of the dangers that this
nation and all civilization will face if the tremendous destructive
potential of nuclear energy is misused."
On a trip to Greece in 1961, Dr. Borst discovered that a "Manhattan
District Project" in Sparta made steel in large quantities as early
as 650 B.C.
Based on specimens he obtained from archaeologists, he theorized that
steel was the secret weapon of the Spartans and that it
was the reason for their military successes against enemies having
only soft iron or bronze weapons. Having such a weapon at that
time, Dr. Borst said in a 1961 article in The New York Times, was
almost the military equivalent of having an atomic bomb.
Born in Chicago on Nov. 24, 1912, Lyle Benjamin Borst earned
bachelor's and master's degrees at the University of Illinois and a
doctorate at the University of Chicago.
In 1942, Dr. Borst was a research associate at the metallurgical
laboratory in Chicago, where Dr. Enrico Fermi conducted the first
self-sustaining nuclear chain reaction.
He became a professor of physics at the University of Utah in the
early 50's and helped design the university's small nuclear reactor.
Dr. Borst taught at New York University and the State University of
New York at Buffalo, and was a member of the National Board of the
American Civil Liberties Union.
He is survived by his wife of 63 years, Ruth Barbara Mayer Borst; two
sons, John Benjamin, of Vancouver, British Columbia, and Stephen, of
North Brookfield, Mass.; a daughter, Frances Elizabeth Wright of
Albany; and seven grandchildren.
