Tougher Inspections Urged at Nuke Plants
WASHINGTON (AP) - Federal regulators told operators of the nation's
nuclear power plants to conduct tougher inspections beginning this
week in response to acid corrosion found on the reactor cap at an
Ohio plant.
All 69 plants with pressurized water reactors, including Davis-Besse
in northwest Ohio, must add either chemical or ultrasonic tests to
visual inspections for cracks or leaks in reactor heads. Plants
identified as being at high risk of acid corrosion must perform the
tests more often.
The order arose from the Nuclear Regulatory Commission's internal
investigation of how it handled corrosion at Davis-Besse, the
agency's chairman, Richard Meserve, told a Senate Environment and
Public Works subcommittee Thursday.
Years of visual inspections at the plant, operated by FirstEnergy
Corp. of Akron, Ohio, missed boric acid leaks that nearly ate through
the 6-inch-thick steel cap that covers the reactor vessel.
The plant has been shut down since February 2002, when it was closed
for maintenance. The corrosion was discovered last March.
Both the NRC and FirstEnergy made mistakes in looking for boric acid
corrosion on plant reactor heads, Meserve said. The hole at Davis-
Besse could have been prevented and FirstEnergy's actions before its
discovery were ``unacceptable,'' he told members of the subcommittee
on Clean Air, Climate Change and Nuclear Safety.
Sen. George Voinovich, who leads the subcommittee, challenged the NRC
commissioners on what they are doing with regard to restarting the
plant in Oak Harbor, Ohio, and to ensure plant safety nationwide.
``That the plant's safety could have been compromised really troubles
me,'' said Voinovich, R-Ohio.
The commissioners said safety mechanisms would have prevented a
catastrophe at Davis-Besse despite reported flaws in the reactor's
coolant system, which protects against a meltdown. The current system
is susceptible to clogging and commissioners are working with the
plant to improve it, they said.
``There was not an impending disaster,'' commissioner Nils Diaz said.
``It might not have been perfect, but they were there.''

Over 40 sites chosen for Japan nuclear-waste disposal
GIFU, Japan, Feb. 14 (Kyodo) - The predecessor of the state-run Japan
Nuclear Cycle Development Institute selected more than 40 areas from
12 prefectures as candidate sites for disposal of high-level
radioactive wastes in the late 1980s, a citizens group said Thursday.
The candidates sites picked by the Power Reactor and Nuclear Fuel
Development Corp. (Donen) from 1986 to 1988 were in Hokkaido, Akita,
Yamagata, Fukushima, Niigata, Nagano, Gifu, Ehime, Kochi, Nagasaki,
Miyazaki and Kagoshima, according to a Donen report obtained by the
group, called the Citizens Net Gifu.
The Japan Nuclear Cycle Development Institute said it is not bound by
the report, but members of the antinuclear group expressed concerns
that the candidates sites will emerge again if the institute has
difficulties choosing disposal sites.
While the citizens group obtained the report under the information
disclosure law, the institute declined to disclose the names of
candidate municipalities.
The group plans to file a suit to seek full disclosure of the report,
its members said.
The report said Donen picked sites of 3-5 square kilometers after
studying results of aerial photos and geological survey to make sure
they are not close to active faults or residential areas.
Donen planned to reach a decision on the sites but under a 1987 state
program for development and utilization of nuclear energy it was
excluded from making the final choice.
At present, the Nuclear Waste Management Organization is soliciting
disposal sites nationwide, but no municipalities have put themselves
forward so far.

U.S., China to join thermonuclear reactor project
TOKYO, Feb. 13 (Kyodo) - The United States and China will join Japan,
the European Union (EU), Russia and Canada in a major international
project to generate electric power through nuclear fusion, Japan's
education ministry said Thursday.
Representatives of the two countries will attend an intergovernmental
meeting in St. Petersburg next Tuesday and Wednesday, the Ministry of
Education, Culture, Sports, Science and Technology said.
Representatives from Japan will include Aomori Gov. Morio Kimura, who
is expected to press the group to build an experimental reactor in
the village of Rokkasho, Aomori Prefecture in his northeastern Japan,
Japanese officials said.
The international group has finished technical assessments on
candidate sites for the construction and operation of an
international thermonuclear experimental reactor (ITER). Such sites
include locations in France, Spain and Canada as well as Rokkasho.
At the upcoming meeting, group members will begin deliberations on
each participant's share of funding for the project, the ministry
said.
Last month, the U.S. announced its decision to rejoin the project,
shortly after China expressed its desire to participate.
The U.S. withdrew from the project in 1999, citing the project's
costs among other concerns.
ITER would be the first fusion device to produce a burning plasma and
to operate at a high power level for sustained periods of time.
Since the U.S. pullout in 1999, Japan, Russia and the EU have
redesigned the proposed experimental reactor and come up with a new
plan that would cut costs in half.
The three parties had been urging the U.S. to rejoin the project.

Firms settle with Japan company involved in 1999 nuke accident
MITO, Japan, Feb. 14 (Kyodo) - Firms that saw sales drop in the wake
of a 1999 nuclear accident in Tokaimura, Ibaraki Prefecture, have
reached a 100 million yen settlement with a nuclear processing firm
that caused the disaster, parties to the case said Friday.
The settlement was reached at the Mito District Court in the
prefecture between a fisheries firm in the Ibaraki city of
Hitachinaka and one other company and JCO Co., a uranium processing
subsidiary of Sumitomo Metal Mining Co.
The plaintiffs were asking for 136 million yen in damages.
The settlement is the first of its kind in suits filed over the Sept.
30, 1999 accident in which a nuclear fission chain reaction occurred
at JCO's plant, 120 kilometers northeast of Tokyo, exposing more than
600 people to radiation and resulting in the deaths of two plant
workers.
In the suit, the two companies were asking for compensation worth six
months of sales. JCO has already paid the plaintiffs amounts of money
equal to three months worth of estimated losses following the
accident, or a total of 47 million yen.
Papers filed with the court and other documents show that the
plaintiffs saw sales sharply drop after the accident, partly because
their clients refused to trade with them. Sales at the two companies
for six months through March 2000 fell by 170 million yen compared
with the same period a year earlier.

Japan, Russia to set up nuclear sub disposal task force
MOSCOW, Feb. 13 (Kyodo) - Japanese and Russian officials in charge of
a bilateral program to dismantle decommissioned Russian nuclear
arsenal agreed Thursday to set up a joint task force by April to
promote the dismantling of retired Russian nuclear submarines in the
Russian Far East.
The project, first launched in 1993, has made slow progress. Japan's
Prime Minister Junichiro Koizumi called for stepped-up efforts to
dismantle decommissioned Russian nuclear subs during a visit to
Moscow in January.
Japan and Russia established the nuclear weapons disposal committee
in 1993 after Russia's Pacific Fleet was found to have been disposing
radioactive waste in the Sea of Japan.
At Thursday's meeting, the Japan-Russia nuclear weapons disposal
committee agreed to begin with the dismantling of Victor-III
submarines now abandoned in Russian naval bases and agreed to
intensify work on the project.
The two sides also agreed to set up rules governing the use of funds
that have been appropriated by the Japanese government for the
dismantling operation.
Japan has provided 20 billion yen to finance the dismantling
operation, and 15.8 billion yen remains untouched.
The project has been languishing because of ''slow decision-making
process'' in Russia, a Japanese government source said.
