Capacity at Japanese nuclear reactors drops to 73% in FY 2002



TOKYO, April 4 (Kyodo) - Fifty-two nuclear reactors used commercially 

in Japan ran at 73.4% capacity in fiscal 2002, slipping below the 80% 

level for the first time in eight years, the Nuclear and Industrial 

Safety Agency said Friday.



Agency officials attributed the decline mainly to suspended 

operations at a number of reactors for safety checkups following a 

cover-up scandal involving Tokyo Electric Power Co. (TEPCO) last 

summer and suspension of operations at other reactors due to front-

loaded or extended regular checkups.



The capacity ratio in fiscal 2002 through March 31 was the lowest in 

the last 10 years, down 7.1 percentage points from 80.5% in the 

previous fiscal year, they said.



The capacity ratio stayed at the 80% level from fiscal 1995 to fiscal 

2001, with the highest rate of 84.2% in fiscal 1998.



By reactor type, the capacity ratio was 61.9% at 29 boiling-water 

reactors, down 16.7 points from fiscal 2001 due to the TEPCO scandal.



The ratio at 23 pressurized-water reactors marked a record 89.1%.



Meanwhile, the agency said it received 14 reports of accidents in 

fiscal 2002, compared with 16 in the previous fiscal year.



However, the data does not include a number of defects such as 

fractures at many reactors.

Rocky Flats Workers Exposed to Radioactive Material



GOLDEN, Colo. (AP) - For the second time in a week, an accident 

exposed workers to minor levels of radioactive material at the Rocky 

Flats former nuclear weapons plant.



Eight such accidents were reported at the plant in all of last year.



A contractor, Kaiser-Hill, is being paid $7 billion to clean up the 

site and could receive a bonus if it completes the job before the end 

of 2006.



``They're anxious to close Rocky Flats, so we ask, `Are they being 

hasty? Are they being sloppy?''' said Steve Gunderson, the state 

health department's official in charge of monitoring Rocky Flats.



However, he said he had concluded that the two accidents were 

unrelated and didn't indicate a pattern of problems.



Kaiser-Hill is investigating the incidents and ``will make any 

appropriate changes if any are deemed necessary,'' company spokesman 

John Corsi said.



In the latest accident, a filter fell off an exhaust fan system 

Monday, releasing accumulated contamination. Two of the six workers 

in the affected room at the time tested positive for possible minor 

contamination and will be tested further, Department of Energy 

spokesman Pat Etchart said.



The exposure appeared to be well below federal limits, Gunderson 

said.



Five days earlier, workers were installing a filter system in a 

separate building when air from a contaminated room backed into the 

rest of the building. Three of the 33 workers involved showed minimal 

exposure and were undergoing further testing.



No radioactive material escaped from the buildings, Etchart said.

Lawsuit Filed to Block Radioactive Trash



YAKIMA, Wash. (AP) - Activists sued the Energy Department on 

Wednesday to keep it from shipping radioactive trash through Oregon 

to Washington state.



The federal lawsuit alleges that plutonium-contaminated shipments 

headed to the Hanford nuclear site could be terrorist targets and put 

Oregon residents at risk.



``These shipments are like deadly `dirty bombs' of plutonium waste 

being trucked through our communities,'' said Gerald Pollet of Heart 

of America Northwest, a Seattle-based Hanford watchdog group that 

filed the suit with Columbia Riverkeeper, the Sierra Club and the 

Washington Physicians for Social Responsibility.



Energy Department spokeswoman Colleen Clark had no comment on the 

suit, which agency officials had not seen Wednesday. But she said the 

shipments are subject not only to federal inspection but also to 

monitoring by the states through which the waste is transported.



``The material is transported in casks certified by the Nuclear 

Regulatory Commission, specific to the material that we are 

transporting,'' Clark said. ``They're all very, very robust.''



The suit follows one filed last month by the state of Washington 

after the department refused to guarantee that the 78,000 barrels of 

radioactive trash already at Hanford would be shipped to a dump in 

New Mexico.



The department has suspended shipments from California and Ohio to 

Hanford at least until an April 18 federal court hearing on the 

state's lawsuit.

Japanese Gov't to end survey on depleted uranium bullets in Okinawa



NAHA, Japan, April 3 (Kyodo) - The science and technology ministry 

has informed the Okinawa prefectural government that it will end its 

environmental survey on depleted uranium-tipped bullets fired by U.S. 

military jets in the waters around a tiny Okinawa island between 1995 

and 1996, local government officials said Thursday.



The Education, Culture, Sports, Science and Technology Ministry has 

told the local government that it can find no negative effects from 

the uranium after surveying the area around the uninhabited Torishima 

Island.



The ministry has handed over a report on the results of the survey 

which started in 1997 and said it intends to end the survey as there 

are no ill effects on waters, soil or air.



The ministry said it is considering implementing a standard 

environmental radioactivity survey conducted nationwide around the 

site in the future, according to the officials.



However, the prefectural government and the government of Kumejimacho 

town which governs the island are requesting the central government 

continue the survey and also conduct medical checks on residents of 

the town.



In December 1995 and January 1996, U.S. Marine AV-8B Harrier jets 

fired 1,520 depleted uranium-tipped bullets during exercises at the 

uninhabited coral island, about 100 kilometers west of the main 

Okinawa Island.



The agency earlier said high-density uranium was found in soil 

samples collected in one of 69 sites around Torishima Island.



About 340 micrograms of high-density uranium per gram of soil was 

detected in samples taken from a slope into which the bullets had 

been fired on the northern part of the island. This amount is nearly 

200 times higher than the amount found in soil samples collected from 

other parts of the island.



The research team otherwise found no evidence of any detrimental 

effects on the island following a study of soil, water and fish 

samples taken from various locations around Torishima Island, an 

earlier report said.



The report said that ''the effect of the depleted uranium is 

considered negligible, because the island is uninhabited.''

Simpler Method of Animal Cloning Using Nuclear Transfer is Focus of 

Two Papers in Cloning and Stem Cells



LARCHMONT, N.Y.--(BUSINESS WIRE)--April 3, 2003--Two variations of a 

new, user-friendly method of cloning an adult animal from a single 

cell using the nuclear transfer technique will make animal cloning 

much easier and more cost-effective, according to reports in the 

Spring 2003 (Volume 5 Number 1) issue of Cloning and Stem Cells, a 

peer-reviewed journal published by Mary Ann Liebert, Inc. The two 

papers are available free online at www.liebertpub.com/clo.



The demand for cloned animal embryos is rapidly growing. They have 

become an increasingly valuable resource for commercial agriculture 

and basic science research and are an important source of stem cells, 

which may be useful for treating a variety of medical conditions. 

Simpler and more efficient methods of cloned embryo production are 

needed to meet this rising demand. The "zona-free" cloning method 

described in this issue of Cloning and Stem Cells represents a 

significant advance that will enable scientists to produce cloned 

embryos in nearly half the time, using simpler equipment and 

requiring less operator skill and experience. This simpler technique 

yields live offspring with the same efficiency as previous methods.



"This research will come to be seen as an important milestone in 

somatic cell nuclear transfer and will have remarkable impact on 

further research," says Ian Wilmut, Ph.D., Editor-In-Chief of the 

journal and joint head of the Department of Gene Expression and 

Development at the Roslin Institute. "It is easier to learn these new 

methods. A person with no previous experience of micromanipulation 

can learn the basic routines in 3 weeks."



The two papers describing zona-free nuclear transfer originate from 

the laboratories of Teija Peura and co-workers from the South 

Australian Research and Development Institute, and Bjorn Oback, and 

colleagues at New Zealand-based AgResearch Ltd, the University of 

Waikato, and the University of Groningen (The Netherlands).



Animal cloning by nuclear transfer involves removing the nucleus from 

an adult animal cell and transferring it into an egg cell that has 

had its nucleus removed. The egg containing the donated nucleus is 

then stimulated to divide and form an embryo, and the embryo is 

transplanted into a female animal, where it continues to develop, 

resulting in the birth of cloned offspring.



Until now, nuclear transfer has relied on highly technical and 

precise methods involving micromanipulation to remove and inject the 

nuclei. The Oback paper describes a zona-free protocol used in 

cattle, in which the zona pellucida--a thick, transparent membrane 

that surrounds the egg--is removed, and the egg is split into two, 

allowing for easy removal of the nucleus. The contents of one or more 

enucleated eggs are then placed in a fusion chamber together with the 

donor nucleus from an adult animal and are fused via electrical 

stimulation. Peura's "reverse-order" zona-free cloning method 

involves removing the nuclei from zona-free sheep oocytes after the 

egg has already been fused with an adult donor cells. Both techniques 

proved to be efficient methods for producing cloned embryos and 

viable offspring.



Cloning and Stem Cells is an authoritative peer-reviewed journal, 

published quarterly in print and online, that focuses on 

understanding developmental plasticity and defining the molecular 

mechanisms that regulate differentiation or dedifferentiation of 

nuclei and cells. A table of contents and free sample issue may be

Progress Energy Named a Finalist for Edison Electric Institute's 

Prestigious 'Edison Award'



WASHINGTON, April 4 /PRNewswire-FirstCall/ -- Leadership in corporate 

ethics, excellence in nuclear operations and a pioneering air 

emissions partnership with state leaders have garnered Raleigh-based 

Progress Energy a finalist berth for the electric power sector's 

highest honor, the Edison Award.



(Photo: http://www.newscom.com/cgi-bin/prnh/20020923/CHM008LOGO-c )  



The prestigious prize is given annually by the Edison Electric 

Institute (EEI) to the U.S. shareholder-owned member and 

international member making the most outstanding contributions to the 

advancement of the industry. A committee of national industry trade 

publication editors and a panel of past and current EEI chairmen 

select the finalists and ultimate winners. This year's award, the 

44th, will be announced June 4 at EEI's annual convention in 

Honolulu, Hawaii. "These companies are emblematic of the ingenuity 

and vision that are the hallmarks of our industry," said EEI 

President Thomas R. Kuhn in announcing the selection of the 

finalists. "Their leadership and boldness, and their ability to see 

what lies ahead in a constantly changing industry, are what set them 

apart."



In 2002, Progress Energy distinguished itself with high standards in 

ethics and corporate governance, and the company was one of just 

three companies in a survey of 500 that received the highest possible 

rating by Standard & Poor's for corporate transparency and behavior. 

Progress also was ranked in the top ten out of 1,245 companies for 

board of director independence by S&P.



Excellence in nuclear power operations was also a factor in Progress' 

nomination, EEI said, pointing to a new world record set by the 

company's Brunswick Nuclear Plant for a breaker-to-breaker run of a 

boiling-water light reactor lasting more than 707 days. In October, 

the company's Robinson Nuclear Plant in Hartsville, S.C., amassed a 

517-day run, a new company record for a pressurized-water reactor. 

These individual accomplishments were part of an overall Progress 

Energy nuclear fleet that in 2002 achieved a combined capacity factor 

of 97.3 percent, its best ever.



Finally, Progress distinguished itself for its collaboration in a 

diverse stakeholder group that in 2002 crafted a state law that will 

significantly reduce emissions of sulfur dioxide and nitrogen oxides 

from coal-fueled power plants, while keeping electric rates stable 

and maintaining the importance of coal-based generation in the 

state's fuel portfolio.



Through its work in this collaborative process-which involved 

environmental groups, state regulators and other groups-Progress 

demonstrated that environmental progress can go hand in hand with 

fuel diversity and a commitment to the future of coal-based electric 

generation.
