ANO Unit 2 Sets Refueling Outage Records



RUSSELLVILLE, Ark., Oct. 14 /PRNewswire-FirstCall/ -- Arkansas 

Nuclear One's Unit 2 ended a 20-day refueling outage when it 

reconnected to the electrical grid earlier today. The outage, the 

unit's 16th for refueling, set plant and world records for shortest 

duration and industrial safety. In separate actions, operator Entergy 

Nuclear said it will apply this week to the Nuclear Regulatory 

Commission for renewal of the Unit 2 operating license.



This latest Unit 2 refueling outage was the quickest in ANO history 

with duration of 20 days and 11 hours. The previous best for shortest 

duration was 21 days and 19 hours set by Unit 2 during its previous 

refueling in spring 2002. The 20-day outage is also a world record 

for nuclear reactors designed by Combustion Engineering. The previous 

Combustion Engineering record was also held by ANO's Unit 2.



In addition to replacing about a third of the 177 fuel assemblies in 

the reactor's core and performing multiple maintenance activities, 

the reactor vessel head was also inspected and found to be in good 

shape. All 90 reactor vessel head nozzle penetrations were thoroughly 

inspected and found to be leak-free. Inspections of reactor vessel 

heads for pressurized water reactors have taken on a new significance 

since last year when severe reactor vessel head corrosion was 

discovered at the Davis-Besse nuclear plant in Ohio.



Industrial safety performance was also the best ever for an ANO 

refueling outage. With more than 1,500 people working nearly three 

weeks in a heavy industrial environment, injuries were limited to 

only five first aid cases.



This week Entergy plans to apply with the NRC for renewal of the Unit 

2 operating license. If approved, Unit 2 will be authorized to 

operate until 2038. The unit's current operating license expires in 

2018. The NRC's application review is expected to take about two 

years. The review process involves both environmental and technical 

considerations. ANO's Unit 1 operating license was renewed in 2001. 

Unit 1 is now authorized to operate until 2034.



The nuclear businesses of Entergy Corporation (NYSE: ETR) are 

headquartered in Jackson, Miss. Entergy Nuclear is the second largest 

and fastest growing operator of nuclear power plants in the nation. 

It operates five reactors at four locations in Arkansas, Mississippi 

and Louisiana under regulatory jurisdictions and five reactors at 

four sites in Massachusetts, New York and Vermont. Entergy Nuclear 

also provides management services to the Cooper nuclear station in 

Nebraska and is the nation's largest provider of license renewal and 

decommissioning services to the nuclear power industry.

EU to take Britain to court over nuclear sub waste



BRUSSELS, Belgium (Reuters) - The European Commission said Thursday 

it was taking Britain to court for breaking European Union rules on 

disposing radioactive waste from a dockyard that refits and refuels 

nuclear submarines.  



Under EU law, EU governments must inform the Commission in advance if 

it is planning to grant authorization to dispose of radioactive waste 

so that it can assess the risks to health in neighboring countries.



Britain failed to give the required six months' notice when 

authorizing waste from Devonport dockyards, run by Devonport 

Management Limited, owned by KBR, a division of U.S. engineering and 

construction firm Halliburton, the Commission said.



"Since the disposal of radioactive waste may affect another member 

state from a health point of view, assessment of the radiological 

impact of such waste by the Commission remains crucial," it said in a 

statement announcing it was taking Britain to the European Court of 

Justice.



The EU court can demand changes in government behavior but has no 

power to impose penalties the first time it hears a case.

Russia puts off start-up of Iran nuclear plant



MOSCOW, Oct 13 (Reuters) - Russia on Monday postponed plans to start 

up a nuclear reactor in Iran until 2005 saying the delay was due 

technical reasons and nothing to do with U.S. concerns over its 

nuclear ties with the Islamic Republic.



A source in the Russian Atomic Energy Ministry told Reuters Moscow's 

plans to help Iran build the nuclear plant were still intact despite 

U.S. accusations Tehran was seeking to develop nuclear weapons under 

the cover of a civilian programme.



"We are putting off the start-up of the first reactor of the Bushehr 

plant because much of the technical equipment has not been supplied 

in time," the source said.



"But mind you this has nothing to do with politics and other issues 

surrounding Iran at this point."



The huge plant near the southern port of Bushehr was initially 

supposed to open some time next year.



The announcement was made three days before U.N. nuclear watchdog 

chief Mohamed ElBaradei was due to visit Tehran and two weeks before 

a deadline expires for Iran to present evidence that its nuclear 

programme is entirely peaceful.



Speaking on condition of anonymity, the official said Moscow and 

Tehran still planned to sign a crucial agreement obliging Iran to 

return spent nuclear fuel to Russia. The two sides have been locked 

in months of negotiations on the accord.



Moscow has said it is prepared to drop plans to build the reactor if 

the U.N.'s International Atomic Energy Agency presents evidence of a 

weapons programme.

Canadian PM to try to sell China nuclear reactors



OTTAWA, Oct 14 (Reuters) - Canadian Prime Minister Jean Chretien will 

try to persuade China to buy more Canadian nuclear reactors when he 

visits the country next week, officials said on Monday.  



China has already bought two Candu reactors for a total cost of 

around C$4 billion ($3 billion) and officials said both had been 

completed ahead of schedule.



"Obviously we would like to see more Candus built in China...I'm sure 

the prime minister will be pressing China to look at the experience 

we've had," one official told a news briefing.



"I'm expecting that the process of continuing dialogue and 

cooperation with China will be very much on the table and we'd like 

(this) to lead eventually to building more reactors."



China's nuclear generation capacity was 5,400 megawatts at the end of 

last year, accounting for less than two percent of the country's 

total. That is scheduled to rise to 8,700 megawatts by 2005.



The official said other areas where Canadian exports to China might 

increase included grain and transportation equipment.

Experts fear terrorist N-bomb



International nuclear experts are quietly confronting the most 

terrifying scenario of all -- what to do if terrorists manage to 

build and detonate a nuclear fission bomb, a diplomat and senior 

nuclear scientist said.



The diplomat, who is also close to the International Commission on 

Radiological Protection (ICRP), told reporters a team of ICRP experts 

from around the world had met this weekend in Stockholm to discuss 

emergency responses should this scenario become a reality.



Asked what was the worst-case realistic scenario for an act of 

nuclear terror, the diplomat said: "A very badly done, but done 

nuclear weapon."



After September 11, the Vienna-based International Atomic Energy 

Agency (IAEA) warned states must tighten up security of radioactive 

sources to prevent terrorists getting hold of them to make a "dirty 

bomb" -- when a conventional explosive like dynamite is used to 

disperse radioactive material.



The IAEA has always said the possibility of terrorists making nuclear 

fission devices was very low because of the difficulty of acquiring 

bomb-grade uranium or plutonium and the technical sophistication 

needed to construct a fission bomb.



"The biggest hurdle in making nuclear weapons is getting weapons-

grade material," IAEA spokeswoman Melissa Fleming said.



But the diplomat, who is also a nuclear scientist, suggested that it 

was not so hard: "Do you really believe it's difficult?"



As for the technical difficulties, he said: "I know that to do a bad 

nuclear weapon, not one that would destroy a whole city but just to 

make an explosion, is not so difficult."



Although it would take 25 to 35 kilograms (55 to 80 pounds) of highly 

enriched uranium (HEU) to make a conventional nuclear bomb, the 

diplomat said in Stockholm that it would be possible to make a less 

efficient bomb with "just a few kilos."



"The efficiency of the explosion will be bad (but) you will get a 

chain reaction," he said, adding there would probably be no mushroom 

cloud, the trademark of a sophisticated fission bomb.



In the simplest terms, the chain reaction in a classic atomic bomb is 

triggered when a high explosive like TNT is detonated and compresses 

the highly unstable bomb-grade material into such a dense mass that 

it sparks a fission explosion.



Without giving details, the diplomat said a crude fission device 

could cause significant damage -- in contrast to the kind of dirty 

bomb that has been widely discussed in the media, aimed more at 

causing panic than physical harm and destruction.



In December 1994, Czech police seized 2.72 kg of HEU from the back 

seat of a parked car in Prague, the largest ever seizure of bomb-

grade nuclear material.



Shifting to the topic of dirty bombs, the diplomat said underground 

railway systems could be targets. He said highly radioactive caesium-

137 powder, found in many hospitals, would be the likely material of 

choice.



"When the train is coming it is like a piston. You just open the 

canister and ... after two or three hours you'll have caesium all 

over the tube," the diplomat said.



"Nothing will (probably) happen from the health point of view but 

people will be so afraid that no one will use it," he said. "I know 

the London Underground has a working party looking at this."



Several dirty bomb simulation studies have concluded that an attack 

with caesium would result in diluted, low-level exposure.



But in 1987, a single canister of it was found in a Brazil junkyard 

and caused a serious radiation contamination disaster. A total of 249 

people were exposed, 10 were seriously injured and four died due to 

heavy exposure.



There has never been a dirty bomb attack, but the diplomat said he 

assumed it was only a matter of time before it happened.

Siemens to Develop New Cancer Radiation Method



FRANKFURT (Reuters) - A high-precision radiation therapy for cancer 

that can be used to treat leukemia patients and children will be 

developed commercially for the first time and could reach hospitals 

in three years, a Siemens executive said Friday.  



The technology, for which German industrial conglomerate Siemens 

bought the license this week, precisely targets tumors that were 

previously too dangerous to treat with radiation, the executive of 

the company's medical division said.



"We're talking primarily about chondrosarcomas (tumors of cartilage 

cells), brain-stem, eye and pediatric cancers, leukemia," Medical 

Executive Vice President Hermann Requardt told Reuters by phone.



He said an extra five to 10 percent of cancers would be treatable 

with the new type of radiation.



The technique destroys cancerous cells by shooting so-called "heavy 

ions" at them at extremely high speeds. A particle accelerator fires 

out charged Carbon-12 nuclei which are guided precisely to their 

target by magnetic fields, sparing surrounding tissue and organs.



The technology was developed by German particle physics research 

institute GSI in conjunction with partners including the German 

Cancer Research Center and Heidelberg University and was tested in 

the German city of Darmstadt.



"Since 1997, approximately 200 patients participating in a clinical 

study were successfully treated with this method," GSI and Siemens 

said in a joint statement. "The results exceeded our expectations, 

since we were able to observe a very quick as well as lasting tumor 

reaction in these patients," Juergen Debus of Heidelberg University 

said in the statement.



COST OF TREATMENT



The cost in treatment alone of heavy-ion radiation has been estimated 

as being at least twice that of conventional radiation treatment.



But Requardt said that factoring in potentially shorter treatment 

times and higher success rates -- saving on prophylactic care -- the 

costs could be roughly comparable.



"There will be a strong desire to go for this very patient-friendly 

therapy," he said, adding that it could be carried out on an out-

patient basis.



Siemens still has a few legal and regulatory steps to go through 

before it will start building the machines but Requardt said he did 

not foresee any difficulties.



"We don't see any major hurdles," he said. "The plans are ready and 

after ground-breaking we expect it will take three to four years 

before we can start," he said.



He added that the company already had strong interest from investors 

and might finance the initiative privately with an initial investment 

of up to 100 million euros ($117 million).



Requardt said it would cost around 30 million euros to build each 

machine, and that the first commercially working system would 

probably be in Germany, which has a mixture of public and private 

health care.



The new technology will complement Siemens' existing portfolio of 

medical products which includes X-ray, magnetic imaging and 

monitoring equipment.



"The technology brings a precision of millimeters into the tumour 

treatment and to do that you have to know exactly where the organs 

are," he said. ($1-.8522 Euro)

Homeland Security Research Corporation --HSRC-- Newsletter Examines a 

Forecasted $9 Billion Radiation Detection Portal Industry



SAN JOSE, Calif.--(BUSINESS WIRE)--10/02/2003-- HSRC's Newsletter 

Issue No. 6 Covers: Radiation Detection Portals, Fluoroscopic X-Ray 

Systems, Nano-Technology in Homeland Security, a Review of Canberra 

Inc. and National Laboratories in Homeland Security



Homeland Security Research Corporation (HSRC) announced the 

publication of its newsletter: Homeland Security Research (Issue 6).



The new 25-page newsletter -- dedicated to tracking and analyzing 

significant trends in homeland security -- covers market, technology, 

anti-terror, business and company trends. The lead article reviews 

the nuclear/radiological detection portals industry, and includes a 

detailed analysis of nuclear/radiological detection portals, their 

role in mitigating terrorist threats and the ways the technologies 

and markets should evolve to provide a credible defense.



"The economic disruption and human suffering that will follow a 

terror attack using a radiological 'dirty bomb' would be enormous," 

said Johnathan Tal, HSRC's president and publisher. "Both industry 

and government should and could do much more to reduce our 

vulnerability and increase our detection capabilities. We have just 

published a pair of comprehensive market and product reports on the 

subject of nuclear/radiological detection portals. Our market report 

forecasts a 1,300% growth in funding for nuclear/radiological 

detection portals over the next 7 years: from about 2,500 portals 

today to about 10,000 screening systems by the end of the decade."



Another article in the newsletter examines two new fluoroscopic x-ray 

systems -- a new twist on a century-old technology -- that offers a 

possible solution to expensive and risky manual searches of 

suspicious luggage and parcels.



Nano-technology, a subject that raises the hopes of both security 

planners and vendors, is reviewed in detail.
