Measuring Radiation in Japan

IWAKI, Japan — Kiyoko Okoshi had a simple goal when she spent about $625 for a dosimeter: she missed her daughter and grandsons and wanted them to come home. 

Local officials kept telling her that their remote village was safe, even though it was less than 20 miles from the crippled Fukushima Daiichi nuclear power plant. But her daughter remained dubious, especially since no one from the government had taken radiation readings near their home.

So starting in April, Mrs. Okoshi began using her dosimeter to check nearby forest roads and rice paddies. What she found was startling. Near one sewage ditch, the meter beeped wildly, and the screen read 67 microsieverts per hour, a potentially harmful level. Mrs. Okoshi and a cousin who lives nearby worked up the courage to confront elected officials, who did not respond, confirming their worry that the government was not doing its job.

With her simple yet bold act, Mrs. Okoshi joined the small but growing number of Japanese who have decided to step in as the government fumbles its reaction to the widespread contamination, which leaders acknowledge is much worse than originally announced. Some mothers as far away as Tokyo, 150 miles to the south of the plant, have begun testing for radioactive materials. And when radiation specialists recently offered a seminar in Tokyo on using dosimeters, more than 250 people showed up, forcing organizers to turn some people away.

NJ Nuke leaking radioactive water

Tainted nuke plant water reaches major NJ aquifer

LACEY TOWNSHIP, N.J. — Radioactive water that leaked from the nation's oldest nuclear power plant has now reached a major underground aquifer that supplies drinking water to much of southern New Jersey, the state's environmental chief said Friday.

The state Department of Environmental Protection has ordered the Oyster Creek Nuclear Generating Station to halt the spread of contaminated water underground, even as it said there was no imminent threat to drinking water supplies.

The department launched a new investigation Friday into the April 2009 spill and said the actions of plant owner Exelon Corp. have not been sufficient to contain water contaminated with tritium.

Tritium is found naturally in tiny amounts and is a product of nuclear fission. It has been linked to cancer if ingested, inhaled or absorbed through the skin in large amounts.

"There is a problem here," said environmental Commissioner Bob Martin. "I am worried about the continuing spread of the tritium into the groundwater and its gradual moving toward wells in the area. This is not something that can wait. That would be unacceptable."

The tritium leaked from underground pipes at the plant on April 9, 2009, and has been slowly spreading underground at 1 to 3 feet a day. At the current rate, it would be 14 or 15 years before the tainted water reaches the nearest private or commercial drinking water wells about two miles away.

But the mere fact that the radioactive water — at concentrations 50 times higher than those allowed by law — has reached southern New Jersey's main source of drinking water calls for urgent action, Martin said.

He ordered the Chicago-based company to install new monitoring wells to better measure the extent of the contamination, and to come up with a plan to keep it from ever reaching a well.

The contamination is not a new issue, plant spokesman David Benson said, questioning the need for Martin's order.

"We have monitoring wells on site, and the tritium concentration is down steadily, sometimes by as much as 90 percent," he said. "We are drilling more wells, and we will work closely with the state. We have been all along."

Should the plant fail to stem the spread of the contaminated water, the state will do it and bill the company for three times the cost as a penalty, the environmental department said.

Department spokesman Lawrence Ragonese said there are several potential ways to address the contamination, including pumping tainted water out of the ground, or injecting a different part of the aquifer with water to force the plume of contaminated water backward and away from wells.

No option has yet been decided upon.

The radioactive water leaks were found just days after the plant got a new 20-year license in 2009 that environmentalists had bitterly fought for four years. Those problems followed corrosion that left the reactor's crucial safety liner rusted and thinned.

The Nuclear Regulatory Commission and Exelon insist Oyster Creek can operate safely until it is 60 years old. But environmental groups disagree.

"The bad news is Exelon's Oyster Creek plant ... has now become a major threat to South Jersey's drinking water," said David Pringle of the New Jersey Environmental Federation. "The good news is NJDEP Commissioner Martin is taking aggressive action to safeguard our water and hold Exelon accountable for this leaky 40 year old plant."

Julia LaMense of the Eastern Environmental Law Clinic hailed the state's action and condemned the NRC "for letting it come to this."

"It's a sad day when the 'wait and see' approach taken in response to yet another 'trust us' from Exelon results in exactly what we feared — contamination of one of the most significant aquifers in the region," she said.

Oyster Creek went online Dec. 1, 1969, the same day as the Nine Mile Point Nuclear Generating Station near Oswego, N.Y. But Oyster Creek's original license was granted first, technically making it the oldest of the nation's 104 commercial nuclear reactors that are still operating.

Located about 60 miles east of Philadelphia and 75 miles south of New York City, Oyster Creek generates 636 megawatts of electricity, enough to power 600,000 homes a year, and provides 9 percent of New Jersey's electricity.

Nuclear Power vs. Wind

The chart says it all... 

Nuclear Company goes Solar

The French nuclear firm, Areva has purchased, Ausra, the American concentrated solar company. 

Anil Srivastava, head of renewables at Areva, said: "By acquiring Ausra, Areva has taken a major step forward to achieve its strategic ambition in renewables. The Group intends to become the world leader in concentrated solar power (CSP) thanks to a reliable, cost-effective product."

When even nuclear companies think solar is the next big thing, one has to wonder why we feel the need to invest an additional $36B from our federal budget for subsidies for the nuclear industry. 

20GW of French Nuclear Power - out of service

France is being forced to import electricity from Britain to cope with a summer heatwave that has helped to put a third of its nuclear power stations out of action.

With temperatures across much of France surging above 30C this week, EDF’s reactors are generating the lowest level of electricity in six years, forcing the state-owned utility to turn to Britain for additional capacity.

Fourteen of France’s 19 nuclear power stations are located inland and use river water rather than seawater for cooling. When water temperatures rise, EDF is forced to shut down the reactors to prevent their casings from exceeding 50C.

One power industry insider said yesterday that about 20GW (gigawatts) of France’s total nuclear generating capacity of 63GW was out of service.
