Exelon Energy wants to begin sending low-level radioactive waste from its Limerick nuclear plant to the Peach Bottom nuclear plant in York County.

Exelon has applied to the U.S. Nuclear Regulatory Commission to amend its operating license so that each year it can send one or two truckloads of the waste from the Montgomery County plant to Peach Bottom, where it would be stored.

For decades, most low-level radioactive waste generated at nuclear plants in the East has been sent to a licensed low-level radioactive waste facility near Barnwell, S.C.

But in July 2008 the facility stopped accepting waste from all but three states.

The on-site storage facility at Limerick is filling up, but 98 percent of the storage capacity at Peach Bottom is available for use, said Rochelle Benson, an Exelon spokeswoman at Peach Bottom.

From the Brattleboro Reformer:

Two weeks ago, Yankee revealed a test well on site showed elevated levels of tritium in groundwater. The monitoring well showed levels of tritium ranging between 14,000 and 28,100 picocuries.

The source of the tritium has not yet been determined, but it was during the initial investigation that regulators learned there was in fact buried piping in use at the power plant.

Last week, during a search for the source, Yankee engineers discovered more than 200 gallons of contaminated water in a 40-foot-long pipe trench in the plant’s radiation waste building.

The water was found to be contaminated with up to 2 million picocuries per liter of tritium, 13,000 picocuries per liter of cobalt-60 and 2,460 picocuries per liter of zinc-65.

The Environmental Protections Agency’s drinking water limit for cobalt-60 is 100 picocuries per liter and for zinc-65 is 300 picocuries per liter.

From the Burlington Free Press:

At least 20 nuclear power plants around the country have reported tritium soil or water contamination, based on a Free Press examination of Nuclear Regulatory Commission documents and information gleaned from interviews with advocates and critics of nuclear power.

Among the 20 plants are six boiling-water reactors owned by Entergy Nuclear, the Louisiana-based firm that has owned Vermont Yankee since 2002 and is seeking to have Vermont Yankee’s operating license for the 650-megawatt facility in Vernon extended for another 20 years.

From the Hazleton Standard Speaker:

Thyroid cancer rates in Pennsylvania soared in recent decades and radiation from nuclear power plants may be the cause, a study released Thursday said.

Joseph Mangano, who authored the study which appeared in the International Journal of Health Services and is executive director for the Radiation and Public Health Project, called the growth in the number of cases "an epidemic."

Pennsylvania's incidence of thyroid cancer in the mid-1980s was 40 percent below the national rate, and now the rate is 44 percent above the national rate, he said.

"Something occurred to change Pennsylvania's rate from low to high, and one of these possible factors is radiation from reactors," Mangano said.

Some of the highest thyroid cancer rates occur in eastern Pennsylvania, which has the nation's largest concentration of nuclear reactors, including the Susquehanna Steam Electric Station in Salem Township, he said.

  • First Energy, the owner of Three Mile Island Unit 2, has sold the TMI-2 electrical rotor and stator to Siemens Power Group. Siemens has sold them to Progress Energy in North Carolina and has hired Biggie Power Constructors to ship them.
  • The TMI-2 rotor and stator are not contaminated.
  • The rotor and stator will be shipped to North Carolina in two separate shipments. Biggie Power Constructors is the shipper.
  • The first shipment will be the rotor in early February and it will go from TMI by truck to a rail siding about two miles north of the plant near Royalton. From there the rotor will be shipped by rail to North Carolina. This rotor weighs about 170 tons.
  • The stator is scheduled to be shipped sometime in early to mid-March and will travel from TMI to Havre de Grace in Maryland on a large multi-axel transporter. The stator weighs 460 tons and will take five days to reach Havre de Grace. Biggie Power Constructors is working with Penn DOT to secure all the required permits. The stator shipment to Havre de Grace will involve crossing the Rt. 30 bridge and Interstate 95.
  • Exelon Nuclear is making notifications to local stakeholders as part of our outreach program. For more information about the shipments you can contact the following point of contact at Biggie Power Constructors:

From the Patriot News:

Five years ago, Chapter 14 went into effect making it easier for companies to shut off customers’ utilities when they get behind in payments, scuttling protections that had been in place through the Public Utility Commission.

Reports from the PUC show that shutoffs have increased dramatically since the law was passed, and that has meant families making dangerous decisions on how to heat their homes.

The Legislature erred five years ago and should make changes to the law to give the PUC — not private companies — once again more flexibility as the final arbiter on consumers’ utility shutoffs and reconnections.

From the DEP:

The Department of Environmental Protection said today that officials in Economy, Beaver County, located the nuclear density gauge that was reported missing last week by Coraopolis-based Jeff Zell Consultants Inc.

A member of Economy’s road crew discovered the device intact and in its transportation case along Cooney Hollow Road and immediately reported it to police.

From Beyond Nuclear:

Background: Despite assuring the State of Vermont for more than a year that it had no buried pipes carrying radioactivity, Entergy Nuclear’s Vermont Yankee reactor has revealed it is leaking radioactive tritium, almost certainly from underground pipes that it now admits do exist. In fact, Vermont Yankee has even announced the discovery of “highly radioactive water,” 50 times more radioactive than would be allowed in drinking water by the U.S. Environmental Protection Agency. Nuclear expert Arnie Gundersen has made clear that Entergy Nuclear Vermont Yankee has indeed lied about the existence of buried pipes over the course of many months.

Our View: Entergy Nuclear has betrayed the trust of the lawmakers, regulators, and citizens of Vermont. Simultaneous with its revelation of radioactivity leaks on site, Vermont Yankee spokespeople engaged in a predictable campaign to downplay the health and safety risks of tritium. However, tritium can impact the human body right down to the DNA level, and can cross the placenta from mother to fragile fetus. At such intimate levels, tritium can and does damage human health, leading to cancer, genetic damage, birth defects, and other maladies. The National Academy of Science has reported consistently over the decades that any exposure to radioactivity, no matter how low the dose, still carries a health risk. As reactors age – and Vermont Yankee is nearly 40 years old – its systems, structures and components degrade, worsening tritium leaks from buried piping. Vermont Yankee’s license should not be extended 20 additional years.

What You Can Do: If you live outside Vermont, contact Vermont’s Governor, Jim Douglas, and let him know that the safety, security, health and environmental risks of Vermont Yankee could carry with them radioactive stigma effects, impacting Vermont’s tourism industry and agricultural products. If you live inside Vermont, contact your legislators and urge that they vote against the 20 year license extension at Vermont Yankee when the issue comes up for legislative action in the next few months.
