Despite billions spent on cleanup, Hanford won't be clean for thousands of years [09Fe... - 0 views

  • Some radioactive contaminants at the Hanford Nuclear Reservation will threaten the Columbia River for thousands of years, a new analysis projects, despite the multibillion-dollar cleanup efforts by the federal government.
  • The U.S. Department of Energy projections come from a new analysis of how best to clean up leaking storage tanks and manage waste at Hanford, a former nuclear weapons production site on 586 square miles next to the Columbia in southeastern Washington.
  • Oregon officials say the results, including contamination projections for the next 10,000 years, indicate the federal government needs to clean up more of the waste that has already leaked and spilled at Hanford instead of capping and leaving it, a less-expensive alternative.

  • "We think it should force a re-look at the long-term cleanup plan at Hanford," said Ken Niles, assistant director of the Oregon Department of Energy. "We don't want that level of contamination reaching the Columbia River."
  • The U.S. Department of Energy report says the risks from some high-volume radioactive elements, including tritium, strontium and cesium, have already peaked and should diminish relatively quickly. For all locations at Hanford, the peak radiological risk has already occurred, the report says.
  • Much of Hanford's radioactivity comes from strontium-90 and cesium-137, which have half-lives of roughly three decades, the GAO said, meaning much of the risk should fall relatively quickly.
  • Hanford produced nuclear materials from 1944 through 1988, operated nine nuclear reactors to produce plutonium and generated millions of gallons of radioactive and hazardous waste. Some of the waste was dumped directly into ditches, some was buried in drums and some was stored in 177 huge underground tanks, including 149 leak-prone single-walled tanks.
  • It's now the nation's most contaminated radioactive cleanup site.
  • A U.S. Government Accountability Office report in September on tank cleanup said the total estimated cost has risen dramatically and could go as high as $100 billion, well above the current $77 billion estimate. The latest deadline for completing cleanup is 2047, though cleanup dates have been steadily pushed back.
  • But Mary Beth Burandt, an Energy Department manager, said the agency is undecided and will likely propose steps to address public concerns. Such steps could include more treatment, barrier walls to block contaminant flows and limits on long-lived radioactive elements in incoming waste.
  • Health risks from Hanford's contamination are long-term, not immediate. They're expressed in terms of cancer cases after a lifetime of drinking well water from the site, with a one in 10,000 risk considered high. But many of the contaminant levels at the site exceed health benchmarks by wide margins.

Canada News: B.C. braces for wave of debris from Japanese tsunami [25Dec11] - 0 views

  • The B.C. government says it will begin working with national and municipal officials this January to prepare for the massive wave of debris heading to Pacific Northwest shores because of the March 11 earthquake and tsunami in Japan.
  • Julianne McCaffrey, a spokeswoman for the Emergency Management B.C., part of the Ministry of Public Safety and Solicitor General, has confirmed the government is creating a Provincial Tsunami Debris Working Group. She said the arrival of the debris, which some experts have argued covers an area the size of California, has raised some “complex jurisdictional issues,” which the working group will clarify, so officials hope to identify key members by Jan. 6
  • Curtis Ebbesmeyer, an oceanographer from Seattle, Wash., said he has confirmed that as many as six fishing buoys have washed ashore between mid-Oregon and Alaska and are tied to the Japanese tsuna

  • Schmunk said a town like Tofino is not equipped to deal with such a massive influx of flotsam, noting it doesn’t have enough staff nor enough space in the local landfill.

Seals, walruses… now "unprecedented" number of sea turtle deaths in Vancouver... - 0 views

  • Japanese Tsunami Flotsam Appearing In Kodiak Waters, KMXT by Jennifer Canfield, December 26, 2011:
  • Dr. Curtis Ebbesmeyer [...] says debris will continue to wash up on shores from Kodiak to Oregon for the next few years [...] Ebbesmeyer says scientists are already hypothesizing about the effects of mass amounts of debris traveling through the Pacific Ocean’s currents. He points to an unprecedented number of sea turtles washing up on Vancouver Island. Ebbesmeyer says people who find debris should be especially careful and respectful. Personal items and artifacts can still be reunited with people in Japan. He also suggests testing items for radiation, just to be prudent.  [...]

DOE Releases Draft EIS on Proposed Low-Level Nuclear Waste Sites, Disposal Methods [21F... - 0 views

  • The Department of Energy on Friday issued a draft environmental impact statement (EIS) on low-level radioactive waste disposal, with public meetings set for April and May in cities near potential waste sites in Oregon, Idaho, Washington, Nevada, New Mexico and South Carolina. The EIS addresses greater-than-class-C (GTCC) low-level-radioactive waste (LLRW) as DOE considers new and existing storage facilities. GTCC waste comes from power plants, medical treatments, medical diagnostics and oil and gas exploration, as well as other industrial processes. The EIS and waste sites do not involve high-level waste like spent fuel.
  • In a release, DOE estimates current GTCC and GTCC-like LLRW in storage at 1,100 cubic meters. The EIS estimates an additional 175 cubic meters of waste will be generated each year over the next six decades. In looking for places to store that waste, the EIS analyzes the potential environmental impacts of using both new and existing waste facilities. Disposal methods evaluated include deep geological repository, intermediate depth boreholes, enhanced near-surface trenches and above-grade vaults
  • “disposal locations analyzed include the Hanford Site in Washington; Idaho National Laboratory in Idaho; the Los Alamos National Laboratory, the Waste Isolation Pilot Project (WIPP) and the WIPP vicinity in New Mexico; the Nevada National Security Site (formerly the Nevada Test Site) in Nevada; and the Savannah River Site in South Carolina. The Draft EIS also evaluates generic commercial disposal sites in four regions of the U.S., as well as a no action alternative.”

  • DOE has not yet identified a preferred alternative for waste disposal, but a preferred alternative or combination of alternatives will be identified in the final EIS. Before making a final decision on disposal method or location, the agency would need to submit its findings to Congress and wait for legislative action.

Columbia River Area To Be Contaminated With Nuclear Waste for Millennia [10Feb10] - 0 views

  • given the fact that a new study reports that the Columbia River will be contaminated with nuclear waste from a nuclear weapons plant for thousands—yes, thousands—of years. Even though the government has already spent billions of dollars on cleanup.
  • The Oregonian reports that the Hanford Nuclear Reservation, formerly a nuclear weapons production site, sits on 586 square miles of land next to the Columbia. And it has already leaked and spilled some waste into the river, contaminating the water and surrounding environment with such fun things as strontium, cesium, tritium, and plutonium. The federal government did an analysis of the damage to determine if capping and sealing off the waste would stop more of it from getting out, and also, if more waste could be imported to the site to be buried along with the original waste.
  • The analysis also shows that the U.S. energy department's plan to import low-level and midlevel radioactive waste from other sites to Hanford after 2022 poses "completely unacceptable" risks, [assistant director of the Oregon Department of Energy Ken] Niles said. Washington is also raising concerns about importing more waste. […] Health risks from Hanford's contamination are long-term, not immediate. They're expressed in terms of cancer cases after a lifetime of drinking well water from the site, with a one in 10,000 risk considered high. But many of the contaminant levels at the site exceed health benchmarks by wide margins.

Obama to step up power line projects [07Oct11] - 0 views

  • The Obama administration moved Wednesday to speed up permitting and construction of seven proposed electric transmission lines in 12 states, saying the projects would create thousands of jobs and help modernize the nation's power grid.The projects are intended to serve as pilot demonstrations of streamlined federal permitting and improved cooperation among federal, state and tribal governments. The projects will provide more than 2,500 miles of new transmission lines in Arizona, Colorado, Idaho, New Mexico, Nevada, Oregon, Utah, Wyoming, New Jersey, Pennsylvania, Minnesota and Wisconsin.
  • In all, the projects are expected to create more than 10,000 direct and indirect jobs, help avoid blackouts, restore power more quickly when outages occur and reduce the need for new power plants, officials said."To compete in the global economy, we need a modern electricity grid," Energy Secretary Steven Chu said Wednesday in a statement. "An upgraded electricity grid will give consumers choices while promoting energy savings, increasing energy efficiency and fostering the growth of renewable energy resources."

Mini-Nukes Back From Grave As Fluor Invests In NuScale Power [16Oct11] - 0 views

  • NuScale Power–one of the pioneers in small, modular nuclear reactors—is back from the dead, thanks to a $30 million infusion from global construction giant Fluor.
  • Under the terms of the deal, Fluor will invest $30 million into Corvallis, Oregon-based NuScale, as well as help the company navigate the arduous and technically complex approval and licensing process. Fluor will also cooperate with NuScale on procurement, logistics and construction when it comes time to build its power plants.
  • NuScale suspended operations in January amid a cash crunch. Modular nuclear reactors take uranium, or in some cases thorium, and produce steam for turbines via heat generated in fission reactions. That is pretty much how large nuclear power plants operate. The difference comes in manufacturing and construction.
