In the context of disposal of radioactive waste, a performance assessment is a quantitative evaluation of potential releases of radioactivity from a disposal facility into the environment, and assessment of the resultant radiological doses. The term performance assessment can refer to the process, model, or collection of models used to estimate future doses to human receptors. Typically, a performance assessment is conducted to demonstrate whether a disposal facility has met its performance objectives. In general, a performance assessment considers the following factors:
* Selected scenario (specific features and processes at the disposal facility and in the surrounding area, such as the location of the potential release, location and general characteristics of the receptors, and applicable transport pathways through which radionuclides might reach the environment and pose a threat to the selected receptor groups)
* Performance of the cask or other engineered barrier system used to store low-level waste, limit the influx of water, and reduce the release of radionuclides
* Release and migration of radionuclides through the engineered barrier system and geosphere (those deep-underground portions of the disposal facility where human contact is generally not assumed to occur)
* Radiological dose(s) to the selected receptor group(s)
On December 30, 2008, AREVA Enrichment Services, LLC (a subsidiary of AREVA NC, Inc.), submitted an application to the U.S. Nuclear Regulatory Commission (NRC), seeking a license to construct and operate a gas centrifuge uranium enrichment facility in the United States. Specifically, AREVA has selected a site in Bonneville County, Idaho, for its new facility, which will be known as the Eagle Rock Enrichment Facility.

"In the midst of initiating a federal spending freeze, it is shocking that President Obama's FY 2011 Budget Request released this week pours billions of dollars into two unnecessary nuclear weapons construction projects. There is no demonstrated requirement for either the Uranium Processing Facility (UPF) at the Y-12 National Security Complex nor the Chemical and Metallurgical Research Replacement Nuclear Facility (CMRR-NF) at the Los Alamos National Laboratory (LANL).
"Contrary to the spin, neither of these facilities are needed to ensure the safety, security and effectiveness of our weapons," says Peter Stockton, POGO Senior Investigator.
In addition, DOE does not even have an estimated cost for completing the projects, as the budget describes their total costs as "TBD." "To Be a Disaster," is what POGO fears that term means, based on DOE's atrocious record of soaring construction costs and overruns. For example, the cost of the Highly Enriched Uranium Manufacturing Facility (HEUMF) at Y-12 ballooned from $97 million to $549 million. "
"The Nuclear Regulatory Commission has enlisted the National Academy of Sciences to conduct a study of cancer rates in areas surrounding nuclear facilities across the country, including Beaver County.
The study, which is expected to begin this summer and take up to three years, will examine cancer occurrence and mortality rates in residential populations living near nuclear facilities.
Shippingport was the site of the nation's first commercial nuclear power plant, which was replaced by the Beaver Valley Nuclear Power Station owned by Akron, Ohio-based FirstEnergy Corp.
A previous study released in 1990 found no increased risk of cancer death for people living near nuclear facilities. The study conducted by the National Cancer Institute looked at 107 counties near 62 nuclear facilities, including Beaver County. "
"A drum of highly enriched uranium ended up at the right place, but it got there the wrong way, according to a report confirmed by a spokeswoman at the Y-12 nuclear weapons plant. The incident, which involved a violation of technical safety requirements, took place in mid-March during the first phase of loading uranium into the new $549 million Highly Enriched Uranium Materials Facility. It apparently occurred just a few days before Energy Secretary Steven Chu and other dignitaries arrived to dedicate the new storage facility for bomb-grade uranium.
Ellen Boatner, a plant spokeswoman, said workers "inadvertently" shipped a container that was not certified to be on board the SST-E truck -- a high-security vehicle that was being used to transfer the special nuclear materials from the plant's old warehouse to the new storage facility. Boatner said there were plans for the drum of HEU to be transferred to the facility but not aboard the SST-E."
The Barack Obama administration claims that construction of a second Iranian uranium enrichment facility at Qom began before Tehran's decision to withdraw from a previous agreement to inform the International Atomic Energy Agency (IAEA) in advance of such construction. But the November 2007 U.S. intelligence estimate on Iran's nuclear program tells a different story.
The Iranian decision to withdraw from the earlier agreement with the IAEA was prompted, moreover, by the campaign of threats to Iran's nuclear facilities mounted by the George W. Bush administration in early 2007, as a reconstruction of the sequence of events shows.

"The Nuclear Regulatory Commission has authorized startup of a $3 billion uranium enrichment plant in New Mexico, the first major nuclear facility to be licensed in the US in the past three decades.
NRC officials said in a news release Thursday they are satisfied the facility can begin operations.
The Louisiana Energy Services facility near Eunice will use an enrichment process that employs centrifuges to separate uranium isotopes. The enriched uranium will supply fuel for nuclear power plants in the US and overseas.
LES president and chief executive Gregory Smith calls the NRC approval "a turning point" for the nation's nuclear industry.
The technology used at the New Mexico plant has been in place in Europe for more than 30 years."
"Notice of Intent To Prepare an Environmental Impact Statement for the Proposed International Isotopes Uranium Processing Facility AGENCY: Nuclear Regulatory Commission. ACTION: Notice of Intent. ----------------------------------------------------------------------- SUMMARY: International Isotopes Fluorine Products, Inc. (IIFP), a wholly owned subsidiary of International Isotopes, Inc. (INIS), submitted a license application, which included an Environmental Report (ER) on December 30, 2009, that proposes the construction, operation, and decommissioning of a fluorine extraction and depleted uranium de- conversion facility to be located near Hobbs in Lea County, New Mexico. The U.S. Nuclear Regulatory Commission (NRC), in accordance with the National Environmental Policy Act (NEPA) and its regulations in 10 Code of Federal Regulations Part 51, announces its intent to prepare an Environmental Impact Statement (EIS) evaluating this proposed action. The EIS will examine the potential environmental impacts of the proposed INIS facility. DATES: NRC invites public comments on the appropriate scope of issues to be considered in the EIS. The public scoping process required by NEPA begins with publication of this Notice of Intent. Written comments submitted by mail should be postmarked by no later than August 30, 2010 to ensure consideration. Comments mailed after that date will be considered to the extent practical. "
Parsons has been awarded a two-year contract by LES to "provide engineering, construction management, and construction services" for the expansion phase of the National Enrichment Facility, Parsons announced February 3. The value of the contract was not disclosed. Parsons, a California-based engineering and construction firm, said it was awarded the contract "based on its approach, engineering excellence, and ability to partner and develop the project in a fast-track manner while meeting [NRC] licensing requirements." LES announced in November that it plans to expand the annual capacity of its centrifuge uranium enrichment facility under construction in Eunice, New Mexico from 3 million SWU to 5.9 million SWU. That will push the plant's predicted completion date to the end of 2014, resulting in a total construction cost of more than $3 billion, LES said last year. When completed, the facility will be able to provide 50% of all enriched fuel for the 104 operating power reactors in the US, Parsons said.
The second construction in the plutonium disposition complex at SRS broke ground Friday and was proclaimed "the cornerstone ... of a new nuclear age."
Project workers and dignitaries spoke before the first shovels of dirt were turned over on the $345 million facility.
Ken Chacey, director of site engineering and construction management for the National Nuclear Security Administration, said the event was "a huge event for America" as a move toward energy independence.
The Mixed Oxide Fuel Fabrication Facility (MOX) will turn weapons-grade plutonium into fuel assemblies in use in commercial nuclear reactors. The new facility is the Waste Solidification Building (WSB), which will process low-level and transuranic liquid waste streams from MOX and pit disassembly operations.
Since its groundbreaking in August 2006, Louisiana Energy Services' uranium enrichment facility near Eunice, N.M., has sprung out of the earth and expectations are the $1.5 billion facility will come on line by late 2009.
Dana Starr, communications specialist for the National Enrichment Facility, as it is called, gave a presentation to Midland Rotary Club members Thursday at Midland Center. The plant will produce enriched uranium, which is needed to make fuel pellets that will be sent off to make electricity.
Jordan and the United States have signed a contract for the construction of a modern central storage facility (CSF) for radioactive waste at the Jordan Atomic Energy Commission ((JAEC) in Amman.
JAEC Nuclear Fuel Cycle Commissioner Ned Xoubi and Daniel Rutherford, contract manager at the US Department of Energy's Pacific Northwest National Laboratory signed the agreement in Washington, DC last week, according to a statement released by the Jordanian embassy in the US.
Under the contract agreement, the US Department of Energy will provide the JAEC with $370,000 for the construction of the advanced storage facility.
Expected to be completed later this year, the storage facility will host Jordan's radioactive waste and nuclear sources in a safe and secure environment for the next five decades.
The Nuclear Regulatory Commission will hold two public meetings May 19 in Wilmington, N.C., to seek comments about specific issues that should be addressed in its environmental review of a proposed uranium enrichment facility.
The meetings will be held at the Warwick Center, Ballroom 1, at the University of North Carolina at Wilmington, from 1 to 4 p.m., and 7 to 10 p.m. NRC staff members will be available for an hour prior to each meeting to speak informally to members of the public.
General Electric-Hitachi Global Laser Enrichment, LLC, (GLE) submitted the environmental report Jan. 30, as one part of an application for a 40-year license to construct and operate a laser-based uranium enrichment facility at the existing General Electric/Global Nuclear Fuels-Americas site near Wilmington. GLE has indicated it intends to file the rest of its application - pertaining to safety aspects of the facility - by the end of June.
Perma-Fix Environmental last month got approval to burn PCB-contaminated rad waste at its Oak Ridge-area facility, and this month received its first shipments.
Larry McNamara, the chief operating officer, confirmed that the company's DSSI (Diversified Scientific Services Inc.) facility near Kingston had received shipments from Paducah, Ky., and Richland, Wash., to be treated at the thermal-boiler system. He also said another shipment had arrived, although he didn't have details, and more are in the works.
McNamara said the company is ready to accept waste loads that might otherwise be treated at the Dept. of Energy's TSCA Incinerator in Oak Ridge, which is scheduled to close later this year.
Some of the waste streams coming to Oak Ridge may need to be segregated at the company's M&EC facility, with the PCB-tainted liquids sent to DSSI for treatment in the thermal boiler, McNamara said. However, he said there are few limits on the types and amounts of wastes that can be treated.
"OAK RIDGE - U.S. Energy Secretary Steven Chu was in town Monday to help celebrate a new $549 million storehouse for the nation's supply of bomb-grade uranium - a high-security facility so stout it reportedly could withstand the impact of a commercial aircraft.
While Chu had words of praise for the massive structure - known officially as the Highly Enriched Uranium Materials Facility - and those who designed and built it, the secretary's most welcome words at the ceremony were those supporting an even bigger project at the Y-12 nuclear weapons plant."
"The Nuclear Regulatory Commission has made available on its Web site an application of International Isotopes Fluorine Products, Inc., for a license to construct and operate a depleted uranium deconversion facility in Lea County, N.M.
International Isotopes submitted the application Dec. 30, 2009, and NRC docketed the application Feb. 23. The proposed facility would process depleted uranium hexafluoride (DUF6) into commercially resalable fluoride products and depleted uranium oxide for disposal. The plant would be capable of deconverting up to 7.5 million pounds per year of DUF6 provided by commercial enrichment facilities throughout the United States.
The application and information on the agency's review process are available at http://www.nrc.gov/materials/fuel-cycle-fac/inisfacility.html.
An opportunity to request a hearing on the application, as well as instructions for filing a request for hearing and petition to intervene were published April 5 in the Federal Register at http://edocket.access.gpo.gov/2010/pdf/2010-7600.pdf. The deadline for requesting a hearing is June 4."
"A peace group says the government and its contractors are starting work on a big project at the Y-12 nuclear weapons plant before it's fully approved and before some environmental impacts have been assessed.
In a statement released Wednesday, the Oak Ridge Environmental Peace Alliance said the Department of Energy should halt all site preparation and preliminary construction activities for the Uranium Processing Facility - a proposed multi-billion-dollar production facility at Y-12.
"DOE is getting the cart way out in front of the horse," Ralph Hutchison, coordinator of OREPA, said by e-mail.
The final Site Wide Environmental Impact Statement required for construction of UPF has not yet been issued, and a Record of Decision is not expected for several months."
The company building a new facility in Newport News to build components for nuclear reactors has decided to end its fuel-assembly production in Lynchburg and expand its operations in Richland, Wash.
Areva said this week it will consolidate the two operations, resulting in a job loss of about 150 in Lynchburg. Areva has operated the Washington facility for 40 years. Areva spokeswoman Judy Thomas told the Tri-City Herald, a newspaper based in Kennewick, Wash., that the 150 employees in Lynchburg will be given first choice for 50 new jobs in Richland, where Areva has 700 employees.
The French-owned energy service company announced last year it will build a $2 billion uranium enrichment plant at Idaho Falls, Idaho. It will produce a raw material for the Richland plant to turn into fuel assemblies for nuclear reactors.
Areva plans to open its Newport News manufacturing plant, a joint venture with Northrop Grumman, by 2011 on the James River waterfront near the shipyard.

"High levels of radioactive cesium have been detected in incinerated ashes at waste disposal facilities in Kashiwa, Chiba Prefecture, in apparent effects from the nuclear crisis at the Fukushima Daiichi power plant, the local municipal office said Monday.
At one waste disposal center in Kashiwa, up to 70,800 becquerels of radioactive cesium per kilogram were detected from ashes collected on June 24 and more than 60,000 becquerels were observed from ashes collected on July 1 and 2, the city office said.
Up to 48,900 becquerels of radioactive cesium were also detected at a facility for burying the ashes from waste disposal centers in the city, while a maximum of 9,780 becquerels were observed at another waste disposal center, the office said.
The figures far exceed the 8,000-becquerel per kilogram cap set by the state for waste disposal facilities to temporarily store such ashes. "
"The Nuclear Regulatory Commission staff has completed a draft environmental statement recommending commission approval of a license for the Global Laser Enrichment facility proposed for the GE complex in Castle Hayne.
The approval was reported in a notice published in Friday's Federal Register, which stated: "The NRC staff preliminarily recommends that, unless safety issues mandate otherwise … the NRC should issue a license" to Global Laser Enrichment to operate a laser-base uranium enrichment facility.
The notice went on to say the "NRC staff in the Office of Nuclear Material Safety and Safeguards, Division of Fuel Cycle Safety and Safeguards is currently completing the safety review of (GE Hitachi's) license application. The safety review is currently scheduled for completion in December 2010.""
