MPs question DOE's contract with Centrus Energy subsidiary for HALEU fuel fabrication system:
The chairs and ranking members of two House Science, Space, and Technology subcommittees have asked the Department of Energy to justify the October award of a $115 million contract to Centrus Energy to demonstrate technology for producing a specialized nuclear fuel for advanced reactors. The bipartisan quartet questioned DOE's decision to bypass competitive bids for the work; expressed skepticism over the need for the fuel, known as high-assay low-enriched uranium (HALEU); and asked why DOE's civilian nuclear program was tapped to pay for a program that ultimately will be of far greater benefit to defense applications.
HALEU is enriched in isotope uranium-235 up to 19.75% -- just below the 20% threshold that defines highly enriched uranium (HEU). Some designs for advanced reactors would require enrichment levels above the 4–5% that fuels the existing fleet of US commercial reactors.

Commercialization of American Centrifuge Plant not economically viable without additional government support
USEC Inc. stated this week that additional government funding might be needed beyond the American Centrifuge Plant's ongoing research, development and demonstration work to keep the project moving toward full commercial deployment.
The company talked about the need in its announcement of third-quarter financial results this week, stating it has been experiencing cost pressures because of delays over time in deploying the centrifuge project amid changing market conditions.
"The economics of the project are severely challenged by the current supply/demand imbalance in the market for low-enriched uranium and related downward pressure on spot market prices for (Separative Work Units, the measure of product produced that is used to fuel nuclear power plants), which are now at their lowest levels in more than a decade," a news release from the company stated. "At current market prices, we do not believe that our plans for (the American Centrifuge Plant) commercialization are economically viable without additional government support."

House Appropriations subcommittee approves $100 million for American Centrifuge project
A key House committee yesterday (Apr. 18) agreed to include $100 million in a spending bill for the struggling uranium-enrichment plant in Piketon, a move that could keep it alive.
The House Appropriations subcommittee on energy and water approved spending the money on the American Centrifuge Plant at the request of House Speaker John Boehner, R-West Chester, and Rep. Steve LaTourette, R-Bainbridge Township, according to a Capitol Hill source.
The move by the subcommittee is likely to be approved by the full House.
The $100 million is just part of what USEC - a Maryland-based company that would operate the plant - has said it needs to launch the project. USEC had urged the Obama administration during the past three years to approve a $2 billion loan guarantee.

American Centrifuge project offered short-term funding fix
Federal energy officials have agreed to give USEC access to $44 million in research and development funds needed for its Piketon uranium enrichment initiative.
That money is enough to keep USEC's American Centrifuge Project alive for another few months, buying crucial time for Congress to find another $106 million needed to ensure the technology is viable and push the project toward commercialization.
In a letter to Sen. Sherrod Brown on Friday (Jan. 13), Energy Secretary Steven Chu said his department would assume liability for $44 million of USEC assets in the form of uranium "tails," a byproduct of enrichment. That will free up money on USEC's books, allowing the company to continue funding the centrifuge research in the short run.

The Department of Energy said Friday (Oct. 21) that it plans to work with the developer of a uranium enrichment project in southern Ohio on research and development to reduce technical and financial risks that have held up the developer's application for a $2 billion loan guarantee.
The loan guarantee application from USEC Inc. is still pending. But, the government and the Bethesda, Md. -based developer of the planned American Centrifuge Plant in Piketon have agreed on a potential project that would involve testing and building clusters of machines used to enrich uranium, Richard Kauffman, senior adviser to the Energy secretary told The Associated Press on Friday.
The government's part of the funding of the research and development would be capped at $300 million and would have to be approved by congressional committees.

First cascade of "Production-Ready" centrifuges begins operation at USEC's American Centrifuge Plant project
On March 16, 2010, USEC Inc. announced a major step in the American Centrifuge program with the operation of a cascade of AC100 centrifuge machines in a commercial-plant configuration in Piketon, Ohio. USEC refers to its production centrifuge machine design as the AC100 series centrifuge machine.
USEC gets $45 million in federal aid for American Centrifuge Plant - in exchange for depleted uranium tails [!]
Its bid for a $2 billion federal loan guarantee is still pending, but the company trying to build a $3.5 billion uranium-enrichment plant in Piketon, Ohio, will get a promised infusion of $45 million from the Department of Energy.
The promise to USEC was made in August when the Energy Department turned down the loan-guarantee application, with federal officials saying they didn't think the technology had been proven commercially viable.
USEC says the loan guarantee is critical to its ability to build the plant, and the company won a temporary reprieve and the ability to reapply for the loan guarantee at a later date.
That reapplication is expected to happen this year. In the meantime, the $45 million will help USEC keep working on the plant's technology, and the company says it will match the federal money with $45 million of its own.
The federal cash comes from the Energy Department assuming $45 million worth of depleted uranium "tails" counted on USEC's books as a liability [!].

EPA finds concern on proposed depleted uranium disposition unresolved
By letter dated June 19, 2006, U.S. Environmental Protection Agency finds that concerns regarding the depleted disposition remain unresolved in the Final Environmental Impact Statement for the proposed American Centrifuge plant (ACP):
"The U.S. Department of Energy's planned depleted uranium hexafluoride (DUF6) conversion facility may not have sufficient capacity to process (1) the substantial amounts of DUF6 to be generated by ACP, plus (2) the substantial amounts of DUF6 existing at the Portsmouth Reservation."
"Depleted uranium hexafluoride (DUF6) is a corrosive and reactive hazardous material until converted into a more stable
form for long-term storage and disposal. DOE has plans to build a DUF6
conversion facility at Portsmouth to process the 450,000 metric tons of DUF6
generated from 50 years of previous uranium enrichment activities at the site,
expected to operate until 2024. The ACP is expected to operate until 2039
and generate 571,000 metric tons of DUF6.
DOE is likely to be the only entity performing DUF6 conversion on this large
of a scale due to their obligation to accept DUF6 tails from generators under
the USEC Privatization Act. If DOE is to process all of the DUF6 from past
operations, and process all of the ACP-generated DUF6, then, as NRC's
response to comments state, DOE would have to install additional conversion
lines, or extend the DUF6 conversion facility's operating life from 2024 to
2077. What this amounts to is that if DOE doesn't have the adequate capacity
to process DUF6 at rates adequate to address legacy inventories and the
ACP's DUF6 generation rate, corrosive and reactive hazardous DUF6 may
require storage and management for up to 38 years until converted into a safe
and stable form. [...]" (emphasis added)

DOE releases Environmental Assessment for the Leasing of Centrifuge Facilities and Equipment to USEC Inc.
DOE/EA-1451, Environmental Assessment for the Leasing of Facilities and Equipment to USEC Inc., October 2002.
"The U.S. Department of Energy (DOE) Oak Ridge Operations Office (DOE-ORO) has prepared this Environmental Assessment (EA) for the lease of facilities and equipment to USEC Inc. (USEC), which would be used in its Gas Centrifuge Research and Development (R&D) Project at the East Tennessee Technology Park (ETTP) [hereinafter referred to as the USEC EA]. The USEC EA analyzes the potential environmental impacts of DOE leasing facility K-101 and portions of K-1600, K-1220 and K-1037 at the ETTP to USEC for a minimum 3-year period, with additional option periods consistent with the Oak Ridge Accelerated Clean-up Plan (ACP) Agreement. In July 2002, USEC notified DOE that it intends to use certain leased equipment at an off-site facility at the Centrifuge Technology Center (CTC) on the Boeing Property. The purpose of the USEC Gas Centrifuge R&D Project is to develop an economically attractive gas centrifuge machine and process using DOE’s centrifuge technology. This EA is prepared in accordance with the National Environmental Policy Act (NEPA) of 1969, P.L. 91-190, 42 U.S. C. §4321 et seq."

USEC and DOE sign agreement on construction of centrifuge enrichment plant
The Energy Department announced on June 18, 2002, it had signed an agreement with USEC Inc., of Bethesda, Md., for the company to build a new centrifuge uranium enrichment plant in either Kentucky or Ohio within a decade.
Other terms of the agreement cover the delivery of Russian warhead material under the Megatons to Megawatts program, the continued operation of the Paducah Gaseous Diffusion Plant until the new plant is operational, and the remediation or replacement of out-of-specification uranium transfered to USEC. In exchange for USEC's expected expenses of $21 million necessary for the latter, the government will take possession of three years worth of depleted uranium tails from the USEC production process.

USEC revives centrifuge enrichment technology plans
On October 2, 2001, Dennis Spurgeon, Executive Vice President & Chief Operating Officer of USEC Inc. presented a speech at Nuclear Energy Institute's International Uranium Fuel Seminar 2001 on USEC's efforts to develop more efficient enrichment technologies. While, in the long term, USEC still pursues the development of the SILEX laser-based enrichment technology, USEC now also is working to revive in the mid term the centrifuge enrichment project shelved by DOE in 1985. USEC believes that, with today's technology, the centrifuges developed by DOE can now be manufactured at significantly lower cost, reducing the capital cost per SWU to about half that of competitors.
USEC plans to demonstrate centrifuge performance in Oak Ridge, Tennessee. Based on the success, a "lead cascade" of centrifuges will be built and operated at a gaseous diffusion plant. Later, construction of a commercial centrifuge plant is planned, incrementally replacing the current gaseous diffusion enrichment capacity.
