The U.S. Nuclear Regulatory Commission will have a public meeting in Oak Ridge next week to accept public comments about the environmental review for a proposed nuclear fuel facility at Horizon Center.

It would be the first manufacturing facility of its type in the United States. It has been proposed by TRISO-X, which wants to manufacture coated particle uranium fuel for new types of nuclear reactors—advanced and small modular reactors. The fuel could power reactors for electrical and chemical use, the U.S. Department of Defense, and the National Aeronautics and Space Administration (NASA).

Power to TRISO at Horizon could cost $13 million

This map shows the potential route of 69-kilovolt overhead power lines for the TRISO-X nuclear fuel facility at Horizon Center in west Oak Ridge, starting at the substation (SUB) on the south side of Highway 95/58 (lower right), continuing up Novus Drive (center right), crossing onto Horizon Center land, and then running east (to the right) on the back side of Site 6 (open area at upper right).

Building a new substation and electrical lines to supply power to a nuclear fuel company could cost $13 million, Oak Ridge officials said in December.

The nuclear fuel company, TRISO-X, needs about 32 to 35 megawatts of electricity at Horizon Center in west Oak Ridge. That would make the company the city’s biggest electrical customer. (Oak Ridge National Laboratory and Y-12 National Security Complex get most of their power directly from Tennessee Valley Authority.)

The U.S. Nuclear Regulatory Commission announced Friday that it will prepare an environmental impact statement for a proposed nuclear fuel fabrication facility in Oak Ridge that could help power advanced reactors for electrical and chemical use, the U.S. Department of Defense, and the National Aeronautics and Space Administration (NASA).

The project could partially benefit from last year’s federal infrastructure law, specifically about $1.1 billion appropriated for a clean energy supply.

This story was last updated at 5:30 a.m. Sept. 7.

Two companies that have operations or employees in Oak Ridge are exploring a collaboration for the possible production of fuel for advanced nuclear reactors.

The two companies, X Energy LLC and Centrus Energy Corporation, announced Wednesday that they have signed a memorandum of understanding for the potential collaboration.

They are expected to put together a business plan for the fuel fabrication business. It’s not clear how long that might take, said Jeremy Derryberry, Centrus Energy senior communications manager.

But the companies are working toward the development of a fuel fabrication facility that could possibly be in Oak Ridge, where Centrus, formerly known as USEC, has had operations for about 15 years.

“We really think that Oak Ridge can be a nexus for the advanced reactor industry in the U.S. going forward,” Derryberry said in a telephone interview Wednesday.

Centrus, ORNL agree on $25 million contract for work on gas centrifuge uranium enrichment technology

Six months after signing one contract, Centrus Energy Corporation and UT-Battelle LLC have agreed on a new contract for engineering and testing work on technology that uses gas centrifuges to enrich uranium.

Enriched uranium can be used in nuclear power plants and in nuclear weapons, as fuel for nuclear naval vessels, and to ensure a tritium supply, which is needed to maintain the effectiveness of America’s nuclear deterrent, a press release said.

The new Centrus Energy-UT-Battelle contract is valued at about $25 million, and it runs through September 30, 2017. Under this new contract, Centrus scientists, engineers, and operators will “use the company’s unique facilities in Oak Ridge to develop and test technology improvements to reduce costs, improve manufacturability, and enhance the long-term reliability of U.S. uranium enrichment technology,” the press release said.

UT-Battelle operates Oak Ridge National Laboratory for the U.S. Department of Energy.

The uranium enrichment technology is known as the American Centrifuge technology. It’s expected to support future national security and energy security needs, the press release said. [Read more…]

DOE explores options for enriched uranium technology for national security

USEC, UT-Battelle to preserve centrifuge enrichment capabilities on interim basis

USEC and UT-Battelle have signed a $33.7 million, five-month contract to continue operating centrifuges and conducting research and development activities on a uranium enrichment project deemed important for national security and possible commercial use.

The agreement with UT-Battelle, which manages Oak Ridge National Laboratory, was signed May 1. The five-month term ends Sept. 30. The new agreement includes options for two six-month extensions valued at about $41.7 million each. The total price of the contract with the options is roughly $117 million.

USEC, which is now an ORNL subcontractor, previously performed research, development, and demonstration work on the project, the American Centrifuge Project, under an agreement with the U.S. Department of Energy that had been in place since June 12, 2012. That cost-sharing agreement expired April 30. [Read more…]

USEC bankruptcy filing won’t affect daily operations in Oak Ridge, company says

The Chapter 11 bankruptcy filing and financial restructuring plan that USEC Inc. announced last week will not affect daily operations in Oak Ridge or the American Centrifuge Project, a company spokesman said Monday.

The bankruptcy filing and financial plan are a restructuring of the balance sheet of the parent company, USEC Inc., spokesman Paul Jacobson said. He said the company is trying to strengthen its balance sheet and be a stronger sponsor of the American Centrifuge Project, a “next-generation” U.S. uranium enrichment technology. USEC Inc. is a global energy company that is a leading supplier of enriched uranium fuel for commercial nuclear power plants.

The company currently has 304 people working on the centrifuge program in Tennessee. In Oak Ridge, workers take part in centrifuge operations, testing, and manufacturing.

“This plan for restructuring our debt and equity will have no effect on our employees, who will continue to receive paychecks and benefits in the ordinary course,” Jacobson said. “As we have communicated to our employees previously, some employees will be impacted by several ongoing initiatives that are unrelated to the restructuring.” [Read more…]

The Babcock and Wilcox Co. has already invested more than $360 million in a project that could result in a small nuclear reactor in west Oak Ridge, and now the North Carolina company is looking for investors and possibly majority owners.

The mPower small modular reactor, or SMR, program is expected to have a nuclear power plant operating at the former Clinch River Breeder Reactor Site by 2022. Initially, it could have two small reactors, a “twin pack,” and produce 360 megawatts.

On Wednesday, Marshall Cohen, B&W vice president for government affairs and communications, said the company is seeking major corporations who are interested in taking a “strong position,” up to and including ownership, including majority ownership.

“We would reduce our ownership to one that really matches the scope of work going forward,” Cohen said. [Read more…]

UT receives DOE funds, ORNL help for spent nuclear fuel studies

KNOXVILLE—The question of what to do with spent nuclear fuel in the U.S. has never been definitively answered. A University of Tennessee in Knoxville professor has received funding from the U.S. Department of Energy to develop new capabilities for evaluating potential alternatives to directly disposing of used fuel.

The award is part of the DOE’s 2013 Nuclear Energy University Programs which is awarding $42 million to 38 American universities and colleges for nuclear energy research and development projects focused on developing innovative solutions.

A proposal by Steven Skutnik, assistant professor in nuclear engineering, was awarded $755,000 to develop new capabilities for a fuel cycle simulator called CYCLUS by building on an Oak Ridge National Laboratory software package for nuclear fuel modeling called ORIGEN. [Read more…]

Deliveries are 95 percent complete, represents 19,000 nuclear warheads converted to civilian use

WASHINGTON, D.C.–The National Nuclear Security Administration on Monday announced it has monitored the elimination of more than 475 metric tons of Russian highly enriched uranium, or HEU, under a landmark nuclear nonproliferation program, commonly known as Megatons to Megawatts.

The rough equivalent of 19,000 nuclear weapons has been permanently eliminated, the NNSA said in a press release. [Read more…]
