The National Nuclear Security Administration is leading an effort to develop and qualify a new fuel that will allow high-performance research reactors in the United States that currently use highly enriched uranium to be converted to reactors that use low-enriched uranium fuel.

The research reactors that could be converted include the High Flux Isotope Reactor at Oak Ridge National Laboratory.

The goal is to develop a fuel that cannot be used in a nuclear weapon. The research reactors perform unique science and are a critical part of the U.S. nuclear complex, but all together, they use 200 kilograms of highly enriched uranium each year. That’s enough material for at least eight weapons, according to the NNSA.

On Wednesday, the NNSA said it has presented the U.S. Nuclear Regulatory Commission with a preliminary report on uranium-molybdenum (U-Mo) monolithic fuel. The report contains data about the performance of the new fuel in a reactor and how it holds up under a variety of conditions. [Read more…]

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.

The United States Nuclear Regulatory Commission will seek public comments on what environmental matters it should consider during its review of the early site permit application for the Clinch River Nuclear Site in west Oak Ridge.

The NRC will seek the comments during two meetings in Oak Ridge on Monday that are part of the process used to develop an environmental impact statement.

The first meeting is from 1-4 p.m. Monday, May 15, in the Pollard Technology Conference Center Auditorium at 210 Badger Avenue in Oak Ridge. The second meeting is from 6-9 p.m. that same day.

The Tennessee Valley Authority submitted an application last May for the early site permit for small modular nuclear reactors, or SMRs, at the Clinch River Site in west Oak Ridge. The early site permit application is for two or more SMRs. The NRC accepted the application for “docketing and detailed technical review” in December.

A specific reactor design has not been selected. TVA has identified parameters for a surrogate nuclear plant, and the NRC will use them to evaluate the site’s suitability for building and operating a new nuclear plant. [Read more…]

The Tennessee Valley Authority submitted an application last May for an early site permit for small modular nuclear reactors, or SMRs, at the Clinch River Site in west Oak Ridge.

The U.S. Nuclear Regulatory Commission, or NRC, accepted the application for “docketing and detailed technical review” in December.

The early site permit application is for two or more SMRs.

A specific reactor design has not been selected. The NRC said TVA has identified parameters for a surrogate nuclear plant, and the NRC will use them to evaluate the site’s suitability for building and operating a new nuclear plant.

“If NRC determines that the site is suitable for the building and operation of a new nuclear plant, prior to building and operation of a plant at the site, NRC would need to review and approve an additional application from TVA (either a combined license (COL) or a construction permit (CP)) that includes a specific reactor design,” the NRC said on its website.

The project’s timeline, which includes a detailed technical review, is now in the hands of the NRC, and it will likely take several years, TVA spokesperson Scott Brooks said Friday. [Read more…]

The small modular nuclear reactors being evaluated for the Clinch River Site in west Oak Ridge could provide an emissions-free fuel source, but it could be a decade or so before they start operating. And that’s assuming all goes according to plan, officials said Tuesday.

The Tennessee Valley Authority is evaluating the possibility of building the small modular reactors, or SMRs, at the 1,200-acre Clinch River Site. To help prepare for the project, TVA plans to apply for what is known as an early site permit, or ESP, for the Oak Ridge project from the U.S. Nuclear Regulatory Commission by May 12.

The NRC had two public meetings at Oak Ridge Associated Universities on Tuesday to discuss the safety and environmental review process related to the TVA permit application.

The early site permit application will allow the NRC to evaluate site safety, the environment, and emergency preparedness for future SMRs at the Clinch River Site. That site is in west Oak Ridge just north of the Clinch River and Interstate 40, south of Heritage Center (the former K-25 site), and between Highway 95 and Highway 58 in a bend of the Clinch River.

The review of TVA’s application for an early site permit could take about three years, and maybe longer if any groups raise legal challenges, said Scott Burnell, NRC public affairs officer. [Read more…]

Reminder: The U.S. Nuclear Regulatory Commission will have two public meetings in Oak Ridge today (Tuesday, April 12). The meetings are to discuss the safety and environmental review process related to a Tennessee Valley Authority permit application for small modular reactors at the Clinch River Nuclear Site in west Oak Ridge.

TVA expects to submit what is known as an early site permit, or ESP, application by May 12.

One of the topics to be discussed today is how and when the public may participate in the NRC review process, if desired, a NRC meeting notice said. “The public is encouraged to ask questions about the NRC review process for this ESP Application,”

Two sessions are scheduled in the auditorium of the Pollard Technology Conference Center at 210 Badger Avenue in Oak Ridge.

The first is scheduled from 1-4 p.m. Tuesday, April 12, and the second is scheduled from 6-9 p.m. Prior to each formal session, there will be an informal one-hour open house to give the public an opportunity to speak informally with the NRC staff. [Read more…]

The small nuclear reactors that could be built along the Clinch River could provide enough electricity to power several cities the size of Oak Ridge. They could also be, depending upon the timing, the first commercial reactors of their type in the United States.

They’re known as small modular reactors, or SMRs. They could generate 80 to 200 megawatts each. One hundred megawatts is enough to power about 60,000 homes. Oak Ridge has about 12,000 homes.

Several companies are working on SMR designs, but so far none have been certified by the U.S. Nuclear Regulatory Commission, said Jim Hopson, public relations manager for the Tennessee Valley Authority.

By May 12, TVA plans to submit an application to the NRC for what is known as an early site permit to build SMRs on the Clinch River Site in west Oak Ridge. Hopson likened an early site permit, or ESP, to a pre-approval for a home loan, although he said that is an oversimplification.

“It’s similar to pre-approving yourself for a loan,” Hopson said Friday. “You get the preliminaries out of the way.” [Read more…]

A centrifuge demonstration is complete in Piketon, Ohio, and the workforce there will be reduced, but  research, engineering, and testing work will continue in Oak Ridge, Centrus Energy Corporation announced Friday.

The company, which is based in Bethesda, Maryland, said it has completed operations of its three-year demonstration cascade of American Centrifuge machines at its facility in Piketon, Ohio. Now, it will demobilize the demonstration cascade and reduce its workforce at Piketon starting with the layoff of about 60 employees during the week of February 29, Centrus said.

Centrus currently has more than 120 employees working at two dedicated facilities in the Oak Ridge area to engineer, design, and test improvements in full-size machines operating in individual test stands, a press release said. The company’s scientists and engineers will continue to improve the reliability and manufacturability of centrifuge machines for potential future applications, the release said. [Read more…]

Three groups seek info on plan to bring spent nuke fuel to ORNL

Three nuclear watchdog organizations have filed a Freedom of Information Act request with the U.S. Nuclear Regulatory Commission seeking information about plans to ship high burn-up commercial spent nuclear fuel from the North Anna power reactor in Virginia to Oak Ridge National Laboratory in Tennessee, a press release said. The three organizations are Savannah River Site Watch in Columbia, South Carolina; Snake River Alliance Education Fund in Pocatello, Idaho; and the Oak Ridge Environmental Peace Alliance in Oak Ridge.

The groups filed the FOIA request after discovering a letter approving a shipping route from North Anna to Oak Ridge, the press release said. It said the letter provides little information about the specifics of the route or the timing of the proposed shipment.

“We asked for a map of the route two weeks ago,” said Ralph Hutchison, coordinator of OREPA. “So far, we’ve received nothing. So we are resorting to the formal—and more expensive for the government—FOIA process to get information.”

Tom Clements, director of SRS Watch, filed the FOIA on behalf of the three organizations. The Savannah River Site was initially under consideration for the research project. [Read more…]

Oak Ridge National Laboratory intends to extend its contract with Centrus Energy Corporation for research on uranium enrichment centrifuges, but at a reduced level, with funding cut by about 60 percent, the company said Friday. Layoffs could be required, Centrus said in a press release.

The contract extension continues technology development activities at Oak Ridge facilities for advanced uranium enrichment centrifuges, but revenues won’t be used for operations in Piketon, Ohio, the press release said.

The new contract will cover a one-year period from October 1, 2015, to September 30, 2016, with the possibility for additional extensions, the release said.

It said the U.S. Department of Energy’s decision to provide reduced funding will support continued developments of the company’s American Centrifuge technology—which has long-term importance for national and energy security. [Read more…]
