The U.S. Department of Energy is requesting more time to complete projects to commemorate the historic contributions of the former K-25 site in west Oak Ridge.

Built during World War II, the K-25 site helped enrich uranium for the first atomic bomb used in wartime as part of the top-secret Manhattan Project. The plant continued to enrich uranium for nuclear weapons and commercial nuclear power plants after the war, and those who have worked at the site have said it helped win the Cold War.

The history of the site will be honored by preserving the concrete slab of the former K-25 Building, building a Viewing Tower and replica Equipment Building on the south side of the building site, and opening a K-25 History Center on the second floor of the adjacent Oak Ridge Fire Station Number 4.

A historical interpretation agreement was signed in August 2012. But it expires this August. And the roughly $20 million worth of projects won’t be complete by then.

DOE is making “good progress,” but “the reality is we need a little more time,” said Dave Adler, acting deputy manager for DOE’s Oak Ridge Office of Environmental Management. Adler and Steve Cooke, K-25 preservation coordinator for DOE, briefly discussed the proposed amendment to the agreement during a Tuesday evening work session with the Oak Ridge City Council.

The U.S. Nuclear Regulatory Commission will have two public meetings on June 5 to discuss the draft environmental impact statement for the Clinch River Nuclear Site in west Oak Ridge.

The two public meetings will be in Kingston, and they will be transcribed, the NRC said.

They will allow the public to comment on the draft environmental impact statement, or DEIS, for the early site permit application for the Clinch River Nuclear Site, where small modular nuclear reactors could eventually be built. The DEIS is available here. [Read more…]

Centrus, ORNL contract continues uranium enrichment technology work in Oak Ridge

A $16 million contract signed by Centrus Energy Corporation and and UT-Battelle LLC will continue work on gas centrifuge uranium enrichment technology at Centrus facilities in Oak Ridge, the company announced Monday.

The work is on the AC100, a U.S. gas centrifuge uranium enrichment technology.

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

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, officials have said previously.

The new Centrus-ORNL contract is valued at $16 million, with payments made when certain defined milestones are completed, Centrus said in a press release on Monday. The contract runs through September 30, 2018.

“Under the contract, Centrus’ scientists, engineers, and operators will test improvements developed by the company for the AC100 centrifuge machine in specialized facilities in Oak Ridge,” the press release said. “Centrus has worked under contract with ORNL since 2014 to improve the AC100 gas centrifuge technology to support national security and energy security needs.” [Read more…]

Historic day: Last wall to be demolished at last of big five uranium-enriching buildings at ETTP (K-25)

K-27 Demolition Aug 17 2016 Freeny

The last wall of the last of the big five buildings once used to enrich uranium at the former K-25 site will be demolished Tuesday.

Demolition on the last building, the K-27 Building, started in February.

The other four buildings—K-25, K-29, K-31, and K-33—were demolished between 2006 and 2015. All five of the huge buildings once used a process called gaseous diffusion to produce highly enriched uranium for atomic weapons and commercial nuclear power plants, starting during World War II and continuing through the Cold War. The largest was K-25, a mile-long U-shaped building.

When K-27 demolition is complete, it will be the first time that all of a site’s uranium-enriching gaseous diffusion buildings will have been cleaned up anywhere in the world, officials said.

“Demolition eliminates environmental hazards and prepares the land for productive reuse through deindustrialization,” a media advisory said. [Read more…]

Demolition work on K-27, last of big 5 uranium-enrichment buildings, to be complete this month

Demolition work should be complete this month on K-27, the last of the big five buildings once used to enrich uranium for nuclear weapons and commercial nuclear power plants at the former K-25 site in west Oak Ridge, officials said last week.

Demolition work started on K-27 in February.

Like the other four buildings that have already been demolished, the four-story, 383,000-square-foot K-27 building once used a process known as gaseous diffusion to enrich uranium.

The demolition is part of Vision 2016. That’s the plan by the U.S. Department of Energy Office of Environmental Management, or EM, to remove all five gaseous diffusion buildings from the site by the end of the year.

Federal officials said it’s the first time in the world that a uranium enrichment complex has been cleaned and removed. [Read more…]

ORNL to extend contract for uranium centrifuge work, but at reduced level; could require layoffs

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…]

USEC centrifuge agreement extended, but future uncertain as workers receive WARN notices

The American Centrifuge Project, a program that would enrich uranium for commercial nuclear power plants and has operations in Oak Ridge, got a little extra time this week.

Several billions have already been spent and funding was set to expire April 15, but USEC announced Tuesday morning that the research, development, and demonstration agreement was extended through April 30. That was done at no additional cost to the taxpayer through “prudent management of existing program funds by USEC,” the company said in a press release.

In the meantime, USEC said it continues its discussions with Oak Ridge National Laboratory, which could take over the management of the project for national security purposes. The DOE takeover was announced by Energy Secretary Ernest Moniz during a House Appropriations subcommittee hearing earlier this month.

The future of the project is not clear and several hundred workers have received notices that they could be laid off. On Friday, USEC Inc. spokesperson Paul Jacobson said the 60-day notices, which were effective March 19, were sent to 174 USEC employees in the Oak Ridge area and a total of 400 workers. Most of the other workers are in Piketon, Ohio, but there are also a few at USEC headquarters in Bethseda, Md. [Read more…]
