The U.S. Department of Energy and UT-Battelle could negotiate a five-year contract extension at Oak Ridge National Laboratory, officials said Thursday.

The current contract ends in March 2015. If granted, the extension would allow UT-Battelle to manage the lab though 2020. UT-Battelle is a nonprofit partnership between the University of Tennessee and Battelle Memorial Institute.

U.S. Rep. Chuck Fleischmann, a Tennessee Republican, announced the potential contract extension during a special holiday meeting of the East Tennessee Economic Council on Thursday. ETEC had asked DOE to not rebid the contract—but extend it instead, Fleischmann said.

The congressman said the negotiations over a possible extension were based on a “job well-done” at the premier lab. [Read more…]

ORNL devises recipe to fine-tune silica rod diameters

By controlling the temperature of silica rods as they grow, researchers at Oak Ridge National Laboratory could be setting the stage for advances in anti-reflective solar cells, computer monitors, TV screens, eye glasses, and more.

The goal of fabricating fixed-size one-dimensional silica structures and being able to precisely control the diameter during growth has long eluded scientists. Now, Panos Datskos and Jaswinder Sharma have demonstrated what they describe as the addressable local control of diameter of each segment of the silica rod.

“In nature, many intricate structures develop and grow in response to their environments,” said Sharma, a Wigner Fellow and corresponding author of the Angewandte Chemie International Edition paper that outlines the process. “For example, in addition to genotype, shell shape is also controlled by the local environment in many oysters and scallops.” [Read more…]

DOE, UCOR demolish last piece of K-25, once the world’s largest building

K-25 Building Demolition Final

The last section of the former K-25 Building in west Oak Ridge was demolished on Thursday.

It was once the world’s largest building under one roof, built by the U.S. government in less than two years as part of a top-secret race to build the world’s first atomic bombs during World War II.

Officials say it also helped win the Cold War.

But five years after demolition started, the K-25 Building is gone. Officials, workers, and invited guests watched the last section of the giant building crash to the ground on Thursday.

The mile-long, U-shaped K-25 Building enriched uranium through a process called gaseous diffusion. It was the largest facility in the U.S. Department of Energy complex. Debris shipments are expected to be completed in the spring of 2014.

The $1.1 billion project is under budget and ahead of schedule. [Read more…]

AMSE’s operating contract with for-profit could be replaced by nonprofit

American Museum of Science and Energy

The contract with the for-profit company that runs the American Museum of Science and Energy will change from quarterly to monthly starting Jan. 1, and a museum expert could be hired on an interim basis to assess the museum, its place in the community, and a logical new operating structure.

The museum is now funded by the U.S. Department of Energy at a cost of about $1.5 to $1.6 million per year, said David Keim, communications director at Oak Ridge National Laboratory. Revenues from the gift shop, admissions, and programs add up to about $300,000 per year.

But officials have long said that the department should not be operating the museum.

“It’s always been a government-funded operation,” Keim said. But, “DOE is not in the museum business.”

In June, a group of museum directors brought to Oak Ridge from around the country recommended that the museum be run by a community-based nonprofit organization—not DOE and not a for-profit company, Keim said. [Read more…]

USEC, an international uranium fuel company that has operations in Oak Ridge, learned Wednesday that the federal government could extend its American Centrifuge research, development, and demonstration program for three months.

In a press release, USEC said the U.S. Department of Energy is prepared to extend the program for three months beyond Jan. 15, 2014, subject to Congressional appropriations.

DOE and USEC will share costs of the program on an 80 percent/20 percent basis for a total funding level of about $10 million per month, the release said. [Read more…]

If scientists can control cellular functions such as movement and development, they can cripple cells and pathogens that are causing disease in the body.

Supported by National Institutes of Health grants, researchers at Oak Ridge National Laboratory, the University of Tennessee, and the UT-ORNL Joint Institute for Computational Sciences discovered a molecular “switch” in a receptor that controls cell behavior using detailed molecular dynamics simulations on a computer called Anton built by D.E. Shaw Research in New York City. To study an even larger signaling complex surrounding the switch, the team is expanding these simulations on Titan—the nation’s most powerful supercomputer, managed by the Oak Ridge Leadership Computing Facility at ORNL.

Researchers identified the molecular switch on Anton (which was designed to perform speedy molecular dynamics simulations) by simulating 140,000 atoms that make up the signaling part of the Tsr chemoreceptor that controls motility in E. coli. Like other receptors, Tsr spans the cell membrane, communicating to proteins inside the cell in order to respond to threats or opportunities in the environment. [Read more…]

Once the world’s largest, K-25 Building will be completely demolished Thursday

It was once the world’s largest building under one roof, but on Thursday, federal officials expect to complete demolition work at the K-25 Building in west Oak Ridge.

K-25 was built during World War II to enrich uranium for the world’s first atomic bombs as part of the top-secret Manhattan Project. After the war, it enriched uranium for nuclear weapons and commercial nuclear power plants.

But the site shut down in the mid-1980s, and demolition work on the K-25 Building started five years ago, in December 2008, under former cleanup contractor Bechtel Jacobs.

Officials and workers expect to tear down the last remaining piece of K-25 starting at about 11 a.m. Thursday. They have invited media to attend to witness the historic event. [Read more…]

DOE announces new investment in small modular reactors

The U.S. Department of Energy last week announced a second round of funding for small modular reactors.

The first award, announced earlier this year, provided support to Babcock and Wilcox Co. through a program that could result in small modular reactors at the former Clinch River Breeder Reactor site in west Oak Ridge. In November, B&W announced it had already invested more than $360 million in that project, and the North Carolina company was looking for investors and possibly majority owners.

DOE said the new award was given to Oregon-based NuScale Power LLC to support a new project to design, certify, and help commercialize innovative small modular reactors in the United States.

The department said the reactors could provide clean, safe, and cost-effective nuclear energy, and build on President Obama’s Climate Action Plan to “continue America’s leadership in clean energy innovation.” [Read more…]

House-passed budget could avoid second shutdown; Senate may vote this week

Y-12 National Security Complex Sign

A bipartisan budget bill being considered in Congress could avoid a second government shutdown and provide relief to federal employees and government contractors in Oak Ridge, including at the Y-12 National Security Complex, which was prepared to furlough up to 3,600 workers during the first shutdown in October.

The U.S. House of Representatives has passed a budget bill that could avoid a second government shutdown in mid-January, a development that will likely offer some relief to federal employees and government contractors in Oak Ridge—and to the businesses that support them.

U.S. Rep. Chuck Fleischmann, a Tennessee Republican, said he supported the Bipartisan Budget Act of 2013 in the House on Thursday.

“Tonight, the House took a modest step toward reforming spending and setting our government on a more stable path,” said Fleischmann, a second-term congressman whose district includes Oak Ridge.

But the bill still has to pass the deeply divided Senate, which is preparing to take up the budget bill this week. The Washington Post reported that Democrats are still trying to come up with the 60 votes necessary to break a GOP-led filibuster in the Senate. [Read more…]
