An ultra-high-resolution technique used for the first time to study polymer fibers that trap uranium in seawater may cause researchers to rethink the best methods to harvest this potential fuel for nuclear reactors.

The work of a team led by Carter Abney, a Wigner Fellow at the U.S. Department of Energy’s Oak Ridge National Laboratory, shows that the polymeric adsorbent materials that bind uranium behave nothing like scientists had believed. The results, gained through collaboration with the University of Chicago and detailed in a paper published in Energy and Environmental Science, highlight data made possible with X-ray Absorption Fine Structure spectroscopy performed at the Advanced Photon Source. The APS is a DOE Office of Science User Facility at Argonne National Laboratory.

“Despite the low concentration of uranium and the presence of many other metals extracted from seawater, we were able to investigate the local atomic environment around uranium and better understand how it is bound by the polymer fibers,” Abney said. [Read more…]

Two titans of East Tennessee’s business community were honored Friday with the Muddy Boot Award, given by the East Tennessee Economic Council in an ongoing tribute to individuals who, through their work and activities, build a better community.

This year’s honorees are Jim Henry, deputy governor of the State of Tennessee, a former businessman, legislator, and mayor of Roane County; and Dan Hurst, founder of StrataG, an East Tennessee entrepreneurial company and activist in numerous organizations across the region.

The Council also presented the Postma Young Professional Medal to Ann Weaver, a facilities engineer at Oak Ridge National Laboratory.

Anne Harrington, deputy administrator of the National Nuclear Security Administration, keynoted the event, which was held at the Doubletree Hotel in Oak Ridge. [Read more…]

D. Ray Smith, who is known for his love of Oak Ridge history, could be named honorary city historian on Monday.

Among other activities, Smith is historian at the Y-12 National Security Complex, has been a guide on U.S. Department of Energy tour buses at federal sites in Oak Ridge, writes a weekly newspaper history column, testified before Congress on the Manhattan Project National Historical Park, and frequently photographs community events.

The Oak Ridge City Council will consider naming Smith as honorary city historian during a regular meeting on Monday.

Oak Ridge City Council member Charlie Hensley drafted the proposal. He said Smith is also a leader in the Oak Ridge Heritage and Preservation Association, has been a featured speaker in talks on Oak Ridge heritage, was central to creating a history center at Y-12’s New Hope Center, and serves in a support role for implementation of the Manhattan Project National Historical Park.

Women and minorities encouraged to apply; deadline is Dec. 21, 2015

ORISE is currently accepting applications for the 2016 Mickey Leland Energy Fellowship Program, or MLEF, which is a 10-week summer program for students pursuing degrees in science, technology, engineering, and math.

The MLEF Program provides students who are U.S. citizens with the opportunity to gain and develop research skills by training under the mentorship of program officials and scientists within the U.S. Department of Energy’s Office of Fossil Energy. This program is open to currently enrolled full-time degree-seeking students in a science, technology, engineering, or math (STEM) program at an accredited college or university at the bachelor’s (sophomore or higher), master’s, or doctoral level with a cumulative grade point average of 3.0 or higher.

Participants will support Office of Fossil Energy mission-related research while gaining insight into how DOE is working to meet the energy challenges of the future. Although all eligible candidates are encouraged to apply, the goal of the program is to improve the opportunities for women and minority students in the STEM fields.

The summer program may place students at one of several possible sites, including: [Read more…]

More than 200 scientists from around the world met from October 27 to 29 at the U.S. Department of Energy’s Oak Ridge National Laboratory to provide input on the scientific instruments that would be installed at a proposed Second Target Station, or STS, at the Spallation Neutron Source.

The workshop—which was organized by ORNL’s Neutron Sciences Directorate and drew researchers from 56 universities, research institutions, and other national laboratories—aimed to define the capabilities needed to ensure the next-generation neutron source meets the biggest science challenges.

The Spallation Neutron Source is a DOE Office of Science User Facility that provides the most intense pulsed neutron beams in the world for scientific research and industrial development. [Read more…]

Y‑12 recycles asphalt from UPF site to fix, pave rough roads

Some 23,000 tons of asphalt removed during work this summer at the site of the proposed Uranium Processing Facility has been put to use throughout the Y-12 National Security Complex, officials said.

Potholes and gravel roads are now “paved” with the recycled asphalt that has been ground into a material called base course. Unlike gravel, the material tends to rebind into a solid form as it is packed down, thus sending it back to its former life as asphalt.

“With the tough winter we had earlier this year, we needed to fix some roads around the site,” said Y-12 Road and Grounds Manager Brian Hutson. “This material is good not only for fixing potholes and ruts, but it can be used to essentially pave a gravel road, and that makes it much easier for us to maintain it. Washouts are a big problem on some of our gravel patrol roads.” [Read more…]

Union workers at the Y-12 National Security Complex ratified a new five year-contract on Thursday that includes 3 percent annual wage increases and a $2,500 signing bonus, an official said.

The first 3 percent wage increase goes into effect on Monday, December 7.

The new contract, the first “full-blown” contract since 2004, expires on June 22, 2020, said Steve Jones, president of the Atomic Trades and Labor Council, or ATLC.

Negotiation teams from the ATLC and Consolidated Nuclear Security LLC, which operates Y-12 for the National Nuclear Security Administration, had reached a tentative agreement on Monday on the new five-year labor agreement. [Read more…]

A plan to temporarily close Clark Center Park and Bull Bluff Road in Oak Ridge on Monday, November 30, and on Tuesday, December 1, for tree removal was postponed due to weather, officials said.

The U.S. Department of Energy Oak Ridge Office had identified the trees as potential safety hazards for travelers and visitors on the road and throughout Clark Center Park.

But the tree removal was delayed by rain.

“The temporary closure for the tree removal work will resume once the weather clears in the near future, and the public will be advised at that time,” a press release said.
