The U.S. Department of Energy has awarded a $2.1 million fixed-price contract to a small business based in Michigan, CTI and Associates, to perform asset recovery and demolition work at the old electrical switchyard at ETTP. (DOE photo by Lynn Freeny)

The scope of the work includes removal and recycling of electrical equipment. The switchyard is adjacent to the K-27 Building in west Oak Ridge.

Copper, aluminum, and steel from the yard can be recovered for recycling. CTI has engaged an Alabama subcontractor, TCI, that specializes in electrical recycling. [Read more…]

North Wind Solutions took over the operation of the Transuranic Waste Processing Center in west Oak Ridge in December. The Idaho-based company was awarded the $123 million contract to operate the facility in June.

North Wind replaces Wastren Advantage Inc., which had operated the center since 2010. The Transuranic Waste Processing Center, or TRU Waste Processing Center, is off State Route 95 in southwest Oak Ridge, south of Bethel Valley Road and west of Oak Ridge National Laboratory.

North Wind will continue to process and store transuranic waste at the site until the Waste Isolation Pilot Plant, or WIPP, reopens in New Mexico. WIPP is the only facility in the U.S. that permanently disposes of transuranic waste, or TRU waste. [Read more…]

A new virtual museum helps preserve the history of the former K-25 site, which was built in west Oak Ridge to enrich uranium for atomic bombs during World War II and once had the world’s largest building under one roof.

The K-25 Virtual Museum was launched in November by the U.S. Department of Energy Oak Ridge Office of Environmental Management (OREM) as part of a memorandum of agreement for the interpretation of the historic site now known as East Tennessee Technology Park, or ETTP.

The debut of the online museum coincided with the November 10 signing of an agreement between the Department of Energy and the Department of Interior establishing the Manhattan Project National Historical Park. The Manhattan Project was a top-secret federal effort to build the world’s first atomic weapons during World War II.

The K-25 Virtual Museum can be viewed at http://www.k-25virtualmuseum.org/.

With the production of 50 grams of plutonium-238, researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory have restored a U.S. capability dormant for nearly 30 years and set the course to provide power for NASA and other missions.

Plutonium-238 produces heat as it decays, and it can be used in systems that power spacecraft instruments. The new sample, which is in the same oxide powder form used to manufacture heat sources for power systems, represents the first end-to-end demonstration of a plutonium-238 production capability in the United States since the Savannah River Plant in South Carolina ceased production of the material in the late 1980s.

Researchers will analyze the sample for chemical purity and plutonium-238 content, then verify production efficiency models and determine whether adjustments need to be made before scaling up the process.

“Once we automate and scale up the process, the nation will have a long-range capability to produce radioisotope power systems such as those used by NASA for deep space exploration,” said Bob Wham, who leads the project for the lab’s Nuclear Security and Isotope Technology Division. [Read more…]

Workers have repaired a water leak at the Oak Ridge Research Reactor at Oak Ridge National Laboratory, officials said this week.

The completion of the work was announced by UCOR, a federal cleanup contractor and partnership between URS and CH2M Oak Ridge LLC.

The seep was detected in the reactor’s pool in September 2014. While it did not pose any immediate dangers to workers or the environment, it prompted quick action by the U.S. Department of Energy, which oversees ORNL. DOE asked UCOR, its prime cleanup contractor, to develop and implement a solution to remedy the seep, a press release said. [Read more…]

ORNL technique could set new course for extracting uranium from seawater

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…]

Opinion: AC mayor monitoring proposal for new DOE landfill

Terry Frank

I want the citizens of Anderson County to know as mayor, I have not signed a resolution brought to county commission that requests funding to “offset the financial and environmental burdens” of a proposed expansion of an existing U.S. Department of Energy disposal site, or the creation of a new cell, that for all intents and purposes, would be a twin site.

In my humble and steadfast view, there is no amount of money that could sufficiently offset environmental harm, and I would not put the health, safety, and welfare of the people of Anderson County up for negotiation on a spreadsheet to balance the books of county government.

What I can do, and have for the last three years that I have served as mayor, is closely watch the proposal as it winds its way through a very monitored and specific process. I have participated in community workshops on the subject, held private meetings with leadership and staff of DOE’s Environmental Management Team, have been on site at the current disposal cell, am attentive to all briefings at our regular governmental meetings with DOE and Tennessee Department of Environment and Conservation.

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.

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.
