Roughly 25 acres of land that once housed a machine shop and supporting buildings at Heritage Center has been transferred to an economic development organization that finds new uses for former federal property.

The property transfer from the U.S. Department of Energy to the Community Reuse Organization of East Tennessee was celebrated in a Wednesday afternoon ceremony. It’s the 12th transfer from DOE to CROET, and the two dozen acres were signed over to CROET for private-sector use.

Among the speakers at Wednesday’s ceremony were U.S. Rep. Chuck Fleischmann, a Republican whose district includes Oak Ridge, and David Klaus, DOE’s deputy undersecretary for management and performance.

“The reindustrialization program in Oak Ridge has not only been an economic development catalyst for the region, it is saving tax payers millions of dollars as the federal government transfers underutilized assets to the private sector,” Fleischmann said.

The transfers of the parcels, officially known as ED-11 and ED-12, have been in the works for at least a few years. Lawrence Young, CROET president and chief executive officer, said there will some infrastructure improvements to make the property ready for development. Part of the property once housed Building 1401, an old machine shop that has now been demolished. [Read more…]

Researchers at Oak Ridge National Laboratory have developed a new and unconventional battery chemistry aimed at producing batteries that last longer than previously thought possible.

In a study published in the Journal of the American Chemical Society, ORNL researchers challenged a long-held assumption that a battery’s three main components—the positive cathode, negative anode, and ion-conducting electrolyte—can play only one role in the device.

The electrolyte in the team’s new battery design has dual functions: It serves not only as an ion conductor but also as a cathode supplement. This cooperative chemistry, enabled by the use of an ORNL-developed solid electrolyte, delivers an extra boost to the battery’s capacity, and extends the lifespan of the device.

“This bi-functional electrolyte revolutionizes the concept of conventional batteries and opens a new avenue for the design of batteries with unprecedented energy density,” said ORNL’s Chengdu Liang. [Read more…]

The field work is complete on 27 cleanup projects at three federal sites in Oak Ridge that used $751 million in Recovery Act funds.

The U.S. Department of Energy’s Oak Ridge Office of Environmental Management, or EM, announced the end of the field work on Thursday.

“We’re done knocking down buildings and with all the work in the field,” said Mike Koentop, executive officer in Oak Ridge Office of Environmental Management. “We have paperwork left to do to close out projects.”

The American Recovery and Reinvestment Act of 2009, also known as the Recovery Act or stimulus bill, was passed by Congress and signed by President Barack Obama in February 2009. It was meant to help stimulate an economic recovery during the depths of the Great Recession, and it was intended to address long-neglected infrastructure projects and programs.

In Oak Ridge, the Recovery Act funding paid for several demolition projects such as the demolition of the 1.4-million-square-foot K-33 Building at the East Tennessee Technology Park and other projects ranging from mercury reduction at the Y-12 National Security Complex to transuranic waste processing at Oak Ridge National Laboratory.

USEC, UT-Battelle to preserve centrifuge enrichment capabilities on interim basis

USEC and UT-Battelle have signed a $33.7 million, five-month contract to continue operating centrifuges and conducting research and development activities on a uranium enrichment project deemed important for national security and possible commercial use.

The agreement with UT-Battelle, which manages Oak Ridge National Laboratory, was signed May 1. The five-month term ends Sept. 30. The new agreement includes options for two six-month extensions valued at about $41.7 million each. The total price of the contract with the options is roughly $117 million.

USEC, which is now an ORNL subcontractor, previously performed research, development, and demonstration work on the project, the American Centrifuge Project, under an agreement with the U.S. Department of Energy that had been in place since June 12, 2012. That cost-sharing agreement expired April 30. [Read more…]

‘Atomic switcheroo’ explains origins of thin-film solar cell mystery

Treating cadmium-telluride (CdTe) solar cell materials with cadmium-chloride improves their efficiency, but researchers have not fully understood why. Now, an atomic-scale examination of the thin-film solar cells led by Oak Ridge National Laboratory has answered this decades-long debate about the materials’ photovoltaic efficiency increase after treatment.

A research team from ORNL, the University of Toledo, and the U.S. Department of Energy’s National Renewable Energy Laboratory used electron microscopy and computational simulations to explore the physical origins of the unexplained treatment process. The results are published in Physical Review Letters, or PRL.

Thin-film CdTe solar cells are considered a potential rival to silicon-based photovoltaic systems because of their theoretically low cost per power output and ease of fabrication. Their comparatively low historical efficiency in converting sunlight into energy, however, has limited the technology’s widespread use, especially for home systems. [Read more…]

UT-Battelle is contributing $10,000 in matching donations to a Habitat for Humanity project dedicated to Tim and Teresa Myrick, who have been enduring supporters of the organization that provides shelter for deserving families.

Tim Myrick’s handiwork dots the Oak Ridge landscape. He was a major contributor to the modernization campaign at Oak Ridge National Laboratory that resulted in a sparkling new east campus. He helped lead the renovation of the town’s high school.

He’s been involved in all the Anderson County Habitat for Humanity projects in some way—58 in all.

He wants to add to that tally. There is some urgency in the matter.

“With the cancer thing I set priorities: fighting cancer, the Habitat project, Living Waters, building a new church, doing some fly fishing,” he said. [Read more…]

Energy Department report finds major potential to increase clean, sustainable U.S. hydropower

WASHINGTON, D.C.—The U.S. Department of Energy and Oak Ridge National Laboratory on Tuesday released a renewable energy resource assessment detailing the potential to develop new electric power generation in waterways across the United States. The report estimates that there are more than 65 gigawatts (GW) of potential new hydropower development across more than three million U.S. rivers and streams. That’s nearly equivalent to the current U.S. hydropower capacity, a press release said.

The release said the findings demonstrate one of the ways the United States can further diversify its energy portfolio with sustainable and clean domestic power generation.

“The United States has tremendous untapped clean energy resources and responsible development will help pave the way to a cleaner, more sustainable and diverse energy portfolio,” Energy Secretary Ernest Moniz said. “As the Energy Department works with industry, universities, and state and local governments to advance innovative hydropower technologies, the resource assessment released today provides unparalleled insight into new hydropower opportunities throughout the country.” [Read more…]

KNOXVILLE—Federal officials have expressed concerns about increasing cost projections and delayed construction dates for a new Uranium Processing Facility at the Y-12 National Security Complex, and a so-called Red Team has drafted an alternative approach that could keep the project at $6.5 billion or less—and help workers get out of the aging Building 9212 at Y-12 by 2025.

Thom Mason, the director of Oak Ridge National Laboratory, chaired the Red Team, and he is expected to brief federal officials in Washington, D.C., today (Monday) on the team’s report. The report will then go to Congress, Energy Secretary Ernest Moniz said in a media briefing at the Howard H. Baker Jr. Center at the University of Tennessee on Friday.

Among the questions that could be answered are which old production buildings at Y-12 should be replaced and which can be refurbished. Y-12 was built to enrich uranium as part of the top-secret Manhattan Project during World War II as the United States raced to beat Germany to build the world’s first atomic weapons. [Read more…]

The topic for the 11th annual Jackson B. Davidson Memorial Lecture on Science and Religion will be “A Dwelling Place for God: Recovering the Forgotten Story of God, Humankind, Temple, and Creation.”

Stanley Saunders, associate professor of New Testament at Columbia Theological Seminary in Decatur, Ga., will deliver the lecture at 7 p.m. Sunday, April 27, in the sanctuary of First Presbyterian Church, 1051 Oak Ridge Turnpike (at Lafayette Drive).

Refreshments will be served after the lecture, and childcare will be provided during and after the free talk.

“Modern, western Christians typically presume that Christian salvation entails escape from our bodies and this earth, so that we can dwell with God in an ethereal heavenly realm,” Saunders said. “The New Testament, on the other hand, much more clearly affirms a vision of God coming to dwell with us.” [Read more…]
