Friends of Oak Ridge National Laboratory will have its third talk on the U.S. ITER project on Tuesday. ITER is the International Thermonuclear Experimental Reactor, and it will be constructed at Cadarache, France, and is expected to be completed within 10 years.

The Friends of ORNL lecture starts at noon Tuesday at the University of Tennessee Resource Center. It will feature Graeme Murdoch, who will discuss U.S. ITER non-nuclear systems.

“The United States has joined with China, the European Union, India, Japan, Korea, and Russia to construct and operate ITER, a full-scale, 500 megawatt experimental fusion device,” a press release said. “U.S. Contributions to ITER include hardware (with supporting research and development and design), personnel (U.S. engineers and scientists) to the ITER site in Cadarache, and cash contributions to the ITER organization. US-supplied hardware includes magnets, blankets, diagnostics, tritium processing, ion cyclotron and electron cyclotron heating and current drive systems, pellet fueling, and more conventional systems such as cooling water and electrical power systems.”

ITER is a large-scale project that presents many engineering challenges, the press release said. [Read more…]

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…]

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…]

Splitting UPF project into two buildings could save money, senator says

Money could be saved on the new Uranium Processing Facility at the Y-12 National Security Complex by splitting up the project into two buildings rather than one, U.S. Sen. Lamar Alexander said during a congressional hearing in Washington, D.C., on Wednesday.

One building could be used for high-security work, Alexander said during a hearing of the Energy and Water Development Subcommittee. That high-security building would cost several times as much as a second building used for low-security work, Alexander said.

Not all of the work has to be conducted in a high-security facility, the Tennessee Republican said, and some of it could be conducted in the low-security building.

It wasn’t immediately clear if the two-building proposal is included in a so-called Red Team Review of the UPF project. That report could be made public this week. Federal officials and members of Congress have already been briefed on it. [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…]

ORNL equipment weighing 1,500 pounds falls on worker’s legs

A piece of surplus equipment that weighs more than 1,500 pounds tipped over and fell onto the legs of an Oak Ridge National Laboratory worker on March 31, fracturing both legs and breaking his thumb, a spokesman said.

When it tipped over, a few ORNL employees were loading the scattering chamber and cart onto the box truck of a person who had purchased the equipment at an auction, said David Keim, ORNL communications director.

A few metal arms that protrude from the scattering chamber might have hit the floor of the truck and created some space between the “deceptively heavy” piece of equipment and the worker’s legs, preventing even more serious injuries, Keim said. Also, the chamber and cart might have hit other equipment already loaded into the back of the truck, also helping to prevent more serious injuries. [Read more…]
