The ability to control nanoscale imperfections in superconducting wires results in materials with unparalleled and customized performance, according to a new study from the U.S. Department of Energy’s Oak Ridge National Laboratory.

Applications for superconducting wires, which carry electricity without resistance when cooled to a critical temperature, include underground transmission cables, transformers, and large-scale motors and generators. But these applications require wires to operate under different temperature and magnetic field regimes. [Read more…]

Better batteries, catalysts, electronic information storage and processing devices are among potential benefits of an unexpected discovery made by Oak Ridge National Laboratory scientists using samples isolated from the atmosphere.

Researchers at the U.S. Department of Energy lab learned that key surface properties of complex oxide films are unaffected by reduced levels of oxygen during fabrication—an unanticipated finding with possible implications for the design of functional complex oxides used in a variety of consumer products, said Zheng Gai, a member of DOE’s Center for Nanoscale Materials Sciences at ORNL.

The findings are detailed in a paper published in Nanoscale. [Read more…]

Leo Sain at K-25

Leo Sain, president and project manager for cleanup contractor UCOR, near the east wing of the mostly demolished K-25 Building, built to enrich uranium during World War II and also used during the Cold War.

It’s been two years since UCOR, the federal government’s cleanup contractor in Oak Ridge, started working in the Secret City.

UCOR president Leo Sain celebrated with an Aug. 1 letter to employees that thanked them but also issued a reminder and challenge. Read the letter here.

Sain said he is very proud of the workforce—he called the company’s performance spectacular—and said work has been done safely, under budget, and ahead of schedule.

“At the end of two years, we’re one of the safest sites in the U.S. Department of Energy complex,” Sain said. “The credit for that goes entirely to you, the workforce, for staying focused on your work through all the distractions and changing hazards that come with the tasks we perform.” [Read more…]

Note: This is an edited copy of a letter that UCOR President Leo Sain sent to company employees on Aug. 1.

To All UCOR Employees:

As we begin our third year on the job here at East Tennessee Technology Park, I want to thank everyone for an outstanding two years.

I am so very proud of this workforce. Our performance has been truly spectacular in every way. K-25, one of our nation’s largest deactivation and decommissioning projects, is nearly on the ground, and we’ve begun pre-demolition work in K-27 significantly ahead of schedule. We’ve disposed of over 120,000 cubic yards of waste while safely traveling over 1.5 million miles. [Read more…]

The public bus tours of the U.S. Department of Energy’s Oak Ridge facilities end Aug. 30. It’s the last day of the 2013 season.

The tours include stops at Oak Ridge National Laboratory, Y-12 National Security Complex, and East Tennessee Technology Park, and they provide historical commentary on the transformation of the Oak Ridge Reservation during the past 65 years.

So far this season, 1,148 visitors from 43 states have participated in the summer tour, a press release said. [Read more…]

The U.S. Department of Energy is preparing to “recompete” the contract to manage the Transuranic Waste Processing Center off Highway 95 in west Oak Ridge.

The facility is currently managed by a contractor, Wastren Advantage Inc., and the work is overseen by officials at DOE’s Oak Ridge Office.

DOE has issued a “sources sought notice” to begin performing market research to gauge whether there are small businesses capable of performing the work, the Oak Ridge Office said in the August issue of “Public Involvement News.” [Read more…]

The FBI is investigating a report of a man possibly trespassing at the East Tennessee Technology Park on Thursday evening, but so far, they said, it doesn’t appear he posed any danger to the former uranium-enriching site.

“I can tell you right now that there is no indication that this incident involves any kind of threat to the facility or to national security,” said Marshall Stone, supervisory special agent in the Knoxville office of the Federal Bureau of Investigation. [Read more…]

Old or unused laboratory equipment that has outlived its usefulness at Oak Ridge National Laboratory and other U.S. Department of Energy sites doesn’t have to sit idle or wind up in the scrap heap. In 2012, ORNL donated $1.7 million worth of surplus property to nonprofits, including local schools, where it is now helping to inspire future scientists.

DOE works with the state of Tennessee to enable the surplus government property to go to school science labs and nonprofit agencies that can make effective use of the equipment.

Local schools have received fume hoods, water baths, centrifuges, and tilt tables, as well as ultrasonic cleaners, balances, and a variety of expensive glassware. The donated tools, outdated at any national lab, are now treasures for high school students, allowing them to conduct STEM research with high quality materials at a reasonable cost. [Read more…]
