The Oak Ridge City Council on Monday night will consider adding a facilities charge to the U.S. Department of Energy’s monthly wastewater bill for costs related to the construction of a holding tank, or equalization basin, near the Y-12 National Security Complex.

The equalization basin on Scarboro Lane, near the intersection of Scarboro Road and South Illinois Avenue, will service wastewater coming out of the federal reservation, city officials said. Wastewater flows from DOE facilities are estimated to be 67 percent of the total wastewater flow coming into that equalization basin, which will replace a now-demolished car wash near the intersection.

Assuming a 67 percent-33 percent split between DOE and the city, DOE’s share of the cost for construction of the Scarboro Lane equalization basin is estimated at $1.4 million, city officials said. DOE could pay another $24,190 per month as part of its wastewater bill for 60 months starting in July, Oak Ridge Finance Director Janice E. McGinnis said. [Read more…]

WASHINGTON, D.C.—The National Nuclear Security Administration on Thursday marked the 10th anniversary of the Global Threat Reduction Initiative, GTRI. Since the Sept. 11 attacks, reducing the threat of terrorist acquisition of nuclear or radiological material has been a core mission of NNSA, and it is a mission that will continue into the future.

“The Global Threat Reduction Initiative’s history demonstrates how seriously we take this mission and our commitment to fulfilling President Obama’s nuclear security agenda,” said U.S. Department of Energy Under Secretary for Nuclear Security and NNSA Administrator Frank G. Klotz. “However, the threat to national and global security from state or terrorist acquisition of nuclear and radiological materials is far from gone, and our focus now is on addressing the substantial threats that remain.”

GTRI, an NNSA nuclear nonproliferation program, works with partners around the world to reduce and consolidate global stockpiles of highly enriched uranium, or HEU, and plutonium, and to secure dangerous radiological sources both at home and abroad. GTRI and its predecessor programs have removed and secured more than enough material for 980 nuclear weapons and tens of thousands of radiological dirty bombs by converting HEU research reactors and isotope production facilities to the use of low enriched uranium, or LEU; removing or confirming disposition of HEU and plutonium; and securing nuclear and radiological sites around the world.

A simple new technique to form interlocking beads of water in ambient conditions could prove valuable for applications in biological sensing, membrane research, and harvesting water from fog.

Researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory have developed a method to create air-stable water droplet networks known as droplet interface bilayers. These interconnected water droplets have many roles in biological research because their interfaces simulate cell membranes. Cumbersome fabrication methods, however, have limited their use.

“The way they’ve been made since their inception is that two water droplets are formed in an oil bath then brought together while they’re submerged in oil,” said ORNL’s Pat Collier, who led the team’s study published in the Proceedings of the National Academy of Sciences. “Otherwise they would just pop like soap bubbles.”

Instead of injecting water droplets into an oil bath, the ORNL research team experimented with placing the droplets on a superhydrophobic surface infused with a coating of oil. The droplets aligned side by side without merging. [Read more…]

The Oak Ridge Site Specific Advisory Board and the U.S. Department of Energy’s Oak Ridge Office recognized outgoing student representatives Gracie Hall and Julia Riley at the April board meeting.

ORSSAB is a federally chartered citizens’ panel that provides recommendations to the DOE Oak Ridge Environmental Management Program, which is responsible for the cleanup of the Oak Ridge Reservation. Each year it provides seats for two non-voting student representatives from area high schools. In addition to participating at board meetings, students can be members of the board’s working committees.

“We appreciate the insight the student representatives provide during their tenure on the ORSSAB, so it’s always sad to see them leave when they complete their terms,” said Susan Cange, deputy assistant manager for the DOE Oak Ridge Environmental Management Program and the board’s deputy designated federal officer. “We are thankful to them for dedicating time during their busy senior year of high school to help provide valuable input in support of environmental cleanup in Oak Ridge.”

Gracie will graduate from Oak Ridge High School in May. For the last couple of years, she has been training in martial arts and has a blue-purple belt in Filkenjutsu. She plans to continue training and teaching various forms of martial arts.

Gracie also likes to sing and will be singing in her last Sound Company show in May. Sound Company is a local group of young singers and dancers.

She will be attending the University of Tennessee Knoxville this fall in the honors program with an undeclared major. She is considering environmental science or criminal justice. She does plan to minor in Spanish.

Julia will graduate from Hardin Valley Academy in May. During her senior year, she has been active as president of Hardin Valley’s Venture Crew. She has been involved in blood drives at Hardin Valley as assistant to one of her teachers who coordinates the drives.

Julia will attend Clemson University this fall in the honors program studying environmental science with a wildlife biology minor.

Two new students from Oak Ridge High School and Hardin Valley Academy will be seated in May.

CHATTANOOGA—Retired Lt. Gen. Frank G. Klotz, the recently confirmed undersecretary for nuclear security for the U.S. Department of Energy and administrator of the National Nuclear Security Administration, will be a keynote speaker at the Tennessee Valley Corridor Summit in June. Along with University of Tennessee President Joe DiPetro, Klotz will speak at the event’s Leadership Luncheon, which will conclude the June 4-5 event on the campus of the University of Tennessee at Chattanooga.

Klotz was confirmed by the U.S. Senate in April to lead the NNSA in its mission to improve national secruity through the military application of nuclear energy. NNSA maintains the nation’s nuclear weapons stockpile and is responsible for many nuclear nonproliferation, counter-terrorism, and radiological emergency response efforts for the United States as well as providing fuel for the country’s nuclear Navy. The Y-12 National Secruity Complex in Oak Ridge is one of NNSA’s most important facilities.

“Gen. Klotz occupies one of the most important jobs in the federal government to assure a strong nuclear deterrence for our nation’s security and the safety of our nuclear stockpile,” said Gerald Boyd, TVC board chair and former DOE Oak Ridge site manager. “It’s a great honor for the TVC to host one of his first public addresses as the new DOE undersecretary and NNSA administrator.” [Read more…]

But hundreds of jobs maintained in Ohio and Tennessee, USEC says

Babcock and Wilcox has terminated the employment of more than 100 workers who had been involved in the American Centrifuge project with USEC, and Monday was the last day of work for most of them, a spokesperson said.

“B&W’s involvement in the American Centrifuge Manufacturing LLC has transitioned fully to USEC, which will result in the termination of all 122 employees B&W had engaged in the effort,” said Aimee Mills, B&W media relations lead.

Mills said roughly 25 employees will be released during the next two months as the “final steps of demobilization take place” on the advanced uranium enrichment project, which has included centrifuge manufacturing in Oak Ridge and the American Centrifuge Plant in Piketon, Ohio.

“Some of those affected have been reassigned within B&W,” Mills said. “We have also provided assistance by way of job fairs and workshops to update resumes.”

Meanwhile, USEC has notified a small group of its Oak Ridge employees who worked on manufacturing activities that they would be laid off, Communications Manager Jeremy Derryberry said Tuesday. Several were transferred to other parts of the centrifuge program. [Read more…]

The University of Tennessee donated the Living Light House to the Children’s Museum of Oak Ridge, and the 750-square-foot solar-powered home was moved Saturday.

 

The University of Tennessee in Knoxville has donated its Living Light House to the Children’s Museum of Oak Ridge, and the 750-square-foot solar-powered home was moved Saturday.

The award-winning home makes more energy than it uses, said James Rose, senior lecturer in UT’s College of Architecture and Design.

Moving the 80,000-pound house was a daylong project. The Children’s Museum is in a residential area in Oak Ridge, so the museum had to move trees, excavate a slope, and create a temporary road to get to the site.

Rose said the one-room home, which has mechanical and laundry areas, will be used at the Children’s Museum for outreach and to showcase the latest energy-efficient technologies.

“This is the perfect place for this building,” said Rose, the architect of record on the project and the leader of the student architecture studio that designed it. [Read more…]
