WASHINGTON, D.C.— President Barack Obama recently announced plans to nominate two people to top U.S. Department of Energy posts, including a director of the Office of Science.

The Office of Science is responsible for 10 of the 17 DOE labs, including Oak Ridge National Laboratory.

Obama nominated Marc Kastner to serve as director of the Office of Science and Franklin Orr to serve as DOE under secretary for science and energy.

“I am confident that these outstanding individuals will greatly serve the American people in their new roles, and I look forward to working with them in the months and years to come,” Obama said in a press release.

Here is more information about the two candidates: [Read more…]

NNSA removes high-activity radioactive materials from Boston

WASHINGTON, D.C.—The National Nuclear Security Administration recently successfully recovered a disused, high-activity cesium-137 source from Massachusetts General Hospital in downtown Boston and transported it for permanent disposition. Formerly used as a research irradiator for medical studies, the device contained cesium-137, which could be used in a dirty bomb. The removal was part of NNSA’s global campaign to prevent terrorists from acquiring nuclear and radiological material.

“This operation is a key part of the NNSA’s broad strategy to strengthen both U.S. and global security by keeping dangerous nuclear and radiological material safe and secure,” said NNSA Deputy Administrator for Defense Nuclear Nonproliferation Anne Harrington. “Today’s announcement is a good example of how NNSA utilizes its unique expertise and assets at the national laboratories to partner with local communities and other agencies to make our cities and those around the world safer and more secure.” [Read more…]

CHARLOTTE, N.C.—The bidding team led by the Babcock and Wilcox Co. has filed a third protest over the contract to manage and operate the Y-12 National Security Complex in Oak Ridge and the Pantex Plant near Amarillo, Texas.

B&W announced the protest by the bidding team, Nuclear Production Partners LLC, or NP2, on Wednesday night. It was filed with the U.S. Government Accountability Office.

“This protest encompasses concerns identified in NP2’s June 17, 2013, protest of the revised Request for Proposals,” a B&W press release said. “The protest also reflects information received during the National Nuclear Security Administration’s debriefing session held on November 15.”

The June protest was the second filed by NP2, of Lynchburg, Va. The company had also filed one after the National Nuclear Security Administration announced in January that it had selected Consolidated Nuclear Security LLC of Reston, Va., to manage the two nuclear weapons plants. [Read more…]

UT professor receives more than $880,000 in DOE funding for carbon cycle research

UT Students Measure Soil Carbon Flux

KNOXVILLE—Carbon dioxide is key to life on Earth, but too much of the good thing can overheat the Earth’s surface and hurt the very things it supports. Thus, understanding how carbon cycles through the atmosphere is crucial to predicting its effects.

A University of Tennessee professor in Knoxville has received more than $880,000 from the U.S. Department of Energy to investigate often-overlooked carbon cycle players.

Aimee Classen, associate professor of ecology and evolutionary biology, and her team, which includes Oak Ridge National Laboratory staff members, will examine factors that influence carbon cycling below the ground and are not included in today’s carbon-cycle models.

“We know that tiny things that live in soil, like fungi, can regulate carbon processes in forests. However, our current soil models don’t consider what role fungal and plant root activity may play in soil carbon dynamics. Our project aims to fill this knowledge gap,” Classen said. [Read more…]

The U.S. Department of Energy’s Office of Science announced 59 projects, promising to accelerate scientific discovery and innovation, that will share nearly six billion core hours on two of America’s fastest supercomputers dedicated to open science. Their work will advance knowledge in critical areas from sustainable energy technologies to the environmental consequences of energy use.

The allocations come from the Innovative and Novel Computational Impact on Theory and Experiment, or INCITE, program. Through it, the world’s most advanced computational research projects from academia, government, and industry are given access to DOE’s leadership computing facilities at Oak Ridge and Argonne national laboratories.

Demolition of the last standing section of the K-25 Building at the East Tennessee Technology Park is more than 75 percent complete.

UCOR workers began tearing down the last six units in the east wing of the mile-long Manhattan Project-era gaseous diffusion building in September. The majority of those six units—4.5 of them—are already on the ground, and work is continuing at a steady pace, the U.S. Department of Energy Oak Ridge Office reported in the December issue of Public Involvement News.

The entire project, including waste removal, should be completed next year, the Oak Ridge Office said.

The historic, U-shaped K-25 Building was erected to enrich uranium for atomic bombs during World War II, and it was once the world’s largest building under one roof. It once had 54 units. [Read more…]

UCOR has finished installing permanent electrical equipment at the 3026 hot cells facility at Oak Ridge National Laboratory.

This action completes all scheduled tasks under the 3026 Hot Cells Transition and Stabilization Phase, the U.S. Department of Energy Oak Ridge Office reported in the December issue of Public Involvement News.

UCOR took over the 3026 Hot Cells project at the request of DOE. The stabilization activities were con- ducted to help “downgrade” the facility from a Hazard Category 3 nuclear facility to a radiological facility, the Oak Ridge Office said. This downgrade, which has been approved by DOE, will make the facility less costly to maintain.

UCOR is DOE’s cleanup contractor in Oak Ridge.

A Chinese supercomputer kept its top ranking, and Titan at Oak Ridge National Laboratory stayed at No. 2 in a Top 500 ranking of the world’s most powerful supercomputers released Monday morning.

The top two spots were unchanged from the semiannual rankings released five months ago in June, when Tianhe-2, a supercomputer developed by China’s National University of Defense Technology, bumped Titan from the top spot. The ORNL supercomputer had been named No. 1 one year ago.

The rankings released Monday at the SC13 conference in Denver, Colo., said Tianhe-2 is capable of performing 33.86 petaflops. That’s 33.86 quadrillion calculations per second, on what is known as a Linpack benchmark test.

Titan is a Cray XK7 system that achieved 17.59 petaflops. Titan is one of the most energy-efficient systems on the list, consuming a total of 8.21 megawatts and delivering 2.143 gigaflops per watt, a press release said. [Read more…]

Ernest Shepherd attended the Veterans Day ceremony on Monday at Oak Ridge National Laboratory wearing a uniform similar to what he wore in 1944 when the hospital he was working in as a medic in Belgium was hit with a German bomb.

Shepherd—89 years old and an ORNL retiree who treated wounded from the D-Day invasion prior to moving on to Belgium—would earn the Purple Heart for his heroics in the aftermath of the bombing.

“It blew out all the windows in that whole building,” recalled Shepherd, who was on the second floor when the bomb crashed into the hospital and exploded about 300 feet from where he was located. “It killed 29 people. There were between 12 to 15 air personnel killed, and one major who I really liked got killed. I got wounded in the face with shrapnel or flying glass. That’s how I earned the Purple Heart.” [Read more…]

A retired distinguished staff member at Oak Ridge National Laboratory will discuss Thursday evening whether small modular nuclear reactors, such as the one proposed in west Oak Ridge, can rejuvenate nuclear power.

The presentation by Kent Williams starts at 7 p.m. Thursday in the Fellowship Hall at First Presbyterian Church in Oak Ridge.

Many people in the nuclear industry say that small modular reactors, or SMRs, are key to a revitalized nuclear industry in the U.S. and overseas because of their projected market, safety, and economic characteristics, a press release said. One SMR plant has been proposed at the former Clinch River Breeder Reactor site in west Oak Ridge. [Read more…]
