The Oak Ridge Tree Board is hosting a workshop focused on the impact of the emerald ash borer in the area. The event, scheduled for the evening of Tuesday, August 29, will provide important information regarding the emerald ash borer for property owners, landscapers, and others involved in the maintenance of green spaces, a press release said.

“Ash trees make up a significant percentage of our urban forest and have traditionally been a landscaping staple,” the press release said. “Many of these trees in Oak Ridge are already dead or beyond treatment, but a significant number can be saved. At the workshop later this month, experts from around the area will address issues such as identification of affected ash trees and responses to EAB (emerald ash borer) infestation, including appropriate treatment.”

Those who attend will learn about these pests and their origin and how they spread across the country, as well as the techniques used in diverse areas ranging from the Great Smoky Mountains National Park to urban areas, such as Knoxville and surrounding municipalities. [Read more…]

Researchers at federal sites such as Oak Ridge National Laboratory first developed many of the concepts and tools that ecologists still use today, according to the U.S. Department of Energy.

“The study of ecology is likely to evoke images of recycling signs or the ‘blue marble’ Earth from space associated with the environmental movement of the 1960s,” the U.S. Department of Energy Office of Science said in an article published online on June 28. “But in reality, ecology as a field largely developed to meet the need to monitor radioactive contamination in the Atomic Age.”

The federal government had a major knowledge gap after World War II, according to the article, which was written by Shannon Brescher Shea, senior writer/editor in DOE’s Office of Science. Specifically, the United States government needed to know more about the consequences of nuclear weapons use and production, from the effects of fallout to waste disposal.

The Atomic Energy Commission’s national laboratories were logical places to answer these questions, the article said. [Read more…]

The U.S. Navy teamed up with Oak Ridge National Laboratory to print the military’s first 3D-printed submersible hull in just four weeks. The parts were printed in just days, rather than weeks, and production costs were cut by 90 percent.

The hull was printed at ORNL’s Manufacturing Demonstration Facility in Hardin Valley through a partnership with the Navy’s Disruptive Technology Lab, according to a story published July 20 by the U.S. Department of Energy Office of Energy Efficiency and Renewable Energy. ORNL is a DOE laboratory.

“ORNL and the Navy saw this is as an opportunity to bring together their resources and expertise in a partnership with the potential to revolutionize manufacturing in the defense sector,” the DOE story said. “Not only can the Navy find new ways to reduce traditional costs associated with manufacturing, but the lessons learned from this project will help ORNL further explore 3D printing applications in the boating industry, aerospace, buildings, and anything that requires a large, resilient structure. Partnerships like these help drive economic growth and reinforce our national security.”

The team working on the 3D-printed submersible hull needed to create a 30-foot proof-of-concept hull out of carbon fiber composite material, DOE said. The prototype vessel is called the Optionally Manned Technology Demonstrator, and it could be used to deploy logistics capabilities and sensors. Future vessels will need to be manufactured faster and incorporate new designs to support Navy missions, DOE said. [Read more…]

Oak Ridge National Laboratory on Wednesday said it is building the world’s smartest supercomputer.

The new supercomputer is called Summit. It will be located in a new data center next to Titan, which is now the fourth most powerful supercomputer in the world.

Summit will be 5-10 times faster than Titan, ORNL said. It will move data five to 10 times faster, store eight times more data, and perform many more calculations simultaneously than Titan, the lab said in information provided by spokesperson Morgan McCorkle.

Summit will be the world’s smartest supercomputer because of its enormous memory and data handling capabilities as well as its unique machine learning processor design, McCorkle said.

“The first of Summit’s cabinets arrived Monday, and our team is in the process of uncrating and putting them in place,” McCorkle said in response to questions from Oak Ridge Today. [Read more…]

Note: This is an edited version of a story that was first published by the U.S. Department of Energy Office of Environmental Management in an EM Update on Friday, July 28.

Workers began demolishing the Poplar Creek facilities this month, bringing Oak Ridge’s environmental management, or EM, program closer to completing major cleanup at the East Tennessee Technology Park by 2020.

“Demolishing the Poplar Creek facilities is significant for our program because it continues the visible transformation of ETTP’s skyline, and it removes the most contaminated facilities remaining at the site,” said Jay Mullis, acting manager of the U.S. Department of Energy’s Oak Ridge Office of Environmental Management, or OREM.

OREM has taken down more than 400 facilities at ETTP, including all five former uranium enrichment facilities. That’s about 10 million square feet of buildings that have been removed.

ETTP, also known as Heritage Center, is the former K-25 site in west Oak Ridge. The site was built to help enrich uranium for atomic bombs during the top-secret Manhattan Project in World War II, and it continued to operate through the Cold War, including to enrich uranium for nuclear power plants.

Oak Ridge National Laboratory is pursuing two major upgrades to its Spallation Neutron Source that would allow new scientific research and could cost more than $1 billion.

The two proposed upgrades are a proton power upgrade and a second target station. The two projects are in different stages of review at the U.S. Department of Energy, ORNL spokesperson Morgan McCorkle said.

The proton power upgrade, or PPU, is being pursued first, and its current cost estimate is a little more than $200 million, McCorkle said. If approved, it would double the power of SNS’s proton beam from 1.4 megawatts to 2.8 megawatts.

The upgrade would allow new types of research at SNS, and it would increase the number of scientists who can use the facility each year, McCorkle said.

“The PPU will enable experiments that are not currently feasible, such as experiments on smaller or less concentrated samples, and experiments under more extreme environmental conditions,” McCorkle said. “The new scientific capabilities will support research in areas such as soft matter, quantum materials, chemistry, functional materials, and biology. Some examples of everyday products that may be improved by these discoveries include cell phones, batteries, computers, building materials, and drugs.”

The proton power upgrade would also eventually provide the extra power necessary for the proposed second target station, or STS. The design of the second target station is less mature, but the project could cost in the range of $1 billion and include about 300,000 square feet of new buildings, McCorkle said. The second target station would be on the east end of the SNS campus on Chestnut Ridge at ORNL.

Appropriations committees in both the U.S. Senate and House of Representatives have recommended funding for a project that could reduce the Protected Area at the Y-12 National Security Complex by about 50 percent.

The House Appropriations Committee approved an energy and water appropriations bill on Wednesday, July 12, that recommended $23.4 million for the project, the West End Protected Area Reduction project, in fiscal year 2018, which starts October 1. That would be up from $2.5 million in fiscal year 2017. (See page 135 here.) If approved, the House bill would direct the National Nuclear Security Administration to give quarterly project updates to the appropriations committees in both houses of Congress “until such time as the NNSA can demonstrate a commitment to move the project forward.” (See page 105 here.)

The Senate Appropriations Committee approved an energy and water appropriations bill on Thursday, July 20, that recommended $5 million in fiscal year 2018. (See page 119 here.) That money is recommended to continue the design work for the project, according to a report on the Senate bill. (See page 98 here.)

The Trump administration did not request any funding for the project, and it’s not clear what level of funding might eventually be approved. [Read more…]

The U.S. Department of Energy’s Office of Nuclear Energy has selected Lou Qualls of Oak Ridge National Laboratory as the national technical director for molten salt reactors, or MSRs. In his new role, Qualls—a nuclear engineer who joined ORNL in 1988—will serve as a liaison among the nuclear industry, the national laboratory system, and DOE in defining the future of MSR technology in the United States.

The new position was created in response to the private sector’s growing interest in MSRs as the next generation of power reactors. A significant number of nuclear plants are expected to close beginning in 2030, with most closed by 2045, as their operating licenses from the Nuclear Regulatory Commission expire. Various companies are pursuing new reactor designs to replace this loss of nuclear energy, which is the nation’s largest source of carbon-free energy and represents approximately one-fifth of electricity generated in the United States.

“There are about 10 U.S. companies developing MSR designs in hopes of seeing their technologies make it onto the grid,” Qualls said. “My job is to work with these vendors and DOE to understand how each design could fit into the energy market and to identify hurdles that could prevent these reactors from ever delivering electricity. It’s a positive step that shows the level of excitement from industry, DOE, and the national labs.” [Read more…]

The Trump administration and congressional appropriations committees have agreed that $28 million in federal funding should be provided for a new fire station at the Y-12 National Security Complex.

The current fire station at Y-12 was built in the 1940s, and it is located within the most highly protected area of the nuclear weapons plant and close to the most hazardous operations, according to the National Nuclear Security Administration. Y-12 is an NNSA site.

“Seismic, tornado, hazardous material release, and security events could render the fire station inaccessible,” the NNSA said in a budget request submitted to Congress for fiscal year 2018, which starts October 1. (See page 271 here.)

Emergency planning assessments show that many hazardous materials releases would “have a very short travel time” before affecting the fire station, the NNSA said. Also, it’s critical to allow off-duty personnel to access the fire station since they augment the on-duty staff, the NNSA said.

The new fire station would be a single-story building of about 35,000 square feet. It would be located on the east end of Y-12, said Steven Wyatt, spokesperson for the NNSA Production Office in Oak Ridge. [Read more…]

Inventors at the Y-12 National Security Complex were awarded honors for their innovative technology accomplishments during the recent 13th annual Technology Transfer Awards Ceremony. The site has a long history of producing technologies that are transferred to the private sector, Y-12 said in a story posted on its website in June.

Ten patents were awarded in fiscal year 2016 in areas ranging from an apparatus for characterizing aerosols to several unique material processes, Y-12 said.

Thirty-three inventors also were recognized for bringing forward new ideas in the form of invention disclosures that could one day lead to future patents.

“These employees were acknowledged for both their creativity and innovative ideas in support of the technology development and transfer mission,” the story said. “The new inventions developed by the honorees will be used to further Y-12’s mission work and will be made available through license to benefit the public through Y-12’s Technology Transfer program.” [Read more…]
