A pavement collapse at Oak Ridge National Laboratory in early June was a significant distance from an area where uranium-233 is stored at Building 3019, the U.S. Department of Energy said Monday.

The collapse of about 36 square feet of pavement was near Building 3019B, which is an inactive facility, the DOE Oak Ridge Office of Environmental Management said.

The hot cells in the facility were not affected, and they do not contain radioactive material, DOE said.

“There were no immediate safety hazards to personnel, but as a precaution, the area was barricaded until crews made repairs,” DOE said.

Uranium-233, or U-233, is a fissionable material, and Building 3019 area is a secure and controlled area. The pavement collapse was reported by the Defense Nuclear Facilities Safety Board on June 19. [Read more…]

COHERENT’s cesium iodide detector, the first to espy neutrinos at the SNS, employs a 5-inch (13-centimeter) wide photomultiplier tube. An 8-inch (20-centimeter) wide photomultiplier (shown here) is deployed in COHERENT’s nearby liquid-argon detector.

After more than a year of operation at Oak Ridge National Laboratory, the COHERENT experiment, using the world’s smallest neutrino detector, has found a big fingerprint of the elusive, electrically neutral particles that interact only weakly with matter.

The research, performed at ORNL’s Spallation Neutron Source and published in the journal Science, provides compelling evidence for a neutrino interaction process predicted by theorists 43 years ago but never seen.

“The one-of-a-kind particle physics experiment at Oak Ridge National Laboratory was the first to measure coherent scattering of low-energy neutrinos off nuclei,” said ORNL physicist Jason Newby, technical coordinator and one of 11 ORNL participants in COHERENT, a collaboration of 80 researchers from 19 institutions and four nations.

The SNS produces neutrons for scientific research and also generates a high flux of neutrinos as a byproduct. Placing the detector at SNS a mere 65 feet (20 meters) from the neutrino source vastly improved the chances of interactions and allowed the researchers to decrease the detector’s weight to just 32 pounds (14.5 kilograms). In comparison, most neutrino detectors weigh thousands of tons: although they are continuously exposed to solar, terrestrial, and atmospheric neutrinos, they need to be massive because the interaction odds are more than 100 times lower than at SNS.

The scientists are the first to detect and characterize coherent elastic scattering of neutrinos off nuclei. This long-sought confirmation, predicted in the particle physics Standard Model, measures the process with enough precision to establish constraints on alternative theoretical models. [Read more…]

CH2M, which is part of UCOR, the federal cleanup contractor in Oak Ridge, is being acquired by Jacobs Engineering Group Inc.

The acquisition was announced Wednesday. It’s a a cash-and-stock transaction of about $3.27 billion, including a $2.85 billion purchase and roughly $416 million of CH2M net debt. It’s expected to close in the first quarter of Jacobs’ fiscal year 2018, which ends at the end of 2017.

The two companies are separate until then.

It’s too early to say whether the acquisition would have any effect on the federal contract with UCOR, but the companies said the transaction is about growth, acquiring the expertise of CH2M, and expanding the presence of the combined company.

A Knoxville man was indicted last month on robbery, kidnapping, and conspiracy charges for his role in an alleged robbery at gunpoint in Claxton in 2016 that authorities said started with an advertisement for escort services posted on backpage.com.

Richard Pressley, 31, has been indicted on charges of aggravated robbery, especially aggravated kidnapping using a weapon, conspiracy to commit aggravated robbery, and conspiracy to commit especially aggravated kidnapping. He was indicted by the Anderson County Grand Jury on July 11.

The alleged robbery and kidnapping occurred in a mobile home on Queen Street in Ben’s Mobile Home Park off Edgemoor Road in Claxton on May 21, 2016, the Anderson County Sheriff’s Department said in a press release after Pressley and his wife, Lindsay Pressley, were arrested last year.

Affidavits filed in Anderson County General Sessions Court in Clinton on May 23, 2016, said the alleged victim, Cody Monroe, traveled from Athens to the address provided in the backpage.com ad. Monroe “made small talk” with the female, later identified as Lindsay Pressley, for about five minutes when a man brandishing a handgun, later identified as Richard Pressley, entered the living room and ordered Monroe onto the ground, according to the affidavits.

James Peery, who has led critical national security programs at Sandia National Laboratories and Los Alamos National Laboratory, has been selected as the chief scientist of the Global Security Directorate at Oak Ridge National Laboratory.

“James brings more than two decades of experience in creating successful national security initiatives for the U.S. Department of Energy,” said Brent Park, associate laboratory director of global security at ORNL. “In particular, his leadership in cybersecurity, data analytics, and high-performance computing will enable him to lead the laboratory’s cybersecurity initiative for the electric grid and beyond.”

Next-generation cybersecurity for the electric grid is a multi-directorate, multi-program effort at ORNL that supports the DOE cybersecurity program for critical energy infrastructure, a press release said. The initiative aims to enable electric utilities and other components of the nation’s energy supply to defend against emerging and previously unseen cyberattacks.

Peery also will help ORNL researchers draw on the lab’s distinctive capabilities to develop scientific and technological solutions aligned with national security policies and strategies, the press release said. [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 Schools will transport students and provide eclipse glasses for the solar eclipse on Monday, August 21. It will be a once-in-a-lifetime experience for many people.

The path of totality for the solar eclipse cuts through Oak Ridge, according to information provided to the Oak Ridge Board of Education for a meeting on Monday, August 7.

Because the path of totality cuts through Oak Ridge, half of the city’s schools are in the path of totality and half are not, the information said.

“We believe that every Oak Ridge student should have the opportunity to learn about the eclipse and to experience the total eclipse,” the information said. “Therefore, we will be transporting students from the east side of Oak Ridge to the west side, with parental permission.”

The solar eclipse of 2017 is a once-in-a-lifetime experience for many people, the information said. [Read more…]
