Oak Ridge National Laboratory is developing a probe to accurately detect direct current, or DC, energy in electric vehicles and rooftops with solar panels. That is expected to help ensure the safety of first responders and electrical workers.

“With more volts than ever before in electric vehicles and on solar-paneled rooftops, first responder and electrical worker safety is a growing concern,” ORNL said in a story published on its website on Monday. “Researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory are addressing the challenge with the development of a probe to accurately detect direct-current energy.”

The DC “Hot Stick” probe is designed under the sponsorship of the U.S. Fire Administration, a division of the U.S. Department of Homeland Security. Not only does the DC “Hot Stick” detect DC voltage, but it also ensures that the probe is properly tapped into the electrical lines being tested, said the story, written by Stephanie G. Seay.

“The latter is essential because false negatives may be obtained if a meter is not making proper contact, noted ORNL lead scientist Bruce Warmack of the Electrical and Electronics Systems Research Division. [Read more…]

For the first time since 2012, transuranic waste processed and treated in Oak Ridge is leaving the Transuranic Waste Processing Center for permanent disposal at the Waste Isolation Pilot Plant near Carlsbad, New Mexico.

The first shipment left Oak Ridge on August 9.

Transuranic waste consists of materials and debris that are contaminated with elements that have a higher atomic mass and listed after uranium on the periodic table. The majority of Oak Ridge’s inventory originated from previous research and isotope production missions at the Oak Ridge National Laboratory.

“Resuming shipments has been an important priority for our program due to the large inventory of processed waste that is stored in onsite facilities,” said Jay Mullis, acting manager of the U.S. Department of Energy’s Oak Ridge Office of Environmental Management. “These shipments will remove risk from our site and help fulfill our commitments to the state of Tennessee. This was only possible through a lot of hard work from the federal and contractor employees here and support from staff in Carlsbad.”

Originally, much of the site’s transuranic waste was scheduled for shipment in 2014. However, weeks before shipments started, two events occurred at WIPP in February 2014—a truck fire and an unrelated radiological event—that suspended waste disposal operations, a press release said. These operations resumed in January 2017, and WIPP has begun receiving shipments from select sites across the U.S. Department of Energy complex.

A rezoning being considered by Oak Ridge municipal officials could allow commercial development on property that is now mostly a grass field south of the American Museum of Science and Energy. The 7.44-acre site could be used by retailers, restaurants, or groceries, or for office space or multi-family developments, according to a zoning change request filed by the owner.

The Oak Ridge Municipal Planning Commission will consider the rezoning request on Thursday. The request was filed by TN Oak Ridge Illinois LLC of Greenville, South Carolina. That company was set up by RealtyLink, the developer of Main Street Oak Ridge at the former Oak Ridge Mall.

The property includes a grass field along South Illinois Avenue between South Tulane Avenue and Badger Avenue. The northern portion of the property includes part of the AMSE parking lot.

The parcel, appraised at $908,300, is located within the city’s central commercial core, the Oak Ridge city staff said in a review of the rezoning request. There are commercial properties on the opposite side of South Tulane Avenue, including the Main Street Oak Ridge redevelopment, the staff said. There is also commercial development on the other side of South Illinois Avenue. [Read more…]

The workforce reduction of up to 350 positions at Oak Ridge National Laboratory is expected to decrease personnel costs by about $34 million each year, and the lab expects most of those who apply for voluntary separations from the lab to be of retirement age, a spokesperson said Wednesday.

The workforce reduction, which is expected to be completed by the end of this year, was announced by new ORNL Director Thomas Zacharia in a Tuesday morning email to employees.

“From time to time, sustaining our work effectively and efficiently requires the most difficult of decisions, which is to reduce our staff in certain areas of the lab,” Zacharia said in that email.

The lab hopes to reduce its workforce of 4,800 employees by about 7.3 percent (350 positions) using voluntary separations. Involuntary separations will be used if necessary.

On Wednesday, ORNL spokesperson Morgan McCorkle said the lab plans to reduce about 250 overhead positions and 100 research and development jobs. Overhead jobs are those not directly related to research. The research and development staff who will be eligible for voluntary separations are those who charge more than half of their time to overhead accounts or whose program budgets were reduced in fiscal year 2017, McCorkle said.

A specific breakdown of the affected jobs is not yet available. [Read more…]

Oak Ridge wants to renovate the fire station where the federal government and its contractors are building the K-25 History Center, a project that is expected to help preserve the history of the World War II-era Manhattan Project.

The K-25 History Center will be built on the second floor of Oak Ridge’s Fire Station Number 4. The fire station is at East Tennessee Technology Park, the former K-25 site in west Oak Ridge.

K-25 was one of three major federal sites built in Oak Ridge during World War II as part of the top-secret Manhattan Project. That was a federal program to build the world’s first atomic weapons, before Germany could.

K-25’s signature facility, the K-25 Building, has been demolished. But a 2012 agreement that allowed the complete demolition of that building, once the world’s largest building under one roof, called for the history center at the fire station, among other projects.

Work is proceeding on the K-25 History Center, Oak Ridge Fire Chief Darryl Kerley said in a July 21 memo to City Manager Mark Watson. The K-25 History Center is a project of the U.S. Department of Energy and UCOR, DOE’s cleanup contractor in Oak Ridge.

As that project proceeds, several upgrades will be needed to the first floor of the city-owned fire station in order to create the required living space for fire department personnel, Kerley said. [Read more…]

Oak Ridge National Laboratory will reduce its workforce by up to 350 positions by the end of the calendar year, ORNL Director Thomas Zacharia said in a Tuesday morning email to employees.

The workforce restructuring plan has been proposed by UT-Battelle and approved by the U.S. Department of Energy, Zacharia said. ORNL is DOE’s largest multiprogram science and energy laboratory.

“From time to time, sustaining our work effectively and efficiently requires the most difficult of decisions, which is to reduce our staff in certain areas of the lab,” Zacharia said. “To allow us to provide for our research missions and to allocate resources most productively, the Department of Energy has approved a Workforce Restructuring Plan proposed by UT-Battelle that will reduce ORNL’s workforce by up to 350 positions by the end of the calendar year.”

Zacharia said the reductions will be made primarily among staff who charge to “indirect accounts,” along with some research staff affected by fiscal year 2017 funding who could not be placed elsewhere in the lab.

“By reducing these positions, ORNL will be able to maintain competitive chargeout rates while freeing resources for discretionary investments that will modernize lab infrastructure and maintain core research capabilities in the mission areas assigned to ORNL,” Zacharia said. [Read more…]

DOE: Pavement collapse at ORNL a significant distance from U-233 storage area

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. Measurements from different types of detectors are necessary for comprehensive studies of neutrinos at SNS. The scientists are standing in front of the cesium-iodide-detector shielding.

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.
