The National Park Service will not provide visitor services during the partial government shutdown that started Friday night, and that could affect programs in Oak Ridge and other national parks in the area. But Manhattan Project Park locations at three sites, including Oak Ridge, will remain open to the public and continue to provide visitor services.

Oak Ridge is part of the Manhattan Project National Historical Park, which is part of the National Park Service. The park, which is about three years old, commemorates the Manhattan Project, a top-secret federal program to build the world’s first atomic weapons during World War II. Besides Oak Ridge, two other sites are part of the park: Hanford, Washington, and Los Alamos, New Mexico.

In Oak Ridge, the Manhattan Project National Historical Park is based at the Children’s Museum on West Outer Drive. The park includes programs such as historical films, celebrations, and programs, and informative hikes and bicycle rides with rangers.

The National Park Service did not respond to two inquiries this week, but a program scheduled for Saturday afternoon in Oak Ridge will presumably be canceled. That program was intended to discuss secrecy, security, and spies during the Manhattan Project. It was scheduled for this afternoon (Saturday, December 22) at the Turnpike Gatehouse in west Oak Ridge. [Read more…]

MCGHEE TYSON AIRPORT—A layout plan has been submitted for the proposed Oak Ridge Airport, and now officials are waiting for a response from the Federal Aviation Administration.

The response could arrive any day, said Bill Barley, vice president of CHA Consulting, which has an office in Louisville. Barley and Mike Reiter of Michael Baker International, an architectural firm, gave an update about the Oak Ridge Airport project during a meeting of the Metropolitan Knoxville Airport Authority Board of Commissioners at McGhee Tyson Aiport in Alcoa on Wednesday.

The letter from the FAA could be a conditional approval, which is standard, Barley said.

If approved and funded, the airport would have a 5,000-foot runway, and it would be built on the south side of the East Tennessee Technology Park, the former K-25 site in west Oak Ridge. It would be near Highway 58, on 170 acres of land that have been declared excess by the U.S. Department of Energy. The runway could run roughly parallel to the highway.

The U.S. Department of Energy on Wednesday named a deputy cleanup manager in Oak Ridge.

The new deputy manager, Laura Wilkerson, has been selected as the deputy manager of the Oak Ridge Office of Environmental Management, or OREM. That’s the program responsible for cleanup projects at federal sites in Oak Ridge, including the East Tennessee Technology Park (the former K-25 site), Oak Ridge National Laboratory, and Y-12 National Security Complex.

Wilkerson previously served as the director of OREM’s Planning and Execution Division, a press release said. She has more than 25 years of federal service. [Read more…]

The U.S. Department of Energy announced Tuesday that it has completed the site preparations for the construction of the Mercury Treatment Facility at the Y-12 National Security Complex.

The Mercury Treatment Facility will allow DOE to clean up and demolish several large Y-12 buildings that used mercury to separate lithium for use in nuclear weapons during the Cold War (in the 1950s and 1960s). It’s part of a large-scale cleanup and demolition project at Y-12 and an effort to reduce the amount of mercury in East Fork Poplar Creek, which flows through Oak Ridge.

DOE announced on Tuesday, December 4, that it had awarded a $91 million contract to build the Mercury Treatment Facility at Y-12. The contract, which could be in place for up to four years, was awarded to APTIM-North Wind Construction JV LLC.

DOE said early site preparation activities were started by other contractors in December 2017. A groundbreaking was held at the site in November 2017, and UCOR, DOE’s lead cleanup contractor in Oak Ridge, began work at the treatment facility site with a subcontractor after the groundbreaking, the DOE Oak Ridge Office of Environmental Management said in a story published Tuesday in an EM Update.

The Mercury Treatment Facility will have two components: a headworks facility and a treatment plant connected by a pipeline. The headworks facility will capture creek flow on the west end of Y-12, store excess stormwater collected during large rainfalls, remove grit, and pump water through the pipeline to the treatment plant on the east side of Y-12. The treated water will then flow into East Fork Poplar Creek. [Read more…]

DOE cleanup: Comment period for EMDF ends at 5 p.m. today

The comment period ends at 5 p.m. today (Monday, December 10) for the proposed landfill that the U.S. Department of Energy could use in central Bear Creek Valley west of the Y-12 National Security Complex.

The landfill would be used as the existing landfill, also west of Y-12, fills up as DOE cleanup work shifts from East Tennessee Technology Park (the former K-25 site) to Y-12 and Oak Ridge National Laboratory, possibly after 2020. The new landfill would be called the Environmental Management Disposal Facility. The existing landfill is the Environmental Management Waste Management Facility.

The public comment period for the proposed plan for the new facility was extended until December 10. DOE will accept written comments on the proposed plan at any time during the public comment period. You can send your comments via email at John.Japp@orem.doe.gov. Also, you can mail comment to Mr. John Michael Japp at P.O. Box 2001, Oak Ridge, TN 37831.

Copies of the EMDF Proposed Plan are available at the DOE Information Center. It is also available online at https://doeic.science.energy.gov/uploads/A.0100.030.2596.pdf.

Experiments and isotope production have been affected, but employees are still able to carry out their normal duties at the High Flux Isotope Reactor as the U.S. Department of Energy investigates a slightly elevated radiation level in HFIR’s primary cooling system.

The High Flux Isotope Reactor, which is used for research and isotope production, is at Oak Ridge National Laboratory.

In a response to questions on Wednesday, ORNL Communications Director David Keim said the slightly elevated reading in the primary cooling system was well below alarm levels.

“The HFIR operators promptly responded to the reading and placed the reactor in a safe condition,” Keim said. [Read more…]

Note: This story was updated with a statement from CNS at 11:50 a.m. Nov. 19.

The U.S. Department of Energy has notified Consolidated Nuclear Security that it intends to investigate possible weaknesses in nuclear criticality controls at the Y-12 National Security Complex.

The DOE Office of Enterprise Assessments’ Office of Enforcement notified CNS, which manages and operates Y-12, of its intent to investigate on Tuesday. The Office of Enforcement intends to investigate potential noncompliances with DOE nuclear safety program requirements, according to a summary of the notice published online.

The potential nuclear criticality control weaknesses were identified at Y-12 between May 2017 and May 2018, the notice said.

Nuclear criticality occurs when nuclear fuel is capable of sustaining a fission chain reaction. [Read more…]

Researchers at Oak Ridge National Laboratory have demonstrated a 120-kilowatt wireless charging system for vehicles—providing six times the power of previous ORNL technology and a big step toward charging times that rival the speed and convenience of a gas station fill-up.

The wireless system transfers 120 kilowatts of power with 97 percent efficiency, which is comparable to conventional, wired high-power fast chargers. In the laboratory demonstration, power was transferred across a six-inch air gap between two magnetic coils and charged a battery pack.

ORNL researchers created and demonstrated the world’s first 20-kilowatt wireless charging system, which is being modified for applications such as commercial delivery trucks.

“It was important to maintain the same or smaller footprint as the previous demonstration to encourage commercial adoption,” said project lead Veda Galigekere of ORNL’s Power Electronics and Electric Machinery Group. [Read more…]

The Y-12 National Security Complex in Oak Ridge has been approved to produce a major component of a nuclear bomb known as the B61-12.

The approval was the final step to authorize the manufacturing and delivery of the first production unit of a component called the canned subassembly. It’s scheduled for March 2019, according to Y-12. A canned subassembly is the second stage of a modern thermonuclear weapon, and it is part of the nuclear explosives package.

The Y-12 work is part of the B61-12 Life Extension Program, which will consolidate four versions of the bomb into one. The bombs could be carried on B-2A bomber aircraft and F-15Es, several types of F-16s, and PA-200 fighters, and in the future, F-35s and B-21s.
