The Oak Ridge team that mostly cleaned up the former K-25 site, demolishing five large gaseous diffusion buildings and more than 500 structures, has received a Secretary’s Achievement Award from U.S. Energy Secretary Jennifer Granholm. The work was done ahead of schedule and under budget, the U.S. Department of Energy said.

Granholm honored the DOE Office of Environmental Management team from Oak Ridge in a virtual ceremony Wednesday, a press release said.

K-25 was used to enrich uranium for nuclear weapons and commercial nuclear power plants from World War II to the 1980s.

It was the first removal of a uranium enrichment complex, and it cleared 13 million square feet of deteriorated, contaminated structures from the site, the press release said.

“The Secretary’s Achievement Award honors a group or team of DOE employees and contractors who accomplish significant achievements on behalf of the department, demonstrating cooperation and teamwork in attaining their goals,” the press release said. “The award was given to the Oak Ridge Vision 2020 Project Team based on its achievements from 2020.”

Cleanup crews started a $4.7 million project this month to reduce maintenance and operations costs at the Molten Salt Reactor Experiment, which was shut down 50 years ago at Oak Ridge National Laboratory.

The project is expected to save nearly $25 million in costs, the U.S. Department of Energy Office of Environmental Management said in an “EM Update” published Tuesday.

The cost-reduction project will relocate employees stationed at the decades-old facility. Personnel currently housed in the building will move to other site locations to help with other projects, the “EM Update” said.

The project is expected to enhance the facility’s electrical distribution, sump pump, fire suppression, and monitoring systems.

“Although it was shut down 50 years ago, certain systems within the reactor building have continued to operate to keep the facility safe and stable until it can be demolished,” said the “EM Update,” with the Oak Ridge story contributed by Mike Butler. [Read more…]

For first time in 30 years, Savannah River dissolving spent nuclear fuel from ORNL reactor

For the first time in 30 years, spent nuclear fuel from the High Flux Isotope Reactor at Oak Ridge National Laboratory has been dissolved at the Savannah River Site in South Carolina.

The work is important because it is expected to allow the reactor, known as HFIR, to continue its mission, according to the U.S. Department of Energy Office of Environmental Management.

HFIR, which uses highly enriched uranium, is one of the world’s most powerful nuclear research reactor facilities. It’s the highest flux reactor-based source of neutrons for research in the United States. Flux refers to the rate of flow of fluids, particles, or energy. In HFIR’s case, the flux is measured in neutrons per square centimeter per second. HFIR is used for neutron scattering and isotope production, among other missions.

ORNL will reach its maximum capacity for storing HFIR fuel in fiscal year 2020, the DOE Office of Environmental Management, or EM, said in an “EM Update” electronic newsletter on Tuesday. [Read more…]

Two Oak Ridge companies involved in federal cleanup work have received small business awards from a U.S. Department of Energy office.

Restoration Services Inc., or RSI, was named the Small Business of the Year during the 16th Annual DOE Small Business Forum and Expo in Kansas City, Missouri, on May 16-18.

Another Oak Ridge business, Scientific Sales Inc., or SSI, was named the 8(a)/Small Disadvantaged Business of the Year.

Awards were presented to a total of five small businesses, including RSI and SSI, during the expo in Kansas City this month. The companies support the U.S. Department of Energy’s environmental management, or EM, work. The awards, which were for fiscal year 2016, were from DOE’s Office of Small and Disadvantaged Business Utilization.

The other three EM-related businesses that received awards were: [Read more…]

UCOR, the U.S. Department of Energy’s cleanup contractor in Oak Ridge, received about $3.4 million for its performance from April through September 2016, or 94 percent of the total award fee available, federal officials said.

The Oak Ridge Office of Environmental Management, or OREM, recently issued the six-month fee determination scorecard for UCOR, or URS | CH2M Oak Ridge LLC, after completing its evaluation.

“Contractor award fee evaluations determine what will be paid based on performance against stated objectives in accordance with annual award fee plans,” the DOE Office of Environmental Management, or EM, said in the EM Update electronic newsletter on December 29. “EM releases information relating to contractor fee payments to further transparency.”

According to UCOR’s scorecard, the company received an overall rating of “very good” for project management and “high confidence” for cost and schedule based on cost and schedule indexes, the newsletter said. [Read more…]

New DOE plan calls for research, technology to help fight mercury contamination, including in Oak Ridge

Y-12 Process Buildings and Mercury Use Area

 

U.S. Department of Energy officials have released a new plan to address mercury contamination at the Oak Ridge Reservation in Tennessee and Savannah River Site in South Carolina. It advocates for research and the development of technologies that could resolve key technical uncertainties with mercury in environmental remediation, the deactivation and decommissioning of facilities, and processing waste in tanks.

The Oak Ridge Reservation and Savannah River Site both used mercury in industrial-scale processes. At the Oak Ridge Reservation, large quantities of mercury were used at the Y-12 National Security Complex from the early 1950s until the early 1960s. During the peak period of operations, according to estimates from the Oak Ridge Office of Environmental Management, or OREM, 700,000 pounds of a total 20 million pounds of mercury that were used were released into the surrounding environment.

Ongoing mercury abatement and remediation efforts at Y-12 that began in the 1980s have decreased overall mercury releases to the environment, the DOE Office of Environmental Management, or EM, said in a May 31 newsletter.

But elevated concentrations remain in certain water, soil, and facilities, federal officials said. [Read more…]

Oak Ridge Airport Development Plan

About 170 acres of land at a federal site in west Oak Ridge could be transferred to a nonprofit organization for a new general aviation airport that would feature a 5,000-foot runway and accommodate airplanes and helicopters.

The airport would be built on the south side of Heritage Center, which is also known as East Tennessee Technology Park and the former K-25 site. The runway would be close to and run roughly parallel to Oak Ridge Turnpike/State Route 58.

A draft environmental assessment, or EA, has been prepared for the property transfer. It evaluates the potential impacts of transferring the ETTP land from the U.S. Department of Energy to the nonprofit Metropolitan Knoxville Airport Authority. DOE and MKAA representatives will be available to discuss the proposed action during a public information session from 5-6:30 p.m. Wednesday, August 19, at the DOE Information Center. The Information Center is on the west end of the building that houses the Office of Scientific and Technical Information in east Oak Ridge.

No formal presentation is planned, and the public may stop by at any time during the session. [Read more…]
