Demolition work should be complete this month on K-27, the last of the big five buildings once used to enrich uranium for nuclear weapons and commercial nuclear power plants at the former K-25 site in west Oak Ridge, officials said last week.

Demolition work started on K-27 in February.

Like the other four buildings that have already been demolished, the four-story, 383,000-square-foot K-27 building once used a process known as gaseous diffusion to enrich uranium.

The demolition is part of Vision 2016. That’s the plan by the U.S. Department of Energy Office of Environmental Management, or EM, to remove all five gaseous diffusion buildings from the site by the end of the year.

Federal officials said it’s the first time in the world that a uranium enrichment complex has been cleaned and removed. [Read more…]

In February 2016, demolition crews started tearing down the K-27 gaseous diffusion building.

Now, only months later, the Oak Ridge Office of Environmental Management and its contractor UCOR have already completed demolition on more than 65 percent of the four-story, 383,000-square-foot facility, the U.S. Department of Energy said.

K-27 is the last of five large gaseous diffusion facilities to be torn down at the East Tennessee Technology Park, or ETTP, which was formerly known as the Oak Ridge Gaseous Diffusion Plant and often referred to as the former K-25 site.

“Due to the heavy contamination and state of the 1940s facility, K-27 was one of the environmental management’s highest cleanup priorities,” the DOE Office of Environmental Management, or EM, said in a May 31 newsletter. “The progress taking down the facility moves EM closer to fulfilling its Vision 2016—the removal of all five gaseous diffusion buildings from the site by year’s end. It is not only a significant goal for EM and Oak Ridge, but it will also mark the first time in the world that a uranium enrichment complex has been cleaned and removed.” [Read more…]

Demolition started Monday on K-27, the last of the big five uranium-enriching buildings at the former K-25 site, and officials expect the work to be complete by the end of the year.

The five buildings—K-25, K-27, K-29, K-31, and K-33—once used a process called gaseous diffusion to enrich uranium for atomic weapons and commercial nuclear power plants. Officials credit them for helping to win World War II and end the Cold War, and for playing significant roles in technological developments and the nuclear industry.

The K-25 site, which is now known as East Tennessee Technology Park or Heritage Center, was built during World War II as part of the Manhattan Project, a top-secret federal program to build the world’s first nuclear weapons. The site is now slowly being converted into a large industrial park.

“The majority of the property will be reused,” said Ken Rueter, president and project manager for UCOR, or URS |CH2M Oak Ridge LLC, the U.S. Department of Energy’s cleanup contractor in Oak Ridge. [Read more…]

Demolition now complete on four of five gaseous diffusion buildings

Demolition of the large K-31 Building in west Oak Ridge means that 200 acres of flat land are now available for industrial development at East Tennessee Technology Park, officials said.

“It’s the largest parcel of land available at ETTP,” said Sue Cange, manager of the U.S. Department of Energy’s Oak Ridge Office of Environmental Management.

Infrastructure is already in place, including water, sewer, roads, and electricity, Cange said. Also, ETTP is close to Interstate 40, a short rail line, and possibly an airport. (There are plans to build an airport at the site, which is also known as Heritage Center.)

K-31 is the fourth of five gaseous diffusion buildings demolished at ETTP. The site, which has also been known as K-25 and Oak Ridge Gaseous Diffusion Plant, was built during the Manhattan Project in World War II as part of a top-secret federal program to build the world’s first atomic bombs. Officials say it helped to win the Cold War, enriching uranium for commercial nuclear power plants and nuclear weapons.

But operations ended in 1985, and the site was permanently shut down in 1987. DOE then began cleanup operations and—with the help of contractors, a nonprofit organization, and others–is converting it into a large private industrial park. [Read more…]

Chevrolet Cavalier Crash at Highway 95

The driver of this Chevrolet Cavalier was flown by a medical helicopter to a hospital after apparently crashing through a guardrail and into a rock embankment, right, below a DOE haul road on Highway 95 in west Oak Ridge on Wednesday afternoon.

 

A car driver was flown by medical helicopter to a hospital after crashing through a guardrail and into a rock embankment below a U.S. Department of Energy haul road that crosses over Highway 95 in west Oak Ridge on Wednesday afternoon.

The name and condition of the driver weren’t immediately available after the one-vehicle, one-person crash. The collision occurred in a curvy section of Highway 95 near the western entrance to the Y-12 National Security Complex on Bear Creek Road.

The haul road is used to move debris from the East Tennessee Technology Park, the former K-25 site, to the Environmental Management Waste Management Facility west of Y-12. [Read more…]

Oak Ridge Reservation with Bear Creek Valley

The proposed Environmental Management Disposal Facility would be built between the Y-12 National Security Complex and the Environmental Management Waste Management Facility, or EMWMF.

 

Oak Ridge officials will discuss the community impact of a proposed landfill that would hold waste from cleanup work at federal sites during a work session on Friday.

The Oak Ridge City Council work session is scheduled from 10 to 11:30 a.m. Friday, May 8, in the Municipal Building Training Room.

Council will be briefed on the Draft Community Impact Assessment of the proposed Environmental Management Disposal Facility by Karl Kalbacher, project manager for The Ferguson Group, a company that helps the city with its federal legislative agenda in Washington, D.C.

The Environmental Management Disposal Facility would be built on Bear Creek Road west of the Y-12 National Security Complex near another landfill that is already in use and has been operating since 2002. It could cost $1 billion, including construction and 23 years of operations. [Read more…]

New DOE landfill could cost $1 billion, including construction, operations

Oak Ridge Reservation with Bear Creek Valley

But it could also save $1 billion through on-site disposal, officials say

A new landfill that would hold waste from cleanup work at federal sites in Oak Ridge could cost $1 billion, a project manager said Wednesday. That start-to-finish estimate includes construction and 23 years of operations.

But federal officials said the new landfill could save $1 billion in on-site versus off-site costs. That’s because the waste would be disposed on site and wouldn’t have to be shipped out of town, possibly to other states such as Nevada and Utah.

Saving money through on-site disposal could, in turn, accelerate the cleanup work at Oak Ridge National Laboratory and Y-12 National Security Complex, said Laura Wilkerson, federal project director for the Y-12 National Security Complex in the Oak Ridge Office of Environmental Management.

The new landfill, the Environmental Management Disposal Facility, would be built on Bear Creek Road west of the Y-12 National Security Complex near another landfill that is already in use and has been operating since 2002. [Read more…]

Avisco, a long-term U.S. Department of Energy contractor based in Oak Ridge, has announced a plan to phase out of their existing contracts and eventually close the company after 30 years of operations.

In a Tuesday press release, company owner Avis A. Phillips said she decided it was time to wind down Avisco after long discussions with her family.

“I have thoroughly enjoyed all the years we’ve worked with a terrific group of clients and a wonderful team of employees,” Phillips said. “It’s the association with our great staff that makes this decision particularly difficult. I can never thank them enough.” [Read more…]

DOE responds to SSAB’s waste disposal recommendation

Submitted

The U.S. Department of Energy’s Oak Ridge Office of Environmental Management has responded to a recommendation made earlier this year by the Oak Ridge Site Specific Advisory Board.

In May, the federally appointed citizens’ panel recommended that DOE continue to plan for additional on-site waste disposal capacity on the DOE Oak Ridge Reservation, or ORR, for low-level radioactive and chemically hazardous waste.

DOE currently operates the Environmental Management Waste Management Facility, or EMWMF, a low-level radioactive waste disposal facility in Bear Creek Valley near the Y-12 National Security Complex. When the facility began accepting waste in 2002, it was expected to handle all projected low-level waste from cleanup operations on the ORR. However, with the amount of demolition and work left to complete, EM requires additional disposal capacity onsite.

DOE has conducted a study to develop, screen, and evaluate alternatives for an additional waste disposal facility, with a working name of EM Disposal Facility, or EMDF. ORSSAB’s recommendation encouraged the agency to continue working toward adding disposal capacity and proposed recommendations for a new facility.

The ORSSAB encouraged DOE to minimize the need for additional on-site capacity when possible. In its response, DOE said it was examining the final cover design of the EMWMF to allow for extended capacity. The waste acceptance criteria for other so-called “sanitary landfills” on Chestnut Ridge are being evaluated for possible modifications to allow a wider variety of waste. [Read more…]

The field work is complete on 27 cleanup projects at three federal sites in Oak Ridge that used $751 million in Recovery Act funds.

The U.S. Department of Energy’s Oak Ridge Office of Environmental Management, or EM, announced the end of the field work on Thursday.

“We’re done knocking down buildings and with all the work in the field,” said Mike Koentop, executive officer in Oak Ridge Office of Environmental Management. “We have paperwork left to do to close out projects.”

The American Recovery and Reinvestment Act of 2009, also known as the Recovery Act or stimulus bill, was passed by Congress and signed by President Barack Obama in February 2009. It was meant to help stimulate an economic recovery during the depths of the Great Recession, and it was intended to address long-neglected infrastructure projects and programs.

In Oak Ridge, the Recovery Act funding paid for several demolition projects such as the demolition of the 1.4-million-square-foot K-33 Building at the East Tennessee Technology Park and other projects ranging from mercury reduction at the Y-12 National Security Complex to transuranic waste processing at Oak Ridge National Laboratory.

Demolition work began Tuesday on the last section of the historic K-25 Building, which was erected to enrich uranium for atomic bombs during World War II and was once the world’s largest building under one roof.

Most of the building, which is in west Oak Ridge, has already been demolished. Only a small section of the east wing remains at the former mile-long, U-shaped building.

K-25 was built during the top-secret Manhattan Project in World War II to enrich uranium for nuclear weapons through a process known as gaseous diffusion. Those operations ended in 1964. [Read more…]
