Oak Ridge’s environmental management, or EM, program and contractor URS | CH2M Oak Ridge have prevented more than 1,000 pounds of mercury from entering the environment at the Y-12 National Security Complex.

This work, part of the U.S. Department of Energy’s Excess Contaminated Facilities initiative, enables demolition and disposal of massive mercury-contaminated equipment to begin this month.

Workers are inspecting and cleaning the pipes and column exchange (COLEX) equipment on the west side of Alpha-4 at Y-12. They have tapped and drained approximately 2,100 feet of the 5,700 feet of piping so far, retrieving large amounts of mercury, and more is expected as work continues. EM will address and remove the remaining portions on the facility’s east and south sides in the future.

“This project has proven to be a very successful investment for our program,” said Oak Ridge Office of EM Acting Manager Jay Mullis. “We set out to remove risks and enhance safety through the Excess Contaminated Facilities initiative, and our efforts at Alpha-4 will prevent thousands of pounds of mercury from leaking into the environment.” [Read more…]

Construction could start this year on the K-25 History Center at the East Tennessee Technology Park in west Oak Ridge, federal officials said. Plans also call for an Equipment Building and Viewing Tower at the site. Although the projects depend upon funding, the goal is to finish the work by 2019.

The K-25 site was one of three large sites built by the federal government in Oak Ridge during World War II to help make the world’s first atomic weapons as part of the top-secret Manhattan Project. The other two sites were X-10, which is now known as Oak Ridge National Laboratory, and Y-12, now the Y-12 National Security Complex.

At K-25, the three history-related facilities will have three missions. The History Center will tell the story of the workers. The Equipment Building will focus on the technology. And the Viewing Tower will show visitors the size of the site. All three facilities will be on the south side of the former mile-long, U-shaped K-25 Building.

K-25 used a process called gaseous diffusion to enrich uranium for atomic weapons and, later, for commercial nuclear power plants. Officials and contractors have said that K-25 helped win the Cold War. The site is now known as Heritage Center or East Tennessee Technology Park.

Preserving its history is part of a Memorandum of Agreement that was signed in August 2012 and allowed for the complete demolition of K-25, once the world’s largest building under one roof. The historic preservation work is expected to cost about $20 million total. [Read more…]

Biology Complex at Y-12 once housed more individuals with doctorates than anywhere else in the world

The U.S. Department of Energy and its cleanup contractor finished characterizing the Biology Complex at the Y-12 National Security Complex this month, identifying contaminants before demolishing and disposing of the buildings.

The characterization work was done by DOE’s Oak Ridge Office of Environmental Management and its contractor, URS | CH2M, or UCOR.

DOE said it was crucial to get crews into the complex before the working environment became too hazardous.

“Already, team members could not enter a building due to a failed roof,” the Department of Energy said in a story published online on Thursday. “Elsewhere, exterior tiles have fallen from the façade, and asbestos and other material present risks to workers due to roof leaks.”

Jay Mullis, acting manager for the Oak Ridge Office of Environmental Management, said the completion of the characterization work sets up the cleanup program to demolish Y-12’s Biology Complex when funds become available. [Read more…]

Site preparation could start later this year for the Mercury Treatment Facility at the Y-12 National Security Complex as the U.S. Department of Energy prepares for demolition and cleanup work at the nuclear weapons plant.

DOE’s Oak Ridge Office of Environmental Management, or OREM, expects to complete demolition and cleanup work at the East Tennessee Technology Park, the former K-25 site, in 2020. It will then focus on the large-scale demolition work at Y-12.

Among the Y-12 buildings that could be demolished are Alpha 4, Alpha 5, and Beta 4, all large buildings where mercury, a toxic metal, was once used. The buildings used mercury to separate lithium for nuclear weapons. The lithium separation operations started in 1955 and ended in 1963.

But before that cleanup work can begin, OREM needs the Mercury Treatment Facility. The plant was first announced at a press conference featuring U.S. Senator Lamar Alexander, a Tennessee Republican, about four years ago, in May 2013.

“This water treatment plant is a major step in addressing one of the biggest problems we have from the Cold War era—mercury once used to make nuclear weapons getting into our waterways,” Alexander said at the time. [Read more…]

At a ceremony in Washington, D.C., on Wednesday, Energy Secretary Rick Perry honored the Oak Ridge Office of Environmental Management’s Wendy A. Cain as Federal Project Director of the Year for 2016, and a team under Cain’s oversight won a U.S. Department of Energy Achievement Award.

Cain, who oversees the cleanup portfolio at the East Tennessee Technology Park, was described as the best of DOE project management leadership. She earned the award by demonstrating exceptional leadership and project management acumen while overseeing the demolition of a former uranium enrichment facility. Her leadership, attention to detail, empowerment of team members, and fostering of open communications enabled the demolition of the K-31 Building at ETTP almost four months ahead of schedule and about $4 million under budget, a press release said.

“This is an incredible honor for Wendy and the Environmental Management program in Oak Ridge,” said Jay Mullis, acting manager of the Oak Ridge Office of Environmental Management, or OREM. “Everyone who works with Wendy knows how deserving she is of this distinguished award. She brings an impeccable work ethic and commitment to achieve our mission every day, and is representative of all the dedicated and skilled federal and contractor employees executing the important cleanup mission here.” [Read more…]

A new initiative by the Oak Ridge Office of Environmental Management is improving safety and preparing two of the federal sites—Oak Ridge National Laboratory and Y-12 National Security Complex—for cleanup and modernization, officials said. The initiative is an excess contaminated facilities initiative.

The congressionally funded cleanup initiative was stimulated by a report to Congress by the Governmental Accountability Office. The report noted that the U.S. Department of Energy designated more than 2,300 of its facilities as “excess,” meaning they’re not operating and no longer serve the department’s missions.

“Many of these facilities pose high risk from contamination and deteriorating structural integrities due to their age and the limited resources to maintain them,” the U.S. Department of Energy Office of Environmental Management, or EM, said in a story published January 31.

The Office of Environmental Management said more than a quarter of all DOE’s high-risk excess facilities are in Oak Ridge at either ORNL or Y-12. Y-12 has 90 excess facilities to address while ORNL has more than 200, DOE EM reported. [Read more…]

The Oak Ridge Office of Environmental Management and its cleanup contractor have finished demolishing another building at East Tennessee Technology Park, or ETTP, the former K-25 site in west Oak Ridge.

The work is part of an effort to advance toward Vision 2020, a goal to complete cleanup at ETTP by 2020 and continue transferring the remaining land to private industry, benefiting the regional economy, the U.S. Department of Energy Office of Environmental Management, or EM, said in a story published February 28.

The latest progress involves the removal of Building K-731. The Oak Ridge Office of Environmental Management, or OREM, and cleanup contractor URS | CH2M Oak Ridge LLC, or UCOR, began demolishing Building K-731 on August 30, moments after taking down the final pieces of Building K-27 and fulfilling Vision 2016. That was Oak Ridge’s ambitious goal to be the world’s first to successfully remove all of its former uranium enrichment facilities by the end of 2016. [Read more…]

The Oak Ridge Office of Environmental Management recently finished repairs to an aging Y-12 National Security Complex building as part of an initiative that is designed to improve safety, reduce cleanup costs, lower risks, and stabilize excess facilities that are contaminated and are expected to be demolished.

Maintaining the roofs of aging, contaminated facilities prevents water damage, the greatest threat to rapid deterioration and the spread of contamination. These factors create a more hazardous environment for future demolition crews that must enter the facility, and they increase the cost of cleanup exponentially.

“We are applying lessons we’ve learned from previous cleanup projects,” said Jay Mullis, acting manager of Oak Ridge Office of Environmental Management, or OREM. “Buildings that are neglected cause cleanup to be much more costly and complicated. Performing smaller tasks like this one to maintain facilities will create considerable savings by the time we begin major demolition at Y-12.” [Read more…]

The U.S. Department of Energy Office of Environmental Management and its cleanup contractor in Oak Ridge are taking steps to remove risks and help prepare excess facilities for eventual demolition at the Y-12 National Security Complex and Oak Ridge National Laboratory.

Oak Ridge is home to more than 350 excess facilities totaling more than six million square feet. Many of them are several decades old.

Alan Stokes, associate director for the Planning and Execution Division in Oak Ridge’s Environmental Management, or EM, program, said during a panel discussion this month at the 2017 Waste Management Symposium in Phoenix that Oak Ridge has more than a quarter of the “higher-risk” excess facilities in the entire DOE inventory.

Employees from the U.S. Department of Energy’s Oak Ridge Office of Environmental Management participated in Woodland Elementary’s Science, Technology, Engineering, and Math, or STEM, night on Thursday. Employees volunteered to help students from kindergarten through fourth grade forge a love for math and science and realize the possibilities these disciplines offer.

“It’s rewarding any time you can participate in the education process,” said Jay Mullis, director of the Engineering, Safety, and Quality Division with DOE’s Oak Ridge Office of Environmental Management. “These kids are in the stage when learning is new and fun, and it’s the perfect opportunity to lay a great foundation and appreciation of the sciences.”

The event involved numerous local sponsors and community groups that helped design and share fun, educational activities for students at Woodland Elementary in Oak Ridge. Kids had the opportunity to learn through robots, Legos, gummy bear catapults, astronomy, spaghetti and marshmallow tower-building competitions, and math code busters. Specifically, Environmental Management employees taught participants how to create their own lava lamps. [Read more…]
