They haven’t agreed on a final budget number, but the Trump administration and the U.S. House and Senate have proposed spending between about $33 million and $52 million in the next fiscal year to continue disposing of uranium-233 waste materials that are stored at Oak Ridge National Laboratory in a building that is the oldest continuously operating nuclear facility in the U.S. Department of Energy complex.

The uranium-233, or U-233, waste is now stored in secure vaults in Building 3019, which was built in the 1940s at ORNL. Removing the waste could allow ORNL to relax its overall security posture, which will reduce costs, eliminate nuclear safety issues, and make the campus more conducive to collaborative science, according to a U.S. Senate Appropriations Committee report published in July.

Some of the waste is from a 1960s research and development test in New York, and it is being shipped to the Nevada National Security Site, a former nuclear weapons proving ground about 65 miles northwest of Las Vegas. In interviews this summer, DOE officials in Oak Ridge declined to discuss the amount of that waste that has been shipped to Nevada or to say how long the shipments might continue. But they are making progress, said Jay Mullis, acting manager of DOE’s Oak Ridge Office of Environmental Management.

Once all of those materials are shipped, the remaining U-233 at ORNL will be treated in “hot cell” facilities across the street from Building 3019, at Building 2026. The DOE’s Oak Ridge Office of Environmental Management owns both buildings.

Mullis said there is other U-233 waste stored in Building 3019, including from glovebox research at ORNL, from reactor plates, and from conglomerate materials. [Read more…]

Demolition work on K-27, last of big 5 uranium-enrichment buildings, to be complete this month

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…]

Council to discuss impact of proposed DOE landfill during Friday meeting

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…]

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…]

Demolition begins on last section of historic K-25 Building

K-25 East Wing Demolition

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…]
