The U.S. Department of Energy is requesting more time to complete projects to commemorate the historic contributions of the former K-25 site in west Oak Ridge.

Built during World War II, the K-25 site helped enrich uranium for the first atomic bomb used in wartime as part of the top-secret Manhattan Project. The plant continued to enrich uranium for nuclear weapons and commercial nuclear power plants after the war, and those who have worked at the site have said it helped win the Cold War.

The history of the site will be honored by preserving the concrete slab of the former K-25 Building, building a Viewing Tower and replica Equipment Building on the south side of the building site, and opening a K-25 History Center on the second floor of the adjacent Oak Ridge Fire Station Number 4.

A historical interpretation agreement was signed in August 2012. But it expires this August. And the roughly $20 million worth of projects won’t be complete by then.

DOE is making “good progress,” but “the reality is we need a little more time,” said Dave Adler, acting deputy manager for DOE’s Oak Ridge Office of Environmental Management. Adler and Steve Cooke, K-25 preservation coordinator for DOE, briefly discussed the proposed amendment to the agreement during a Tuesday evening work session with the Oak Ridge City Council.

(For members) Three national labs building exascale computers

Posted at 6:39 pm February 4, 2019
By John Huotari Leave a Comment

Three national laboratories, including Oak Ridge National Laboratory, are building new computer systems that could be many times more powerful than today’s top supercomputers.

The new machines are exascale systems. None have been delivered yet, but the planning for them started more than a year ago and the new high-performance systems could be delivered to the three laboratories in the next several years. Planning for the exascale computers was under way even before the world’s most powerful supercomputer, a petaflop system called Summit at ORNL, was unveiled in June 2018.

Exascale computers could be 50 to 100 more powerful than today’s petaflop computers, according to the U.S. Department of Energy. Besides ORNL, they could be located at Argonne National Laboratory southwest of Chicago and Lawrence Livermore National Laboratory east of San Francisco. The first system is expected at Argonne, followed by a second system at ORNL.

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…]

K-25 Equipment Building & Viewing Tower: Design complete, construction funding available

The design is complete and funding is available for the construction of an Equipment Building and Viewing Tower that will help commemorate the history of the K-25 Building, once the world’s largest building under one roof.

K-25 was built in Oak Ridge during World War II to help enrich uranium for the Manhattan Project. That was a top-secret federal program to build the world’s first atomic weapons. During the war, Oak Ridge enriched the uranium for “Little Boy,” the first atomic bomb used in wartime. “Little Boy” was detonated over Hiroshima, Japan, on August 6, 1945, shortly before the end of World War II.

After the war, the four-story, 44-acre K-25 Building and four other large buildings at the K-25 site continued to use a process known as gaseous diffusion to enrich uranium for atomic weapons and commercial nuclear power plants. Officials say the K-25 site, which is in west Oak Ridge, helped win the Cold War.

After decades of use, the K-25 site was shut down in the mid-1980s, and as part of a cleanup effort in recent years, the five large gaseous diffusion buildings have been demolished. But the history of the K-25 building and the site will live on in a History Center on the second floor of Oak Ridge Fire Station Number 4, which is next to K-25’s concrete slab, and at the Equipment Building and Viewing Tower, which will be just west of the History Center.

The History Center, Equipment Building, and Viewing Tower will be on the south side of the former K-25 Building. The site is now known as Heritage Center or East Tennessee Technology Park. [Read more…]

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

Posted at 4:01 pm December 10, 2018
By John Huotari Leave a Comment

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 [email protected]. 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.

Neutron production at ORNL’s SNS reaches design power level

The Spallation Neutron Source at Oak Ridge National Laboratory has broken a new record by ending its first neutron production cycle in fiscal year 2019 at its design power level of 1.4 megawatts.

Higher power provides more neutrons for researchers who use the facility to study a wide range of materials, an ORNL press release said. The achievement marks a new operational milestone for neutron scattering in the United States and opens the door to studying significantly smaller materials with greater complexity, the press release said.

“The operation of SNS at 1.4 megawatts this cycle has been an outstanding achievement,” said Paul Langan, associate laboratory director for neutron sciences. “It reflects on the maturity of our facility and the high level of technical excellence of our engineering, operational, and scientific staff.”

The power increase was enabled by the combination of extensive improvements to the linear accelerator, including the recent replacement of the radio frequency quadrupole—the first accelerating structure of the accelerator’s frontend assembly, as well as improvements to the liquid mercury target.
