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.

The Oak Ridge City Council and U.S. Department of Energy will discuss a proposed amendment to a historical interpretation agreement on Tuesday evening.

The agenda for the non-voting Council work session does not give the purpose of the proposed amendment or say what it might do.

But it appears that the proposed amendment could be related to historical interpretation at the former K-25 site in west Oak Ridge because one of the DOE representatives scheduled to talk to Council is Steve Cooke, K-25 preservation coordinator for the U.S. Department of Energy. Also scheduled to talk to Council is Dave Adler, acting deputy manager for DOE’s Oak Ridge Office of Environmental Management. [Read more…]

Image from “Final Long-Term Management and Storage of Elemental Mercury Supplemental Environmental Impact Statement” published by U.S. Department of Energy in September 2013.

The U.S. Department of Energy is considering whether to lease space to store elemental mercury from sites across the country.

The facility could store about 1,200 metric tons (1,300 tons) of elemental mercury. The waste has been generated at sites in the United States, mostly at gold mining operations, according to the DOE Office of Environmental Management.

The mercury that could be stored at the leased facility is separate from the 1,200 metric tons of mercury stored at the Y-12 National Security Complex in Oak Ridge. The Y-12 mercury, about 2.6 million pounds stored in seamless steel flasks, was acquired for lithium-6 isotope separation operations for thermonuclear weapons.

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.

Federal employees of the Manhattan Project National Historical Park, which includes Oak Ridge, are back at work after the partial government shutdown ended Friday.

The shutdown started Saturday, December 22, and it lasted 35 days. It was the longest government shutdown ever.

During the shutdown, there were no National Park Service staff members or volunteers working at the Park Service desk at the Children’s Museum of Oak Ridge. The National Park Service did not monitor or update social media and websites during the shutdown, and it did not provide visitor services at the Manhattan Project National Historical Park, including public information. Also, all park programs were canceled.

The Manhattan Project National Historical Park said its staff resumed regular operations on Sunday after Congress passed and President Donald Trump signed a short-term continuing resolution that re-opened the government for three weeks. [Read more…]

U.S. nuclear forces could cost about $494 billion during a 10-year period if current plans are followed, according to the nonpartisan Congressional Budget Office.

The CBO is required by law to estimate the 10-year costs every two years. The new estimate is $494 billion for work between 2019 to 2028, the CBO said in a report published this month. That’s an average of just under $50 billion a year.

The Y-12 National Security Complex in Oak Ridge participates in the nuclear weapons work along with other U.S. Department of Energy sites and the U.S. Department of Defense.

The CBO said nuclear weapons have been an important part of U.S. national security since they were developed during World War II. Oak Ridge was the main production site for the top-secret project to build those first weapons, and Y-12 continues to work on nuclear weapons. One modernization program for the W76-1 warhead was recently completed, and another for the B61-12 bomb has started.

The CBO said nuclear forces were central to U.S. defense policy during the Cold War, and a large arsenal was built. [Read more…]

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…]

Y-12: Work complete on W76-1 warhead program

Note This story was updated at 4:40 p.m. Jan. 26.

After two decades, work was completed in December on a program to extend the life of the W76 nuclear warhead, the Y-12 National Security Complex said on Monday.

That ended a decade of work to extend the service life of the original warhead design by 40 years, Y-12 said.

“This warhead plays a vital role in maintaining the nation’s credible nuclear deterrent,” said Consolidated Nuclear Security LLC, which manages and operates Y-12 for the National Nuclear Security Administration.

The Life Extension Program, or LEP, is for the W76-1 warhead. The W76-1 is a refurbished W76-0 warhead. The W76-0 warhead is a submarine-launched ballistic missile system that was first introduced into the stockpile for the U.S. Navy in 1978. The warhead is deployed with Trident II D5 missiles on Ohio-class nuclear ballistic missile submarines. [Read more…]
