On Monday, the Y-12 National Security Complex began limited operations and transitioning to mission-critical operations. The change is in response to the COVID-19 pandemic. For now, all non-essential personnel will leave the 811-acre nuclear weapons production plant in Oak Ridge, and employees who can telework will continue to do so.

“Since mid-March, Y-12 has been in a preventive phase of its pandemic plan,” the site in a a response to questions on Wednesday. The response was provided by spokesperson Kathryn King of Consolidated Nuclear Security, a federal contractor that manages and operates Y-12 and another nuclear weapons production plant, the Pantex Plant northeast of Amarillo, Texas.

“With additional cases now confirmed at Y-12 and the growing number of cases in East Tennessee, the plant is transitioning to a ‘containment’ phase that ensures mission-critical operations while further protecting the Y-12 workforce and the community,” the response said. “In the containment phases, all non-essential plant personnel will leave the site until further notice. Employees who are able to telework will continue to do so.”

CNS said all Y-12 processes, systems, and facilities will be maintained in safe and secure configurations. Key mission activities related to stockpile stewardship and modernization, and key infrastructure and reestablishment of production capabilities, will continue.

The K-25 History Center will have a grand opening ceremony on Thursday, February 27.

The ceremony, which will include a ribbon-cutting, is scheduled for 10:30 a.m. Thursday, February 27, at 652 Enrichment Street in west Oak Ridge.

The K-25 site, now known as Heritage Center, was built during World War II to help enrich uranium for the top-secret Manhattan Project, a federal program to build the world’s first atomic bombs. K-25 helped enrich uranium for “Little Boy,” a nuclear weapon dropped over Hiroshima, Japan, on August 6, 1945, shortly before the end of World War II.

After the war, K-25 enriched uranium for nuclear weapons and commercial nuclear power plants through the Cold War. The site was shut down in the mid-1980s, and it is being cleaned up and converted into a private industrial park. The site’s large uranium enrichment buildings have been demolished and so have many of the support buildings. Most of the cleanup is expected to be completed this year.

Work began in June to build the Mercury Treatment Facility at the Y-12 National Security Complex.

The Mercury Treatment Facility will allow the U.S. Department of Energy to clean up and demolish several large Y-12 buildings that used mercury to separate lithium for nuclear weapons during the Cold War in the 1950s and 1960s. The facility is expected to help reduce the amount of mercury in East Fork Poplar Creek, which flows through Oak Ridge.

DOE announced in December that it had awarded a $91 million contract to build the Mercury Treatment Facility. The contract, which could be in place for up to four years, was awarded to APTIM-North Wind Construction JV LLC.

A groundbreaking was held at the site in November 2017, and site preparations were completed by December 2018.

Almost 700 kilograms of highly enriched uranium has been moved from the United Kingdom to the United States, and the material is being securely stored at the Y-12 National Security Complex in Oak Ridge for now, federal officials said.

The National Nuclear Security Administration said this month that the highly enriched uranium, or HEU, will be down-blended later into low enriched uranium for use as nuclear reactor fuel.

“The material was returned to Y-12 for secure storage awaiting future disposition,” the NNSA said in a statement provided Friday by Steven Wyatt of the NNSA Production Office in Oak Ridge.

Wyatt said Y-12 supported the removal effort, which was announced by the NNSA on May 3, through technical oversight and guidance of the processing and packaging of material.

The U.S. Department of Health and Human Services has designated a class of Y-12 employees to be added to a federal worker compensation program that involves certain illnesses and work at sites like Y-12 that are affiliated with the U.S. Department of Energy.

The employees who could be added, unless Congress says otherwise, would have worked at Y-12 between January 1, 1958, and December 31, 1976, when the plant was manufacturing nuclear weapons components during the Cold War. They would have had an aggregate total of at least 250 work days. They could have been employees of DOE, its predecessor agencies, or their contractors and subcontractors.

Oak Ridge Today has previously reported that the workers could be added to the compensation program based on exposure to radiation from thorium metal parts and plutonium-241 isotopes.

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.

Watts Bar Nuclear Plant

The U.S. Nuclear Regulatory Commission announced on Monday that there would be no significant impact from producing tritium for nuclear weapons in a second unit at the Watts Bar Nuclear Power Plant in Rhea County.

The project involves the Y-12 National Security Complex in Oak Ridge.

The tritium could be produced in Unit 2 at Watts Bar, which is near Spring City about 45 miles southwest of Oak Ridge.

Tritium, which boosts the yields of nuclear weapons, is already being produced in Watts Bar Unit 1. The Tennessee Valley Authority has been producing tritium there since 2003.

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.

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…]

Canned subassembly certified four months ahead of schedule

The Y-12 National Security Complex on Monday said it has completed a major milestone in efforts to refurbish components for a strategic nuclear weapons system that is vital to the U.S. nuclear deterrent.

The first production unit for a bomb called the B61-12 was certified at Y-12 on December 6, 2018.

The work is part of the B61 Life Extension Program, or LEP. The B61 is a nuclear bomb that can be carried on several types of military aircraft. The B61 LEP will extend the life of this strategic weapon for 20 years, said Consolidated Nuclear Security LLC, which manages and operates Y-12 for the National Nuclear Security Administration.

B61 bombs are the oldest nuclear weapons in the nation’s active stockpile. They have been in service almost 50 years, and critical components of the bombs are reaching the end of their operational lives. The B61 was first “fielded” in 1968, and current modifications were fielded between 1979 and 1991, according to the U.S. Government Accountability Office. [Read more…]

The U.S. Department of Energy announced Tuesday that it has completed the site preparations for the construction of the Mercury Treatment Facility at the Y-12 National Security Complex.

The Mercury Treatment Facility will allow DOE to clean up and demolish several large Y-12 buildings that used mercury to separate lithium for use in nuclear weapons during the Cold War (in the 1950s and 1960s). It’s part of a large-scale cleanup and demolition project at Y-12 and an effort to reduce the amount of mercury in East Fork Poplar Creek, which flows through Oak Ridge.

DOE announced on Tuesday, December 4, that it had awarded a $91 million contract to build the Mercury Treatment Facility at Y-12. The contract, which could be in place for up to four years, was awarded to APTIM-North Wind Construction JV LLC.

DOE said early site preparation activities were started by other contractors in December 2017. A groundbreaking was held at the site in November 2017, and UCOR, DOE’s lead cleanup contractor in Oak Ridge, began work at the treatment facility site with a subcontractor after the groundbreaking, the DOE Oak Ridge Office of Environmental Management said in a story published Tuesday in an EM Update.

The Mercury Treatment Facility will have two components: a headworks facility and a treatment plant connected by a pipeline. The headworks facility will capture creek flow on the west end of Y-12, store excess stormwater collected during large rainfalls, remove grit, and pump water through the pipeline to the treatment plant on the east side of Y-12. The treated water will then flow into East Fork Poplar Creek. [Read more…]
