Crews are nearly finished deactivating the second of three collections of old, mercury-contaminated equipment around the Alpha-4 facility at the Y-12 National Security Complex at Oak Ridge, a press release said.
The column exchange, or COLEX, structures are connected to the four-story 500,000-square-foot Alpha-4 building, which was used for uranium separation from 1944 to 1945. Workers finished installing the COLEX equipment in 1955 for lithium separation, a process that required large amounts of mercury. A significant amount of the mercury was lost into the equipment, buildings, and surrounding soils, and its cleanup is one of EM’s top priorities.

Awards recommended by Y-12 employees in 2021 focused on at-risk youth, food insecurity, mental health, and aid to frontline workers
Consolidated Nuclear Security, in partnership with East Tennessee Foundation, recently awarded 17 grants totaling $100,000 to nonprofit organizations in 10 East Tennessee counties: Anderson, Blount, Campbell, Claiborne, Hamblen, Knox, Monroe, Roane, Scott, and Sevier.
The CNS Employee Investment Advisory Committee at Y-12 National Security Complex reviewed dozens of grant proposals this year, conducted staff interviews, and made site visits before recommending funding based on the committee’s four focus areas for the year: at-risk youth, food insecurity, mental health, and aid to frontline workers.
With the latest round of community investment grants, Consolidated Nuclear Security topped $880,000 of investment in the East Tennessee community during the last five years, a press release said.

The biggest change for a water discharge permit drafted for the Y-12 National Security Complex is the construction and operation of a Mercury Treatment Facility, a state official said Tuesday.
The mercury treatment facility, which is under construction and could begin operating next year, is expected to capture and treat most of the mercury released as old, unused mercury-contaminated buildings, equipment, and soils are demolished and removed, especially on the west side of the nuclear weapons production site.
Millions of pounds of mercury were used at Y-12 in the 1950s and early 1960s to produce nuclear weapons parts. Roughly 60,000 pounds is estimated to remain in buildings and equipment, and an unknown amount was released into soils and sediments. About 1.3 million pounds is unaccounted for. Mercury is a top pollutant of concern on the federal Oak Ridge Reservation.

The waste shipped from the Y-12 National Security Complex that violated a solid waste permit in Nevada included small volumes of pressurized, non-flammable gases and an energetic material, but the shipments did not pose a safety risk, the U.S. Department of Energy said Thursday.
“These items were contained within a sealed, thick steel assembly that was disposed within a large metal box,” DOE said in response to questions. “Though the presence of these internal items were not known at the time of disposal, they do not pose any safety risk because the inner assembly is capable of containing any release of the small volumes of pressurized gases and the energetic material.”
The Department of Energy and the State of Nevada resolved regulatory actions related to the unauthorized shipments of the classified low-level radioactive waste in June. Oak Ridge Today reported about the settlement agreement on Wednesday, and the Nevada Division of Environmental Protection announced the agreement on Thursday. DOE also responded to questions about the shipments on Thursday, and the responses are included here.
At issue were 33 waste packages in 10 shipments from Y-12 to the Nevada National Security Site northwest of Las Vegas between January 2013 and December 2018. The shipments, which were quickly suspended, received publicity in July 2019 after Dan Brouillette, who was then deputy energy secretary, informed Nevada Governor Steve Sisolak about them. At the time, Nevada officials were already in a dispute with DOE about a half-ton of plutonium shipped to NNSS from the Savannah River Site in South Carolina.

The U.S. Department of Energy, National Nuclear Security Administration, and Nevada environmental regulators have agreed to a settlement after classified low-level waste shipped west from the Y-12 National Security Complex allegedly violated waste acceptance criteria at the Nevada National Security Site northwest of Las Vegas, according to documents posted online.Â
The waste shipments from Y-12 received significant publicity in news stories in 2019 after Nevada Governor Steve Sisolak demanded answers from the U.S. Department of Energy about what were described as unapproved waste shipments. The shipments were incorrectly labeled, according to a letter sent that summer to former Energy Secretary Rick Perry by Sisolak and U.S. senators Catherine Cortez Masto and Jacky Rosen. Sisolak said he learned about the shipments from Y-12 to Nevada from Dan Brouillette, who was then deputy energy secretary.
Waste shipments from Y-12 were suspended that July. They remained suspended for almost two years. Shipments of low-level waste resumed in May this year, according to the Defense Nuclear Facilities Safety Board. Work continues to obtain approval to dispose of weapons-related material, the DNFSB said.
The settlement agreement, which was signed in June, addresses reimbursement and factual findings, and it includes, as an attachment, information about how the shipments from Y-12 allegedly violated waste acceptance criteria at NNSS.

More than 4,000 fish and crayfish were killed by chlorinated water and mercury at the Y-12 National Security Complex in two series of incidents in 2018 and 2021.
The first series of incidents was likely caused by the release of mercury while crews were cleaning up and removing equipment at the Alpha-4 Building on the west side of Y-12, according to scientists and officials. Alpha-4 is the most contaminated of the four major mercury-contaminated buildings at Y-12. Millions of pounds of mercury were used at Y-12 decades ago to produce nuclear weapons parts. Removing mercury-contaminated buildings, equipment, and soil remains one of the top challenges of cleaning up the Oak Ridge Reservation.

The Y-12 National Security Complex has deployed a system to counter unauthorized drones. Y-12 produces parts for nuclear weapons and stores highly enriched uranium, among other guarded national security missions.
Oak Ridge Today reported in November 2018 that Y-12 was one of four sites housing special nuclear materials where the National Nuclear Security Administration was deploying systems to counter drones. Deployed by the Office of Defense Nuclear Security, the systems have the capability to detect, identify, track, and intercept unsanctioned and suspicious drones, the NNSA said in 2018. At that time, one system had already been deployed at Los Alamos National Laboratory in New Mexico.
The NNSA announced in a press release Monday that the system to counter unauthorized drones had been deployed at Y-12. The Y-12 system is intended to detect, identify, and track potentially malicious threats posed by drones, the NNSA said.
“The National Nuclear Security Administration Production Office (NPO) is announcing this deployment and the airspace restriction to the public to minimize the threat of unauthorized UAS (unmanned aircraft system) flights over Y-12,†said Teresa Robbins, NPO manager. “This will enhance our ability to effectively protect this vital national security facility.â€

A new fire station and emergency operations center are being built at the Y-12 National Security Complex.
They are pilot projects designed to streamline the efficiency and delivery of specific construction projects under $50 million, the National Nuclear Security Administration said in a press release.
The NNSA, which is part of the U.S. Department of Energy, and Y-12 managing and operating contractor Consolidated Nuclear Security had a groundbreaking ceremony for the fire station on Tuesday. A few blocks away, the emergency operations center (EOC) is already under construction.
The fire station replaces one built in 1947, and the EOC will be the home of the site’s operations center, which is currently located in a World War II-era building. “Together, these new facilities will replace two outdated buildings and enhance our emergency response capabilities,†said Gene Sievers, Y-12 site manager.

Protesters plan to hang a banner at a nuclear weapons production site in Oak Ridge early Friday afternoon that will declare the weapons illegal under a United Nations treaty.
The banner, which will say “Nuclear Weapons Are Illegal,” will be hung on a fence across from the main entrance to the Y-12 National Security Complex on Scarboro Road. The banner will be hung after parts of the international agreement—the Treaty on the Prohibition of Nuclear Weapons—are read, organizers said.
Protesters said they also plan to hang a poster of the text of the treaty and 122 yellow “X”s on the fence, one for every nation that voted in favor of the treaty at the United Nations.
“January 22, 2021, will be a historic day for nuclear weapons,” according to a press release from Oak Ridge Environmental Peace Alliance, which has organized weekly and annual events opposing nuclear weapons for many years. “On that day, at midnight, the Treaty on the Prohibition of Nuclear Weapons enters into force, establishing in international law a categorical ban on nuclear weapons, seventy-five years after their development and first use.”

The Y-12 National Security Complex began a transition back to normal operations with as much telework as possible on Thursday, April 30.
It’s a staged transition. That means employees are being brought back incrementally, or in stages. That’s according to a response to questions provided by Kathryn King, spokesperson for Consolidated Nuclear Security, the plant’s managing and operating contractor.
A significant number of employees are teleworking, which means they are working remotely, King said.
Y-12 began limited operations on April 6 and transitioned to mission-critical operations on April 14 because of the COVID-19 global pandemic.
“But the prevalence of the virus in the community has steadily decreased as has the number of employees under quarantine because of a potential exposure to COVID-19,” King said.

A federal contractor violated nuclear safety requirements at the Y-12 National Security Complex, according to the National Nuclear Security Administration.
The violations are associated with the accumulations of uranium-235 in a glovebox, furnace, and casting line in Building 9212 at Y-12. The equipment is used to recover and process uranium-235, a fissile material that can be used in nuclear weapons and reactors.

The buildup of enriched uranium, discovered after hydraulic lines leaked in a glovebox, exceeded limits established by a safety program meant to help prevent a nuclear chain reaction.
An investigation of the uranium accumulations found weaknesses in five areas, according to the NNSA, which is part of the U.S. Department of Energy and overseas nuclear weapons work at sites like Y-12. Among the deficiencies were procedural compliances, evaluations of process changes, the analyses of causes, the establishment of roles and responsibilities, and the implementation of a program meant to prevent inadvertent accumulations.
“The National Nuclear Security Administration considers these deficiencies to be of high safety significance,” Administrator Lisa Gordon-Hagerty wrote in an April 6 letter. “Although there were no actual consequences to the public, workers, or the environment, these deficiencies eroded the barriers preventing a nuclear criticality and could, if left uncorrected, adversely impact nuclear and worker safety at the Y-12 National Security Complex.”
The letter was sent to Morgan Smith, president and chief executive officer of Consolidated Nuclear Security. CNS manages and operates Y-12, as well as the Pantex Plant near Amarillo, Texas, for the NNSA.

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.
