A reactor core that includes highly enriched uranium alloy components produced at the Y-12 National Security Complex in Oak Ridge could power future space exploration, including on the Moon and Mars, federal officials said.

The reactor core fabricated at Y-12 has been delivered to the Nevada National Security Site, where it is being used in a experiment called Kilopower. That’s a new power source that could provide safe, efficient energy for future robotic and human space exploration missions, according to the National Aeronautics and Space Administration, or NASA. The power source could help provide lighting, water, and oxygen on those missions.

NASA said the pioneering space power system, which would use nuclear fission, could provide up to 10 kilowatts of continuous electrical power for at least 10 years. That’s enough power to run two average households.

Four Kilopower units would provide enough power to establish an outpost, NASA said. The system could enable long-term stays on planetary surfaces.

Testing, which started in November, is being performed through this spring at the National Critical Experiments Research Center in the Device Assembly Facility at the Nevada National Security Site. [Read more…]

With some apparent exceptions, employees at the Y-12 National Security Complex in Oak Ridge will continue working even after the federal government shut down after federal funding expired Friday.

Y-12 posted an announcement after the federal government shut down early Saturday. The announcement said workers at Y-12 and the Pantex Plant in Amarillo, Texas, are expected to report to work on their next scheduled work day unless they have previously approved leave or have been given formal notice by their management to not report to work.

A few other federal organizations and federal contractors didn’t immediately appear to have posted notices as of early Saturday afternoon, about 12 hours after the shutdown began. Those include Oak Ridge National Laboratory. [Read more…]

The National Nuclear Security Administration will have an information session on Wednesday about the Y-12 National Security Complex, the Uranium Processing Facility construction project, and the work to replace the electrical substation at Y-12.

The information session was scheduled after Oak Ridge officials raised concerns in November and December about the power lines proposed on top of Pine Ridge as part of the electrical substation project. Pine Ridge separates Y-12 from the center of the city, and Oak Ridge officials have said they had not received adequate notice of the power line project and didn’t know what other options had been considered. They also expressed concerns about the lack of public input and the visual impact of building power lines and installing transmission towers on top of the ridge. As of December, Oak Ridge City Council members said they hadn’t seen a visual representation of what the power lines could look like. [Read more…]

The National Nuclear Security Administration has granted a 45-day discussion period for a project to build a new electrical substation at the Y-12 National Security Complex that could include logging work on top of Pine Ridge.

Oak Ridge officials had requested a 30-day delay of the logging work. City officials have raised concerns about that part of the project because they said they didn’t know about it until a week or two before logging operations were scheduled to start, there has been no public input, and cutting down trees and replacing them with transmission towers on top of the ridge would affect the view in that part of the city, including from two residential neighborhoods, Scarboro and Groves Park Commons. Pine Ridge is between Y-12 and the center of the city.

Oak Ridge officials have also said they don’t know what other options were considered, besides installing the high-voltage power lines on top of Pine Ridge.

The 161-kilovolt power lines will provide electricity to a new electrical substation that will service all of Y-12, but it is being built as a subproject of the Uranium Processing Facility. It would be near UPF on the west side of Y-12. UPF is the largest federal construction project in Tennessee since World War II, and it is expected to be completed by 2025 at a cost of no more than $6.5 billion.

Oak Ridge officials have emphasized that they support the project, but they don’t think the city has been treated as an equal partner on the electrical substation and power line portion of the project.

In a press release Tuesday, the City of Oak Ridge said the electrical substation project would involve clear-cutting 2.1 miles of mature trees along the top of Pine Ridge. The NNSA has delayed that project for 45 days, although some logging activity will still occur during that time. [Read more…]

The City of Oak Ridge has asked federal officials to consider an option that minimizes the impact of new high-voltage power lines planned on top of Pine Ridge, which is between the center of the city and the Y-12 National Security Complex.

The 161-kilovolt power lines will provide electricity to a new substation at the Y-12 National Security Complex. The new substation will service all of Y-12, but it is being built as a subproject of the Uranium Processing Facility. It would be near UPF on the west side of Y-12.

Dale Christenson, federal project director for the UPF, presented the project to Oak Ridge City Council during a November 7 work session. Less than a week later, at its November 13 meeting, City Council unanimously approved a letter that requested a postponement of tree-clearing work that is part of the project in order to discuss alternatives. The National Nuclear Security Administration agreed to a two-week delay, the City of Oak Ridge said in a press release Monday. Y-12 is an NNSA site.

In order to install the power lines, federal officials plan to remove trees and other vegetation from the top of Pine Ridge. The ridge is between Y-12 and two Oak Ridge neighborhoods: Scarboro and Groves Park Commons.

“Several weeks ago, the NNSA advised of proceeding with plans to clear cut 2.1 miles of mature trees and vegetation along the crest of Pine Ridge,” the city’s press release said. “More than 30 79-foot Tennessee Valley Authority transmission towers will be erected along the top of the ridge after clear cutting occurs. Although DOE has been planning this initiative for at least two years, the city has not been engaged in the process or studying electrical options for serving the new Uranium Processing Facility.” [Read more…]

Mercury contamination is one of the biggest problems remaining from the Cold War, U.S. Senator Lamar Alexander said during a groundbreaking ceremony on Monday morning. Alexander, a Tennessee Republican, first announced the new treatment facility at Y-12 more than four years ago.

“In May 2013, I came to Oak Ridge to announce that a new water treatment facility would be built at Y-12 at the head of the East Fork Poplar Creek to prevent mercury that was once used to make nuclear weapons from getting into our waterways,” Alexander said. “That day, I made a personal commitment to address one of the biggest problems we have from the Cold War era—mercury contamination—and help fund a solution. Today, I am proud to see that we are breaking ground on the new water treatment facility.”

Site preparation for the new Mercury Treatment Facility is expected to start this year, with the rest of construction beginning in late 2018. The facility is expected to start operating in late 2022.

The treatment plant will allow workers to demolish four large buildings where mercury, a toxic metal, was once used: Alpha 2, Alpha 4, Alpha 5, and Beta 4. Work on those buildings, mostly on the west side of Y-12, could start by 2024. [Read more…]

A letter unanimously approved by Oak Ridge City Council on Monday asks federal officials to postpone a project to remove trees and other vegetation from the top of Pine Ridge for 161-kilovolt power lines that will provide electricity to a new substation at the Y-12 National Security Complex.

Among the City Council concerns: They only recently learned of the project, they don’t know what other options were considered, and they are worried about the visual impact of 79-foot transmission towers being located on top of Pine Ridge. Also, Council members said, there has been no public discussion about the project until two weeks before the logging operation was scheduled to start on Thursday, November 16.

The clearing work is part of a project to build a new substation at Y-12. It will replace an existing substation that is “nearing the end of its service life,” according to information presented to City Council and some community members. The tree removal will allow the 161-kilovolt power lines to be installed in the cleared area. The area to be cleared is on top of the ridge, about 2.1 miles long, and it will support a right-of-way that is about 100 feet wide. The electrical line would run from east to west on Pine Ridge, according to a report to City Council from Oak Ridge City Manager Mark Watson. All of the work would be on U.S. Department of Energy property, officials said.

The new substation will service all of Y-12, but it is being built as a subproject of the Uranium Processing Facility. It would be near UPF on the west side of Y-12. [Read more…]

A groundbreaking has been scheduled for Monday morning for the Mercury Treatment Facility at the Y-12 National Security Complex.

Y-12 operations have historically used large amounts of mercury, and many of the buildings, now in varying states of deterioration, have mercury contamination, a media advisory said.

“The treatment facility will lower existing mercury levels from past releases and will serve as a guard against a potential increase in releases as mercury-contaminated buildings are demolished,” the media advisory said.

Deputy Energy Secretary Dan Brouillette will attend the groundbreaking, which is at Y-12 and not open to the public. U.S. Senator Lamar Alexander and U.S. Representative Chuck Fleischmann, both Tennessee Republicans, will also attend the groundbreaking, the media advisory said.

The groundbreaking is being presented by the U.S. Department of Energy and URS|CH2M Oak Ridge LLC, or UCOR, DOE’s cleanup contractor at federal sites in Oak Ridge. [Read more…]

With $3 billion in savings expected, not clear how much saved at Y-12, Pantex so far

More than $3 billion in savings are expected during a decade, but it’s not clear yet how much money has been saved after three years under a consolidated contract at two nuclear weapons plants in Tennessee and Texas.

The savings of $3.27 billion are expected under a contract that could last 10 years at the Y-12 National Security Complex in Oak Ridge, Tennessee, and Pantex Plant in Amarillo, Texas.

On Monday, officials said Consolidated Nuclear Security LLC, the contractor at the two sites, has generated significant savings in three fiscal years, although it’s not clear exactly how much they’ve saved. CNS has managed and operated Y-12 and Pantex Plant since July 1, 2014.

Federal officials announced the expected savings of $3.27 billion during a decade when the five-year contract was announced in January 2013. Officials said the consolidated contract, the result of years of work, could save money in part by eliminating redundancies in such areas as human resources, purchasing, finance, and information technology.

Two congressmen, one from East Tennessee and other the chair of the House Armed Services Committee, praised the consolidated contract that has been used to manage and operate the Pantex Plant in Amarillo, Texas, and the Y-12 National Security Complex in Oak Ridge for more than three years.

The two sites are managed by Consolidated Nuclear Security LLC. Y-12 and Pantex are involved in nuclear weapons work and nuclear nonproliferation, and providing enriched uranium for naval, research, and isotope production reactors.

The transition to the consolidated contract, one of the most complex in the history of the U.S. Department of Energy, was completed on July 1, 2014. At that time, officials said the contract included a total annual operating budget of $1.5 billion and employment of about 8,000 in Tennessee and Texas. [Read more…]

DOE, NNSA deny alleged risk of ‘catastrophic collapse’ of old Y-12 buildings

A low-level aerial shot of Building 9212 at the Y-12 National Security Complex, one of the buildings mentioned in a federal lawsuit filed in July over the proposed Uranium Processing Facility.

Note: This story was updated at 8:30 a.m.

The plaintiffs in a civil lawsuit filed in federal court in July alleged that there is a risk of a catastrophic collapse of old buildings containing nuclear weapon components at the Y-12 National Security Complex, possibly due to a large earthquake. A catastrophic collapse “would likely” result in the release of nuclear or toxic materials and place the environment and local residents in “extreme peril,” the plaintiffs said.

But federal officials denied that allegation and others in a response filed in late September.

The 44-page civil complaint, which is related to the planned Uranium Processing Facility at Y-12, was filed July 20 in U.S. District Court in Washington, D.C. The seven plaintiffs include three public interest organizations—Oak Ridge Environmental Peace Alliance, Nuclear Watch of New Mexico, and Natural Resources Defense Council of Washington, D.C.—and four people who live in Oak Ridge and Knoxville.

The federal lawsuit asked for an environmental review of the new design for the UPF, where design plans have changed from one building to three. The lawsuit alleged that the U.S. Department of Energy and the National Nuclear Security Administration have violated a federal environmental law, the National Environmental Policy Act, or NEPA, as they implement the major design change.

Specifically, the plaintiffs have requested a new supplemental environmental impact statement or a new site-wide environmental impact statement for the revised UPF design. They cited the decision to build several new buildings and the plan to continue using existing buildings that the plaintiffs say have significant structural defects. They want the U.S. District Court to vacate, or void, a supplement analysis and an amended record of decision prepared by the NNSA in 2016. [Read more…]
