More than 200 scientists from around the world met from Oct. 27 to 29, 2015, at the U.S. Department of Energy’s Oak Ridge National Laboratory to provide input on the scientific instruments that would be installed at a proposed Second Target Station, or STS, pictured above at center right at the Spallation Neutron Source.

The next decision about the second target station at the Spallation Neutron Source could be made later this year or in the first quarter of next year, U.S. Energy Secretary Dan Brouillette told a House subcommittee on Thursday. The next decision would include an alternative selection and a cost range.

The $1.4 billion SNS is located on Chestnut Ridge at Oak Ridge National Laboratory. It provides neutrons for research.

The second target station has been part of SNS plans for many years. It’s one of two upgrades being pursued at SNS. The other is a proton power upgrade, which is expected to double the power of SNS’s proton beam from 1.4 megawatts to 2.8 megawatts.

The second target station has a current estimated cost range of $800 million to $1.5 billion. The U.S. Department of Energy said the second target is needed more than a decade ago, in January 2009. The second target station would use a narrow proton beam and a compact, rotating, water-cooled tungsten target. It is expected to fill gaps in materials research that require the combined use of intense, cold (longer wavelength) neutrons and instruments that can help analyze complex materials. It could have up to 22 experimental beamlines.

President Donald J. Trump formally nominated Dan Brouillette to serve as the next energy secretary on Thursday.

Brouillette, a former Ford executive, is currently deputy secretary in the U.S. Department of Energy. If confirmed by the U.S. Senate, he would replace Rick Perry, who is resigning as energy secretary.

“I am honored to be nominated by President Trump to serve as the U.S. secretary of energy, and grateful to Secretary Perry for asking me to join him at the Department of Energy over two years ago,” Brouillette said in a DOE press release on Thursday. “If confirmed, I will further Secretary Perry’s legacy of promoting energy independence, innovation, and security for the American people.”

Brouillette has visited DOE sites in Oak Ridge as deputy secretary, while Perry has visited as energy secretary, including to announce Frontier, a new supercomputer at Oak Ridge National Laboratory, in May.

U.S. Deputy Secretary of Energy Dan Brouillette traveled to Tennessee this week to tour the BWXT-Nuclear Fuel Services Inc. Facility and Oak Ridge National Laboratory, and meet with University of Tennessee President Randy Boyd.

Brouillette was joined by Congressman Phil Roe and BWXT-Nuclear Fuel Services leadership on his tour of the downblending process facility and the fuel manufacturing facility at NFS, a U.S. Department of Energy press release said.

“They had a productive discussion about the innovative technologies pioneered by BWXT and NFS that fuel our nation’s naval reactors and defense industry,” the press release said. “The deputy secretary emphasized the importance of the critical work being done at this facility.”

Federal officials have authorized the start of construction of the three main buildings, including one for enriched uranium operations, at the Uranium Processing Facility at the Y-12 National Security Complex in Oak Ridge. It’s the largest federal construction project in Tennessee since World War II.

The authorization was announced Friday by the National Nuclear Security Administration, which is part of the U.S. Department of Energy. Y-12 is an NNSA site.

The authorization came from DOE leadership, NNSA said in a press release on Friday. The authorization allows the NNSA to start construction on the Main Process Building, Salvage and Accountability Building, and Process Support Facilities subprojects, the press release said.

UPF will replace an early-Cold War plant with a modern, more efficient, and safer facility for conducting highly-enriched uranium operations at Y-12, the NNSA said. Federal officials have been saying for a while that the facility is expected to be completed by 2025 at a cost of no more than $6.5 billion. [Read more…]

Treatment facility will reduce mercury in creek water, allow cleanup work at Y-12

The new Mercury Treatment Facility at the Y-12 National Security Complex will help reduce the amount of mercury that gets into East Fork Poplar Creek and allow the demolition of four large buildings where mercury was used to help make nuclear weapons during the Cold War, officials said Monday.

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…]

Groundbreaking scheduled for Mercury Treatment Facility at Y-12

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…]
