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…]

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 City of Oak Ridge held ceremonial groundbreakings on Monday, January 14, to celebrate the start of two major projects: the new Oak Ridge Preschool with Scarboro Park improvements and the new Oak Ridge Senior Center. Construction activity is already under way at both sites, and the buildings are slated for completion later this year.

“These projects have been in the planning stages for decades and we are making good on promises to deliver them,” Oak Ridge Mayor Warren Gooch said in a press release. “The Preschool and the Senior Center will have a positive impact on our citizens and their families for generations to come. We are excited to see construction begin.”

Studio Four Design Inc. was chosen to design the Preschool and the Senior Center. At a special meeting in October 2018, Oak Ridge City Council unanimously approved resolutions awarding construction contracts to Jenkins and Stiles LLC totaling just more than $11 million ($8.4 million for the new Preschool and Scarboro Park improvements and $2.68 million for the new Senior Center). General obligation bonds were sold in late November to completely fund the projects.

“After years of discussion, plans for these important facilities are coming to fruition,” Oak Ridge City Manager Mark Watson said in the press release. “The Preschool and Senior Center are welcome additions to our community. We are appreciative of all the hard work that has gone into making these amenities a reality for Oak Ridge.” [Read more…]

Council approves plan for apartments at former AMSE site

The Oak Ridge Municipal Planning Commission will consider a rezoning and planned unit development on Thursday, Dec. 20, 2018, that would allow apartments to be built on the former American Museum of Science and Energy property on South Tulane Avenue.

The Oak Ridge City Council approved a rezoning and planned unit development on Monday, Jan. 14, 2019, that would allow apartments to be built on the former American Museum of Science and Energy property on South Tulane Avenue.

 

The Oak Ridge City Council on Monday approved a plan that would allow apartments at the former American Museum of Science and Energy site on South Tulane Avenue.

The apartment proposal requires a rezoning and the approval of a plan for a planned unit development, or PUD.

They were approved in a 5-1-1 vote in the first of two readings on Monday. The second and final reading will presumably be in February.

Voting for the plan were Oak Ridge Mayor Warren Gooch and City Council members Kelly Callison, Jim Dodson, Derrick Hammond, and Ellen Smith. [Read more…]

Council rejects revised plan for Main Street Oak Ridge

Note: This story was last updated at 1 a.m.

The Oak Ridge City Council on Monday narrowly rejected a revised plan that would have allowed four national retailers to build stores at Main Street Oak Ridge.

The Council had unanimously approved a revised plan for Main Street Oak Ridge, subject to certain conditions, in December. That was the first of two readings.

But Council rejected the plan in a 4-3 vote in the second and final reading on Monday.

The rejection hinged on concerns that included the closure of an access road to the 58-acre site, the movement of mixed-use areas to a future phase along Wilson Street, and questions about whether there are other site plan options and whether the development would or should establish a “city center.” People who rejected the revised plan or asked Council to reject it said they support the development and want continued negotiations with RealtyLink, the developer. But it wasn’t immediately clear this week if that will happen.

Those who had supported the revised plan, on the other hand, warned that rejecting it could affect funding for Oak Ridge and Anderson County governments and school systems by diminishing expected sales and property tax revenues, possibly in the range of several hundred thousand dollars. They worried about the impact on the city’s retail community, property tax values, and new housing developments. They called the project a “once in a generation” opportunity and said it could be a few decades before another similar proposal emerges.

It’s not clear what will happen next or if there is any solution that will be acceptable to both RealtyLink and the planning commissioners and City Council members who opposed the revised plan. On Tuesday, three people involved in the project, including RealtyLink, said there is no other design, no “plan B.”

“We’ve worked for six months to get to where we are,” said Neil Wilson, principal of RealtyLink in Greenville, South Carolina. “We didn’t get what we wanted, and they didn’t get what they wanted.”

He said the four national tenants were notified Tuesday that Council rejected the proposed changes to the planned unit development for Main Street Oak Ridge. The potential tenants will be notified if something changes. [Read more…]

The City of Oak Ridge will hold ceremonial groundbreakings on Monday, January 14, to celebrate the start of two major projects: the new Oak Ridge Preschool with Scarboro Park improvements and the new Oak Ridge Senior Center. Construction activity is already under way at both locations.

Studio Four Design Inc. of Knoxville was chosen to design the both the Preschool and the Senior Center. At a special meeting on October 11, Oak Ridge City Council unanimously approved resolutions awarding construction contracts to Jenkins and Stiles LLC.

The new preschool will be a single-story facility of about 33,000 square feet located on Carver Avenue. The build site is inside Scarboro Park, a roughly 10-acre parcel. The project includes improvements to the adjacent park area such as lighted basketball/tennis courts, a baseball field, a public pavilion, green space, and a walking trail. [Read more…]

The design is complete and funding is available for the construction of an Equipment Building and Viewing Tower that will help commemorate the history of the K-25 Building, once the world’s largest building under one roof.

K-25 was built in Oak Ridge during World War II to help enrich uranium for the Manhattan Project. That was a top-secret federal program to build the world’s first atomic weapons. During the war, Oak Ridge enriched the uranium for “Little Boy,” the first atomic bomb used in wartime. “Little Boy” was detonated over Hiroshima, Japan, on August 6, 1945, shortly before the end of World War II.

After the war, the four-story, 44-acre K-25 Building and four other large buildings at the K-25 site continued to use a process known as gaseous diffusion to enrich uranium for atomic weapons and commercial nuclear power plants. Officials say the K-25 site, which is in west Oak Ridge, helped win the Cold War.

After decades of use, the K-25 site was shut down in the mid-1980s, and as part of a cleanup effort in recent years, the five large gaseous diffusion buildings have been demolished. But the history of the K-25 building and the site will live on in a History Center on the second floor of Oak Ridge Fire Station Number 4, which is next to K-25’s concrete slab, and at the Equipment Building and Viewing Tower, which will be just west of the History Center.

The History Center, Equipment Building, and Viewing Tower will be on the south side of the former K-25 Building. The site is now known as Heritage Center or East Tennessee Technology Park. [Read more…]

The National Oceanic and Atmospheric Administration building in Oak Ridge is closed due to the partial shutdown of the federal government, which is now three weeks old and approaching a record length.

NOAA is part of the U.S. Department of Commerce, which is one of nine cabinet-level departments affected by the partial government shutdown. The shutdown, which mostly hinges on a dispute between President Donald Trump and Democrats in Congress over whether to allocate $5.7 billion in funding for a wall on the border with Mexico, also affects the Environmental Protection Agency, Food and Drug Administration, National Aeronautics and Space Administration, the federal judiciary, and other related government programs.

About 380,000 workers were to be sent home and not be paid for their time off during the shutdown, the New York Times reported. Another 420,000 deemed too essential to be furloughed are being forced to work without pay, the newspaper said. After past shutdowns, such workers have been reimbursed later.

It wasn’t immediately clear Friday afternoon how many NOAA workers in Oak Ridge, part of an air research laboratory that has a division here, have been furloughed and how many, if any, are being forced to work without pay. A sign posted on the front door announced that the building is closed due to the shutdown. [Read more…]

Oak Ridge National Laboratory is adding a three-story office and laboratory building on its central campus.

It would be the first time a building of this size has been added at ORNL since the Chemical and Materials Science building (Building 4100) was completed in 2011, spokesperson Morgan McCorkle said in a response to questions Thursday.

She said the new building will be located in the central part of the main ORNL campus between buildings 3500 and 3525.

“The facility will offer state-of-the-art laboratory space and offices to support a range of research activities, including growing missions in computing and materials science and development,” McCorkle said. “The space can be adapted to serve the needs of changing scientific programs and priorities.” [Read more…]

Tennessee officials have approved the demolition of two large buildings at the Biology Complex at the Y-12 National Security Complex.

The Biology Complex once housed more people with doctorates than anywhere in the world, according to the U.S. Department of Energy. DOE has said the men and women who worked there radically enhanced the world’s knowledge in biology, including the discovery of the Y chromosome.

Y-12 announced in December that the Tennessee Historical Commission had approved the demolition of the two buildings: Buildings 9207 and 9210. The buildings date back to the Manhattan Project, a top-secret federal program to build the world’s first atomic weapons during World War II. Oak Ridge was part of that project.

The demolition work at the Biology Complex is being overseen by the U.S. Department of Energy’s Oak Ridge Office of Environmental Management. [Read more…]

The Y-12 National Security Complex in Oak Ridge manufactured the uranium reactor core for a federal experiment that tested whether a nuclear energy source could provide power for space exploration.

“The full-power run showed that it may be feasible for NASA to use small fission reactors for deep space exploration and manned missions to the moon and Mars,” the National Nuclear Security Administration said in May.

The NNSA, which is part of the U.S. Department of Energy, worked with NASA (the National Aeronautics and Space Administration) on the project. It’s nicknamed KRUSTY, an acronym for Kilowatt Reactor Using Stirling Technology.

“In a joint venture with NASA last year, NNSA completed final design, fabrication, and full-power testing of a nuclear criticality experiment that can be used for a manned lunar or Mars space mission,” NNSA Administrator Lisa Gordon-Hagerty said in a post published on Twitter on Friday.

The uranium reactor core from Y-12 was delivered to the National Criticality Experiments Research Center at the Nevada National Security Site in the fall of 2017. [Read more…]

A vehicular homicide case that started with a fatal traffic crash in Oak Ridge ended when the defendant died.

The case against Vickie Gay Gilmore, 64, had been pending in Anderson County Criminal Court in Clinton. In July, another evaluation was ordered at the Moccasin Bend Mental Health Institute in Chattanooga. Gilmore was to be evaluated for her competency to stand trial and her mental condition at the time of the crime (the insanity defense). She had been found to be capable of adequately helping in her defense in an earlier evaluation at Moccasin Bend in 2016, but a later evaluation by a doctor produced contrary findings, according to an April 2018 order for a new competency evaluation.

The new evaluation order in July was stayed, or delayed, in September because of Gilmore’s deteriorating health and her inability to travel.

The charges against her were dismissed in a judgement dated October 9 and filed in November. [Read more…]
