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…]

After two decades, work was completed in December on a program to extend the life of the W76 nuclear warhead, the Y-12 National Security Complex said on Monday.

That ended a decade of work to extend the service life of the original warhead design by 40 years, Y-12 said.

“This warhead plays a vital role in maintaining the nation’s credible nuclear deterrent,” said Consolidated Nuclear Security LLC, which manages and operates Y-12 for the National Nuclear Security Administration.

The Life Extension Program, or LEP, is for the W76-1 warhead. The W76-1 is a refurbished W76-0 warhead. The W76-0 warhead is a submarine-launched ballistic missile system that was first introduced into the stockpile for the U.S. Navy in 1978. The warhead is deployed with Trident II D5 missiles on Ohio-class nuclear ballistic missile submarines. [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 partial shutdown of the federal government does not affect state oversight of the federal cleanup program in Oak Ridge, a state official said Thursday.

At this time, the federal shutdown has no impact on the Tennessee Department of Environment and Conservation, said Kim Schofinski, TDEC deputy communications director. That means state oversight of the Oak Ridge cleanup program is not currently affected. The Oak Ridge sites include East Tennessee Technology Park (the former K-25 site), Oak Ridge National Laboratory, and Y-12 National Security Complex. [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…]

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…]

Y-12 criticality alarms function properly in tests

Alarms designed to detect a nuclear criticality accident at the Y-12 National Security Complex have been tested, and the systems functioned appropriately and as required, the plant said in November.

Y-12 has had a criticality accident alarm system since 1945. A criticality accident would occur if there were an uncontrolled nuclear chain reaction. It could result in the release of radiation and significant exposures to nearby workers if the area were not immediately evacuated. It’s something that the plant takes steps to avoid. The alarms are designed to alert workers if there is an accident.

A nuclear criticality alarm at the 811-acre plant, which works on nuclear weapons components and stores highly enriched uranium, has been given credit for helping to save lives in a nuclear criticality accident in 1958. In that case, which was the first process criticality accident in the United States, Y-12 employees immediately evacuated when they heard the alarm.

A report published by Consolidated Nuclear Security, a federal contractor, said the basic design and electronic configuration of the older criticality alarm system installed in Y-12’s existing facilities, with the exception of the Highly Enriched Uranium Materials Facility, date back to 1957. The legacy system has received many upgrades since installation, and detector stations have been removed and relocated as enriched uranium operations have evolved, said the report, titled “Qualification of Y-12 Legacy Criticality Accident Alarm System Detectors.” [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…]
