Chris Borum, for more than 16 years a security guard at the Y-12 National Security Complex in Oak Ridge, said it was time for a change.

As the years passed, he worried he might not be able to meet rigorous annual physical qualifications for his job at the nuclear weapons facility.

Borum, a Kingston resident, said he wanted to stay at Y-12 and eventually retire from there, “but I wanted to leave on my own terms.”

So when a job posting for a material handler was posted on the Y-12’s Intranet, he went for it. [Read more…]

The U.S. Nuclear Regulatory Commission announced on Monday that there would be no significant impact from producing tritium for nuclear weapons in a second unit at the Watts Bar Nuclear Power Plant in Rhea County.

The project involves the Y-12 National Security Complex in Oak Ridge.

The tritium could be produced in Unit 2 at Watts Bar, which is near Spring City about 45 miles southwest of Oak Ridge.

Tritium, which boosts the yields of nuclear weapons, is already being produced in Watts Bar Unit 1. The Tennessee Valley Authority has been producing tritium there since 2003.

The U.S. Department of Energy is considering whether to lease space to store elemental mercury from sites across the country.

The facility could store about 1,200 metric tons (1,300 tons) of elemental mercury. The waste has been generated at sites in the United States, mostly at gold mining operations, according to the DOE Office of Environmental Management.

The mercury that could be stored at the leased facility is separate from the 1,200 metric tons of mercury stored at the Y-12 National Security Complex in Oak Ridge. The Y-12 mercury, about 2.6 million pounds stored in seamless steel flasks, was acquired for lithium-6 isotope separation operations for thermonuclear weapons.

Three national laboratories, including Oak Ridge National Laboratory, are building new computer systems that could be many times more powerful than today’s top supercomputers.

The new machines are exascale systems. None have been delivered yet, but the planning for them started more than a year ago and the new high-performance systems could be delivered to the three laboratories in the next several years. Planning for the exascale computers was under way even before the world’s most powerful supercomputer, a petaflop system called Summit at ORNL, was unveiled in June 2018.

Exascale computers could be 50 to 100 more powerful than today’s petaflop computers, according to the U.S. Department of Energy. Besides ORNL, they could be located at Argonne National Laboratory southwest of Chicago and Lawrence Livermore National Laboratory east of San Francisco. The first system is expected at Argonne, followed by a second system at ORNL.

U.S. nuclear forces could cost about $494 billion during a 10-year period if current plans are followed, according to the nonpartisan Congressional Budget Office.

The CBO is required by law to estimate the 10-year costs every two years. The new estimate is $494 billion for work between 2019 to 2028, the CBO said in a report published this month. That’s an average of just under $50 billion a year.

The Y-12 National Security Complex in Oak Ridge participates in the nuclear weapons work along with other U.S. Department of Energy sites and the U.S. Department of Defense.

The CBO said nuclear weapons have been an important part of U.S. national security since they were developed during World War II. Oak Ridge was the main production site for the top-secret project to build those first weapons, and Y-12 continues to work on nuclear weapons. One modernization program for the W76-1 warhead was recently completed, and another for the B61-12 bomb has started.

The CBO said nuclear forces were central to U.S. defense policy during the Cold War, and a large arsenal was built. [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…]

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…]

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…]

The U.S. Department of Energy is not affected by the partial government shutdown that started at midnight, and DOE employees and contractors, including in Oak Ridge, are expected to continue their normal work schedules.

”The partial government shutdown does not impact Department of Energy facilities,” federal officials said in a statement. “DOE’s fiscal year 2019 appropriations bill was approved by Congress and signed by the president in September. DOE employees and contractors are expected to continue to report to work according to their usual work schedule.”

Among the DOE sites and operations in Oak Ridge are East Tennessee Technology Park, Oak Ridge Institute for Science and Education, Oak Ridge National Laboratory, Oak Ridge Office, Oak Ridge Office of Environmental Management, Office of Scientific and Technical Information, and Y-12 National Security Complex. Y-12 is overseen by the National Nuclear Security Administration, a DOE agency. [Read more…]

Updated: Park Service will not provide visitor services during shutdown

The National Park Service will not provide visitor services during the partial government shutdown that started Friday night, and that could affect programs in Oak Ridge and other national parks in the area. But Manhattan Project Park locations at three sites, including Oak Ridge, will remain open to the public and continue to provide visitor services.

Oak Ridge is part of the Manhattan Project National Historical Park, which is part of the National Park Service. The park, which is about three years old, commemorates the Manhattan Project, a top-secret federal program to build the world’s first atomic weapons during World War II. Besides Oak Ridge, two other sites are part of the park: Hanford, Washington, and Los Alamos, New Mexico.

In Oak Ridge, the Manhattan Project National Historical Park is based at the Children’s Museum on West Outer Drive. The park includes programs such as historical films, celebrations, and programs, and informative hikes and bicycle rides with rangers.

The National Park Service did not respond to two inquiries this week, but a program scheduled for Saturday afternoon in Oak Ridge will presumably be canceled. That program was intended to discuss secrecy, security, and spies during the Manhattan Project. It was scheduled for this afternoon (Saturday, December 22) at the Turnpike Gatehouse in west Oak Ridge. [Read more…]
