A second employee at the Y-12 National Security Complex in Oak Ridge has tested positive for COVID-19.

Consolidated Nuclear Security, the federal contractor that manages and operates the nuclear weapons production plant, said it learned of the positive test result on Friday.

The second employee is from the same work area as the first employee who tested positive, CNS said Friday night. CNS confirmed the first case on Monday.

The second employee was quarantined earlier this week and remains in isolation at home, and the affected work locations were disinfected earlier this week, CNS said Friday.

A federal contractor is limiting the number of employees who can ride a bus at one time to the Uranium Processing Facility construction site at the Y-12 National Security Complex and started the process of staggering shifts at the project to help keep workers separated from each other as the world tries to slow the spread of COVID-19, a contagious respiratory illness that can be deadly.

The changes at Y-12 were disclosed on Wednesday by the plant operator, Consolidated Nuclear Security, in response to questions from Oak Ridge Today after a plant employee tested positive for COVID-19 on Monday.

Oak Ridge Today had asked about construction workers being bused to the Uranium Processing Facility construction site from the east side of Y-12 each morning and whether the confirmation of a COVID-19 case at the 811-acre plant would affect those construction bus rides, including by possibly requiring employees to have some physical separation on the bus rides.

The Consolidated Nuclear Security employee who tested positive for COVID-19 on Monday left work at the Y-12 National Security Complex after becoming ill on Thursday, March 19.

In response to questions on Wednesday, CNS did not say where the employee worked at Y-12 or if they know how the worker was infected.

CNS said the employee has been isolated at home after receiving the positive COVID-19 test result, and the plant’s medical staff are coordinating with the Tennessee Department of Health.

“The employee’s work location was disinfected along with all other locations the employee is known to have visited,” CNS said. “The employee’s activities were reviewed, and everyone who is known to have come into direct contact with the employee in the two days prior to the development of symptoms is being contacted and asked to self-quarantine for 14 days, per the Centers for Disease Control and Prevention’s (CDC) guidelines.”

No confirmed COVID-19 cases have been reported at two nuclear weapons production sites in Tennessee and Texas, a federal contractor said Wednesday. The two sites are the Y-12 National Security Complex in Oak Ridge, Tennessee, and Pantex Plant near Amarillo, Texas.

At Y-12, the contagious respiratory illness has not affected operations or construction projects such as the Uranium Processing Facility, according to Consolidated Nuclear Security, the contractor that manages and operates the two sites.

CNS said it is increasing sanitation efforts, limiting travel and visits, minimizing external visitors, and increasing the use of technology to limit face-to-face contact.

Federal officials have approved the need for a new Lithium Production Facility at the Y-12 National Security Complex, and in May 2018, they said it could be built on the east side of the 811-acre plant, possibly where the Biology Complex, the brick building at center, is now.

The proposed Lithium Processing Facility at the Y-12 National Security Complex could cost between $955 million and $1.65 billion, and it could be completed in 2031, the National Nuclear Security Administration said Thursday.

The Lithium Processing Facility could be built where the former Biology Complex is located on the east side of Y-12. That’s the NNSA’s preferred site. The Biology Complex is being prepared for demolition by the U.S. Department of Energy’s Office of Environmental Management.

On Thursday, the NNSA, which is part of the U.S. Department of Energy, said it had approved the conceptual design and cost range for the proposed 134,000-square-foot Lithium Processing Facility.

The facility will replace Y-12’s current lithium processing operations, which are located in a World War II-era building. That building, Building 9204-2, or Beta 2, has had materials fall from the ceiling, including chunks of concrete that reportedly weighed up to 200 pounds. The falling materials and concerns about worker safety have been cited by federal officials during congressional hearings in Washington, D.C.

The Roane State Foundation has won a $6,000 grant from the CNS Y-12 Community Investment Fund to help adult students in the community college’s programs in computer science, cybersecurity, and mechatronics, a press release said.

CNS operates the Y-12 National Security Complex in Oak Ridge, and the contractor established the fund through the East Tennessee Foundation in 2014 as part of its commitment to Oak Ridge and the surrounding communities.

Officials said the grant will fund scholarships to help students pay for industry-recognized certifications. Those certifications are important tools for graduates to pair with their college degree to demonstrate to employers they have the skills and documentations that often allow graduates to earn higher wages when going to work, the press release said.

Note This story was last updated at 9:38 a.m. Sept. 25.

A federal judge in Knoxville on Tuesday said a critical decision made in 2016 for enriched uranium operations at the Y-12 National Security Complex, including for the $6.5 billion Uranium Processing Facility, violated a national environmental law, and she ordered the decision vacated, or set aside.

The UPF is already under construction, and Wedenesday morning, the National Nuclear Security Administration, which oversees work at Y-12, said construction will continue.

The 104-page opinion and order was filed in U.S. District Court on Tuesday by Chief U.S. District Judge Pamela L. Reeves.

One of the plaintiffs said the decision to vacate the amended record of decision published in the Federal Register in 2016 means the NNSA no longer has the legal authority to continue construction work at UPF.

But the NNSA said it was pleased that the court’s memorandum opinion rejected almost all of the plaintiff’s claims regarding National Environmental Policy Act violations related to UPF construction.

“However, with the court agreeing that there was inadequate consideration of new information concerning seismic hazards at Y-12, NNSA will review the seismic analysis while conferring with the Department of Justice on the possibility of appeal,” the NNSA said. “In the meantime, construction of UPF will proceed.”

Besides the amended record of decision, Reeves said supplement analyses prepared in 2016 and 2018 also violated the National Environmental Policy Act, or NEPA, and she said they were to be set aside as well.

The National Nuclear Security Administration has signed a $600 million contract with Cray Inc. to build the first exascale supercomputer for the NNSA at Lawrence Livermore National Laboratory in California.

It is one of three exascale systems to be built at U.S. Department of Energy or NNSA laboratories. The other two exascale machines will be at DOE laboratories: Aurora at Argonne National Laboratory near Chicago and Frontier at Oak Ridge National Laboratory.

ORNL currently has the most powerful supercomputer in the world, Summit, and LLNL has the second-fastest, Sierra. They are both petaflop systems. Summit is capable of 200 petaflops, or 200,000 trillion calculations per second.

All three of the new exascale supercomputers will be built by Cray using their Shasta architecture, Slingshot interconnect, and new system software platform, the NNSA said in a press release Tuesday.

An exascale computer will be able to solve calculations up to 50 times faster than today’s top supercomputers, exceeding a quintillion, or 1018, calculations per second. That’s a billion billion calculations per second.

Note: This story was updated at 5:30 p.m.

The Y-12 National Security Complex in Oak Ridge is supporting a program to make an isotope used in more than 40,000 medical procedures across the nation each day. The goal is to produce the isotope, molybdenum-99 (Mo-99), in the United States without using highly enriched uranium.

Some of that work could occur in Oak Ridge. A company called Coquí Radio Pharmaceuticals Corporation announced in April that it plans to build a $500 million medical isotope production facility at the Heritage Center in west Oak Ridge. Coquí’s facility would make medical isotopes, primarily Mo-99, and the company could start production in 2025.

In a video posted online, Y-12 said some of its researchers have extensive knowledge of Mo-99 and are sharing that information with Coquí and other companies hoping to produce the isotope.

Y-12 has been involved with Mo-99 since 2009, said Cole Jackson of Y-12 Global Security and Strategic Partnerships.

No injuries were reported during a fire at a transformer for a salt bath used to heat depleted uranium at the Y-12 National Security Complex in May.

The transformer fire was reported Monday, May 20, in Building 9215 at Y-12. It burned no more than about 25 minutes, according to the Defense Nuclear Facilities Safety Board. No depleted uranium was being processed at the time of the fire, the board said.

The salt bath heats depleted uranium before metalworking operations.

The DNFSB said the system engineer had stepped away from the salt bath while it was slowly heating to a new temperature, and he noticed the fire after re-entering the area after a supervisor told him about an unusual odor, the DNFSB said. The engineer called 911, and all personnel evacuated the immediate area.
