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.

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 reported in transformer fire at salt bath for depleted uranium

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.

Almost 700 kilograms of highly enriched uranium has been moved from the United Kingdom to the United States, and the material is being securely stored at the Y-12 National Security Complex in Oak Ridge for now, federal officials said.

The National Nuclear Security Administration said this month that the highly enriched uranium, or HEU, will be down-blended later into low enriched uranium for use as nuclear reactor fuel.

“The material was returned to Y-12 for secure storage awaiting future disposition,” the NNSA said in a statement provided Friday by Steven Wyatt of the NNSA Production Office in Oak Ridge.

Wyatt said Y-12 supported the removal effort, which was announced by the NNSA on May 3, through technical oversight and guidance of the processing and packaging of material.

The U.S. Department of Energy is updating a classified security order that will reflect recent intelligence assessments about the threats posed by unmanned aerial systems, or drones, as some federal officials express concerns that terrorists could use drones to harm the United States.

That information is included in a report issued by the DOE Inspector General, or IG, in April.

While developing the report, the IG reviewed controls in place at the Y-12 National Security Complex and Idaho National Laboratory. The IG found that the National Nuclear Security Administration, including Y-12, has been proactive in establishing “limited internal controls” that include observing and reporting unmanned aerial systems, as well as using deadly force if hostile intent is determined.

The IG said drones are becoming increasingly popular, and some unmanned aerial systems that are commercially available and relatively affordable have high-definition cameras, auto pilot global positioning system navigation, and the ability to carry and remotely release payloads.

A new class of workers at the Y-12 National Security Complex has been added to a federal energy employees compensation program that was established about two decades ago, officials announced Thursday.

The affected employees would have worked at Y-12 between January 1, 1958, and December 31, 1976. They would have been employees of the U.S. Department of Energy, its predecessor agencies, or their contractors and subcontractors. They would have had an aggregate of at least 250 work days. That could have occurred either only through this employment or in combination with work days that meet the parameters established for one or more other classes of employees in what is known as the Special Exposure Cohort.

The notice that the new class of employees has been added to the Special Exposure Cohort was published in the Federal Register by the Centers for Disease Control and Prevention on Thursday. Oak Ridge Today reported in December that the class was being evaluated, based on exposure to radiation from thorium metal parts and plutonium-241 isotopes, and reported in March that the U.S. Department of Health and Human Services had designated the class of employees to be added. The new designation became effective March 28.

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…]

Contributions to the United Way from the Y-12 National Security Complex in Oak Ridge and Pantex Plant in Amarillo, Texas, topped $1 million in 2018. The donations were collected from employees and retirees, according to Consolidated Nuclear Security LLC, which manages and operates the two sites.

The sites engaged in year-long campaigns to generate money for the United Way, raising funds through silent auctions and various jewelry, book, and food sales at the sites as well as employee contributions, CNS said in a press release. A $150,000 donation from the parent companies of CNS was also included in the total.

“One of the best ways to help our local communities is through the United Way,” Y-12 Site Manager Bill Tindal said. “Y-12 and East Tennessee are special places because of the commitment of our employees to giving back to our neighbors.” [Read more…]

Watts Bar Nuclear Plant

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.

Image from “Final Long-Term Management and Storage of Elemental Mercury Supplemental Environmental Impact Statement” published by U.S. Department of Energy in September 2013.

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.
