The Oak Ridge Site Specific Advisory Board on Wednesday will hear about work by the U.S. Department of Energy’s Oak Ridge Office of Environmental Management to ensure there is sufficient waste disposal capacity to complete future cleanup work at Oak Ridge National Laboratory and Y-12 National Security Complex.

DOE is considering a new landfill known as the Environmental Management Disposal Facility. It could be built in central Bear Creek Valley west of Y-12. There was a public meeting to discuss the project at the New Hope Center at Y-12 on Wednesday, November 7.

The existing landfill, the Environmental Management Waste Management Facility west of Y-12, is about three-quarters full, and it is expected to fill up in the early 2020s after cleanup work is complete at the East Tennessee Technology Park, the former K-25 site. [Read more…]

The 200-petaflop Summit supercomputer at Oak Ridge National Laboratory stayed at number one on the semiannual TOP500 list of the world’s most powerful supercomputers released Monday.

The Sierra supercomputer at Lawrence Livermore National Laboratory in Livermore, California, climbed to number two from number three. That means the United States now has the top two systems in the world, a position that China held a year ago.

Summit, a water-cooled IBM-built supercomputer, debuted at number one on the TOP500 list in June. That was the first time since 2012 that the United States had the most powerful supercomputer in the world. The earlier top system, Titan, a Cray machine, is also located at ONRL. ORNL and LLNL are both U.S. Department of Energy laboratories.

Officials celebrated the launch of Summit in a ceremony attended by U.S. Energy Secretary Rick Perry on June 8. The supercomputer is capable of 200 petaflops, or 200,000 trillion calculations per second. That makes it about about eight times more powerful than Titan, its predecessor.

Besides being the most powerful, Summit has been described as the world’s smartest supercomputer, a machine that can learn. As big as two tennis courts, Summit has 4,608 compute servers. Each has two 22-core IBM Power9 central processing units (CPUs) and six NVIDIA Tesla V100 graphics processing unit (GPU) accelerators. That’s more than 9,000 conventional processors and nearly 28,000 graphics processors, or about 37,000 total. [Read more…]

Researchers at Oak Ridge National Laboratory have demonstrated a 120-kilowatt wireless charging system for vehicles—providing six times the power of previous ORNL technology and a big step toward charging times that rival the speed and convenience of a gas station fill-up.

The wireless system transfers 120 kilowatts of power with 97 percent efficiency, which is comparable to conventional, wired high-power fast chargers. In the laboratory demonstration, power was transferred across a six-inch air gap between two magnetic coils and charged a battery pack.

ORNL researchers created and demonstrated the world’s first 20-kilowatt wireless charging system, which is being modified for applications such as commercial delivery trucks.

“It was important to maintain the same or smaller footprint as the previous demonstration to encourage commercial adoption,” said project lead Veda Galigekere of ORNL’s Power Electronics and Electric Machinery Group. [Read more…]

There is a public availability session on the proposed federal landfill in Oak Ridge on Thursday.

The U.S. Department of Energy has issued a proposed plan to build a new landfill on the Oak Ridge Reservation. The landfill, the Environmental Management Disposal Facility, would be in Bear Creek Valley west of the Y-12 National Security Complex. It is intended for disposal of radioactive, hazardous, and toxic wastes. It would be used as cleanup work ends at the East Tennessee Technology Park and the existing landfill, the Environmental Management Waste Management Facility fills up, and cleanup work moves to Y-12 and Oak Ridge National Laboratory.

A press release said the Sierra Club has invited state and federal officials from DOE, Environmental Protection Agency, and Tennessee Department of Environment and Conservation to be available for public questions about the Environmental Management Disposal Facility. The public availability session has been scheduled from 2 to 8 p.m. Thursday, October 11, at the TDEC office at 761 Emory Valley Road in Oak Ridge. [Read more…]

Centrus Energy Corporation has a $15 million project to prepare K-1600, a building in the middle of the historic K-25 “footprint,” for demolition.

On Tuesday, Centrus announced that it had received a work authorization from the U.S. Department of Energy for decontamination and decommissioning (D&D) work at the building. The work will include removing and disposing of equipment and materials to make K-1600 non-radiologically contaminated and non-possessing (i.e. unclassified), a press release said. The work will occur between October 1, 2018, and September 30, 2019.

After the work is completed, DOE will be able to turn over K-1600 to a contractor to demolish it, the press release said. It’s one of the last remaining “legacy structures” on the 2,200-acre site of the World War II-era K-25 uranium enrichment plant, now known as the East Tennessee Technology Park, the press release said.

Many other buildings have been demolished there, including the five large gaseous diffusion buildings once used to enrich uranium for atomic weapons and commercial nuclear power plants. ETTP is now being converted into a large industrial park in west Oak Ridge. [Read more…]

For the U.S. military, accurate weather prediction is vital to both the planning and execution of worldwide missions. To extend its weather modeling capabilities, the U.S. Air Force has joined the computing experts at the U.S. Department of Energy’s Oak Ridge National Laboratory in a strategic collaboration that includes procurement and operation of a new high-performance weather modeling computer system. Key members of the Air Force and ORNL teams, including computing and global security team members, gathered on July 10 to kick off this project and tour the facilities supporting the new system, according to a story posted by ORNL.

The Air Force 557th Weather Wing provides the Air Force and Army with global- and regional-level numerical weather model forecasts. With the increasing scale of the requirements for the new system, the Air Force and ORNL identified an opportunity to take advantage of the capabilities of ORNL’s National Center for Computational Sciences—including expertise in high-performance computing facilities and infrastructure, systems administration, computing procurement and acquisition, and system operations, the story said.

“We learned about the Air Force’s needs, and it was immediately clear that ORNL could help them solve their problems,” said Jim Rogers, NCCS director of computing and facilities. “We can integrate the Air Force weather team’s needs into our facilities in a cost-effective way, leveraging our capabilities to deliver exceedingly high availability to support their mission.” [Read more…]

Cyber security: Company will use ORNL random number generator for encryption

A company called Qrypt Inc. will incorporate a quantum random number generator developed by Oak Ridge National Laboratory into existing encryption techniques, strengthening cyber security, a press release said.

Qrypt has exclusively licensed the technology from ORNL, a U.S. Department of Energy laboratory. It’s intended to help defend against cyber attacks, including those posed by quantum computing.

Encryption uses codes or mathematical algorithms to make information such as messages or stored data unintelligible to unauthorized readers. Quantum computers make use of the quantum states of electrons or other particles to store and process information as quantum bits.

The press release said Qrypt will incorporate ORNL’s quantum random number generator into the company’s existing encryption platform. It will use inherent quantum randomness to create unique and unpredictable encryption keys enabling virtually impenetrable communications, the press release said. [Read more…]

Federal site cleanup workers reported in August that they had begun removing contaminated sludge and debris from tanks, sumps, and valve boxes at Oak Ridge National Laboratory’s liquid and gaseous waste operations using a powerful, new trailer-mounted vacuum.

The equipment has already enhanced safety and operational efficiency, according to the U.S. Department of Energy Office of Environmental Management.

“Without the vacuum, personnel would be required to fully dress in personal protective equipment and remove the sludge and debris with shovels and buckets,” DOE said. “In addition to being closer to contaminated materials in confined spaces, workers would face an increased chance of slips and falls while climbing in and out of slippery areas in the protective suits.”

Using the vacuum technology has eliminated the risk of heat stress for employees, who would otherwise perform manual labor in protective suits during the hot Tennessee summer, DOE said. [Read more…]
