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…]

The Y-12 National Security Complex in Oak Ridge has been approved to produce a major component of a nuclear bomb known as the B61-12.

The approval was the final step to authorize the manufacturing and delivery of the first production unit of a component called the canned subassembly. It’s scheduled for March 2019, according to Y-12. A canned subassembly is the second stage of a modern thermonuclear weapon, and it is part of the nuclear explosives package.

The Y-12 work is part of the B61-12 Life Extension Program, which will consolidate four versions of the bomb into one. The bombs could be carried on B-2A bomber aircraft and F-15Es, several types of F-16s, and PA-200 fighters, and in the future, F-35s and B-21s.

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…]

Nuclear materials and operations have been removed from an old building at the Y-12 National Security Complex, and that improves safety and reduces the risk to workers and the public, a federal safety board said.

The building, 9204-2, or Beta 2, is on the west side of Y-12. It’s one of nine buildings at the 811-acre site that once used machines known as calutrons to enrich uranium for atomic bombs as part of the top-secret Manhattan Project during World War II. It’s now used to produce lithium for nuclear weapons.

In an early September report, the Defense Nuclear Facilities Safety Board said Consolidated Nuclear Security and the National Nuclear Security Administration Production Office had officially downgraded Building 9204-2. It had been a category two hazard, but it is now less than category three. It’s considered non-nuclear.

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…]
