A Japanese supercomputer has displaced the Summit supercomputer at Oak Ridge National Laboratory as the world’s most powerful and bumped other U.S. and Chinese machines down one spot on a semiannual list of the fastest systems.

Summit had been ranked the world’s most powerful supercomputer on the semiannual TOP500 list since June 2018. It was bumped to number two when the new TOP500 list was released Monday.

The new top system is installed in Kobe, Japan, and it is named Fugaku. In a high-performance test, it performed at 415.5 petaflops. A petaflop is a quadrillion floating-point operations per second.

Fugaku’s performance was 2.8 times better than Summit’s, according to TOP500. Summit delivered 148.8 petaflops on the high-performance test.

The UCOR contract to clean up federal sites in Oak Ridge has been extended one year to July 31, 2021, and the consideration of a new cleanup contract won’t be considered until November 2020 at the earliest.

The UCOR contract could be extended one additional year, to July 31, 2022, using two six-month options, depending upon contractor performance and progress.

Before the extension, UCOR’s contract had been scheduled to expire July 31, 2020.

UCOR works on cleanup projects for the U.S. Department of Energy at the East Tennessee Technology Park, Oak Ridge National Laboratory, and Y-12 National Security Complex. The work includes the demolition of old, contaminated buildings that are no longer used. The cleanup work is called environmental management, or EM.

Construction work has started on a part of a project to double the power of the proton beam in the Spallation Neutron Source at Oak Ridge National Laboratory.

It’s the first construction work at the $1.4 billion SNS since 2006.

The current work is limited to what is known as the klystron gallery. It houses radio-frequency systems. They power the structures that are used to accelerate a negatively-charged hydrogen ion beam in the linear accelerator at SNS.

ORNL has previously said the klystron gallery construction could last about one year.

The work is part of a project called the proton power upgrade, or PPU. It will eventually double the power of the SNS proton beam from 1.4 megawatts to 2.8 megawatts. That could be a seven-year project. The potential cost has previously been estimated at $245 million.

Engineers at Oak Ridge National Laboratory are making metal molds that companies will use to manufacture plastic tubes for COVID-19 test kits.

The work has been cited in two federal coronavirus task force press conferences at the White House this week.

On Monday, Brad Smith, a federal health official, said the ORNL work could help supply more than 40 million collection tubes per month in the next several weeks. Smith grew up in Knoxville, and he has been a business leader and entrepreneur, and served in Tennessee state government. He is now deputy administrator and director of the U.S. Centers for Medicare and Medicaid Services.

The ORNL work was also cited by President Donald Trump on Sunday.

The ORNL engineers are using additive manufacturing to produce the metal molds for the COVID-19 test kits. Additive manufacturing is the process of making an object by printing it with a material layer by layer. Printers known as 3D printers— some large, some small—can be used.

A researcher at Oak Ridge National Laboratory helped discover a small cave snail.

The new snail species has been named the Tennessee cavesnail, or Antrorbis tennesseensis. Its name honors the state where it was found and the fact that several researchers involved in its discovery are affiliated with the University of Tennessee. A paper describing and naming the species was published in December.

The snail, which is less than two millimeters long, was found in two caves in Roane County a few miles south of the Oak Ridge Reservation. The reservation includes ORNL and parts of the city of Oak Ridge.

The snail is found on or under rocks far inside the caves, usually in streams that aren’t too muddy or silty, ORNL said. Researchers recommended that the species be listed as endangered.

The ORNL researcher is Evin Carter. He is a research associate and wildlife ecologist at ORNL, which is a U.S. Department of Energy laboratory. With only a handful of surveys completed so far, Carter has plans to survey the 40 or so other caves on the Oak Ridge Reservation, ORNL said.

More than 60 percent of the 5,200 staff members at Oak Ridge National Laboratory are working remotely.

No staff members have tested positive for COVID-19, a contagious respiratory disease that has spread around the world and can be deadly. But ORNL does have employees that have been put in self-quarantine by the lab’s medical director. That includes staff members who believe they, or a member of their household, may have come in contact with a person who has tested positive for COVID-19 or a person who has recently traveled to an area where widespread community spread of COVID-19 has been confirmed.

The remote work at ORNL is being done by staff members in a wide variety of jobs that include support functions like accounting, auditing, legal, technical editing, project management, and other activities, as well as researchers who can monitor data remotely or who are using the time to write or edit research publications and similar work, ORNL said in a response to questions on Wednesday.

Between 1,500 and 2,000 staff members continue to work on site, largely in facility operations positions that require hands-on tasks or monitoring, the lab said. These include technicians, front-line supervisors, electricians, firefighters, security personnel, and other types of workers.

“Some tasks have been shuffled to accommodate the need to work from home, but we are continuing to fulfill our mission commitments to the U.S. Department of Energy and the nation,” ORNL said.

Oak Ridge National Laboratory is directing staff members who can to work from home, and for now, the lab is not allowing travelers from foreign countries, regardless of nationality.

ORNL cafeterias will be open for carryout only.

In response to questions Tuesday, ORNL said it has not been notified that any staff member is presumed or confirmed to be COVID-19 positive. COVID-19 is the respiratory illness caused by the new coronavirus. The lab said it is taking proactive measures to reduce the severity of the COVID-19 outbreak and to best protect themselves, their families, and their communities.

“Stopping the spread of the virus will prevent hospitals and other medical facilities from becoming overwhelmed by a spike in patients sickened by COVID-19,” ORNL said. “This is quite literally a life or death matter, and early action is key.”

DOE plans to demolish world’s oldest operating nuclear facility

The U.S. Department of Energy plans to demolish the oldest operating nuclear facility in the world.

The cleanup and demolition of Building 3019 at Oak Ridge National Laboratory could start sometime around 2030.

But the work won’t start until more than 500 canisters of uranium-233 stored in the building have been processed and removed, possibly by 2025.

More than 70 years old, Building 3019 was built during World War II as part of the top-secret Manhattan Project. That was a top-secret federal program to build the world’s first atomic bombs.

From 1943-1976, the building was used as a pilot plant to test radiochemical processes before they were used on a large scale at other nuclear facilities.

Now Building 3019 stores the nation’s inventory of uranium-233. Processing and removing that uranium is the top cleanup priority at ORNL because, among other things, storing the highly enriched fissile nuclear material increases security costs and creates nuclear safety issues. The cleanup work is being done by DOE’s Oak Ridge Office of Environmental Management and its contractor Isotek.

With key isotopes depleted, DOE plans production center at ORNL

Posted at
By Leave a Comment

The U.S. Department of Energy has proposed an isotope production and research center at Oak Ridge National Laboratory that could be important for medical, national security, and research projects.

In a budget request released in February, DOE said its supply of certain key enriched stable isotopes has been depleted, making the United States more dependent upon foreign imports for enriched stable isotopes. Isotopes are forms of an element that have the same number of protons but different number of neutrons in their nuclei.

DOE said the demand for enriched stable isotopes continues to grow substantially, including for the medical, national security, and fundamental research projects.

The new center at ORNL, the U.S. Stable Isotope Production and Research Center, would reduce the nation’s dependence upon foreign countries for those isotopes, DOE said.

DOE approved the mission need for the facility in January 2019. Although the cost range could change, the current project estimate is between $175 million and $298 million.
