Construction is planned in December for a project to upgrade proton power at the Spallation Neutron Source at Oak Ridge National Laboratory.

The construction could last about one year, and it will be limited to the buildout of what is known as the klystron gallery, ORNL said in June. The klystron gallery houses the radio-frequency systems that power the structures used to accelerate a negatively-charged hydrogen ion beam in the linear accelerator at SNS.

SNS generates neutrons for scientific research by propelling protons down a linear accelerator. When the protons collide with a liquid mercury target, they create a “spall” of neutrons that are sent down beam lines surrounded by research instruments.

The proton power upgrade will eventually double the power of the SNS proton beam from 1.4 megawatts to 2.8 megawatts. The current total estimated project cost is $245 million.

Note: This story was updated at 12 p.m. July 19.

Four workers received small external radiation doses and a planned outage of the Spallation Neutron Source was started a few days early after an unexpected “pressure transient” in March, according to Oak Ridge National Laboratory.

The low radiation dose levels (less than 25 millirem) were well below the regulatory threshold of 5,000 mrem annual exposure, which was established to protect worker safety, ORNL said in June.

The pressure transient occurred in the SNS mercury loop. When radiation was detected, ORNL staff closed off the affected area and reviewed workers’ dosimeters.

“Readings showed four workers received small external doses, none more than 25 millirem,” ORNL said.

For comparison, a chest x-ray produces a radiation dose of about 6 mrem; a mammogram about 13 mrem, and a head and chest CT scan is 1,100 mrem[1].

An Oak Ridge Institute approved in June is expected to foster a stronger, more coordinated relationship between the University of Tennessee and Oak Ridge National Laboratory.

In June, the University of Tennessee System Board of Trustees approved a resolution creating the Institute, which will be at the University of Tennessee. It will move five joint UT and ORNL programs under a single administrative “umbrella,” the university reported.

It will allow the coordinated expansion of graduate education programs to prepare scientists and engineers for a global economy that demands interdisciplinary problem-solving, teamwork, and innovation, according to a resolution proposing the Institute.

“Coordination of joint efforts through ORI (Oak Ridge Institute) will promote greater focus, efficiency, and accountability; ensure innovative education, training, and workforce development; and provide flexibility to respond to emerging research challenges and the potential of disruptive technologies,” the resolution said.

The Oak Ridge Institute will build on the “track record of success” established by ORNL and UT, the resolution said. It will be led by an executive director who will pursue interdisciplinary research and workforce development in emerging fields.

When people think of glass blowing, they think of unique vases and colorful works of art made in places like Dollywood or Asheville. Not many people know that Oak Ridge has its very own scientific glass blowers working for the Oak Ridge National Laboratory.

ORNL has its own glass shop on site. Scientific Glassblower and Shop Manager Jason Craig has been blowing glass for almost 25 years.

According to Craig, ORNL has always had a glass shop. The glass shop now has been in its current building since 1955. There used to be 10 glass blowers at ORNL, and two or three at the Y-12 National Security Complex. Now Craig and Carlos Rodriguez-Flores are the two full-time glassblowers, with a retired glass blower who comes in part-time.

Here are photos from the glass shop by Kate Trabalka, a media and communications student who is concentrating on journalism at East Tennessee State University and helping Oak Ridge Today with stories and photos this summer. See Trabalka’s story here. See her videos here.

Craig started out as an artistic glass blower before transitioning to scientific glass blowing.

“Working in a (glass shop) at a research facility is much different than blowing glass in a production shop or for artistic glass blowing,” Craig said during an interview in the ORNL glass shop last week. “So, I guess my greatest challenge is just trying to…keep track of the customers and the jobs and ordering materials, inventory, and gas cylinders, and all that stuff…We’re basically running our own business here inside the laboratory.”

The Titan supercomputer at Oak Ridge National Laboratory debuted as the fastest computer in the world in 2012, and it remained in the top 10 for seven years, providing billions of core hours of total computing time to researchers from around the world. The system will be decommissioned on Aug. 1, 2019, and its data center space will be retrofitted for a new supercomputer, Frontier. (Photo by ORNL)

A supercomputer that was once the world’s fastest will be retired at Oak Ridge National Laboratory on August 1.

The supercomputer is a Cray XK7 machine called Titan. It is operated by the Oak Ridge Leadership Computing Facility. It’s a petaflop system capable of performing up to 27 quadrillion calculations per second.

Titan was the world’s fastest supercomputer in November 2012, but it was bumped to number two by Tianhe-2, a Chinese supercomputer in June 2013. Still, Titan continued to rank as one of the world’s top 10 fastest supercomputers from its debut at number one in 2012 until this June, when it dropped to number 12.

In June, ORNL said Titan, which has been operating for seven years, will be decommissioned on August 1 and disassembled for recycling. Titan will be removed to make room for a new, much more powerful supercomputer, Frontier. That will be an exascale system capable of 1.5 exaflops, or 1.5 quintillion calculations per second (a billion billion calculations per second). Frontier will be a $600 million Cray computer that is expected to be the world’s most powerful when it debuts in 2021.

The Summit supercomputer at Oak Ridge National Laboratory remains the world’s most powerful, according to a ranking list released Monday.

It’s the third time that Summit, a IBM-built supercomputer, has been number one on the semiannual TOP500 list of of the world’s most powerful supercomputers. Summit debuted at number one in June 2018. That was the first time since 2012 that the United States had the most powerful supercomputer in the world. Summit retained the top spot in November.

The Sierra supercomputer at Lawrence Livermore National Laboratory in Livermore, California, remained at number two on the list released Monday, after climbing there from number three in November. The United States continues to have the top two systems in the world, a position that China held a year and a half ago.

Officials celebrated the launch of Summit in a ceremony attended by U.S. Energy Secretary Rick Perry on June 8, 2018. The supercomputer is capable of 200 petaflops, or 200,000 trillion calculations per second. That makes it about eight times more powerful than Titan, its predecessor, which was once the world’s fastest.

Summit delivered a record 148.6 petaflops on a benchmark test called High Performance Linpack, or HPL, a TOP500 press release said Monday. That was a slight improvement from six months ago, when Summit scored 143.5 petaflops. Summit debuted at 122.3 petaflops in June 2018.
