Photos released by the City of Oak Ridge and CNS Y-12 on Monday show the landslide that occurred next to the access road to the Oak Ridge Water Treatment Plant on Pine Ridge in February.

Last week, Oak Ridge Public Works Director Shira McWaters said it could cost an estimated $407,000 to repair the landslide, and the work should be complete by the end of July.

The water plant is on a ridge top above the main entrance to the Y-12 National Security Complex on Bear Creek Road. The landslide occurred next to the access road to the water plant on Saturday night, February 23. It’s the only access road to the water plant. It allows operations and maintenance workers to get to the water plant and deliver materials, equipment, and chemicals.

Filmmaker Keith McDaniel has completed a nine-year project to document the oral histories of about 400 current and former Oak Ridge residents, including those connected to the Manhattan Project during World War II.

The life stories were used to build a digital collection for the Oak Ridge Public Library’s Center for Oak Ridge Oral History, or COROH. McDaniel was part of the group that made plans for the COROH and, following the city’s receipt of an annual grant from the U.S. Department of Energy, took the contract for the documentary work.

“A lot of original Oak Ridgers were dying and getting older,” McDaniel said in a press release from Carson-Newman University. “We felt it was really important to collect their memories, to collect their stories.”

The one-on-one filmed interviews gave those connected to the Manhattan Project, and later to the city at large, the opportunity to share their life stories, the press release said.

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.
