Two new bus tours offered in Oak Ridge in August will allow you to learn more about the unique heritage of the Manhattan Project, a press release said. The bus tours are the “Secret City” and “Oak Ridge Museums” tours.

The “Secret City” tour will be led by a National Park Service ranger, last three hours, and include that day’s admission to the American Museum of Science and Energy.

“During the Manhattan Project, a community was created almost overnight to accomplish the monumental task of producing enriched uranium on a large scale,” the press release said. “During the tour, visitors can develop an understanding of what life was like during World War II in a city behind a fence that no one was supposed to discuss. The tour will also include a visit to the X-10 Graphite Reactor, a National Historic Landmark, and the world’s first nuclear reactor designed and built for continuous operation.”

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.

Titan, once the world’s fastest computer, will be retired Aug. 1

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.

Note: This story was updated at 8:30 p.m.

The Oak Ridge City Council voted 5-0 Monday evening to approve an initial debt resolution worth up to $45 million for the construction of a new water treatment plant and related infrastructure.

The five members voting in favor of the resolution were Oak Ridge Mayor Warren Gooch, Mayor Pro Tem Rick Chinn, and Council members Jim Dodson, Chuck Hope, and Ellen Smith. Council members Kelly Callison and Derrick Hammond were absent.

The water plant would be built near the city’s water intake on the Clinch River in south Oak Ridge. The cost of the new plant, which could produce about 16 million gallons of water per day, is currently estimated at about $42.9 million.

City officials have been discussing the new water plant for several years and have had an engineering firm study the project.

The city is repairing a large landslide that occurred next to the access road to the Oak Ridge water treatment plant on Pine Ridge above the Y-12 National Security Complex during the rainy month of February.

The landslide occurred on the night of February 23, Oak Ridge Public Works Director Shira McWaters told City Manager Mark Watson in a June 24 memo. The access road is the only access road to the city’s water plant, and it’s critical to being able to operate the water plant, McWaters said. The road allows operations and maintenance workers to get to the water plant and deliver materials, equipment, and chemicals.

Repairs were started immediately after the landslide to minimize the risk of more damage to the area and the potential to lose the only access road to the plant, McWaters said. She said work started in March and should be complete by the end of July.

The water plant provides water to both the City of Oak Ridge and to U.S. Department of Energy sites, including Y-12 and Oak Ridge National Laboratory. The plant is on a ridge at the southern entrance to central Oak Ridge above the main entrance to Y-12 at Bear Creek Road and Scarboro Road.

Earl Davis

By Bob Fowler, Roane State staff writer

Shortly after his 40th birthday, Morgan County resident Earl Davis had an epiphany.

“Looking ahead 20 years, I didn’t see myself with a pitchfork in my hands doing heavy labor,” the Lancing resident said. In the past, he worked at a chicken farm and as a prison guard.

So Davis, who graduated from Wartburg Central High School in 1994, started saving his money to pay for college tuition.

“Then I found out about the Reconnect program,” he said. That’s the state’s grant program where adults can attend a community college tuition-free. [Read more…]

No injuries were reported when lightning sparked a fire in a bedroom in Oak Ridge on Tuesday, firefighters said.

The Oak Ridge Fire Department responded to reports of a tree being struck by lightning in the 100 block of Baltimore Drive at about 4:15 p.m. Tuesday, July 2.

Firefighters said the energy from the lightning strike ran into a nearby home, causing the electrical outlets in a bedroom to arc. The electrical arcing set a bed on fire, which heavily damaged the bedroom and its contents, a press release said.

The U.S. Nuclear Regulatory Commission has scheduled a hearing for an application for a site in west Oak Ridge where small modular nuclear reactors could be built.

The hearing has been scheduled for 9 a.m. Wednesday, August 14, at the NRC in Rockville, Maryland.

The NRC will discuss an early site permit application submitted by the Tennessee Valley Authority for the Clinch River Nuclear Site. TVA has proposed using the 935-acre site, which is along the Clinch River south of Heritage Center (the former K-25 site), to build two or more small modular reactors. The site once hosted the former Clinch River Breeder Reactor Project.

During the August 14 hearing, the NRC will have an evidentiary session to hear testimony and receive exhibits in the uncontested proceeding for TVA’s early site permit application, according to a notice published in the Federal Register on Monday.

The Federal Aviation Administration provided a conditional approval for the proposed Oak Ridge Airport in a February letter, a consultant said Thursday.

The conditions included in the February 22 letter included the completion of a benefit cost analysis and an environmental assessment for the airport property, project consultant Billy Stair said.

In response to the conditional approval, the Metropolitan Knoxville Airport Authority’s board of directors approved a work authorization for CHA Consulting Inc. during a June 19 meeting. CHA Consulting, which has an office in Louisville, will provide professional services for “qualifications development and agency scoping” for the design, environmental assessment, and benefit cost analysis for the proposed airport.

“This puts in motion the process for undertaking the BCA (benefit cost analysis) and EA (environmental assessment),” Stair said.
