It’s been a dream for years, and now the preservation and transformation of the former Alexander Inn is nearly complete.

The two-year, $8 million construction and renovation project is almost finished, and Alexander Guest House could open as an assisted living facility in about two weeks, said Rick Dover of Dover Development of East Tennessee.

Sixty percent of the 64 apartments are already reserved, Executive Director Jody Daugherty said during a media tour Wednesday. Among those who will live there are Jean Stone of Oak Ridge and Dean Ford of Oliver Springs. They participated in the media tour on Wednesday.

“I think they’ve done a remarkable job of restoring it to its grandeur,” said Stone, a longtime Oak Ridge resident who has “many fine memories” of parties, weddings, wedding receptions, and club meetings, among other events, at the historic two-story hotel. “Once I saw what they’re doing here, I wanted to come here. I think it will be a lovely place to live. It’s absolutely tremendous.”

The historic two-story hotel was built as part of the top-secret Manhattan Project during World War II, and top scientists and dignitaries once stayed there. [Read more…]

A car and house built using large-scale 3D printers at Oak Ridge National Laboratory can provide power to each other, and they’re part of a project designed to answer “what if” questions that could lead to innovations in building and car construction and energy use, storage, and consumption, researchers and officials said Wednesday.

The 210-square-foot house—it’s a solar-powered building—and the printed utility vehicle—officials affectionately call it a PUV—were printed at ORNL’s Manufacturing Demonstration Facility on Hardin Valley Road.

They were unveiled at ORNL on Wednesday during the lab’s first-ever Industry Day. The building and PUV are part of a project called the Additive Manufacturing Integrated Energy, or AMIE, demonstration.

Additive manufacturing is the process used to build something one layer at a time. One of the most well-known examples is the Shelby Cobra car 3-D printed on a large-scale polymer printer at the MDF. President Barack Obama and Vice President Joe Biden admired that vehicle—and joked about taking it for a spin—during a trip to East Tennessee in January. [Read more…]

The City Council will get an update on the proposed general aviation airport in west Oak Ridge during a work session this evening.

The update will be given by Billy Stair, public affairs consultant for the Metropolitan Knoxville Airport Authority.

The airport could cost $30-$40 million, and construction could start in 2018, according to a current timeline and construction estimate. The airport would include a 5,000-foot runway and be built at the front side of Heritage Center, the former K-25 site.

The Oak Ridge airport would the third for the MKAA, which would own the site. The other two are McGhee Tyson in Blount County and Downtown Island in Knoxville. The Oak Ridge airport would be a reliever airport and help relieve congestion at the other two airports. [Read more…]

New ORNL catalyst addresses engine efficiency, emissions quandary

A catalyst being developed by researchers at the U.S. Department of Energy’s Oak Ridge National Laboratory could overcome one of the key obstacles still preventing automobile engines from running more cleanly and efficiently.

The mixed oxide catalyst could solve the longstanding problem of inhibition, in which nitrogen oxides, carbon monoxide, and hydrocarbons effectively clog the catalyst designed to cleanse a vehicle’s exhaust stream. This happens as these three pollutants compete for active surface sites on the catalyst. Now, however, ORNL’s low-cost catalyst composed of copper oxide, cobalt oxide, and cerium oxide shows considerable promise when tested in simulated exhaust streams.

“Our catalyst potentially fixes the inhibition problem without precious metals and could help more efficient engines meet upcoming stricter emission regulations,” said Todd Toops of ORNL’s Energy and Transportation Sciences Division. Toops noted that the unique formulation builds on previous work by colleagues Andrew Binder and Sheng Dai, who varied the composition of the three catalyst components in search of improved oxidation activity under simple conditions.

Y-12 Process Buildings and Mercury Use Area

Note: This story was last updated at 3:30 p.m.

Construction on a mercury treatment plant at the Y-12 National Security Complex could start in 2018 and cost $146 million, a federal official said Wednesday.

The plant would treat mercury contamination that originates in the West End Mercury Area at Y-12, flows through storm drains, and enters Upper East Fork Poplar Creek at a point known as Outfall 200. East Fork Poplar Creek flows through Oak Ridge.

The U.S. Department of Energy has evaluated several alternatives for treating the mercury, including doing nothing. But DOE prefers an option that would treat 3,000 gallons of contaminated water per minute and store two million gallons of stormwater. It could reduce the flow of mercury, a toxic metal, by an estimated 84 percent. [Read more…]
