Researchers at Oak Ridge National Laboratory have demonstrated a 120-kilowatt wireless charging system for vehicles—providing six times the power of previous ORNL technology and a big step toward charging times that rival the speed and convenience of a gas station fill-up.

The wireless system transfers 120 kilowatts of power with 97 percent efficiency, which is comparable to conventional, wired high-power fast chargers. In the laboratory demonstration, power was transferred across a six-inch air gap between two magnetic coils and charged a battery pack.

ORNL researchers created and demonstrated the world’s first 20-kilowatt wireless charging system, which is being modified for applications such as commercial delivery trucks.

“It was important to maintain the same or smaller footprint as the previous demonstration to encourage commercial adoption,” said project lead Veda Galigekere of ORNL’s Power Electronics and Electric Machinery Group. [Read more…]

The Y-12 National Security Complex in Oak Ridge has been approved to produce a major component of a nuclear bomb known as the B61-12.

The approval was the final step to authorize the manufacturing and delivery of the first production unit of a component called the canned subassembly. It’s scheduled for March 2019, according to Y-12. A canned subassembly is the second stage of a modern thermonuclear weapon, and it is part of the nuclear explosives package.

The Y-12 work is part of the B61-12 Life Extension Program, which will consolidate four versions of the bomb into one. The bombs could be carried on B-2A bomber aircraft and F-15Es, several types of F-16s, and PA-200 fighters, and in the future, F-35s and B-21s.

Oak Ridge trailed Powell in the first half on Blankenship Field on Friday but took the lead and a 28-21 win in the second half.

It was the second week in a row that Oak Ridge (8-1, 5-0 Region 3-5A) struggled in the first half but played better in the second. Last week, Oak Ridge led Clinton 24-21 at halftime but then scored 30 points in the second half to beat the Dragons 54-28.

The Wildcats will meet the only other undefeated team in the region, Fulton (also 8-1, 5-0), at 7 p.m. Thursday in Oak Ridge for the region championship. It’s the last regular-season game.

Powell (1-8, 1-5 after forfeiting six wins due to an ineligible player) had a 21-7 lead over Oak Ridge halfway through the second quarter on Friday. But the Wildcats narrowed the lead to 21-14 on a two-yard run by senior Jordan Graham with 1:20 remaining before halftime. The Wildcats then scored two more touchdowns in the second half while holding the Panthers scoreless.

Clinton Mayor Scott Burton announced in a special report on Thursday that a Knoxville developer has entered into an agreement to purchase the former Magnet Knitting Mills site in downtown Clinton.

The property is along Charles G. Seivers Boulevard. It has been a contentious topic of conversation and debate in the Clinton area for several years, according to a press release from Burton, the mayor. He described the Knoxville developer as community-conscious.

“While the current owner has obtained a permit for the demolition of the existing two-story brick building, the potential new owner has another multi-use vision for the site,” the press release said. “Upon completion of the sale and the transfer of the property to the new owner, the City of Clinton will work with the Knoxville owner/developer to rehabilitate the site for future live-work, retail, and commercial use. This rehabilitation would include the renovation of the existing building and preservation of Clinton’s downtown.” [Read more…]

The Oak Ridge City Council has approved two construction contracts worth $11.1 million total for two projects that have been discussed for years: a new Oak Ridge Preschool and new Oak Ridge Senior Center. The Preschool contract includes improvements at Scarboro Park, where the Preschool will be built.

Both contracts were awarded to Jenkins and Stiles LLC of Knoxville. Council approved them in two 7-0 votes during a special meeting on Thursday afternoon.

Both projects will be funded through general obligation bonds, a type of debt. The bonds could go to market in November and close in December.

The first contract awarded Thursday is for the construction of the Preschool and improvements to Scarboro Park. It is worth up to about $8.4 million. The Preschool is expected to be complete by November 30, 2019.  [Read more…]

The Oak Ridge City Council in a special meeting on Thursday will consider $11.1 million in construction contracts for the new Oak Ridge Preschool, Oak Ridge Senior Center, and Scarboro Park improvements.

The contracts could both be awarded to Jenkins and Stiles LLC of Knoxville.

There were four bidders for the Senior Center project and three for the Preschool and Scarboro Park improvements, according to Jacene Phillips, senior project manager for Studio Four Design. Her company recommended both contracts be awarded to Jenkins and Stiles because of cost, but also because the Senior Center could be operating two months earlier under that contract than under any other bid and the Preschool would be complete three days before it would be under the other bids, Phillips said.

Both projects would be funded through general obligation bonds, a type of debt that could be issued in November.

The first contract that could be awarded Thursday is for the construction of the Preschool and improvements to Scarboro Park. The contract would be worth up to about $8.4 million. The Preschool would be built at Scarboro Park. [Read more…]

There is a public availability session on the proposed federal landfill in Oak Ridge on Thursday.

The U.S. Department of Energy has issued a proposed plan to build a new landfill on the Oak Ridge Reservation. The landfill, the Environmental Management Disposal Facility, would be in Bear Creek Valley west of the Y-12 National Security Complex. It is intended for disposal of radioactive, hazardous, and toxic wastes. It would be used as cleanup work ends at the East Tennessee Technology Park and the existing landfill, the Environmental Management Waste Management Facility fills up, and cleanup work moves to Y-12 and Oak Ridge National Laboratory.

A press release said the Sierra Club has invited state and federal officials from DOE, Environmental Protection Agency, and Tennessee Department of Environment and Conservation to be available for public questions about the Environmental Management Disposal Facility. The public availability session has been scheduled from 2 to 8 p.m. Thursday, October 11, at the TDEC office at 761 Emory Valley Road in Oak Ridge. [Read more…]
