The Oak Ridge City Council on Monday will consider hiring an engineering company to evaluate the city’s 70-year-old water plant. There are questions about whether Oak Ridge and the U.S. Department of Energy should continue to invest money in the water plant, build a new one at a new site, or consider other alternatives.

The Council on Monday will consider awarding a $98,250 contract to Jacobs Engineering Group Inc. of Knoxville to evaluate the plant. Jacobs Engineering has offices in Oak Ridge.

The city’s 1940s-era water treatment plant is on Pine Ridge above the Y-12 National Security Complex, and it provides water to businesses and residents of Oak Ridge, as well as to DOE.

“The plant is currently 70-plus years old and continues to show signs of aging despite efforts over the last 15 years to modernize and upgrade,” said Shira McWaters, the new Oak Ridge Public Works director. “Many of the plant’s assets are near or have exceeded their useful life cycle and require replacement or major rehabilitation.”

Discussions about the future of the current plant came up as the city and DOE negotiated a contract extension for water supplied to Y-12 and Oak Ridge National Laboratory. [Read more…]

The Tech 2020 Board of Directors approved a plan Tuesday that allows many of the organization’s top initiatives to be continued under the leadership of other enterprises, officials said. The Tech 2020 building, which is located in Commerce Park in south Oak Ridge, will be sold.

In January, the Tech 2020 Board agreed to wind down operations after more than two decades.

“Our goal these past few months has been to preserve some of Tech 2020’s important resources, and we believe we’ve accomplished that with the plan approved at Tuesday’s meeting of the Board,” said David Bradshaw, Tech 2020 chair.

That plan calls for the transfer of several of the Tech 2020 regional missions to other organizations on or before April 30, and the financial assets of a fourth to be returned to its founding members, a press release said.

“When the Board voted on January 26 to wind down operations, it asked that we explore options to transition existing missions to other not-for-profit organizations,” Bradshaw said in the press release. “We asked interested organizations to outline their ideas, and we are pleased that several have stepped forward with concrete proposals.” [Read more…]

City approves water contract extension for Y-12, ORNL, but DOE rates questioned

The Oak Ridge City Council on Tuesday approved a one-year, $2.1 million contract extension for water supplied to Oak Ridge National Laboratory and Y-12 National Security Complex, but a few members questioned whether the U.S. Department of Energy is paying a fair rate.

The one-year extension is expected to give the city time to have a qualified third-party engineering firm study the city’s aging water plant on Pine Ridge above Y-12, consider what is needed, and develop options that could help Oak Ridge decide whether to renovate the 70-year-old facility—or build a new one at a new site.

City officials said bringing the existing plant up to code could cost $16 million or more. It was transferred to the city from DOE in 2000, more than 15 years ago. Officials declined to estimate how much it could cost to build a new one, although it’s also said to be in the multi-million-dollar range.

Among the challenges at the water plant now are a leak of 3,000 gallons per day. The city staff is not sure where the leak originates or whether the water that is leaking has already been treated, and so far they haven’t been able to stop the leak. [Read more…]

The small nuclear reactors that could be built along the Clinch River could provide enough electricity to power several cities the size of Oak Ridge. They could also be, depending upon the timing, the first commercial reactors of their type in the United States.

They’re known as small modular reactors, or SMRs. They could generate 80 to 200 megawatts each. One hundred megawatts is enough to power about 60,000 homes. Oak Ridge has about 12,000 homes.

Several companies are working on SMR designs, but so far none have been certified by the U.S. Nuclear Regulatory Commission, said Jim Hopson, public relations manager for the Tennessee Valley Authority.

By May 12, TVA plans to submit an application to the NRC for what is known as an early site permit to build SMRs on the Clinch River Site in west Oak Ridge. Hopson likened an early site permit, or ESP, to a pre-approval for a home loan, although he said that is an oversimplification.

“It’s similar to pre-approving yourself for a loan,” Hopson said Friday. “You get the preliminaries out of the way.” [Read more…]

What if charging your plug-in electric vehicle was as easy as parking it? No need for cords or cards. Just as Wi-Fi has freed consumers of wires when accessing the Internet, wireless charging technology may soon be as widespread, thanks to research supported by the U.S. Department of Energy.

With support from the Vehicle Technologies Office, Oak Ridge National Laboratory and Hyundai America Technical Center Inc. have been working since 2012 to demonstrate wireless charging on a variety of vehicles. ORNL is working with a mix of Toyota vehicles, including models of the all-electric RAV 4, plug-in hybrid electric Prius, and all-electric Scion iQ, while Hyundai America Technical Center Inc. is testing its technology on five all-electric Kia Souls.

The technology behind wireless charging creates a connection between a transmitting pad on the ground (such as in a garage) and a receiving pad integrated on the bottom of the vehicle. In the projects ORNL is leading, the transmitting pad is connected to a 240-volt outlet and generates a magnetic field of a certain frequency. When the coil in the receiving pad is tuned to oscillate at the same frequency, the magnetic field will generate a current in the receiving coil, charging the vehicle’s battery. [Read more…]
