The U.S. Nuclear Regulatory Commission has approved a construction permit for a test reactor at Heritage Center industrial park in west Oak Ridge. The NRC decision was announced Tuesday, and construction could start next year.

The 35-megawatt thermal Hermes demonstration reactor would be built by Kairos Power, which has headquarters in Alameda, California, and a Tennessee operation in Oak Ridge.

Hermes would use molten salt to cool its reactor core. It would not generate electricity. Instead, it would provide operational data to support the development of a larger version for commercial power, the NRC said.

“A critical step on Kairos Power’s iterative pathway to commercializing its advanced reactor technology, the Hermes reactor will demonstrate the company’s ability to deliver clean, safe, and affordable nuclear heat,” the company said in a press release.

The Tennessee Valley Authority has retired the Bull Run Fossil Plant in Claxton.

The plant burned the last of its onsite coal onsite in August, ending a 48-day run. TVA retired the plant December 1.

The TVA Board of Directors approved the retirement of Bull Run on February 14, 2019. That followed an environmental review process that included public input, TVA said.

Bull Run began operating in 1967. At the time it was the largest in the world in the volume of steam produced, according to TVA. Located on 750 acres in Claxton across from Oak Ridge, it was the only single-unit power plant in the TVA system, and it was designed to produce up to 950 megawatts. It has an 800-foot reinforced concrete chimney.

A standing-room-only crowd attended the grand re-opening celebration of renovations to the East Wing of the Oak Ridge Public Library on Tuesday.

The renovations include a brand-new Children’s Room and bathrooms that meet Americans with Disability Act standards.

The projects were made possible through a combination of funding from the City of Oak Ridge, a Support Grant to Local Governments, and the Friends of Oak Ridge Public Library administering a bequest (a personal property gift) on behalf of Jerry Kinnamon.

The Brentwood company performing preliminary studies for the proposed Oak Ridge Airport could evaluate leaving a short section of railroad in place and building a runway bridge over it.

The short section of railroad has been called a potential “deal-killer” for the airport.

Power to TRISO at Horizon could cost $13 million

By 2 Comments

This map shows the potential route of 69-kilovolt overhead power lines for the TRISO-X nuclear fuel facility at Horizon Center in west Oak Ridge, starting at the substation (SUB) on the south side of Highway 95/58 (lower right), continuing up Novus Drive (center right), crossing onto Horizon Center land, and then running east (to the right) on the back side of Site 6 (open area at upper right).

Building a new substation and electrical lines to supply power to a nuclear fuel company could cost $13 million, Oak Ridge officials said in December.

The nuclear fuel company, TRISO-X, needs about 32 to 35 megawatts of electricity at Horizon Center in west Oak Ridge. That would make the company the city’s biggest electrical customer. (Oak Ridge National Laboratory and Y-12 National Security Complex get most of their power directly from Tennessee Valley Authority.)

The Tennessee Valley Authority on Wednesday said it takes “full responsibility” for the impact of the first-ever mandatory power outages during the cold weather on Friday and Saturday last week, and it is reviewing what happened.

“We at TVA take full responsibility for the impact we had on our customers,” the electrical provider said in a press release posted on its website. “We never want to impact anyone’s energy at any time. This is not the way we want to serve our communities and customers.

“We are conducting a thorough review of what occurred and why. We are committed to sharing these lessons learned and—more importantly—the corrective actions we take in the weeks ahead to ensure we are prepared to manage significant events in the future.”

TVA: Power supply set record Friday

The Tennessee Valley Authority said it delivered a record amount of power on Friday and set a winter record for peak power demand.

TVA supplied 740 gigawatt-hours, or 740 million kilowatt-hours, during a 24-hour period on Friday, December 23. That’s more energy supplied than at any other time in its 89-year history, TVA said.

The cold also produced a winter record for peak power demand of 33,425 megawatts at 7 p.m. Central time, when the region-wide average temperature was 9 degrees, TVA said.

“Record-setting temperatures across the region continue to put intense pressure on the power system,” TVA said in a press release. “The Tennessee Valley Authority and local power companies (worked) around the clock in difficult conditions to meet this extreme demand.”

The U.S. Nuclear Regulatory Commission announced Friday that it will prepare an environmental impact statement for a proposed nuclear fuel fabrication facility in Oak Ridge that could help power advanced reactors for electrical and chemical use, the U.S. Department of Defense, and the National Aeronautics and Space Administration (NASA).

The project could partially benefit from last year’s federal infrastructure law, specifically about $1.1 billion appropriated for a clean energy supply.

Nuclear fuel company TRISO-X needs electrical power for a manufacturing facility in Horizon Center by December 2024, and the Oak Ridge Electric Department wants the authority to spend up to $3 million to help make that possible.

If approved by Oak Ridge City Council, the money would be used to design and build a new electric substation and distribution network to provide power to Lot 6 on the back side of Horizon Center, which is on the west side of town. The work would include engineering design, land surveys, site clearing, the purchase of materials, and acquiring permits and other required items.
