The Tennessee Valley Authority and Kairos Power plan to collaborate on setting up a low-power demonstration reactor at the East Tennessee Technology Park, the former K-25 site in west Oak Ridge.

As part of this agreement, TVA said in a press release Thursday that itwill provide engineering, operations, and licensing support to help Kairos Power deploy the reactor, named Hermes.

“Teamwork is the hallmark of the nuclear industry and, through this partnership with Kairos Power, we can share TVA’s safety and innovation insights to advance nuclear technology while gaining experience with licensing for advanced reactors,” said TVA President and Chief Executive Officer Jeff Lyash. “Nuclear power is the key to fueling our economy with reliable, affordable, and clean electricity, and it is critical to our national security.”

The Tennessee Valley Authority is conducting routine maintenance inside the boiler at the Bull Run Fossil Plant in Claxton, and the activities, which make use of the plant’s public address system, might continue for the next week or so, a spokesman said Monday.

During the maintenance, TVA is using small blasting caps to remove the buildup of slag, a byproduct at the coal-fired plant.

Residents in Anderson County have been asking about the recent sounds of sirens at Bull Run, including at night.

In a statement, TVA spokesperson Scott Brooks said TVA is using the plant’s public address system to alert and communicate with employees on site, but no sirens or other alarms are activated.

The Tennessee Valley Authority could use the potential nuclear reactor site in west Oak Ridge to test new reactors and nuclear technologies.

Oak Ridge Today has previously reported that small modular nuclear reactors could be built at the Clinch River site, although no specific design has been approved or selected. There are additional actions that would have to be completed before any reactors would be built in Oak Ridge, including selection of a design, approval by the TVA board of directors, and issuance of a construction or operating permit by the U.S. Nuclear Regulatory Commission.

The Tennessee Valley Authority is asking for public comment about a proposal to build one or more small or advanced nuclear reactors in west Oak Ridge.

The reactors would be on the Clinch River Nuclear Site, near the Clinch River and south of Heritage Center (the former K-25 site) in Roane County.

The reactors could be advanced or small modular nuclear reactors. They would have a maximum total electrical output of 800 megawatts. They would be smaller than traditional nuclear power plants, and they would produce less power.

Oak Ridge Today has previously reported that the reactors could provide enough electricity to power several cities the size of Oak Ridge

The rebuilding of a large high-voltage transmission tower in Oak Ridge was completed Sunday, and South Illinois Avenue re-opened to traffic at about midnight.

The 155-foot steel lattice tower that had to be replaced was knocked over when a pickup truck crashed into it at about 4:15 p.m. Friday. The tower, which is at Union Valley Road, carries high-voltage Tennessee Valley Authority transmission lines and city transmission and distribution lines.

The four-lane road, the main connection between Oak Ridge and Knox County, was closed for about two days after the crash while crews removed and replaced the damaged transmission tower.

TVA said the crash also caused damage to three smaller structures, and they were repaired.

South Illinois Avenue is expected to re-open by midnight near the University of Tennessee Arboretum after being closed for more than two days because a large high-voltage transmission tower was knocked over near the road in a crash on Friday. The road re-opening is expected to occur before the Monday morning commute.

Power is still out for a small southeast portion of the city near the crash site, including the University of Tennessee Arboretum, the City of Oak Ridge said Sunday evening.

The single-vehicle crash into the Tennessee Valley Authority steel lattice transmission tower was reported at Union Valley Road at about 4:15 p.m. Friday. That section of the four-lane road, also known as State Route 62 and Pellissippi Parkway, has been closed since shortly after the crash. The road is the main connection between Oak Ridge, Knox County, and Knoxville.

TVA and the Oak Ridge Electric Department worked over the weekend to replace the damaged transmission tower, which carries TVA and Oak Ridge power lines. The repair crews had help from the Oak Ridge Police Department and Oak Ridge Public Works Department. It was a complex emergency repair, the City of Oak Ridge said.

The City of Oak Ridge has published photos of the work to replace the high-voltage steel lattice transmission tower knocked over in a single-vehicle crash at Union Valley Road and South Illinois Avenue on Friday.

The city said the Tennessee Valley Authority and Oak Ridge Electric Department crews are working together, with help from the Oak Ridge Police Department and Public Works Department, to “maintain a safe work environment for a very complex emergency repair.

“Crews are working to have South Illinois Avenue at Union Valley Road open as soon as possible,” the city said.

On Sunday, TVA said the repair work could be complete in time to re-open South Illinois Avenue, a four-lane roadway that connects Oak Ridge to Knox County, for the Monday morning commute. That’s assuming there are no delays due to weather or drilling problems.

Work to repair the damage to a Tennessee Valley Authority transmission tower knocked over in a crash on Friday could be complete in time to open South Illinois Avenue (State Route 62) in time for the Monday morning commute, a spokesperson said Sunday.

However, the schedule could be affected by weather and any potential drilling delays.

TVA spokesperson Scott Brooks said heavy equipment, materials, and workers, as well as safety and engineering plans, are required to replace the large high-voltage steel lattice tower that was knocked over by a pickup truck Friday afternoon. The safety and engineering were completed Friday evening, Brooks said.

“The heavy equipment, materials, and manpower needed to perform the work are either on site or en route,” he said. “We currently expect the work to be completed in time for Highway 62 to be open for the Monday morning commute. Risks to that schedule are weather and potential drilling delays due to the topography (i.e. rock).”

Crews were repairing the damage to the Tennessee Valley Authority power distribution system on Saturday after a pickup truck crashed into a large high-voltage steel lattice transmission tower on Friday, knocking it down and causing widespread electrical outages.

All four lanes of South Illinois Avenue (State Route 62) in Oak Ridge remain closed between Lafayette Drive/Scarboro Road and Bethel Valley Road while the repairs are being made. It’s not clear how long the work might take. The road remains closed because of heavy equipment, low hanging lines, and the safety of work crews, the City of Oak Ridge said Saturday.

Power to the University of Tennessee Arboretum remained out Saturday evening, the city said.

The steel lattice tower that was damaged Friday appeared to have been removed by Saturday evening, or it was no longer leaning near the roadway the way it had been Friday.

The crash was reported at Union Valley Road and South Illinois Avenue, near the UT Arboretum, at about 4:15 p.m. Friday. Three people were injured, and charges are pending against the driver.

Power was restored to all of Oak Ridge except for the University of Tennessee Arboretum after a crash knocked down a high-voltage transmission tower Friday afternoon, the city said Friday night.

The single-vehicle crash caused the tower to fall over and created widespread power outages. Many residents reported having power restored within about one to three hours, while it seemed to take longer to restore power in the southeast section of the city, closer to the crash site.

In its last update, posted at 10:10 p.m., the City of Oak Ridge said the Arboretum will be without power through Saturday.

The Tennessee Valley Authority and its work crews will blast rock in the next several weeks to build an electrical substation in east Oak Ridge. The new substation is being built before the Bull Run Fossil Plant, across the Clinch River in Claxton, closes in 2023.

The blasting was scheduled to start Thursday, January 21, but it was delayed due to weather. When it starts, the blasting work could last three weeks, TVA said in a press release. Controlled, low-charge detonations will be used to blast the rock. Blasting will occur periodically between 9 a.m. and 4 p.m., and traffic and pedestrian controls will be in place, TVA said.

The new Anderson County substation site is off Old Edgemoor Road at Haw Ridge Park, near Edgemoor Road.
