US Tennessee Valley Authority (TVA) said unit 2 of its Browns Ferry NPP in Alabama had resumed operation on 22 April, following the completion of a scheduled maintenance and refuelling outage. This included the largest scope of turbine deck work since original construction, with large-scale replacements of major components on all three low-pressure turbines, including new rotors, inner casings, steam piping and bellows and turbine supervisory instruments. This will enable the unit to generate an additional 7MWe.

Framatome has announced that 3D-printed fuel assembly channel fasteners manufactured at the US Department of Energy's Oak Ridge National Laboratory (ORNL) in a joint project with Tennessee Valley Authority are to be loaded into a US commercial reactor for the first time. The project is part of the laboratory's Transformational Challenge Reactor programme. The four components will be loaded into TVA's Browns Ferry nuclear power plant in early 2021.

The NRC staff determined that TVA could safely increase the reactor’s output, primarily through more accurate means of measuring feedwater flow. NRC staff also reviewed the TVA evaluations demonstrating that the plant’s design can safely handle the increased power level.

The power uprate for Unit 2 will increase the unit’s generating capacity from approximately 1,223 MW to 1,240 MW, the NRC said. TVA intends to implement the uprate by mid-December 2020.

Scheduled refuelling and extensive planned maintenance work has begun at the Sequoyah-2 nuclear power plant in the US state of Tennessee, two weeks later than originally planned because of the Covid-19 epidemic.

“To keep Sequoyah nuclear unit 2 generating low-cost, carbon-free energy, the team at the plant is performing a scheduled maintenance and refuelling outage,” plant owner and operator Tennessee Valley Authority said on social media.

“During these trying times, additional safety procedures are in place, including social distancing and wearing masks.”

Last month TVA said it had taken the “precautionary step” of delaying planned outages at Sequoyah-2 and Watts Bar-1 by two weeks due to the coronavirus pandemic.

The Tennessee Valley Authority (TVA) is to collaborate with the University of Tennessee, Knoxville (UT) to evaluate the development of a new generation of advanced nuclear reactors at TVA's Clinch River site. TVA has an early site permit from the US Nuclear Regulatory Commission for two or more small modular reactors at the site but has not yet taken a decision to build.

US utility Tennessee Valley Authority took the “precautionary step” of delaying planned outages at the Sequoyah-2 and Watts Bar-1 nuclear power plants this spring by two weeks due to the coronavirus pandemic, TVA spokesman Jim Hopson was quoted in media reports as saying.

S&P Global Platts said it is the first announced delay to a US outage.

“For competitive reasons, we don’t provide specifics on our outage dates,” Mr Hopson Hopson said. “However, both of the outages were previously planned for this spring and will begin two weeks later than originally scheduled.”

According to a March 20 letter from the Nuclear Energy Institute to the US Department of Energy a refuelling outage for the 1,139-MW Sequoyah-2 unit was originally scheduled to start in late March while the 1,123-MW Watts Bar-1 unit was set to begin an outage in the middle of April.

US utility Tennessee Valley Authority (TVA) and the US Department of Energy’s Oak Ridge National Laboratory (ORNL) have signed an agreement to evaluate economically a new generation of flexible, cost-effective advanced nuclear reactors, including small modular reactors (SMR).

ORNL said in a statement that the agreement will focus on ways to improve the economic feasibility of potentially licensing, building, operating and maintaining one or more advanced nuclear reactors.

The statement said advanced reactors offer the potential of lower-cost carbon-free energy through reduced construction times and greater operational flexibility.
