TVA developing plans for 20 small nuclear reactors to power Tennessee Valley by 2050

Oct. 26—To decarbonize and electrify America's economy, the head of the nation's biggest public power utility thinks several hundred new nuclear reactors may be needed in the next generation, including 20 or so new smaller reactors across the
In a talk to business investors and nuclear power leaders this week,
"I have no interest in building just one reactor," Lyash said during a presentation to the
As cars shift from gasoline to battery power and homes and industries shift away from natural gas and propane to electricity use, Lyash projects electricity demand in the
To replace coal, natural gas and other fossil fuels, Lyash said more nuclear power will be essential, especially to provide reliable, continuous power when the sun doesn't shine for solar generators or the wind doesn't blow for windmills to generate electricity.
"We have to preserve, extend and leverage the existing nuclear fleet, and we have to have new nuclear if we are going to solve these problems," Lyash said.
NEED FOR NUCLEAR
"When we look at the energy crisis we are in today, we see danger and opportunity," Albright told the
But over the past four decades,
Lyash said he is hopeful the next generation of advanced nuclear plants will be more cost-effective and efficient to build and operate, and he added
The proposed new small modular reactors have yet to be fully designed and licensed, Gunter said in a phone interview.
"SMR presently stands for 'small mirage reactors,'" he said. "The technology is not ready, and given the history of the previous three generations of nuclear power, the industry refuses to recognize the common failure of nuclear power and the inability to meet cost and time schedules."
Gunter said the new advanced reactors being built at Plant Vogtle in
Among more than 30 initial applications to build one of the Westinghouse AP1000 reactors, only the two units at Vogtle are still being built, Gunter said.
"For these so-called advanced nuclear units now being talked about, there are no guarantees that they have learned any lessons from the previous failures and the inability to control costs," Gunter said.
Lyash, a former nuclear plant operator who has headed the biggest public utilities in both
"We want to be very disciplined in our approach," he said. "These units have to be delivered on schedule and on budget. And when they come into service, they have to operate at 95% capacity factor and do so safely."
Unlike previous generations, the small modular reactor will be fully designed before construction begins, and its modular design will allow key components in each reactor to be built in a factory setting and shipped to the reactor site.
"We've got to earn our place at the table with a competitive price — stamping out plants on budget and on time,"
GE Hitachi is working with several utilities on its BWRX-300 small modular reactor, including both
As the 10th evolution of the boiling water reactor, the BWRX-300 represents the simplest and most innovative boiling water reactor design since
