The largest public power company in the U.S. is launching a program to develop and fund new small modular nuclear reactors as part of its strategy to dramatically reduce greenhouse gas emissions.
The board for the Tennessee Valley Authority on Thursday authorized the program to assess moving forward with new nuclear technology, with up to $200 million to be spent for the first phase. The TVA wants the technology to be available to help power the grid in the 2030s if it proves cost-effective and necessary, and the Nuclear Regulatory Commission approves. The board met at Western Kentucky University in Bowling Green, Kentucky.
The federally owned utility provides electricity to seven states. It has the first U.S. permit for a suitable site for small modular reactors in Oak Ridge, Tennessee, at the Clinch River Nuclear Site. By 2050, it hopes to hit its goal of net-zero emissions, which means the amount of greenhouse gases produced is no more than the amount removed from the atmosphere.
"Our objective isn't to build one nuclear plant," TVA President and CEO Jeff Lyash said in an interview. "Our objective is to reach net zero carbon, to support economy-wide decarbonization, and to do it at a price and a level of reliability that people can count on. And this is a part of doing that."
A recent Associated Press survey of the energy policies in all 50 states and the District of Columbia found that a strong majority—about two-thirds—say nuclear, in one fashion or another, will help take the place of fossil fuels. Roughly one-third of the states and the District of Columbia have no plans to incorporate nuclear power in their green energy goals, instead leaning heavily on renewables to try to stave off the worst effects of a warming planet.
The split over nuclear power in U.S. states mirrors a similar debate unfolding in Europe, where countries including Germany are phasing out their reactors while others, such as France, are sticking with the technology or planning to build more plants. The head of the U.N. nuclear agency said in November that he sees atomic power playing a key role in balancing climate concerns and the world's energy needs.
Lyash said the TVA can reduce carbon emissions by about 80% using solar and wind power, existing nuclear plants and hydroelectric dams, and by reducing demand through energy efficiency efforts, without sacrificing reliable, resilient, low-cost power.
But the smaller nuclear reactors that companies are developing now are crucial to getting the rest of the way and increasing electricity production, along with other new technologies, he added. The utility now operates three nuclear plants—the nation's third largest nuclear fleet—to supply more than 40% of the region's energy.
Lyash told the board Thursday that for the Clinch River site, the TVA is focused on GE Hitachi's design for a small modular reactor that uses light water like all U.S. commercial reactors. The TVA is also collaborating with Kairos Power to build a test reactor, a demonstration project that wouldn't be for commercial use, in Oak Ridge.
The Union of Concerned Scientists has cautioned that nuclear technology still comes with significant risks that other low-carbon energy sources don't, including the danger of accidents or targeted attacks for both the radioactive waste and the reactors, and the unresolved question of how to store hazardous nuclear waste.
Grant Smith, a senior energy policy adviser at the Environmental Working Group, said small reactors are going to be a "total financial debacle" because the cost of nuclear power never comes down, with costs and risks shifted to ratepayers.
"You really don't need them," he said in an interview. "Why keep dumping money into a technology that has been a financial disaster from the beginning?"
The TVA had plans decades ago to build 17 large reactors at seven sites. The utility sank more than $8 billion in the 1970s and 1980s into 10 nuclear reactors that were canceled before they were finished—scrapping most of what then was the nation's most costly and ambitious nuclear program.
Lyash said they're now taking a far more conservative approach: They're not launching into a program to build multiple reactors on multiple sites because they've learned many lessons over 50 years. If one reactor can't be planned and built on schedule and on budget, they won't scale up, he added.
The initial funding will be used for the design, licensing and project development to potentially build GE Hitachi's reactor.
The NRC has approved just one of the new, small modular reactor designs: from an Oregon company called NuScale Power, in August 2020. Several other companies are planning to apply for their designs. That includes a project by Bill Gates' company, TerraPower, in Wyoming, the nation's largest coal-producing state.
“small modular nuclear reactors”
About time, only been saying this for over 30 years.
It will take 30 years for the first one................
Only ten years late to the party.
They should have started these 30 years ago. Same with water desalination plants. Corporation against Corporation plus politicians are what cause these hold ups to do the right things. Product lobby against product lobby. Big Oil against Nuclear in this case.
It is not at all about the environment as they claim. Because a bunch of small, safer, easier to control plants is much better for the environment and stable supply than one big plant that is completely uncontrollable and dangerous if it melts down.
Union of Concerned Scientists is pretty much KGB. “Nuclear Winter,” for instance, was the work of Sergei Tretyakov and the Red Banner Institute. UCS knew that, and even invited Soviet observers by sat link to participate in Carl Sagan’s 1983 conference to promote the theory. KGB asset Paul Crutzen won a Nobel Prize for his work on ozone depletion, but was a key force behind UCS.
And what do they propose to do with all the radioactive waste, give it to Space X?
From a system wide perspective, smr’s would be the way to go. Decentralize the grid and reduce energy waste in transmission over long distances. We’ve been building smr’s for naval vessels for fifty years, we know how to do it if the obstructionists would just stand back. And unlike large reactors smr’s could be virtually mass produced on demand. The list of opponents really tells the tale— left wing radicals.
They oppose ANYTHING with the word ‘nuclear’ in the title................
They will crank up the protest machine and start spewing crap about a CHERNOBYL IN EVERY NEIGHBORHOOD!
WE MUST PROTECT THE CHILDREN!
THERE WILL BE CANCERS EVERYWHERE!......etc, etc, etc.................
Well, the Ford Fusion certainly was...
At least for 14 years...
However, getting back to thorium reactors, I thought that China, Japan, or S. Korea had something going on??
I always find that funny.

Once the factory is up and rolling Rolls says 500 days from ground breaking to busbar.

Give it to the French, Russians or Koreans have them reprocessed it into more fuel and put the 4% that is actual waste down a borehole 4000 meters into solid Granite fill the top 3000 meters with concrete and sleep well at night.
Better yet buy 4 sections of land in central Texas over the granite batholith I’ll do the Geological survey and geosteer the wells into their 4km total depth. My LLC will take possession of the 4 sections and I will personally live on top right in the middle of the borehole field going bore hole to borehole with the rigs drilling the holes. In addition to my services as a consulting geo a trust will be set up with a million dollars a year indexed to the inflation rate for continuing Geological monitoring for the next 100 years. With 4 sections of land once the borehole are drilled and filled I’ll run cattle over the tops of them. I’d be happy as a clam living right on top of bore holes drilled every 50 meters apart in a grid pattern then plugged with miles of concrete.
Waste is a political problem not a scientific one. If the dot gov is reading my above offer is real I am a geologist with decades of experience with disposal boreholes of all manor of liquid wastes solid wastes are easy peasy.
Because it is!....................
