THAT’S IT?

This is what 20 years’ worth of used nuclear fuel looks like safely stored at the former Maine Yankee nuclear plant.

The plant generated 119 billion kilowatt hours of reliable power from 1972-1996, which is enough to power half a million homes each year.

Morning, Monticello! ☀️

Monticello Nuclear Generating Plant near Minneapolis generates more than 10% of Minnesota’s electricity.

That’s enough power for more than 500,000 homes.

TRIFECTA: Browns Ferry is home to 3️⃣ boiling-water reactors that produce up to 3,400 megawatts of power in Alabama.

Browns Ferry is Tennessee Valley Authority's first nuclear power plant and it generates enough electricity to power more than 2 million homes and businesses in the Tennessee Valley. 🏘️

Unit 1 first connected to the grid on this day in 1973!

DID YOU KNOW? 🤔 Colorado’s only commercial reactor was a high-temperature gas-cooled reactor.

Check out this throwback photo of the refueling floor at the Fort St. Vrain Generating Station in 1972.

The reactor entered operation in 1979 and, at the time, was the only commercial high-temperature gas-cooled reactor in the U.S.

The reactor was fueled with 1,482 hexagonal fuel elements made of graphite and generated 330 megawatts of power.

The plant was taken offline back in 1989 for decommissioning.

The site was later converted to combined-cycle natural gas plant.

BUILDING BLOCKS: SGL Carbon’s $100M facility in St. Mary’s, PA, is ready to produce graphite blocks for X-Energy's Xe-100 small modular reactor.

This will support X-energy’s first SMR deployment at Dow’s Project Long Mott in Texas under the U.S. Department of Energy's Advanced Reactor Demonstration Program.
