The Golden Era of American energy is upon us, and nuclear power is leading the charge.

ON THIS DAY, the Susquehanna Steam Electric Station first connected to the grid in 1984.

It’s home to ✌️ boiling water reactors that generate enough reliable electricity to power roughly 2 million homes in Pennsylvania.

Here’s to you, Mr. Robinson.

@DukeEnergy's Robinson Nuclear Plant generates enough reliable power today for more than half a million homes in South Carolina. 🏡

FACT: Several U.S. states have lifted restrictions on nuclear energy development called moratoriums.

But what exactly is a moratorium?

🤔 Which states have them?

And which states have reversed their bans?

Why so blue? 🔵

That blue glow you see surrounding a reactor core? It’s caused by a phenomenon known as Cherenkov Radiation.

✅ We're proposing a sweeping package of regulatory reforms aimed at modernizing reactor licensing, safety oversight, and siting practices for nuclear power plants. https://t.co/YgnIr7Jh1C

For over 40 years, America talked about a nuclear comeback.

@POTUS is delivering one.

One year after setting a goal to turn on three U.S. reactors by our nation’s 250th birthday, @ENERGY’s Nuclear Reactor Pilot Program is turning that goal into reality.

CRITICALITY NUMBER THREE! 🎉

On June 30, 2026, at around 11:55 PM MDT, @DeployableE’s Unity microreactor achieved initial criticality at @INL. It is the third nuclear test reactor this year to go critical under @ENERGY authorization.

Congratulations to Deployable Energy on reaching this historic milestone!

EBR-I was the first power plant to produce usable electricity through atomic fission.

It powered four 200-watt lightbulbs in 1951 and eventually generated enough electricity to light the entire facility.

We will look back in history and remember this pivot—not just in American nuclear energy—but in American energy. 

God bless President Trump for unleashing the American Nuclear Renaissance and God bless the people and companies that are making it happen.

[U.S. Department of Energy @ENERGY]

ICYMI: @SecretaryWright visited @INL to celebrate the new nuclear reactors to turn on in more than 40 years!

Thanks to President Trump unleashing the American Nuclear Renaissance, this was all made possible just in time for America’s 250th anniversary. 🇺🇸

Small pellet. Huge energy. 🤯

One uranium fuel pellet packs more power than you might guess.
