.@SecretaryWright: “The plan is to take 15 reactors at 8 different locations and uprate them. Meaning the plant behind me would get another 150MW of power output...

Significantly more energy, puts downward pressure on rates, allows more manufacturing, more jobs to be created."

[U.S. Embassy Singapore @USEmbassySG]

Energy security powers the digital economy and drives future growth. At Singapore International Energy Week 2026, Ambassador Sinha delivered welcome remarks on American energy abundance and nuclear technology leadership.

Assistant Secretary for Nuclear Energy Ted Garrish and nuclear expert Dr. Kirsten Cutler joined a fireside chat sharing their insights on the role of U.S.-Singapore cooperation in strengthening energy security and the deployment of reliable American energy solutions.

The Energy Department is delivering on @POTUS' Executive Order to unleash the American Nuclear Renaissance!

These investments will strengthen our grid and lower energy costs!

[Energy Dominance Financing @DOE_EDF]

@ENERGY commits up to $5B for nuclear uprates in IL, MD, & PA—adding 1,100 MW of reliable power for 930K+ homes.

Constellation’s upgrades boost grid reliability & support America’s energy dominance. https://t.co/oJMDeKvwJ5

I recently visited @BWXT to see firsthand how they’re supporting critical missions across the United States, including Project Pele—a deployable nuclear microreactor.

The nuclear renaissance is here thanks to President Trump and it’s incredible to see the work being done to help make this a reality.

METL ROCKS 🤘: @Argonne is home to the largest liquid metal test facility in the U.S.

It’s used to test small and medium-sized components that will be used in sodium-cooled fast reactors.

4️⃣ fast facts you didn’t know about nuclear energy.

[Office of Nuclear Energy | US Department of Energy @GovNuclear]

Fission and fusion are two physical processes that produce massive amounts of energy atoms. They yield millions of times more energy than other power sources through nuclear reactions but differ in 5 key ways.

NATION’S FIRST MICROREACTOR? This is PM-1, a 1 MWe portable reactor that powered large radars and provided space heat for the Sundance Air Force Station in Wyoming in the 1960s.

Hey HFIR 👋: The High Flux Isotope Reactor provides one of the world’s highest steady-state neutron fluxes to help researchers predict how materials will perform when irradiated.

It’s also one of the nation’s top facilities for making medical, industrial, and research isotopes.
