@scaryjellomj @isaiah_p_taylor Welcome to the beauty of HTGR

“the feat marks the first time a department of energy-authorized reactor has been built outside of a national laboratory.”

thanks @eva_terry02 and @Deseret! looking forward to having you back on site soon!

criticality is a family affair.

here is my nuclear engineer brother explaining to my mom and youngest brother what was happening when @valaratomics went critical today.

The Race to Criticality - June 18th, 2026 - 16 days until July 4th, 2026

@valaratomics goes critical!

The 2nd of at least three companies expected to go critical by the July 4th deadline in EO 14301.

executive order 14301 was fulfilled by @valaratomics today - fewer than 13 months after its signing.

[Governor Cox @GovCox]

BREAKING: @valaratomics' Ward 250 reactor successfully achieved criticality in Emery County, Utah, becoming the first @ENERGY-authorized reactor built outside a national laboratory.

This achievement is a testament to the innovators, builders, and public servants working to strengthen America’s energy future. Utah is proud to be at the forefront of the next generation of nuclear technology.

@DeployableE announces they received FDSA from the DOE earlier this month and jump further up the list!

President Trump signed EO 14301 nearly a year ago today. Since then, 11 teams of engineers have been racing to achieve the President's goal: criticality in three advanced reactors outside of the national labs by July 4th.

Grateful to be part of it as we enter the final inning!

[Valar Atomics @valaratomics]

Last Thursday, we paused site work and opened up Ward250 to our community in Emery County.

Over 300 neighbors joined us for an evening of nuclear reactors and BBQ, and lots of people learned about how nuclear works for the first time.

Team Valar is grateful for Emery County!

So awesome to sit down with Alex on the Upstarts podcast! Thank you for having me

There’s no group in the world like America’s warfighters.

[Valar Atomics @valaratomics]

Today, we’re exited to partner with the Department of War and Department of Energy on Operation Windlord. Three C-17s will be transporting our Ward250 reactor from March ARB to Hill AFB.

Here’s a peek at what it took to bring this operation to life. (Part 1)

[DOW Rapid Response @DOWResponse]

.@DEPTOFWAR is proudly partnering with @ENERGY to advance America's nuclear energy dominance as part of President Trump's Executive Order.

Today, we are airlifting a next-generation nuclear reactor—HISTORIC!

[Department of War 🇺🇸 @DeptofWar]

We’re advancing President Trump’s executive order on nuclear energy.

Moments from now, we will airlift a next-generation nuclear reactor.

[Charlotte W. Nazarian @CWNazarian]

idk maybe it’s something in the air but today just feels like a great day to move this reactor to utah
