Brief

Isaiah P. Taylor recounts that on 2026-08-03 Valar Atomics planned their first Ward250 criticality with a large Sequoia partnership presence; procedural errors forced a late-night stand-down and a rewrite. Liam Corrigan canceled his flight, stayed, and later witnessed the Ward250 criticality, publicly praising the team's execution.

Why it matters

On 2026-08-03 @isaiah_p_taylor reported that during Valar Atomics' first planned Ward250 criticality attempt they discovered several procedural errors, stood down late that night, and rewrote the procedure.

Key details

  • Liam Corrigan (@lmcorrigan1) canceled his flight, said 'I'm not leaving', stayed with the team and experienced Ward250 criticality with them for the first time; he later tweeted that their execution 'parallels that of our nation's proudest technological accomplishments.'
Source evidence

Fun fact, the day we planned to go critical for the first time, we had a big group of the Sequoia partnership out. We got a few aspects of the procedure wrong and had to stand down late that night to rewrite. I assumed everyone would go home.

Liam was like “I’m not leaving”

cancelled his flight and everything the following day

then experienced Ward250 criticality with us for the first time :)

Love this partnership

Massively earned by @isaiahptaylor and the entire @valaratomics team. Their execution parallels that of our nation’s proudest technological accomplishments and it’s an honor to witness this team deploy.
