Valar Atomics nuclear plant.

Valar Atomics activated its Ward 250 nuclear microreactor on stage during a live event, where it announced its partnership with Nvidia to power an AI factory. The company shared a portion of the live stream on its LinkedIn account, where one of its team members plugged an Nvidia RTX desktop unit into the reactor, which was then turned up to 37% of its full power to activate the Blackwell-powered PC.

Its CEO, Isiah Taylor, claims that anyone can go to the website as long as the reactor is running.
