Using a new boiling detector at the TREAT facility, researchers captured critical heat flux - the point where normal boiling turns into dangerous vaporization. The entire experiment lasted one second. Slow-motion footage shows exactly where the system breaks down. This data helps engineers design safer reactors and test accident-tolerant fuels for next-
