* (idiomatic, nuclear physics, uncountable) A hypothetical kind of catastrophic failure in which a nuclear reactor melts through the floor of its containment system and (if on land) penetrates the Earth's surface, continuing downward as if (from a Western Hemispheric point of view) traveling through the planet toward China.

Dr. Lowell: If the core is exposed for whatever reason, the fuel heats beyond core heat tolerance in a matter of minutes. Nothing can stop it. And it melts down right through the bottom of the plant, theoretically to China. But of course, as soon as it hits ground water, it blasts into the atmosphere and sends out clouds of radioactivity.

"See any evidence of a hull fracture?" "No," the ensign answered, "just the two burn-throughs. I wonder what went wrong?" "A for-real China Syndrome. It finally happened to somebody." Ames shook his head. If there was anything the navy preached about reactors, it was safety. "Get the transducer against the hull. We'll see if anybody's alive in there."
