re: #78 Rightwingconspirator

Good post, I would have thought the term to mean a core actually melting in small part or more.

It’s really all about containment. Keep that intact and all else is relatively acceptable.

True. So long as it doesn’t breach the containment vessel, then any radioactivity will be (hopefully) limited to the facility itself. Not the most cheerful scenario, but it beats the alternatives.
