90. Life Imitates Art?

The ______ _____ is a notion that refers to a possible extreme result of a nuclear meltdown in which molten reactor core products breach the barriers below them and flow downwards out of containment.

In 1971, nuclear physicist Ralph Lapp used the term to describe the burn-through of the reactor vessel, the penetration of the concrete below it, and the emergence of a mass of hot fuel into the soil below the reactor.

The dangers of such a hypothetical accident were publicized by the 1979 film, which had the same name as the phrase. The film was released on March 16, 1979, just twelve days before the real-life events at Three Mile Island, Pennsylvania.

What phrase?
