What is a nuclear SCRAM?

384 viewsOtherPhysics

In the movie *Shin Godzilla*, the humans came up with a blood coagulant and a plan to inject it into Godzilla in order to freeze him. It’s mentioned in the film that doing so would force him to perform a nuclear SCRAM since he’s fueled by an internal nuclear reactor. The coagulant works, shutting down his circulation (which is his cooling system), and causes him to freeze.

But what IS a nuclear SCRAM? i’ve looked it up before, but I just can’t seem to make heads or tails of it.

ELY5: you know how fire needs fuel (wood) and oxygen, and a fire extinguisher takes away the oxygen? A nuclear reactor needs fuel (uranium) and neutrons. The SCRAM takes away the neutrons.

That acronym is ringing my “Too cute” alarm, aside from tradition is there any period sources that cite it as the definition of SCRAM ?
