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.
In: Physics
A SCRAM is an emergency shutdown, as opposed to a planned shutdown.
In a SCRAM, the reactor trip breakers are opened which causes the control rods to drop into the fuel assemblies for a PWR, and rise into the fuel assemblies for a BWR. The result is the same: the reactor is for all intents and purposes not fissioning anymore.
