Wikipedia
Scram

A scram or SCRAM is an emergency shutdown of a nuclear reactor, though the term has been extended to cover shutdowns of other complex operations, such as server farms. In commercial reactor operations, this type of shutdown is often referred to as a "SCRAM" at boiling water reactors (BWR), and as a "reactor trip" at pressurized water reactors (PWR). In many cases, a SCRAM is part of the routine shutdown procedure as well.

The term is usually cited as being an acronym for safety control rod axe man, which was supposedly coined by Enrico Fermi when the world's first nuclear reactor was built under the spectator seating at the University of Chicago's Stagg Field, but NRC Historian Tom Wellock calls the axe-man story "a bunch of baloney". It could also stand for " Safety Control Rods Activation Mechanism" or " Control Rods Actuator Mechanism", both of which are probably backronyms. "Scram" is American English slang for leaving quickly and urgently, which has been cited as the original basis for the use of scram in the technical context.

Scram (video game)

Scram is an Atari 8-bit family game written by Chris Crawford and published by Atari in 1981. It involves involving a scram, or emergency shutdown of a nuclear reactor. Written in Atari BASIC, Scram uses differential equations to simulate reactor behavior. The player controls the valves and switches of a nuclear reactor directly with the joystick.

An unrelated game with the same name was written for the DEC Alpha.
