Scram as the original and mostly likely accurate basis for the use of scram in the technical context. A persistent alternative explanation posits that scram is 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. It could also stand for "Safety Control Rods Activation Mechanism" or "Control Rods Actuator Mechanism". Both of these are probably backronyms from the original, non-technical usage. In any reactor, a SCRAM is achieved by inserting large amounts of negative reactivity mass
Enrico Fermi Nuclear Generating Station a companion unit identical to Fermi 2. It was ordered in 1972 and cancelled in 1974. See DOE data page 67 and WNA Fermi 3 data. In September 2008, Detroit Edison filed an application with the Nuclear Regulatory Commission (NRC) for a Combined Construction and Operating License (COL) for a third reactor. The new unit is supposed to be built on the same site, slightly to the southwest of Fermi 2. The reactor design selected is the 1,550 MWe GE-designed passive Economic Simplified Boiling Water Reactor (ESBWR). Review of the 17,000-page application could take four years, after which construction could
