This Abbreviation SCRAM stands for Safety Control Rod Axe Man. The very early nuclear reactors were equipped with a safety control rod that is kept high above and away from the reactor core. This safety control rod was attached to a rope passing over a wheel and going down where the end of the rope is fixed at a lower point. Then a man with axe is always keeping alert and watching the reactor safe operation. In case of emergency, he cuts the rope with the axe and the safety control rod drops by gravity inside the reactor core and stops the nuclear chain fission reaction and consequently stops reactor operation.

A SCRAM refers to what type of situation?
A SCRAM typically refers to an emergency shutdown of a nuclear reactor to prevent overheating and potential meltdown. It stands for "safety control rod axe man", referring to the quick insertion of control rods to halt the nuclear chain reaction.
Why cant a nuclear power plant explode like a nuclear bomb?
A fission bomb explodes because of a sudden assembly (driven by conventional explosives) of a very supercritical mass of fissile material, followed by a precisely timed neutron pulse at the optimal point of supercriticality.A fission reactor cannot do this, for the following reasons:most fission reactors do not contain fissile material, only fissionable materiala fission reactor has no mechanism for sudden assemblyof a very supercritical massfission reactors operate exactly at critical, so the reaction neither dies out nor risesfission reactors use a continuous neutron source at startup that is removed once the reactor is running, not a precisely timed pulsed neutron source like used in fission bombsif a fission reactor using fissile material did go supercritical enough (without the automatic SCRAM system shutting it down first) to get a small nuclear yield, it would be a fizzle yield only capable of melting the core and thereby instantly dissembling the supercritical massDefinitions:Fissionable material - material capable of sustaining fission, but only in presence of a moderator to slow neutrons to prevent their capture by Uranium-238 or other isotopes with large capture crosssections for fast neutronsFissile material - weapons grade material requiring no moderator and capable of fast fission. required for both bombs and fast breeder reactors.
What is the purpose of the control rod?
The control rods in a nuclear reactor are simply neutron absorbers which can be raised or lowered, this enables the reactor to be maintained at criticality with the chain reaction proceeding at a steady rate. The reactor loses reactivity between refuellings which are probably every two years, so the control rods have to be slowly withdrawn to compensate. They are also fully inserted very quickly should the safety instruments require it, and the reactor then stays shutdown. (Reactor scram or trip)
What would happen if you pulled the control rods out of a nuclear plant?
If you pulled the rods out regardless of the rapid rise in power, the reactor high flux protection safety system would see the rapid rise in power and would scram or trip the rods back in, thus bringing the power down to zero very quickly.
How could you fool the scram bracelet?
It is illegal to tamper with an electronic monitoring device like a scram bracelet. Trying to remove or disable it can lead to serious legal consequences, including additional charges and extended monitoring. It's important to comply with the terms of your monitoring and address any issues through the appropriate legal channels.
What does scram mean for a nuclear reactor?
In dealing with a nuclear reactor SCRAM stands for Safety Control Rod Activator Mechanism. Nuclear reactors can be quite dangerous.
What has the author W E Kastenberg written?

What is the Luhya word for the English word scram?
The African Luhya word for the English word 'scram' is "lwanaa".
What happens if nuclear reactor leaks?
If a nuclear reactor leaked you would have to evacuate the area around the plant and you would attempt to stop the leak and probably depending on the severeity level of the situation you may need to 'SCRAM' the reactor.

Does a scram bracelet detect meth?
No. But if you have a SCRAM, you may be tested randomly for drugs and because you have a SCRAM, you are already in trouble and you don't need more.
