A scram or SCRAM is an emergency shutdown of a nuclear reactor effected by immediately terminating the fission reaction. It is also the name that is given to the manually operated kill switch that initiates the shutdown. In commercial reactor operations, this type of shutdown is often referred to as a "scram" … See more In any reactor, a scram is achieved by inserting large amounts of negative reactivity mass into the midst of the fissile material, to immediately terminate the fission reaction. In See more Most neutrons in a reactor are prompt neutrons; that is, neutrons produced directly by a fission reaction. These neutrons move at a high velocity, so they are likely to escape … See more • Nuclear technology portal • The China Syndrome – 1979 US drama neo-noir thriller film by James Bridges • Iodine pit – Problem in nuclear reactor start-up See more Scram is usually cited as being an acronym for safety control rod axe man; however, the term is probably a backronym. The actual axe man at the first chain-reaction was Norman Hilberry. In a letter to Raymond Murray (January 21, 1981), Hilberry wrote: See more • NRC Glossary: Scram • "Scram Switch" entry in The Jargon File See more WebThe BWR is characterized by two-phase fluid flow (water and steam) in the upper part of the reactor core. Light water (i.e., common distilled water) is the working fluid used to conduct heat away from the nuclear fuel. The water around the fuel elements also "thermalizes" neutrons, i.e., reduces their kinetic energy, which is necessary to ... bristol city women\u0027s tickets
