In most reactor designs, as a safety measure, control rods are attached to the lifting machinery by electromagnets, rather than direct mechanical linkage. This means that in the event of power failure, or if manually invoked due to failure of the lifting machinery, the control rods fall automatically, under gravity, all the way into the pile to stop the reaction. A notable exception to this fail-safe mode of operation is the BWR, which requires hydraulic insertion in the event of an e… WebJul 1, 2002 · Conference: Preliminary Investigation of an Optimally Scramming Control Rod for Gas-Cooled ReactorsPreliminary Investigation of an Optimally Scramming Control Rod for Gas-Cooled Reactors
