reactors also have a flawed control rods design in which during rapid scrams, the graphite reaction enhancement tips of the rods would displace water at the...

the reactor power level to be controlled via the gradual, mechanical movement of control rods. Typically, control rods contain neutron poisons (substances...

isotope, samarium-149, is a strong neutron absorber and so is added to control rods of nuclear reactors. It also forms as a decay product during reactor...

modern rods are usually more elastic and generally have the line stored in a reel mounted at the rod handle, which is hand-cranked and controls the line...

nuclear plants have some form of reactor protection system. Control rods are a series of rods that can be quickly inserted into the reactor core to absorb...

assembled into fuel rods. Reactivity is controlled by control rods that can be inserted into the reactor from above. These rods are made from a neutron...
