a steel or aluminum rod that can be moved up or down to control the rate of the nuclear reaction
a rod made of a chemical element capable of absorbing many neutrons without decaying themselves
a rod, plate or tube containing a material such as hafnium, boron, etc
rods of cadmium or boron which can be placed in or removed from the core of a nuclear reactor to control the number of neutrons causing a chain reaction by absorbing neutrons.
A rod containing material that absorbs neutrons; used to control or halt nuclear fission in a reactor.
Devises normally made from rod or bar installed to limit the travel of each individual bellows in a universal expansion joint to the rated motion. Control rods are not designed to react pressure thrust - see Tie Rods.
a device that absorbs neutrons. When inserted into the nuclear fuel, the rods stop the fission process, which shuts down the reactor.
A control rod is a rod made of chemical elements capable of absorbing many neutrons without fissioning themselves. They are used in nuclear reactors to control the rate of fission of uranium and plutonium. Chemical elements with a sufficiently high capture cross section for neutrons include silver, indium and cadmium.
