Detailed explanation-1: -Cadmium rods are used as control rods as they are capable of absorbing neutrons without themselves fissioning.
Detailed explanation-2: -Control rods are used in nuclear reactors to control the rate of fission of the nuclear fuel – uranium or plutonium. Their compositions include chemical elements such as boron, cadmium, silver, hafnium, or indium, that are capable of absorbing many neutrons without themselves decaying.
Detailed explanation-3: -3. Which of the following may not need a moderator? Explanation: Fast Breeder Reactor may not need a moderator.
Detailed explanation-4: -A rod, plate, or tube containing a material such as hafnium, boron, etc., used to control the power of a nuclear reactor. By absorbing neutrons, a control rod prevents the neutrons from causing further fissions.
