Question

In nuclear reactor, cadmium rods are used as which of the following?
A) Fuel B) Moderator C) Controller D) Lubricant

Answer 1

Explanation:

cadmium rods are used as (c) controller

Answer 2

Answer:

cadmium rods are used as a controller.

Cadmium rods are used in a nuclear reactor for regulating the power level of the reactor. Cadmium rods are used in nuclear reactors to control the fission rate of radioactive material used. It is capable of absorbing many neutrons without fissioning themselves.

Heavy water, graphite etc. are used as moderator.

Explanation :

A neutron moderator is a medium that reduces the speed of fast neutrons, thereby turning them into thermal neutrons capable of sustaining a nuclear chain reaction involving uranium-235.

Heavy water can serve as a neutron moderator in a nuclear reactor, which slows down fast particles and encourages the fission reaction
