Question

In the reactor of a nuclear power plant, name the material which is used
(a) as a moderator
(b) to absorb radiations
(c) in the fuel rods
(d) in the control rods
(e) to carry away heat

Answer 1

Answer:

The fuel rods: source of enriched Uranium fuel that undergoes fission reactions. The moderator: the fuel rods are encased in the moderator (graphite is sometimes used) and help the fission reaction to proceed efficiently. The control rods: normally made of Boron, these help control the fission reaction.
