Description : What is the function of coolant?
Last Answer : Heat is absorbed by the coolant that is produced in the reactor. Typical coolants are water, carbon dioxide gas or liquid sodium.
Description : What is the function of shielding?
Last Answer : Shielding prevents radiations to reach outside the reactor. Lead blocks and concrete enclosure that is strong enough of several meters thickness are used for shielding.
Description : What is the function of control rod in nuclear reactor?
Last Answer : These rods absorb neutrons and stop the chain reaction to proceed further.. Some control rods are made from an alloy of silver and cadmium. Some are made from boron mixed with iron or carbon. ... happens and the reactor gets colder.The control rods can used to shut the reactor down completely.
Description : Define water as moderator.
Last Answer : Neutrons from fission have very high speeds and must slowed greatly by water moderation to maintain the chain reaction.
Description : what is function of Moderator in nuclear reactor?
Last Answer : The moderator is a material which slows down the speed of the neutrons. The moderator is usually made from water but some reactors use graphite also.Neutrons released from the chain reaction must be ... moderator slows the neutrons down so that they can be captured and keep the chain reaction going.
Description : Which is the nuclear fuel used ?
Last Answer : The commonly used fuels are Uranium, Plutonium or Thorium. It can be U-235, U-238, Pu-236 or Th-232. Uranium is mostly preferred as it has high melting point.
Description : Name the different components of nuclear reactor?
