Question

Define the following components used in nuclear reactors :
1. fuel
2. moderator
3. control rod
4. coolant
5. protection wall​

Answer 1

Answer:

1.Nuclear Fission Creates Heat

Reactors use uranium for nuclear fuel. The uranium is processed into small ceramic pellets and stacked together into sealed metal tubes called fuel rods. ... The heat created by fission turns the water into steam, which spins a turbine to produce carbon-free electricity.

Explanation:

Answer 2

Components of a nuclear reactors

1. Fuel : A fissile material is used as the fuel. The commonly used fuel material is uranium.
2. Moderator : A moderator is used to slow down the high energy neutrons to provide slow neutrons. Graphite and heavy water are the commonly used moderators.
3. Control Rod : Control rods are used to control the number of neutrons in order to have sustained chain reaction. Mostly boron or cadmium rods are used as control rods. They absorb the neutrons.
4. Coolant : A coolant is used to remove the heat produced in the reactor core, to produce steam. This steam is used to run a turbine in order to produce electricity. Water, air and helium are some of the coolants.
5. Protection wall : A thick concrete lead wall is built around the nuclear reactor in order to prevent the harmful radiations from escaping into the environment.
