Question

A device in which electricity is produced by the process of controlled nuclear fission reaction is called
(a) nuclear chain reaction
(b) hydel power plant
(c) nuclear reactor
(d) thermal power plant

Answer 1

The correct answer is option (c) nuclear reactor.

• A nuclear reactor is a device in which electricity is generated by a controlled nuclear fission reaction process. A nuclear reactor, formerly known as a nuclear atom, is a tool used to initiate and control the reaction of a nuclear chain or nuclear fusion.
• Nuclear reactors are used in nuclear power plants to generate electricity and run at sea. The water in the middle is heated by a nuclear explosion and then thrown into the tubes inside the heat exchanger. Those tubes heat up a different water source to form steam. The smoke then turns on the electric generator to generate electricity. The core water cycles return to the reactor for heating and the process is repeated.

Answer 2

Answer:

The answer is (c) the nuclear reactor

Explanation:

A nuclear reactor is a piece of equipment that is used to carry out controlled nuclear fission.

• Slow neutrons are utilized in nuclear reactors for nuclear fission.
• Usually, $U_{235}$ is used as nuclear fuel.
• Slow neutrons are captured when they are bombarded with fuel, and fission occurs by releasing energy.
• Moderators such as heavy water and graphite powder are employed to slow down the fast-moving neutrons.

Hydropower is used to generate energy in a hydel power plant. A thermal power station, on the other hand, is a power plant that converts heat energy into electricity.
