Question

The Nuclear reactor at Kaiga is a :
A. Research rector
B. Fusion reactor
C. Breeder reactor
D. Power rector

Answer 1

Hint: This problem can be solved by good knowledge of nuclear reactors. Basic principle of nuclear power plants is based on the law of conservation of energy. It converts thermal energy into electrical energy. Radioactive elements which decay themselves and remove the lots of energy that we can be utilised for different purposes. One used to make electricity.

Formula used: Typical Nuclear fission reaction-: In which neutrons \[{}_0^1n\] collide with \[{}_{92}^{235}U\]. It gives \[{}_{56}^{144}Ba\] and \[{}_{36}^{94}Kr\] as well as three neutrons. These three neutrons initiate the further chain.
${}_0^1n + {}_{92}^{235}U \to {}_{56}^{144}Ba + {}_{36}^{94}Kr + 3{}_0^1n$

Concept used:
Basic principle of a nuclear power plant is based on the law of conservation of energy. It converts thermal energy into electrical energy.
Nuclear energy can be get by two method
By fusion of radioactive elements.(uncontrolled)
By fission of radioactive elements.(controlled)
Radioactive elements which decay themselves and remove the lots of energy that we can be utilised for different purposes. One used to make electricity.
Radioactive element decay
Alpha decay:- it’s releases +2e charge particle from it
Beta decay:- it’s releases one neutron from it
Gamma decay:-it doesn’t remove the particle, only radiation released by it.

Complete step by step answer:
Radioactive elements which decay themselves and remove the lots of energy that we can be utilised for different purposes. One used to make electricity.
Radioactive element decay
- Alpha decay:- its releases +2e charge particle from it
- Beta decay:- its releases one neutron from it
- Gamma decay:- it doesn’t remove the particle, only radiation released by it.

Basic principle of a nuclear power plant is based on the law of conservation of energy. It converts thermal energy into electrical energy.
Nuclear thermal energy can be get by two method
By fusion of radioactive elements.(uncontrolled)
By fission of radioactive elements.(controlled)
Radioactive elements which decay themselves and remove the lots of energy that we can be utilised for different purposes. One used to make electricity.
Nuclear power plant works in a similar way as a thermal power plant. The difference between only is the fuel they used to heat the water in the boiler but in nuclear plants we used nuclear energy which can be obtained by the fission and fusion of radioactive elements.
Nuclear power plants used only fission because it can be controlled.
Nuclear Fission chain reaction :-
${}_0^1n + {}_{92}^{235}U \to {}_{56}^{144}Ba + {}_{36}^{94}Kr + 3{}_0^1n$

Due to this chain reaction, lots of thermal energy is generated. This energy is used to boil the water. Steam is applied on the turbine. This turbine converts mechanical energy into electrical energy. It is able to give 10MeV energy.
Hence nuclear reactors are used as power reactors to convert nuclear energy into electrical energy.

So, the correct answer is “Option D”.

Note:
The best way to solve problems is to analyze the basic working of a nuclear reactor as well as you should have to know about the number of reactor work on that process. You also have knowledge about nuclear fission and fusion.
