What are the advantages of nuclear energy?

The advantages of nuclear energy are as follows :

(i)a large amount of useful energy can be produced from a very small amount of a nuclear fuel .

(ii)a nuclear power plant is more efficient than other power plants because once the nuclear fuel like uranium-235 is loaded into the reactor, the nuclear power plant can go on producing electricity for two to three years at a stretch. There is no need for putting in nuclear fuel again and again.

(iii)It does not produce harmful gases like carbon dioxide which contributes to greenhouse effect or sulphur dioxide which causes acid rain.
