Q.

Give differences between nuclear fission and nuclear fusion.

Q. S1 : In an ordinary power station we burn fuel to get heat.
S6 : However, instead of getting heat by burning fuel, we get it from the nuclear reactor.
P : In a nuclear power station, we burn water into steam and then use the steam in the same way.
Q : It is from the generator that we get electricity.
R : The steam is then made to turn turbine and through the turbine generator.
