The energy in the reactor of a nuclear power station is produced by the process of:

1. nuclear diffusion
2. nuclear fission
3. nuclear fusion
4. nuclear fermentation

 (b) nuclear fission

Explanation

The energy in the reactor of a nuclear power station is produced by the process of nuclear fission.

When the heavy nucleus of Uranium-235 atoms are bombarded with slow-moving neutrons, the heavy uranium nucleus breaks up to produce two medium-weighted atoms, barium-139 and krypton-94, with the emission of three neutrons. A tremendous amount of energy is produced in this process.

Reaction:

$_{92}^{235} \mathrm{U}+_{0}^{1} \mathbf{n} \stackrel{\text { fission }}{\longrightarrow}\ _{56}^{139} \mathrm{Ba}+_{36}^{94} \mathrm{Kr}+3_{0}^{1} \mathrm{n}+ Tremendous\ amount\ of\ energy\ (210MeV)$

${}_{92}^{235}\mathrm{U}{+}_0^1\mathbf{n}\stackrel{\text{ fission }}{⟶}{}_{56}^{139}\mathrm{B}\mathrm{a}{+}_{36}^{94}\mathrm{K}\mathrm{r}+3_0^1\mathrm{n}+Tremendousamountofenergy(210MeV)$
