Nuclear power is an excellent non-conventional source of energy still it is not used commonly for power generation because:

(a) In the old nuclear reactors, there is a risk of accidents due to the leakage of radioactive material which can cause serious damage to the living beings and the environment.

(b) The nuclear waste produced in the nuclear power plants are radioactive and are very harmful to the living beings. If it is not disposed of properly, it may lead to contamination and a longer exposure can lead to cancer.

(c) The nuclear plants are very expensive to install and the limited availability of uranium fuel makes the large scale use of nuclear energy prohibitive.
