Well their are no disadvantages to nuclear plants, if your using them for nuclear power, as nuclear power is the safest type of energy in modern times.

Nuclear weapons are weapons which are fueled by nuclear energy. Examples of weapons that can be fueled by nuclear energy are missile warheads and bombs.
