Many times these types power plants have had very dangerous disasters.
Nuclear energy has one of the lowest impacts on the environment of any energy source because it does not emit air pollution, isolates its waste from the environment and requires a relatively small amount of land. Nuclear energy stations do not produce air pollutants or greenhouse gases when they generate electricity, but if something were to go wrong the whole town would have to be abandoned.
For 50 years, nuclear power stations have produced three products which only a lunatic could want: bomb-explosive plutonium, lethal radioactive waste and electricity so dear it has to be heavily subsidised. They leave to future generations the task, and most of the cost, of making safe sites that have been polluted half-way to eternity.-James Buchan
