Supplying energy by nuclear power is a new trend in the recent years.Howeverit may be very dangerous.

Firstthe radioactive material must travel from its place of production to the power station.Although the power stations themselves are strongly builtthe containers used for the transport of the materials are not.Normallyonly two methods of transport are in usenamelyroad and rail.Unfortunatelyboth of these may have an effect on the general publicsince they are sure to pass nearor even throughheavily populated areas.

Secondthere is a problem of waste.All nuclear power stations produce wastes that in most cases will remain radioactive for thousands of years.It is impossible to make these wastes nonradioactiveso they must be stored in one of the inconvenient ways that scientists have invented.For examplethey may be buried under the groundor dropped into deserted minesor sunk in the area.Howeverthese methods do not solve the problemsince an earthquake could easily break the containers.

Thirdthere may occur the danger of a leak or an explosion at the power station.As with the other two dangersthis is not very likelyso it doesn't provide a serious objection to nuclear program.Howeverit can happen.

Separatelythese three types of dangers are not a great cause for worry.Taken togetherthoughthe probability of disaster is extremely high.
