Nuclear power is the controlled use of nuclear energy. Nuclear energy is

energy in uranium that can be released by nuclear reaction in a machine is

called a nuclear reactor. This energy is made into electricity, which can be

used to power machine and heat home. 14% of the world’s electricity came from

nuclear power. But, the use of nuclear power causes some hazard.

There are

three separate sources of hazard in the process of supplying energy by nuclear

power. First, the radioactive material must travel from its place of

manufacture at the power station. Although the power stations themselves are

solidly built, the containers used for the transport of the materials are not.

There the normally only two methods of transport available, namely road or

rail. Unfortunately, both of these involve close contact with the general

public, since the routes are sure to pass near, or even thought, heavily

populated areas.

Next, there is the problem of waste. All nuclear power station produced

wastes that in most cases will remain radioactive for thousands of years. It is

impossible to make these wastes non-radioactive, and so they must be stored in

one of the inconvenient ways that scientist have invited. For example they may

be buried under ground, or dropped into abandoned mines, or sunk in the sea.

However, these methods do not solve the problem, since an earthquake could

easily crack the containers open.

Finally,

there is the problem of accidental exposure due to a leak or an explosion at

the power station. As with the other two hazards, this is not very likely, so

it does not provide a serious objection to the nuclear program. Nevertheless,

it can happen.
