15. Nuclear Power
There are three separate sources of hazard in the process of supplying energy by nuclear power.
The radioactive material must travel from its place of manufacture to the power station. Although the power station themselves are solidly built, the container used for the transport of the materials are not. There are normally only two methods of transport available, namely road or rail. Unfortunately, both of these involve close contact with the public, since the routes are sure to pass near, or even through, heavily populated areas.
Next, there is the problem of waste. All nuclear power station produce wastes that in most cases will remain radioactive for thousands of years. It is impossible to make these waste nonradioactive, and so they must be stored in one of the inconvenient ways that scientists have invented. For example, they may be buried under the 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.
