There are three parate sources of danger in supplying energy by nuclear power (原子能).
First, the radioactive material must travel from its place of production to thc power station. Ahhough the power statkms themlves are strongly built, the containers ud for the transport of the materials are not. Normally, only two methods of transport are itl u, namely road or rail. Unfortunately, both of the may have an effect on the general public, since they are sure to pass near, or even through, heavily populated areas.
Second, there is the problem of waste. All nuclear power stations produce wastes that in most eas will remain radioactive for thousands of years. It is impossible 女子人体艺术to make the wastes nonradioaclive, and so they must be stored iii one of the inconvenient ways that scientists have invented. For example, they may be hurled under the ground, or dropped into derted mines, or sunk in the a. However, the methods do not solve lhe problem, since an earthquake could easily break the containers.
Third. there may occur the danger of a leak (泄漏) or an explosion at the power station. As with the other two dangers, this is nm very likely, so it does not provide a rious objection to the nuclear program. Itowever, it can happen.
