All of the following are advantages of nuclear power EXCEPT: uranium mines cause less environmental damage than coal mines because less uranium is needed to generate power. nuclear power plants generate no nitrogen oxides and sulfur dioxide. uranium generates far greater amounts of energy than coal by weight or volume. the power-generating process is emission-free. nuclear wastes can be safely disposed of.

nuclear wastes can be safely disposed of

Explanation:

In comparing fossil fuel power plants with nuclear power plants, it is obvious that fossil fuel power plants lead to a large volume of emission of oxides of carbon and sulphur.

Also, a larger volume of coal needs to be burnt to generate energy compared to a minute amount of uranium fuel that can sustain a nuclear power plant for a long period of time thereby reducing the environmental damage associated with mining of the fuel.

However, the problem of nuclear waste disposal have remained a thorn in the flesh. It is often difficult to safely dispose of spent uranium fuel. This is a major disadvantage of the use of nuclear power.

the answer is 1 i believe

there are two significant figures.
