Nuclear Energy? Is it necessary?

In a tropical country X, one of the ministers suggested that the country should use nuclear energy to generate electricity, instead of burning fuels. According to him, nuclear energy does not bring harm to the environment and it isn't too expensive. He said he's planning to do this in his country.

Well, I was wondering if using nuclear energy to generate electricity is necessary in this country. As stated above, X is a tropical country. It locates at the Equator. Solar energy can be acquired almost every day, which can be the cheapest and the most abundant natural resources.

Nuclear energy, even though it can be use to generate large amount of electricity, it requires a lot of radioactive substances. After using those radioactive substances, the wastes need to be discarded. This action may pollute the environment. On the other hand, solar energy does not cause so much trouble as the nuclear energy does. It only requires photovoltaic cell, which can convert the solar energy into electrical energy.

Are those people helping the country? Or simply trying to come out with more projects to bring them more income? I wonder.
