Nuclear energy is, for the most part, generated by nuclear reactors. These reactors create hideously radioactive material when they burn fuel, and the spent fuel bundles remain radioactive for thousands of years. Storage and security are a problem. Accidents at nuclear plants are inevitable. Things break and people make mistakes, and we've seen that already. Oh, and we'll see it again. The clock is ticking. And it costs a mint to build the plants because of the safety issues (which cannot completely prevent accidents). Another "minor" problem is the one where a plant is used to make fissile material for a nuclear weapon. A number of countries are working along these lines as you read this. Problems dealing with spent fuel and those associated with accidents and the cost of constructing a plant cause people to hesitate to support nuclear power. And that's setting aside the proliferation of nuclear weapons.
It is expensive to build, and needs a lot of technical support, so it is not suitable for small utilities that don't have the resources to manage it. Also there are always public objections and difficulties with planning organisations, so it is easier to go with natural gas plants whenever this is possible.
The main reason why people are hesitant to use nuclear energy is because they are worried about safety. Since the 1986 Chernobyl incident there have been another 22 major nuclear power accidents.
people don't want to die
The USA uses the most nuclear energy. There is the highest number of Nuclear Power Plants in the world. The reason is simple: USA needs energy and the easiest way to get it is building nuclear power plants.
The term "nuclear energy prohibitive" means nuclear energy cannot be used. The exact reason depends on circumstances, but, in most cases, the problem is that nuclear power plant's output is constant, so, for example, if a nuclear plant powers a city, you need to divert excess power at night, when that city's consumption goes down. Hence, municipal electricity is nuclear energy prohibitive.
I see no reason not to. At least keep the present 20 percent, by building new plants to replace old ones as required
The reason nuclear energy is most efficient today is, because with little it can create a hundred times more. For instance, Japan's entire economy is constructed on nuclear energy. Even if they have suffered, because of some inconveniences, before that they use to be the leading economical giant. In general nuclear energy is the most efficient resource on the planet, right now.
There is No good reason, why you wouldn't use wind energy. Look at the oil spill in the Gulf of Mexico, look at the mine disaster in West Virginia. Look at the wastes from nuclear power. Wind power is the best energy source known to people.
One good reason-it has not been made to work yet! We do of course use solar energy which is produced by nuclear fusion

The same reason as the other countries that have nuclear power plans. Firstly to show off power. The other reason : Fear. Not even for energy generation, nuclear capability is justified due to the high risk that nuclear power plants represent.
I don't see any reason to think nuclear energy could be used more efficiently there than elsewhere
Japan and the US both use large amounts of nuclear power. The reason for this is both are highly populated, industrial countries. They use a lot of power, so they need efficient energy sources like nuclear power.
I don't understand what you mean. The US alone has over 100 nuclear reactors with more now on order

It has not been successfully developed yet on Earth, but it is the source of the sun's energy, so we all use it every day!
nuclear energy is produced by taking advantage of natural decay in large nuclei of atoms. atoms with large enough nuclei can only be produced by very large scale nuclear fusion such as stars during a supernova, and making it on earth would take enormous amounts of energy. So no, nuclear energy is not totally sustainable, but a small amount of fuel lasts a long time. For this reason energy can be stored by scientifically making large nuclei atoms and utilizing them later.
