The area of technology associated with nuclear energy is nuclear technology. Forms of nuclear technology include nuclear reactors and nuclear weapons.
Electromagnetism might be associated with a computer.
Nuclear power plants convert nuclear energy to electrical.sometimes it can be used to enrich radioactive nuclei which can later used in missile warheads. But using thorium as a source of nuclear power we can't enrich nuclei but we can use for electrical power generation which might have more energy than former
Nuclear energy is the energy within an atomic nucleus, and which holds the subatomic particles together ("binding energy"). It can also informally refer to electricity generation obtained from this energy normally by fission of radioactive elements.
It seems so, for example the US and many other countries have tried to stop Iran getting nuclear energy but it has still succeeded in obtaining it. In this case Russia has helped by providing fuel for the Bushehr plant, and says it will take back the spent fuel, so maybe there is no harm in this peaceful use. However Iran is also enriching uranium which might be used for weapons. Uranium is pretty widespread and so obtainable by fair means or foul, but a country still needs a specialised nuclear industry to succeed, unless another country supplies everything required. It's difficult to see a country such as the less developed African ones doing it, though South Africa did even under the apartheid regime, which was heavily sanctioned. North Korea and Pakistan are two others which have succeeded despite the efforts of the US to stop them.
The most prominent, positive way nuclear energy is used to produce, well, electricity. Unless you're speaking of a different kind of "nuclear energy", it is in fact primarily used to produce electricity for millions of people across the globe. Not all as scary as you might think it is.
