The present use of uranium 235 will probably be able to continue another 50 years or so, depending on how many reactors are built worldwide. There are other possibilities including breeding fissile fuel from uranium 238 or thorium. Then fusion may also become feasible, and there is plenty of fuel for that available.
The process in which the nuclei of two atoms combine to form a larger nucleus is called nuclear fusion. This process releases a large amount of energy, such as in the sun where hydrogen atoms fuse to form helium. Fusion is the opposite of nuclear fission, which is the splitting of a larger nucleus into two smaller nuclei.
Nuclear power is very good source of energy to turn to. The only problem is the storage of nuclear waste, that is left over after the nuclear reaction the power plant. The energy obtained from the nuclear power plant is very clean burning and more KJ/mole energy.
I wouldn't say that electrical energy "uses" other types of energy; probably you mean that you can convert other types of energy to electrical energy. Most types of energy can be converted to electrical energy, or actually all of them (as long as there is some useful energy left) - including heat energy, nuclear energy, chemical energy, mechanical energy, etc.
The ultimate result is the pollution of the environment. Any nuclear accidents leave the area unusable for centuries. When the nuclear reactor melted down in Russia in the 80's it left the entire area radioactive. People can no longer live there and any plants and animals are affected by the radiation that still exists.
To answer your question we first have to dive into what 'heat' is. Heat is "the average random molecular kinetic energy of an object". All that really means is heat is caused by the movement of molecules in an object. The 'faster' they are moving, the more heat there is.In the nuclear fission process, heat is produced when a fissionable material (like Uranium) is split apart. This results in numerous byproducts. Including, fission fragments (the 2 or 3 elements left over from the split uranium atom. Normally these are Krypton and Barium), gamma radiation, beta radiation (beta radiation is just high energy electrons), fast neutrons, and neutrinos (there are others, including things like alpha radiation from the decay of radioactive material but you get the point). All of these things have a large amount of energy from the fission process and they 'speed off' through the core. As they 'fly around' they transfer energy to their neighboring particles. This is especially true for the fission fragments who have a relatively large mass and a high charge. This transfer of energy is what causes the 'heat'. The nearby particles are being 'pushed' around and therefore their 'average random kinetic energy' goes up.Hope this helps.
It is the only sustainable energy that we have. There are only two valid sources of any energy, fossil fuels and nuclear. With less then a 1000 years of oil left, we know fossil fuels will end. Nuclear is also much cleaner. Those that do not understand climate and CO2 also worry about CO2 emissions. The only fuel that produces zero CO2 is nuclear.Most countries have determined that nuclear is a valid source of power. France brags about how green they are. This is because they are over 90% nuclear.
In nuclear fission it is the nucleus of the atom that splits, not a molecule, and this releases neutrons and energy. Reactions at the molecule level are termed chemical reactions, not nuclear, and these chemical reactions involve whole atoms and molecules.
Energy is neither created nor destroyed. It is simply converted from one form to another. In nuclear fission (the splitting of atoms) the nucleus is split into two or more parts. The binding energy that represented the parent nucleus is now split into three or more parts - the binding energy that represents the two new nucleuses - and the residual binding energy that is left over. The residual energy is often represented as heat and radiation.

net production is the amount of energy left that is in the next trophic level
As you move across a period in the periodic table from left to right, ionization energy generally increases. This is due to the increasing nuclear charge, which attracts electrons more strongly, making them harder to remove. Conversely, as you move down a group, ionization energy decreases because the outer electrons are farther from the nucleus and are shielded by inner electrons, reducing the effective nuclear charge felt by those outer electrons.
The first evidence of nuclear energy was found in the late 1800s when a scientist found that sealed photographic plates that he had left in his desk drawer with some rocks were fogged when developed. This effect (of the rocks on the plates) was called radioactivity. It took many experiments to find ways to get this energy on demand.
Poodles can't be left on their own, because they have a large amount of energy, which means they need a lot of exercise.
Mostly the long lived radioactivity left in the spent fuel, but also any leakage from a damaged plant as at Fukushima.

Nuclear fusion involves the joining together of two atomic nuclei, fusing them into a single nucleus. When you join two nuclei together (usually light nuclei with only a few protons and/or neutrons), a tremendous amount of energy is released. Just as it takes a tremendous amount of energy to pull apart the pieces of a nucleus, when you put two pieces together, a lot of energy is released. Fusion is often confused with nuclear fission, but they are very different. Fission involves the breaking apart of a single nucleus into two smaller nuclei. Fusion is joining nuclei. Fission is breaking apart a nucleus. A tremendous amount of energy is released upon joining two nuclei together (it is this reaction that is happening inside the sun). It also takes a huge amount of energy to get this reaction to occur. The only way we currently know how to start a nuclear fusion reaction efficiently is to use an atomic bomb to get it started! This is how much energy you need to start the reaction! There are several other ways that we know of to start fusion reactions, but they all require more energy input than you get as energy output. There is a tremendous amount of research currently on so-called "cold fusion" or a way to do fusion without this huge amount of energy input. Currently all known methods involve putting in MORE energy than you get out! That's not a good design for a power plant, to say the least (nor is having atomic bombs going off inside to keep the reactors going!).
