Not at all, the temperature of U-235 or Pu-239 which are used for nuclear energy production by fission, has no effect on the fission reaction, which is driven only by the capture cross-section for neutron capture. Slow neutrons are captured more strongly than fast ones, so it is an advantage for the moderator not to be at a high temperature.
Two dangers associated with nuclear fission are the risk of nuclear accidents, such as the Chernobyl or Fukushima disasters, which can release radiation into the environment and pose health risks to people nearby. Another danger is the potential for proliferation of nuclear weapons if nuclear materials are not properly secured.
The energy released by nuclear fission is primarily in the form of gamma rays, which are high-energy electromagnetic radiation. These gamma rays are emitted as a result of the conversion of mass into energy during the fission process.
There are two: Nuclear Fission and Nuclear Fusion. Fission is when a neutron is fired at an element with a high atomic number (usually Uranium) which then splits, releasing energy and more neutrons. this produces a chain reaction, which continues until all nuclei have been split. Fusion occurs in stars and a few experimental reactors, and happens when two forms of Hydrogen nuclei (Deuterium and Tritium) fuse into an unstable nucleus, which in turn splits again into Helium and a spare neutron. Fission can start at any temperature, but Fusion only when Hydrogen is in a plasma state.
Nuclear fission is a desirable energy source because it produces large amounts of energy without the emissions of greenhouse gases. It is a reliable and efficient source of power that can meet high energy demands. Additionally, nuclear fission does not rely on fossil fuels, reducing dependence on finite resources.
Some potential drawbacks of nuclear fission include the generation of radioactive waste that requires long-term storage, the risk of nuclear accidents such as meltdowns, the proliferation of nuclear weapons material, and the high cost of building and maintaining nuclear power plants.
Yes In high temperature gas cooled nuclear fission reactors using the nuclear process heat.
Nuclear fission - if large atomsNuclear fusion - if small atoms under high temperature and pressureNuclear decay - atoms of any size if unstableThe products of any of these processes usually have high kinetic energy, which is another way of saying they release heat.
Nuclear fusion requires extremely high temperature and great pressure.

Very high pressure at the centre due to gravity, and high temperature. Note however that temperature does not have to be so high as in tokamaks on earth, because the pressure and hence density of the plasma is so great.

nuclear fission results in the presence of used nuclear fuel that should be:either reprocessed (to gain back the remaining uranium and produced plutonium and to get the fission products as vitrified waste), orstored as high active waste; either under water or in dry storage casks.

Your question expresses a significant bit of conceptual confusion. Perhaps I can clear up some of this confusion and at the same time answer your question.What we call temperature is simply the manifestation of kinetic energy at the level of the atom (i.e. slow moving atoms = low temperature, fast moving atoms = high temperature). What we call nuclear energy is simply an excess in the nuclear binding energy, which is the energy binding the protons and neutrons together inside the nucleus and is a manifestation of the strong nuclear force and to a lesser extent the weak nuclear force. This movement of atoms has no affect at all on whether there is or is not excess nuclear energy inside atomic nuclei or if that excess nuclear energy is being released or even can be released. Those nuclei having the least nuclear binding energy are the nuclei of the elements from iron through lead, both the elements lighter than iron and the elements heavier than lead have more nuclear binding energy (which can be considered to be excess nuclear binding energy that could potentially be released).There are three processes that can release excess nuclear energy: radioactive decay, nuclear fission, and nuclear fusion. All of these processes transform nuclear energy to kinetic energy at the level of the atom (i.e. temperature aka heat), and thereby convert a small amount of the mass of the atom into energy. Of these three both radioactive decay and nuclear fission can take place at any temperature, even those so cold as to approach absolute zero. Neither radioactive decay nor nuclear fission takes place any faster or slower with a change in temperature. Nuclear fusion though can only take place at very high temperatures (and pressures) as the nuclei must be very close together and moving fast enough to be able to collide and fuse, despite the strong electrostatic repulsion due to both nuclei involved being positively charged. But this is a threshold temperature, even at high temperatures just below the threshold no nuclear fusion can take place at all and once above the threshold and nuclear fusion begins, raising the temperature further has very little affect on the rate at which that nuclear fusion takes place.Nuclear reactors operate using the process of nuclear fission and generate heat by both nuclear fission and radioactive decay. We are not yet able to extract nuclear energy in a controlled manner using the process of nuclear fusion (only explosive release of nuclear energy has ever been successfully done using the process of nuclear fusion).
Nuclear fission generates heat which is used to produce steam. The high-pressure steam spins a turbine by expanding through its blades. The turbine is connected to a generator, which converts the kinetic energy from the spinning turbine into electricity.
