Nuclear fission in U-235 and Pu-239 produces heat which is then used to raise steam and generate electricity. In fact the fission process is most efficient with slow neutrons rather than fast ones, which is why reactors have a moderator (light or heavy water or graphite).
Induced radioactivity by exposure to fast neutrons is a different matter, material in the reactor like the control rods or the pressure vessel itself do become radioactive because they are as you say bombarded with neutrons, but this radioactivity only produces a trivial amount of extra heat from the reactor.
In small reactors not built for power production samples of various substances can be irradiated to make radioactive isotopes for medical and industrial use. In this type of reactor the heat from the fission process is generally thrown away to atmosphere, it might typically be a few megawatts.

How is it possible to induce a nuclear reaction?
Not by chemical means. A nuclear reaction can be induced by bombarding the nucleus with neutrons, alpha particles, beta particles, gamma rays, high velocity nuclei from a particle accelerator, or cosmic ray particles. Neutrons are most effective at causing nuclear reactions as they have no charge and are reasonably massive.
Why do you choose isotopes with medium long half-lives as emitter in radiotheraphy?
Mainly for two reasons:to reduce as far as possible the radioactivity and hence reduce the radioactivity passive health effects; as the element radioactivity is inversely proportional to its the half live.To reduce as far possible the loss of the radioactive element through its radioactive decay during storage for non use.
Is a chain reaction possible in a substance that emit no neutrons when it fission?
ff
How Is it possible for the atoms of different elements to have the same mass numbers?
It is possible only because of different number of neutrons.
How do you find the atomic mass of an element if you don't know the number of neutrons?
It is not possible.
It is possible to cause artificial radioactivity by bombarding a nucleus with high velocity neutrons this process is called nuclear fission this reaction is the basiis of nuclear power stations as?
yes it is possible to do so........using Einstein's equation E=ΔmC2.....
Are protons made in the nucleus?
Protons are not made in the nucleus. It is possible for neutrons to become protons and protons to neutrons due to radioactivity, but still, this does not mean they are "made".
How do you know that an atom of gold in a ring and an atom of gold in dental fillings are alike?
Because all the atoms of a chemical element are identical (excepting the number of neutrons or the possible radioactivity).

Is it possible to make an artificial ozone layer?

How do you find the neutrons when you know the atominc number?
It is not possible.
Can there be an odd number of neutrons in an element?
Yes, it is possible.
Why is not possible to determine the type of atom by simply knowing how many neutrons it has?
because the neutrons have no charge
Is alchemy performable?
Physically, yes, but only if you're really willing to painstakingly bombard an atom of iron with enough protons, neutrons and electrons safely enough to make a gold atom without destroying something or releasing radioactivity in the process. So no, it's not really possible, at least not with current technology.
Is it possible to create a artificial atmosphere on Mars And if yes then how?
It is not currently possible to create an artificial atmosphere on Mars. Even if it was, Mars does not get enough sunlight needed to sustain human life.
Can light be used to manipulate atoms to create an object?
In theory yes, by "bombarding" atoms with the right photons, you can alter it's structure. However, it's not practically possible.
