Uranium is the fuel... moderators can be water... control rods are various substances to absorb extra neutrons some use carbon. Steel (iron) is what the reactor vessel is made of.
Uranium, and plutonium. (And, to a lessor degree, thorium.)
Nuclear reactors use controlled nuclear fission reactions to generate heat, which is then used to produce steam that drives turbines to generate electricity. The heat is produced in the reactor core where nuclear fuel rods containing uranium or plutonium undergo fission reactions. The reactor's cooling system helps regulate the temperature and prevent overheating.
India primarily uses uranium and thorium as radioactive elements for its nuclear reactors. Uranium is the primary fuel for Pressurized Heavy Water Reactors (PHWRs), while thorium is used in some reactors as a fertile material for breeding fissile uranium-233.
We use nuclear fission in nuclear reactors to tap nuclear energy.

No, at least not for power reactors
No substitute for nuclear power reactors especially if there is no available fossil fuel.
The most common coolant used in nuclear reactors is water, in either liquid or steam form. Water provides effective heat transfer properties and is readily available and cost-effective. Other coolants, such as liquid sodium or gas, are used in specialized reactors but water-cooled reactors are the most prevalent.
Nuclear reactors and nuclear weapons
No, nuclear fission operates all nuclear reactors. If they are power plant reactors it is used to generate electricity.
Radioisotopes are used in nuclear reactors as fuel to generate heat through nuclear fission. The heat produced is used to generate steam, which drives turbines to generate electricity. Radioisotopes such as uranium-235 and plutonium-239 are commonly used in nuclear reactors.
