If you mean a nuclear reactor, and not a chemical one, there is only one way, and that is by nuclear fission in the fuel
A pressurized water reactor typically has between two to four steam generators. These large heat exchangers are vital components in the reactor's secondary cooling system, where heat from the primary reactor coolant is transferred to produce steam for generating electricity in a turbine generator.
A hot spot in a tubular reactor refers to a localized region where the temperature is significantly higher compared to the rest of the reactor. This can lead to non-uniform reactant conversion and potential issues like thermal runaway. An example could be the buildup of coke deposits in a certain region of a tubular reactor, causing localized overheating and interfering with the reaction process.
That depends on the power rating of the reactor.
There are many things which give us heat such as the sun, fire and raidiators.light gives off heat
The quantity depends on: the type of the reactor, power of the reactor, enrichment of uraniu, chemical form of the fuel, etc. For a research reactor some kilograms, for a power reactor more than 100 tonnes/year.
The primary purpose of the cooling water in a reactor is obvious, cool the reactor core by carrying heat away to someplace else. That someplace else is usually a heat exchanger/steam generator, which generates steam to turn the turbine generators that make electricity. In light water moderated reactors, the cooling water also serves a secondary purpose as the moderator. The moderator is a material that slows the fast neutrons from the fission to slow thermal neutrons before too many are absorbed by the plentiful Uranium-238 isotope, which will not fission. These thermal neutrons then fission the rare Uranium-235 isotope to keep the reactor going.

The number of control rods in a nuclear reactor can vary depending on the design and size of the reactor. Typically, a nuclear reactor can have anywhere from 50 to 100 control rods. These rods are used to control the rate of the nuclear reaction by absorbing neutrons and regulating the power output of the reactor.
Nuclear fission reactors come in various forms, though the principle of using the heat from a nuclear chain reaction is always the same. 1. Pressurised Water Reactor (PWR). 2. Boiling Water Reactor (BWR). 3. Magnox gas cooled reactor (no longer built) 4. Advanced gas cooled reactor (no longer built but still in use in UK). 5. Canadian heavy water reactor (Candu) 6. Russian design of Chernobyl type. I think this covers the most used types for power generation. There are others such as the gas cooled pebble bed reactor, and the fast breeder reactor, that are possible but designs have not been so successful and these have not been adopted commercially.
10 Iraqi soldiers died, as well as a French adviser (the reactor was French built.
The electricity produced by a nuclear reactor can vary depending on its size and design, but a typical nuclear reactor can generate anywhere from 500 megawatts to 1,500 megawatts of electricity.
The reason for having many reactors is because you can produce more electrical energy from them. Also Japan use BWR type reactors(Boiling Water Reactor) which are not as efficent as a more commonly used PWR reactor(Pressurized Water Reactor).
