There is some sort of confusion here. There are two types of water moderated/cooled reactors: boiling water and pressurized water.
The boiling water reactor is at normal atmospheric pressure and the water in the reactor boils, producing steam directly.
The pressurized water reactor is at elevated pressure to prevent the water from boiling. A heat exchanger/steam generator is used to produce steam indirectly.
Other types of reactor (e.g. liquid metal, gas cooled, organic, aqueous homogeneous) also do not operate at pressures below atmospheric.
To keep the environment inside the power plant cool.
for pressurized light water reactor type, as an example, the nuclear reactor components are * Reactor vessel (that contains the nuclear fuel and surrounded with water and contains control rod for power control and for safety) * reactor coolant pump * steam generator * reactor pressurizer * piping out of the vessel to the pressurizer, from pressurizer to steam generator, from steam generator to reactor coolant pump, and from pump back to the reactor vessel.
Nuclear fission takes place in the nuclear fuel rods that are placed in the reactor core that is situated in the reactor pressure vessel. The reactor pressure vessel is usually situated inside the reactor containment.

An artificial nuclear reactor is a nuclear reactor that is created by man to utilize a nuclear reaction for energy, as opposed to natural nuclear reactors.
Nuclear reactor kinetics is the branch of reactor engineering and reactor physics and control that deals with long term time changes in reactor fuel and nuclear reactors.
yes, south Africa has a nuclear reactor.
how electricity is produced in a nuclear reactor
a nuclear reactor converts binding energy into heat. a nuclear power plant uses a nuclear reactor to generate electricity.
simply, the nuclear reactor is the source of heat (or steam) for the nuclear power plant.
This is used in the nuclear reactor that is known as Boiling Water Reactor (BWR) in which heat produced by the nuclear fission in the nuclear fuel allows the light water reactor coolant to boil. Then, the nuclear reactor moisture separator is used to increase the dryness of the produced steam before it goes to the reactor steam turbines.
