Its actually a bit more complicated than this single closed loop, because the water heated by the nuclear reactor itself becomes slightly radioactive. Because of this radioactivity, for safety reasons a system with two closed loops connected by a heat exchanger is used. In the primary loop the water just keeps circulating between the nuclear reactor and the heat exchanger. In the secondary loop the water circulates as in the steps listed above, but substitute Heat exchanger for Nuclear reactor.
To reduce radioactive contamination.
Most often, light water (H2O) is used as a moderator in a nuclear reactor. Sometimes, heavy water (D2O), or graphite is used.
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.
Heavy water(PHWR)--Pressurised heavy water reactor
Steam
The heat from nuclear fission is what generates electricity. Water is heated in a nuclear reactor, which then generates steam which is used to power electrical generators.
the boiling water reactor, pressurized water reactor, and the LMFB reactor
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.
Heat produced I'm a nuclear reactor turns water into steam that moves a massive turbine that my moving, produces energy. Water is then cooled and heated again to produce steam. Process keeps respecting itself.

The pressurised water reactor (PWR)
A nuclear reactor has basically one useful product that we can apply, and that's heat. We generally pump the primary coolant, which is heated by nuclear fission, through a steam generator. There, the heat of the primary coolant is picked up by the secondary water, and that water is turned into steam. The steam is then used to drive conventional steam turbines.
It is an almost insanely simple process. Water is heated by the nuclear reactor to the point it boils and this steam is used to drive a turbine which is connected to a generator. This generator creates the electricity we use.
