The pressure vessel contains the reactor core with its fuel, coolant, moderator, control elements, and emergency systems. The turbine is the device that on receiving the steam it spins and turns the electric generators to produce electricity.
A fusion reactor is a type of nuclear reactor, one which fuses hydrogen atoms into helium atoms, as opposed to a fission reactor (by far the dominant source, and the only one used to commericaly generate power), which spilts uranium or plutonium atoms (mostly these two). Both use these reactions to generate heat, turning water to steam which then drives and turbine, which in turn drives a generator, creating electricity.
The heat energy resulting from nuclear fission is used to produce steam that spins the turbine.
If the reactor is in steady operation, not refuelling, or shutting down/starting up, I would think about 5 on the reactor itself, there will be others in the turbine hall and other equipment. There will be the reactor desk operator, his supervisor in overall charge, one or two plant attendants, and probably a maintenance engineer doing routine checks. This would be per shift, and there would be 4 or 5 shift teams to cover 24/7.
For the PWR, the reactor core which is an array of fuel assemblies, inside a very strong pressure vessel made of thick steel. The top of the vessel is removable for fuelling, and also holds the control rods and their mechanisms. The whole thing is enclosed in a secondary containment. Also inside this is the primary circuit which circulates water through the core to carry away the heat produced by the fuel assemblies, and the secondary circuit steam raising units which send steam to the turbine. See link below
it comes from nuclear fissionNuclear energy is the fission of certain, materials such as uranium or plutonium,within a nuclear reactor. This produces heat, which turns water into steam. This steam rises, driving a turbine which creates electricity for commercial and public use.
The energy released in a nuclear reactor is in the form of heat. This heat is used to boil water and produce high pressure steam which then drives the turbine.
turbine
You rip apart an atom which releases great energy in the form of heat. The energy causes water to evaporate which turns a turbine. The turning turbine creates electricity. This is how a nuclear reactor works.
Steam
Yes, that is how the nuclear energy is transferred to the turbine/generator
The nuclear reactor heats water into steam which is used to drive a turbine which turns a generator.
A steam turbine/generating unit, or a naval vessel
The nuclear reactor heats water into steam which is used to drive a turbine which turns a generator.
It can't as nobody has figured out how to make a fusion reactor.
reactor, steam turbine, and a (hopefully working) cooling system.
In a PWR the pressure in the reactor primary circuit is kept high enough to prevent boiling, and heat is transferred to a secondary circuit at a lower pressure where steam is produced for the turbine. In a BWR a proportion of the water passing into the reactor is allowed to boil off feeding directly to the turbine. Otherwise, the reactor core itself is very similar.
Basically, nuclear power plants use the heat from a nuclear fission reaction to boil water The steaming water then turns a turbine that generates electricity.
