It is the fission reaction where the free neutron impacting nucleus cause the nucleus splitting to another elements. Some of the mass loss would transformed to energy by the famous Energy - Mass relation E = mc2.

∙ 14y agoIn a PWR the primary circuit is kept at a very high pressure to prevent boiling so that the reactor outlet water temperature can be high enough to transfer heat to the lower pressure secondary circuit water producing steam in the steam raising units.
In a BWR boiling is allowed in the reactor core itself, so that at the reactor outlet there is a mixture of water and steam. The steam is then separated in a separator unit above the core, inside the pressure vessel, and passes directly to the steam turbine. This means that the turbine becomes slightly contaminated with activity, whereas in the PWR it is not in contact with reactor water.

There are other designs that use higher enrichment, as well as designs that use plutonium-239, uranium-238 when there is a source of fast neutrons such as in a breeder, or thorium-232 where there is a source of thermal neutrons.
Put simply, nuclear atoms are used to generate steam.

What is the difference between a pressurized water reactor and a boiling water reactor?
The primary difference between a pressurized water reactor (PWR) and a boiling water reactor (BWR) is that in the BWR, water is actually boiled, and the steam is used to drive a steam turbine, while in the PWR, the primary coolant is not allowed to boil, but is circulated in a closed loop to boil water in a steam generator. The BWR circulates primary coolant through the steam turbine in a closed loop. The PWR contains the primary coolant in a loop that includes the steam generator, and not the steam turbine.
What are the necessary components for a nuclear reactor?
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.
Why is it necessary to enclose the nuclear reactor at low pressure?
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.
How do you make water energy frome eletrical energy?
This is how a Pressurized Water Reactor works. The water is at a high pressure to prevent boiling, and it is then hot enough to produce steam in a secondary circuit, to feed a steam turbine. spelt something wrong lmao =]
How is a Pressurized Water Reactor different from a Boiling Water Reactor?
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.
How many steam generators are there in a pressurized water reactor?

What is a reaction steam turbine?
Steam turbine is when a device that has the extract thermal energy from pressurized steam. It is used to do mechanical work on a rotating output shaft. The steam turbine was invented by Sir Charles Parsons in 1884.

What is pwr and bwr?
I think you are talking about nuclear reactors. PWR is a Pressurized Water Reactor, and is the basis for most power generators. BWR is a Boiling Water Reactor. As the water is a major moderating component, controlling the speed and intensity of the nuclear reaction, the steam bubbles in a BWR can present a problem.
What is BWR of nuclear energy?
BWR = Boiling Water Reactor. In this type a certain proportion of the reactor coolant water is allowed to turn to steam (unlike in a PWR), this steam is separated out from the water after the reactor outlet and passes directly to the steam turbine.
How a nuclear power plant generates electricity?
A nuclear power plant generates electricity by turning turbines that turn generators. This is no different than fossil fueled plants. The difference in nuclear power is the source of the steam. Instead of a fossil fuel boiler, there is a nuclear reactor that uses the power of the release of binding energy (Strong Atomic Force) from the fissioning of (generally) Uranium-235. There are several designs. The two primary designs are the Boiling Water Reactor (BWR) and the Pressurized Water Reactor (PWR). The BWR forms steam in the reactor vessel which is transported to the turbines. The spent steam is condensed, reheated, treated, and returned to the reactor. The PWR forms heated water in the reactor vessel which generates steam in a separate steam generator (heat exchanger) which then is transported to the turbines. The rest of the cycle is similar to the BWR, but the return water goes to the steam generators instead of the reactor.
