In a pressurized water-reactor, the primary cooling water circulates through the reactor core to remove heat generated by the nuclear fission process. This heated water then transfers its heat to a secondary water loop through a heat exchanger, where the secondary water is converted to steam to drive a turbine and generate electricity. The primary cooling water is then cooled down in a separate heat exchanger before being recirculated back into the reactor core.
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.
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.
One type of nuclear reactor is the pressurized water reactor (PWR). In a PWR, the heat generated by nuclear fission in the reactor core is transferred to water, which circulates through the core to create steam that drives turbines to produce electricity.
PWR stands for Pressurized Water Reactor, which uses pressurized water to transfer heat from the reactor core to the steam generators to produce electricity. BWR stands for Boiling Water Reactor, which directly produces steam in the reactor core to drive the turbines and generate electricity. Both are types of nuclear reactors used for power generation.
Boils in the core and is used to turn the turbine
In a pressurized water-reactor, the primary cooling water circulates through the reactor core to remove heat generated by the nuclear fission process. This heated water then transfers its heat to a secondary water loop through a heat exchanger, where the secondary water is converted to steam to drive a turbine and generate electricity. The primary cooling water is then cooled down in a separate heat exchanger before being recirculated back into the reactor core.
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.
It varies depending on the cooling needs and plant design.

the boiling water reactor, pressurized water reactor, and the LMFB reactor
The coolant used in a pressurized water reactor is typically purified water. This water is pressurized to prevent it from boiling and is circulated through the reactor core to remove heat generated during the nuclear reaction.
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.
One type of nuclear reactor is the pressurized water reactor (PWR). In a PWR, the heat generated by nuclear fission in the reactor core is transferred to water, which circulates through the core to create steam that drives turbines to produce electricity.
There are two primary design styles of fission reactors to produce electricity. Pressurized, and Boiling water reactors.
PWR stands for Pressurized Water Reactor, which uses pressurized water to transfer heat from the reactor core to the steam generators to produce electricity. BWR stands for Boiling Water Reactor, which directly produces steam in the reactor core to drive the turbines and generate electricity. Both are types of nuclear reactors used for power generation.
The pressurized water reactor (PWR) is a type of nuclear reactor where water is used as both a coolant and moderator. The reactor core heats up the water, which remains under high pressure to prevent it from boiling. This hot water then passes through a steam generator, where it transfers its heat to a separate secondary water system, creating steam to drive a turbine and generate electricity. The neat sketch of a PWR typically shows the core surrounded by the primary coolant loop and the secondary steam loop connected to the turbine generator.
