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.
What else can I help you with?
In a pressurized water reactor the primary cooling water is?
In a pressurized water reactor, the primary cooling water is kept under high pressure to prevent it from boiling at normal operating temperatures. This pressurized water flows through the reactor core to transfer heat from the nuclear fuel to a secondary system, where the heat is used to generate steam for electricity production.
What is PWR or BWR?
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.
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 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 are two types of reactors used in the US?
Pressurized Water Reactors (PWRs) and Boiling Water Reactors (BWRs) are two types of reactors commonly used in the US for generating nuclear power. PWRs use pressurized water to transfer heat, while BWRs use boiling water to produce steam for electricity generation.
Are there more are there one type of nuclear reactor?
the boiling water reactor, pressurized water reactor, and the LMFB reactor
What is the name of the coolant used in a pressurized water 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 pressurized water reactor the primary cooling water is?

This pressurized water flows through the reactor core to transfer heat from the nuclear fuel to a secondary system, where the heat is used to generate steam for electricity production.

In a pressurized water-reactor the primary cooling water?
Boils in the core and is used to turn the turbine

How many steam generators are there in a pressurized water reactor?
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.
Why do you keep the Ph of moderator neutral in pressurized heavy water reactor?
This is done in order to limit corrosion of the internal reactor components

Why 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.
Where will the next nuclear power plant be?
It will be on Lake Anna in North Anna Virginia. It will be of the economic simplified pressurized water reactor type. Owned by Dominion Resources. It will be on Lake Anna in North Anna Virginia. It will be of the economic simplified pressurized water reactor type. Owned by Dominion Resources.
