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 else can I help you with?
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.
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.
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 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.
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.
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.
How is a Pressurized Water Reactor different from a Boiling Water Reactor?

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.
What type of reactor uses fission to produce energy?
There are two primary design styles of fission reactors to produce electricity. Pressurized, and Boiling water reactors.
Why does Japan have many nuclear reactors?
The reason for having many reactors is because you can produce more electrical energy from them. Also Japan use BWR type reactors(Boiling Water Reactor) which are not as efficent as a more commonly used PWR reactor(Pressurized Water Reactor).
How big is the reactor vessel in a boiling water reactor?
A reactor vessel in a boiling water reactor is approximately 300 tons.
