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.


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 a Nuclear reactor moisture separator?

This is used in the nuclear reactor that is known as Boiling Water Reactor (BWR) in which heat produced by the nuclear fission in the nuclear fuel allows the light water reactor coolant to boil. Then, the nuclear reactor moisture separator is used to increase the dryness of the produced steam before it goes to the reactor steam turbines.


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 is energy released in the reactor made to drive a turbine?

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.


What are two types of reactors used in the US?

There are amny different types of reactors but the most commonly used ones are: PWR-Pressurized Water Reactor, this works by pressurizing the reactor allowing the water to boil at a much higher temperature allowing efficentcy to be higher. BWR-Boiling Water Reactor,this is the most basic type of reactor this reactor just boils water that turns turbines and produces electricity, however water levels and temperature have to be constantly monitored, otherwise a reactor could slip into a dangerous state. AGR-Advanced Gas Reactor, this reactor instead of being cooled by water it is instead cooled by pressurized carbon dioxide. FBR-Fast Breeder Reactor, this reactor instead of limiting fast neutrons to occur it allows fast neutrons in the reactor and in the act of doing it produces nuclear fuel that can be used to fuel the reactor.


Are there more are there one type of nuclear reactor?

the boiling water reactor, pressurized water reactor, and the LMFB reactor


How big is the reactor vessel in a boiling water reactor?

A reactor vessel in a boiling water reactor is approximately 300 tons.


Boiling water reactor nuclear power plant?

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.


What is PWR or BWR?

PWR = pressurised water reactor. BWR = boiling water reactor


How does nuclear power work explained simply?

Radioactive decay generates heat. The heat is used in a reactor to boil water. The steam of the boiling water is used to drive a turbine which runs a generator to produce electricity.


State different names of thermal power plant?

Different types of nuclear plants: Pressurised Water Reactor (PWR); Boiling Water Reactor (BWR); Heavy Water Moderated Reactor (CANDU); Advanced Gascooled Reactor (AGR); Fast Breeder Reactor (FBR); Pebble Bed Gascooled Reactor; Water Cooled Graphite Reactor (RBMK). There are other ideas that only exist on paper.
