Where does the water used to make steam in a power plant come from?
It is initially just normal mains water, but then it is purified by a demineralisation plant, so that water turning to steam does not leave deposits in the steam raising units or in the reactor in the case of a BWR. The steam is condensed to water after going through the turbine, and then recirculates, so the water makeup only has to replace loses due to leakage.
When using magma and water to create energy the magma's heat turns water into?
Steam is produced. The steam pressure can be used to drive turbine or piston driven electrical generators.
How do scientists change geothermal energy into electricity?
Scientists use geothermal power plants to harness the Earth's heat for electricity generation. These plants use the heat from underground reservoirs of hot water or steam to drive turbines, which then produce electricity. The steam or hot water is used to spin the turbines connected to generators that convert mechanical energy into electrical energy.
What is heat used from inside earth to produce steam?
Geothermal heat from inside the Earth is used to heat water and produce steam. This steam is then used to drive turbines connected to generators, producing electricity. Geothermal power plants harness this natural heat to generate renewable energy.
How is geothermal energy harnessed for energy?
There are two ways of using geothermal energy.1: There is domestic geothermal, where it is used locally to apply heat to your house or water heater.This is done by pumping water underground through pipes. The deeper underground the water is, the warmer the water will get by the use of the magma heating the earth underground. This can only be done in some locations, and is mainly used locally. So it does not make electricity, just uses the heat from underground.2: There are the big geothermal corporations, where they send water through pipes deep underground, where the water is heated by the magma. This causes the water to change phase, and become steam. The steam is then pressurized, and then put through turbines to make electricity.
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.
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.
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.
Are there more are there one type of nuclear reactor?
the boiling water reactor, pressurized water reactor, and the LMFB reactor
What is the pressurized water reactor describe it with neat sketch?
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 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.
Where to get steam from a submarine?
Only nuclear-powered boats generate steam for propulsion, electrical, and potable water conversion. The heat from the reactor flashes water into steam; the pressurized steam is then channeled toward a set of turbine generators, which provide electricity and are also connected to main engines for propulsion. Sea water is also desalinated using the the steam (condensed for various crew/boat uses) and stored as potable water for drinking/bathing, or de-ionized water for making oxygen.
How does nuclear reactor produce electricity?
A nuclear reactor produces electricity through a process called nuclear fission. The reactor uses uranium fuel to generate heat, which then boils water to produce steam. The steam drives turbines that are connected to generators, producing electricity.
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.
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.
