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.
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.
What is the steam point of the Celsius scale?
at 100 degrees liquid water will go to steam and steam will go to liquid water
Water in its gas state is called?
Water in it's gaseous form is referred to as steam. steam
Are white clouds seen above boiling water are steam true?
false <><><><> What you are seeing is water vapor. Steam- REAL steam- is transparent.
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 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.
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.

What are the necessary components for a nuclear reactor?
for pressurized light water reactor type, as an example, the nuclear reactor components are * Reactor vessel (that contains the nuclear fuel and surrounded with water and contains control rod for power control and for safety) * reactor coolant pump * steam generator * reactor pressurizer * piping out of the vessel to the pressurizer, from pressurizer to steam generator, from steam generator to reactor coolant pump, and from pump back to the reactor vessel.
Are there more are there one type of nuclear reactor?
the boiling water reactor, pressurized water reactor, and the LMFB reactor
How is water is used in nuclear power generation?
Water is used to transfer heat from the nuclear fuel in the reactor to the steam generators where it transfers heat to the secondary water to make steam. The steam is then used to turn turbines. Water from an external source is also used to condense the steam from the turbine exhaust, and this water is then returned to the steam generators to continue the cycle.
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 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.
In a pressurized water reactor the primary cooling water is?
In a pressurized water reactor the primary cooling water is under pressure of around 150 atm and its inlet temperature around 320 degree centigrade.
Why is the water that is used to cool the reactor vessel of a nuclear power plant is kept separate from the water that is heated to produce steam for the turbine generators?
To reduce radioactive contamination.
How is electricity made at a nuclear powerstation?
Electricity is made at a nuclear power station by creating a controlled nuclear chain reaction, fission, in the reactor core. This fission process generates heat, lots of it, due to the release of binding energy resulting from the loss of mass in the core. A coolant, usually water, keeps the temperature from reaching excessive levels. In the BWR (Boiling Water Reactor) that coolant flashes to steam. In the PWR (Pressurized Water Reactor) that coolant heats other coolant which flashes to steam. The steam spins a turbine / generator which makes electricity. The steam, which has now been condensed back to water by the turbine and condensor is reheated and fed back to the core (BWR) or steam generators (PWR) to repeat the cycle.
