The steam is used to spin large turbines that generate electricity. Nuclear power plants use heat produced during nuclear fission to heat water. … The heat produced during nuclear fission in the reactor core is used to boil water into steam, which turns the blades of a steam turbine.
What is steam turbine and how it works?
A Steam Turbine is a mechanical device that extracts thermal energy from pressurized steam and transforms it into mechanical work. … As hot, gaseous steam flows past the turbine’ spinning blades, steam expands and cools, giving off most of the energy it contains. This steam spins the blades continuously.
What is the purpose of a steam turbine?
A steam turbine is a device that extracts thermal energy from the steam and converts it to mechanical work on a rotating output shaft.
What is the function of the turbine in a nuclear reactor?
The Turbine has one major function: Convert the energy from the high pressure steam to mechanical energy in the form of shaft rotation so that the generator will turn.
Why is steam so powerful?
The water is still nearby, but it’s now in a gaseous form called steam. This form of water is also called water vapor, and it’s very powerful stuff. This is because steam has a lot of energy. … This is because as you continue to add more heat, more water molecules turn to vapor, and then you’re not heating them anymore!
Can steam turbine operates without lubrication?
Steam turbines cannot operate without lubrication. Therefore, turbine lubricating oil systems must be designed, operated and maintained for extreme reliability. Lubricating oil systems affect overall facility loss prevention more than most mechanical systems. They contain combustible liquid under pressure.
Why is steam turbine efficiency so low?
The compressor efficiency decrease is due primarily to the effects of compressor fouling. Any reduction in the turbine efficiency is due to the decrease in the turbine non-dimensional speed resulting from the increase in the turbine entry temperatures, as observed in Fig. 18.15.
