Steam turbines for nuclear power plants employ an extremely long last stage blade (LSB), with the high pressure (HP) turbine, low pressure (LP) turbine and generator arranged along a single rotor, generating up to 1,800 MW.
What is a turbine in a nuclear power plant?
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. As the turbine blades turn, they drive generators that make electricity.
Which type of generator is used in nuclear power plant?
Steam generators are heat exchangers used to convert water into steam from heat produced in a nuclear reactor core. They are used in pressurized water reactors (PWR) between the primary and secondary coolant loops.
What types of power plants use turbines?
Wind power plants: Wind power plants convert wind energy to electrical energy using wind turbines. These are also very effective at producing clean energy.
Does nuclear use a turbine?
Nuclear energy originates from the splitting of uranium atoms – a process called fission. This generates heat to produce steam, which is used by a turbine generator to generate electricity. Because nuclear power plants do not burn fuel, they do not produce greenhouse gas emissions.
Why is nuclear energy bad?
Nuclear energy produces radioactive waste
A major environmental concern related to nuclear power is the creation of radioactive wastes such as uranium mill tailings, spent (used) reactor fuel, and other radioactive wastes. These materials can remain radioactive and dangerous to human health for thousands of years.
What are two types of nuclear power plants?
U.S. nuclear power plants use two types of nuclear reactors
Nuclear power plants in the United States have either a boiling-water reactor or a pressurized-water reactor.
How efficient is nuclear?
Nuclear is reliable.
Nuclear plants are the most efficient source of electricity, operating 24/7 at a 93 percent average capacity factor. … That’s more than two times the capacity factor of any other carbon-free source.
What are the 6 methods of producing electricity?
In this learning activity you’ll review the six different ways in which electricity is produced: chemical, friction, heat, light, magnetism, and pressure.
