How is electricity produced in a nuclear power plant quizlet?
how is electricity generated from nuclear power stations? heat generated in the reactor core, heat is removed by passing water through the reactor core . heated water is passed through the boiler which produces steam which turns the turbines which turn the generators thus producing electricity.
Is are the source of energy used in the production of electricity by nuclear power plants quizlet?
TestNew stuff! Electricity generation from nuclear fuel uses uranium-235 as a fuel source. A nuclear reaction in which a neutron strikes a relatively large atomic nucleus, which then splits into two or more parts, releasing additional neutrons and energy in the form of heat.
How are nuclear power plants different from other power plants?
Nuclear plants are different because they do not burn anything to create steam . Instead, they split uranium atoms in a process called fission. As a result, unlike other energy sources, nuclear power plants do not release carbon or pollutants like nitrogen and sulfur oxides into the air.
How does nuclear fission work in a power plant?
All nuclear power plants use nuclear fission, and most nuclear power plants use uranium atoms. During nuclear fission, a neutron collides with a uranium atom and splits it , releasing a large amount of energy in the form of heat and radiation. More neutrons are also released when a uranium atom splits.
In which part of nuclear power plant steam is produced Mcq?
In which part of nuclear power plant steam is produced? Explanation: There is no boiler in nuclear power plant. The heat energy released in the reactor during nuclear fission is utilised to heat the coolant. This coolant is circulated through the heat exchanger to produce steam.
Which method is used to produce electricity in the thermal power plant?
Traditional thermal power plants: also called combustion power plants, they operate with energy produced by a steam boiler fueled by coal, natural gas, heating oil, as well as by biomass. The steam activates a turbine which, in turn, drives an alternator to produce electricity.

Do nuclear power plants produce more energy?
Nuclear Has The Highest Capacity Factor
This basically means nuclear power plants are producing maximum power more than 93% of the time during the year . That’s about 1.5 to 2 times more as natural gas and coal units, and 2.5 to 3.5 times more reliable than wind and solar plants.
