What does a steam generator do in a 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.

How does a steam generator work in a nuclear power plant?

The water in the core is heated by nuclear fission and then pumped into tubes inside a heat exchanger. Those tubes heat a separate water source to create steam. The steam then turns an electric generator to produce electricity. The core water cycles back to the reactor to be reheated and the process is repeated.

What does the generator do in a nuclear power plant?

Nuclear Power

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.

How does a steam generator work?

How Does It Work? Electric steam generators heat water to produce steam in a single vessel under forced pressure. A pump sends feedwater to the chamber containing submerged heating elements. Using this single pressurized chamber, incoming water is converted into steam when heated to boil under pressure.

Does a nuclear power plant use a generator?

Nuclear power plants are a type of power plant that use the process of nuclear fission in order to generate electricity. They do this by using nuclear reactors in combination with the Rankine cycle, where the heat generated by the reactor converts water into steam, which spins a turbine and a generator.

Is the steam from a nuclear power plant radioactive?

steam. This steam is not radioactive because it does not come into contact with the primary circuit. The cooling towers are part of the tertiary circuit and serve for the evacuation of heat resulting from the condensation, within the condenser, of steam coming out of the turbines.

What do you mean by steam generator?

Definition of steam generator

: a large apparatus for converting hot water into steam at high pressure and often with supplementary coils to superheat the steam.

Why did Chernobyl explode?

The Chernobyl accident in 1986 was the result of a flawed reactor design that was operated with inadequately trained personnel. The resulting steam explosion and fires released at least 5% of the radioactive reactor core into the environment, with the deposition of radioactive materials in many parts of Europe.

What is the role of a generator in producing electricity?

Generators don’t actually create electricity. Instead, they convert mechanical or chemical energy into electrical energy. They do this by capturing the power of motion and turning it into electrical energy by forcing electrons from the external source through an electrical circuit.

What do control rods do in a nuclear reactor?

A rod, plate, or tube containing a material such as hafnium, boron, etc., used to control the power of a nuclear reactor. By absorbing neutrons, a control rod prevents the neutrons from causing further fissions.

How do steam generators generate steam?

A steam generator is a device that uses a heat source to boil liquid water and convert it into its vapor phase, referred to as steam. The heat may be derived from the combustion of a fuel such as coal, petroleum fuel oil, natural gas, municipal waste or biomass, a nuclear fission reactor and other sources.

How can steam be used for power?

Steam power constitutes an important power source for industrial society. Water is heated to steam in power plants, and the pressurized steam drives turbines that produce electrical current. The thermal energy of steam is thus converted to mechanical energy, which in turn is converted into…

How does a steam generator produce electricity?

Making electricity from steam is generally a three step process, where water is converted to high pressure steam, then the high pressure steam is converted to mechanical rotation of a turbine shaft, and the rotating turbine shaft then drives an electric generator.
