Nuclear Power

Function of Reactor in Nuclear Power Generation:


A nuclear reactor produces and regulates the release of energy from the splitting of atoms of uranium.

Uranium Fuel nuclear power is a clean and efficient way of boiling water into steam. With the exception of the reactor itself, a nuclear power plant works like most coal or gas plants

Reactor Core:

Several hundreds of thousands of fuel elements with small ceramic pellets of uranium oxide fuel cell are the core of a reactor.

In the reactor core -235 isotope uranium fissions or cracks, which produces a lot of heat in a continuous process called a chain reaction. The method is dependent on the presence of a moderator such as water or graphite, and fully controlled.n

The moderator slows the neutrons produced by the fission of uranium nuclei, so they produce more fissions.

Some of the uranium-238 is converted in the reactor core in plutonium.

The fission products remain in the ceramic fuel and undergo radioactive decay, releasing a little more heat. These are the most important waste of the process.

The reactor core is within a steel pressure vessel. The water around it also remains liquid at operating temperatures above 320 ° C. Steam is generated to the top of the reactor core or in separate pressure vessels. Steam drives the turbine to produce electricity. steam is then condensed and recycled water.

Reactor Type:


The basic design consists of a pressurized water reactor. Reactor has its main water cooling / heat transfer circuit. Reactor generates steam in a secondary circuit. The more popular boiling water reactor produces steam to the main circuit above the reactor core, but it is still under great pressure. Using both types of water as both coolant and moderator

The autoclave steam generator which is housed in a massive container structure reinforced concrete about 1.2 meters thick. This is to protect the protect neighbors if there is a major problem within the reactor and the reactor against external attacks.

Radioactive decay generates heat even after the reactor is shut down. The cooling system provides to remove the heat and the basic heat output.

Natural Prehistoric Reactors:

The world’s first nuclear reactors operate with natural uranium deposit about two billion years ago in what is now Gabon. This rich uranium orebodies in the crust and moderated by seeping rainwater.

Nuclear Contribution:

Nuclear energy supplies about 11% of the electricity in the world. Today, 31 countries make use of nuclear energy to generate electricity. Many people rely on it for a quarter to a third of their offerings.
