The most common power reactor types use water with more than 90 of the world s reactors being water based. Nuclear reactors come in many different shapes and sizes some use water to cool their cores whilst others use gas or liquid metal. Two examples of nuclear fissioning of uranium 235 the most commonly used fuel in nuclear reactors.
This water is then returned to the reactor core completing the loop. The steam is directly used to drive a turbine after which it is cooled in a condenser and converted back to liquid water. A boiling water reactor bwr uses demineralized water as a coolant and neutron moderator heat is produced by nuclear fission in the reactor core and this causes the cooling water to boil producing steam.
There are several types of power reactors but only one the light. There are also numerous research reactors and some navies of the world have submarines or surface ships driven by propulsion reactors. Most of the world s existing reactors are power reactors providing the heat needed to turn turbines that run electric power generators.
Nuclear reactor nuclear reactor types of reactors. A reactor core is typically made up of a couple hundred assemblies depending on power level. Typically more than 200 of these rods are bundled together to form a fuel assembly.
The uranium is processed into small ceramic pellets and stacked together into sealed metal tubes called fuel rods. Reactors use uranium for nuclear fuel. World nuclear association federation of.
A reactor also has a moderator a substance that slows the neutrons and helps control the fission process most reactors in the united states use ordinary water but reactors in other countries sometimes use graphite or heavy water in which the hydrogen has been replaced with deuterium an isotope of hydrogen with one proton and one neutron source. Experiments the international thermonuclear experimental reactor will be based. It sounds futuristic and.
That s the difference nuclear fusion.
Nuclear reactor diagram. In order to turn nuclear fission into electrical energy nuclear power plant operators have to control the energy given off by the enriched uranium and allow it to heat water into steam. That steam then drives turbines to generate electricity source. Enriched uranium typically is formed into 1 inch long 2 5 centimeter long pellets each with approximately the same diameter as a dime. It is now used in most us reactors and a few in asia.
China has the technology for ap1000 reactors. The power rating of a nuclear power reactor. Nuclear plant reactor power outputs are quoted in three ways. Thermal mwt which depends on the design of the actual nuclear reactor itself and relates to the quantity and quality of the steam it.
A nuclear reactor formerly known as an atomic pile is a device used to initiate and control a self sustained nuclear chain reaction nuclear reactors are used at nuclear power plants for electricity generation and in nuclear marine propulsion heat from nuclear fission is passed to a working fluid water or gas which in turn runs through steam turbines. Click on the diagram to see a bigger view. Nuclear reactors are basically heat engines. As uranium fissions the breaking apart of atoms releases energy much of it in the form of heat which can then be used to do work.
In a nuclear powered submarine reactor heat produces steam to drive the turbines that provide the submarine s actual power. Nuclear reactors diagram.
