Control System for a Nuclear Reactor

The term Nuclear Reactor means of communication between two or more nuclei, nuclear particles, radiation, or possibly causing transformation of the nuclear type include, for example, fission, capture, and elastic container. The reactor is the core and its immediate container. Nuclear reactors used for electricity production. Non-nuclear reactors have increased sufficiently. Electricity is generated in a number of ways this can be obtained by using thermal energy. It can be used with the two main systems of the steam supply system and electricity generating systems of these two systems relate to each other. Steam Supply System produces steam from boiling water in the combustion of coal and electricity generating system produces electricity with steam turbines turning. Nuclear power plants this century depends on the particular type of nuclear reaction, fission (splitting heavy nuclei such as uranium atoms form two lungs of the division (Meshik, 2005).

Fragments, as well as less massive particles like neutrons). In a nuclear reactor it cleavage induced by the interaction of neutrons with fissile nuclei. In appropriate circumstances, "chain" of the fission reaction, in which events can be sustained. The energy released from fission to provide the heat some of which eventually turns into electricity. At present nuclear power plants per day, this heat is removed from the nuclear fuel on the water that is pumped past the rods that contain fuel. The main feature of a nuclear reactor is to release large amounts of energy from each division event which occurs in a nuclear reactor core. On average, fission releases about 200 million electron volts of energy. Typical chemical reactions, on the other hand releases about one electron-volt. The difference, about 100 million electron-volts. Full of division one pounds of uranium would release about as much energy as a combination of 6,000 barrels of oil and 1000 tons of high quality oil.

The reactor coolant serves a dual purpose. Its most relevant feature is removed from the main heat that results when the energy released from nuclear reactions into a collision in a random nuclear movement. Associated function is to transfer heat in this outside the nucleus, usually to produce electricity. Designer provides the nuclear core into the container through which cooling fluid is pumped. This fluid can be used directly to drive the turbine generator. Alternately, it can be used to heat a secondary fluid, which drives turbines. In the majority of all commercial systems, the liquid evaporates water.

This division is a term used to describe the splitting of heavy nuclei into two or more smaller nuclei. Slow neutrons are more easily captured by the kernel. Moderator environment causes neutrons to travel more slowly. Graphite, heavy water, beryllium, and all the excellent moderators, capable of slowing down neutrons without absorbing them. Neutrons released fission travel very quickly, if the moderator. Very large amount of energy released when an atom undergoes fission (Kragh, 1999).

In a typical fission reaction, the energy released is as follows: 170 MeV (megavolt) ...
