Nuclear and Thermal Power Plants

Introduction

A nuclear plant has many more reactors and the term is often used inaccurately as nuclear reactor. For example, with the statement in USA, it ran up to the nuclear phase-out 17 nuclear power plants that mean 17 nuclear reactors are running at fewer locations. Most nuclear reactors are at fixed installations. In addition, there are nuclear reactors in submarines and other vessels. For example the U.S. has some nuclear powered aircraft carrier, and France has six nuclear powers, nuclear-powered submarines and nuclear-powered hunting submarines (Mariazzi, et al, 1992, pp. 129-140). In 2011, there were ten nuclear icebreakers and four nuclear-powered cargo ship, vehicles, aircraft or ships. In atomic euphoria of the late 1950s and early 1960s, the idea came up of nuclear-powered road nuclear fuel and the use of nuclear power has emerged as a possible solution towards the problem of the greenhouse effect (not greenhouse gases that are emitted into the atmosphere, contributing to the diversification of energy sources, reducing the country's vulnerability to fluctuations in the price of fossil fuels), but the risks inherent in the production of electricity in using this source (danger of nuclear explosion and radioactive leakage, production of radioactive waste, radioactive contamination, thermal pollution without forgetting also the high cost of construction and maintenance of facilities, contribute significantly to the use of this energy source continues to be regarded by many as a risk inadvisable (Mariazzi, et al, 1992, pp. 129-140).

Comparison between Nuclear Power Plant and Thermal Power Plant

Major Difference

Thermal power plant uses the thermal energy which is important in preserving the environment, it has many advantages over other ways of obtaining energy, such as not polluting, rational, not need turbines or generators to produce electricity, requires no maintenance and no consumption, no fuel, but it has the disadvantage of requiring large investments for your use (Schubel, Coutant & Woodhead, 1978, pp. 19-93). It derives the energy of sunlight can be converted via photovoltaic or to produce electricity by thermally to produce heat and electricity.

Nuclear power plant is considered as the subject of industry and energy which is thermal power plant that produces electricity by using energy derived from nuclear fission of atoms, usually uranium (natural uranium or slightly enriched in the isotope U-235), in which the heat necessary to obtain the water vapor is obtained of a nuclear reactor.

In a nuclear reactor as a result of nuclear fission reactions produce large amounts of heat which is received by the working fluid (usually water under high pressure in a so-called primary circuit - reactors PWR and VVER). Refrigerant flows into the steam generator, where it gives off heat from the boiling water of the secondary circuit of lower pressure, and then returned to the reactor. Water vapor ( wet steam, which is dried prior to reaching the turbine, the water molecules in the wet steam at high pressure, destroy the turbine, so the first pass wet steam from the steam generator through the drying system ...
