How a Nuclear Power Plant Works

Introduction

The thermal power station where nuclear energy is transformed into heat energy for use in generating stream for turbines, as a result, impel generators which generate electric power or electricity is known as Nuclear power plant. By the year 2012, there are about 439 nuclear plants is operating across the world. These plants are generally regarded as to be load stations that are preeminent suited to invariable production of power.

The nuclear power plant is the deepest threat for human and placed on the between the greatest anticipation of humanity. On the other hand, nuclear power plant offers an alternative source of energy, which solves the problem of fossil dependence of fuel. However, nuclear power plant also resulted in disastrous effects such as in Japan, the stream of radioactive as a result of quake-ruptured.

Discussion

The foremost purpose of a nuclear power plant is to generate electrical energy. In order to generate electric energy, a nuclear power plant requires heat source to simmer water that turn out into the stream. Later on, the stream twist a turbine then this turbine spins an electric generator and as a result, the generator produces electric energy. In the plant of fossil fuel, the burning oil, coal or gas is a source of heat. However, the source of energy in a nuclear power plant is a nuclear reactor. Even though, the process of nuclear power plant is simple but its working is complicated comparatively.

To understand the working of nuclear power plant it is essential to first look at the process. Uranium is an act as a fuel for a nuclear reactor, but not any uranium. Nearly all atoms of uranium (99.3 percent) comprise of a nucleus with positively charged 92 protons and 146 neutrons that are uncharged; increasing the number of protons and neutrons, these particles posses a total proton and neutron of about 238. This number is known as atomic number that refers to 238 of uranium to this nucleus or simply U-238. Conversely, it is not necessary that all atoms of uranium have 146 neutrons; for instance, 0.7 percent contains 143 neutrons, hence symbolize as U-235. In spite this, both U-235 and U-238 are uranium, but posses' distinct characteristics. The most prominent difference is that U-235 suddenly fissions or splits, generating fission products (two smaller nuclei) in addition create two to five neutrons. ...
