Introduction

Nuclear energy usually means the part of the energy of an atomic nucleus, which can be released by fusion or fission or radioactive decay.

Nuclear Fission

Nuclear fission works by splitting the atoms apart to produce smaller atoms, and as a result energy is released. Nuclear fission is used in nuclear power plants to generate electricity through the splitting of the nuclei of uranium atoms.

Nuclear Fusion

When atoms are joined together to form a larger atom is commonly referred to as nuclear fusion. The sun produces energy through nuclear fusion where the nuclei of hydrogen atoms are fused into helium atoms.

Basic principles

The basic principle of operation of a nuclear power plant is based on obtaining heat energy through nuclear fission core combustible atoms. With this heat energy, which have a vapor of water, will convert into mechanical energy in a turbine, and finally convert mechanical energy into electrical energy by a generator.

Nuclear reactor

A nuclear reactor is an installation capable of initiating, controlling and maintaining nuclear reactions (fission usually) chain occurring in the core of the facility.
