Nuclear Energy
A nuclear power plant, as all others, uses fuel to produce steam that will generate electricity through a turbine. The difference lies in the fuel. In this type of plants, Uranium is usually used. When the nucleus of a Uranium atom is split, two or three neutrons are released and will collide with other atoms. More energy is released each time another atom splits, this phenomenon is called "chain reaction". This process occurs in the reactor, a cylindrical body enclosed by a reflector and a thermal shield. Its main parts are the fuel rods, made of uranium, the moderator, made of graphite which helps maintain the chain reaction, and the control rods which are made of boron-10 or cadmium. These control rods, when pushed inside the reactor, absorb most of the fission neutrons.
Advantages:
-
Relatively low operation costs
-
Stable production of electricity (base load)
-
Low carbon dioxide emissions
-
Mature technology
Disadvantages:
-
High construction costs
-
High risk if an accident happens
-
Difficult management of radioactive waste
-
Centralized power source
