Nuclear is an energy source that is widely used in the world. The history of nuclear energy can be traced back to year 1930’s. First discovery of radioactivity was happened back to 1896 by Henri Becquerel when he wrapped a photographic plate and along with a crystal which contained uranium (Chater J, 2005). After a while, the plates emitted an invisible nuclear emanation which caused by the crystal uranium. The discovery then continues and evolves to a nuclear fission. This evolution continues to another level by the discovery of neutron by James Chadwik, as a tool for nuclear energy. The figure of nuclear fission and neutron is shown below:-
There are four main elements in nuclear atom. According to Pearson J (2008), the elements are nucleon (refer to neutron or proton in an atom), isotope (two nucleon which differs in the number of neutron), isotone (converse of isotope) and isobar (a nucleon which has the same amount of mass with the atom). These four elements combined together and creates nuclear atom. Nuclear atom then react its force and produces energy (electrical charge) and leftover neutron or waste (radiation). A figure of the reaction is shown below:-

As we know that nuclear is an energy source, a key energy to sustain the human’s daily life and survival. Nuclear energy is cheaper to use and operate rather than fossil fuel energy. According to Diesendorf M (2010), the cost of nuclear energy per power station is US$ 7.5c/KWh, which is lower than fossil fuel by 8 percent. Plus, the fuel-based energy like diesel can be run out by the time of 2035, in terms of demands and resources. Nuclear energy can generate electricity two and a half times more than oil-based energy. A figure of comparison is shown below:-
World Electricity Generation by 2006
According to this statistics, we can predict that the earth cannot produce and sustain a sources needed for oil, coal and gas. This is because the composite and other material used to create those three resources will be run out in the future. On the other hand, hydro and nuclear based energy can sustain longer because the earth nature gives an advantage to produce energy. For example, hydro based energy generates electricity through water dam that using water flow to power up its dynamo which produce electrical energy. At the same time, nuclear energy constantly produces electricity because the radioactive atom was depending on uranium which our mother nature constantly produces every day.
In conclusion, nuclear energy is a long lasting energy that can be used to its fullest by any means necessary. This is because the ingredient and elements is hardly run out rather than using oil, gas and coal to generate electricity energy. Nuclear energy is the answer for the future generation to sustain life those so demanding years after years.
