Nuclear Power is a source of energy which has many benefits. Nuclear energy is less expensive because it is based on uranium which is very accessible. With little amount of uranium a great amount of energy can be produced. It is a reliable source to rely on as there is significant amount of it on the Earth’s crust.(1)
One important advantage is that producing energy using Nuclear Power does not give off Greenhouse gases. Green house gases are gases like carbon dioxide and sulphur dioxide which are contributing to the Greenhouse effect or Global Warming. The biggest advantage of Nuclear Power is the discoveries made in Nuclear Medicine, such as cancer therapy, CAT scan and MRI machines and the use of irradiation of food to kill bacteria.(2)
Nuclear Power has been used in the last hundred years for the manufacture of Nuclear Weapons like A-Bombs (atomic bombs) and H-Bombs (hydrogen bombs). Nuclear Weapons are weapons of mass destruction. A single weapon can be capable of destroying of seriously disabling an entire city. In the history of warfare Nuclear Weapons have been used on two occasions, both during the closuring days of World War II in Hiroshima when a devise called ‘Little Boy’ was dropped and then three days later one in Nagasaki called ‘Fat Man’.(3)
It is a good idea to possess Nuclear Weapons if you are a ‘Super Power’. If a country feels threatened it can rely on Nuclear Weapons to protect them from the enemy. Examples of ‘Nuclear Super Powers’ are USA, Russia, United Kingdom and France.
Nuclear Weapons have many disadvantages. The use of them can lead to a world crisis as every time a bomb explodes the lives of millions of people are affected and those close to the explosion are vaporised in a split second. Nuclear Weapons are very expensive to manufacture even though the uranium is accessible.
Nuclear Power has many disadvantages too. Nuclear Plants are on of average 75% to 80% reliable. If an accident occurs, in USA for example, according to a 1982 study done by Sandia National Laboratories, it would result in deaths of thousands of people, latent cancers and the loss of and billions of dollars.(4)
We have all seen movies where whole cities have to be evacuated when a Nuclear Power plant is about to explode. That is fiction but can become reality.
One major disadvantage of Nuclear Power is that it makes variable amounts of radioactive waste. This waste is causing big problems for the world storage because of its irradiation. The nuclear waste has to be stored over a hundred years and the waste remains hot for thousands of years.
Some people say Nuclear energy is cheaper...
