Fig 1 shows the few instances of nuclear accidents as compared to the cumulative years the reactors have been in operation. The report will focus on the underlying causes involved in the three disasters in order to reveal the most effective ways of ensuring that human life is not lost again due to nuclear accidents.
The accident at Three Mile Island (TMI 2) that occurred in 1979 was caused by a combination of equipment failure and the inexperience of the plant operators (World Nuclear Association 2013 p. 1). The nuclear professionals failed to understand the heat condition of the reactor at pivotal moments during the event (World Nuclear Association 2013 p.1). As a result, their response was ineffective. A gradual loss of cooling water to the heat-producing core in the reactor caused a partial melting of the fuel rod cladding. In addition, the uranium fuel was also affected. As a result, a small amount of radioactive material was released.
The Chernobyl accident was caused by a flawed reactor design. The accident occurred during a test for emergencies because operators were trying to determine what would happen to a reactor if a power outage occurred (Mara 2011, p. 15). The reactor had a large positive void coefficient. The void coefficient refers to the response of a nuclear reactor in case of increased steam formation in the water coolant.
The second flaw involved the design of the rods that were expected to slow down reactions in the rector. The lower part of the control rods was made of graphite. In addition, it was shorter than the conventional design. The design led to the increase of power output. The practice achieved unintended results, a fact that was clearly unknown to the reactor operators.
In contrast, the Fukushima power plants had an excellent design. When the authorities learned about the impending storm, they executed a

Many of these societal issues impact a large majority of the population in some respect and the governmental and institutional decisions taken with regards to these spark intense emotions. These issues can range from health, environmental, technological and general societal problems- both public and expert opinions are expressed compellingly and backed by various studies and research done on them.
Unlike fossil fuels, nuclear energy is a clean form of energy that does not contribute to the depletion of the ozone layer. Nuclear energy comes from the chemical reaction of different highly volatile chemicals often resulting in the production of heat and water, some such as anti-matter reacts with any form of matter including the oxygen to result in absolutely nothing.
These countries are France, Japan, and the United States. This is despite the fact that there are 439 nuclear reactors for power generation scattered across 31 countries. Statistics have shown that this
Nuclear power is credited as an alternative to those countries that do not produce petroleum product. It reduces overreliance on import of these products. However, others are against nuclear power to because it affects both human and environment. This
This steam is then made to turn turbines which produce electrical energy. The strong interactive forces existing in the nucleus i.e. the nuclear power can be used to produce electricity because these forces are one of the greatest forces
The author insists that in case nuclear reaction in the reactors is needed to be stopped urgently (as in the case of an accident) safety injection system can be used to bring the reaction to a halt. This is usually done by injecting a fluid (liquid) directly into the core of the reactor that usually absorbs the neutrons.
The boiling water reactors were the first to be developed while the pressurized water reactors came much later. In both systems, steam is generated which drive the turbines. Thereafter, the turbines power the generators to produce electricity.
This paper discusses that countries should generate and use nuclear energy, because of associated benefits. The first benefit of the nuclear energy is that it is a reliable power source. The second benefit is that nuclear power is a relatively cheap power source.
