The safety of nuclear power generation - Essay Example 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

Affirmative action debate pt2 - Thesis Example The enforcement of affirmative action in admission into universities and higher education for those minority groups in the community will act to motivate those oppressed by the discrimination to join in the campaign for its implementation and to work even harder in school. Children of immigrant parents and children from poor families will benefit from the affirmative action. Awareness creation campaigns can be carried out through the media and at the local government level to ensure that the minority groups understand how they can benefit from the action and can therefore support the debate of implementing this action in all institutions of higher education. There has been existing stereotypes that only whites are high achievers and the elites of the US society. This has been majorly because the other races have not been having equal access to higher education equally as the white people. If affirmative action is enforced therefore, this will soon change and the stereotypes will be abolished. One way of ensuring this is by having the stereotyped races sign petitions for the implementation of this policy. If the signatures are more, the policy can be passed to be a law for all states and all institutions of higher learning. In most employment sectors (especially the prestigious jobs), there is domination by certain genders only and the other minority gender (mostly women) are crowded in lesser positions of authority. This has been the case because fewer women have been accessing certain causes in universities and colleges which may lead them to authority positions in the job market. Most women are concentrated in art courses, home economics and secretarial courses, whereas men are in the managerial and science courses. If affirmative action is present in admission into these institutions, there can be an equal number of men and women in certain professionals hence reducing the discrimination and
