When great accidents occur, usually they are the governments and the society that the responsibility of the remediation loads heavy, that in Chernobyl already reached estonteantes U$ 235 billion and still it is very far the recovery of the place. This accident, that liberated the least one hundred times more radiation that the launched atomic bombs on Hiroshima and Nakasaki, had contaminated an area of the size of Switzerland, transformed the city of Pripyat in an inhospitable place and for more than condemned this region to the wild life 300 years. The ONU says that only after two years of studies and research it will be able to understand all the extension of what it was transferred in Fukushima. The great majority of enormous the nuclear plants demand volumes of water, mainly in the processes of cooling of reactors. Part of this water for times is poured in the oceans, having contaminated local biodiversity. In 2003 the Europe had an intense wave of heat for all, and France, Spain and Germany had had that to close or to reduce the production of some plants, face to the low water levels.
The existing nuclear plants must then completely be reevaluated the bases of the projects in all. To process to an ample revision of the security norms and to decree without mercy the descomissionamento of plant with unsafe technologies and/or useful life in ocaso. Specifically, it is needed to determine if these plants are in fact capable to support all the gamma of disasters that can affect them: technological imperfections, human beings, floods, earthquakes and until acts of terrorism. So that he has an expansion of the nuclear energy, the necessary public to restore the confidence in the nuclear industry. To believe that the operators of the nuclear reactors, are public or private, they adopt rigid standards of security. To trust the capacity of the regulators of the rules of the game to execute adequate supervision; to trust that in fact the technological capacity constructs reactors that surpass the vulnerabilities of the models oldest; that these suffer a rigorous process from relicenciamento.
