Yucca Mountain

The projection of the reactors foresees security layers redundant. To attack the evil biggest of the heating, it has a central system of cooling of reactors and some parallel systems of reserve in case of imperfections. An accident of great ratios alone will be able to occur if all these systems to fail at the same time. When adding layers of redundancy, the probability of a catastrophic accident is considered worthless. A reactor can have as many layers of defense how much to desire itself, but if all they could be disactivated by one same event, the defense in depth are engaged. It was what it occurred in Fukushima, with tsunami that interrupted the nuclear cooling of 6 of the 14 plants of the affected region, causing estupor for all Japanese nation.

The nuclear danger does not inhabit only in panes, but in the rejeitos, that can become lethal weapons. Although to produce reduced amounts of rejeitos, some low-level of radiation and until passveis of recycling, it does not have a safe destination for the atomic garbage. Not yet an adjusted place exists in no country of the world to deposit radioactive dejeitos, although studies and intense searches. The proper plant, finda its useful life of surrounds 40 years, with possible supervened of more 20 years, is changedded into a great potential focus of contamination, that is, after producing tons of garbage, also it is changedded into garbage. The only definitive geologic deposit of the radioactive garbage is in U.S.A., in Yucca Mountain, Been of Nevada. Its construction already lasts 25 years, with costs of U$ 38 billion. The residues are densely compact in the subsoil, in swimming pools special and already it has governmental actions to close the place definitively, for pressure of the local inhabitants. Nobody wants atomic garbage in its yard! As much the deactivation of nuclear plants how much the responsibilities and arrangements of compensation for accidents duly are not considered in the total costs of the plants.
