Resumo

Some nuclear power plants around the world have an advanced operating time. With the operating time of 40 years, these plants should be subject to the decommissioning process. This fact implies in a considerable investment and the loss of an important source of energy. In addition to the factors of safety involved, this work is one of the pioneers in the search for methodologies that can ensure that the supervision, maintenance and replacement of components more sensitive to the “aging process” result in the increased safety of an installation, and consequently, in the guarantee that it can to extend its normal time of operation.
