In this research, called the “the maintenance index,” was proposed to evaluate the reliability of nuclear power plant safety systems by taking into account periodic maintenance of the systems. The change in reliability as a result of changing activity is estimated by this index. The Maintenance Index offers a more comprehensive evaluation of nuclear power plant safety.
