Analytical Calculation for Reliability Validation of Nuclear Power Plants

An analytical calculation for validating the requirements of the means used for monitoring the technical condition of equipment and systems of nuclear power plants is presented. The theoretical approaches for checking the compliance of reactor facilities with established technical requirements are presented. The characteristic parameters describing the state of a nuclear power plant and the qualitative indications for which quantitative assessments are not used are presented for the technical states of reactor facilities. A list of the parameters and indices as well as the limits of admissible changes is presented in the procedure for each concrete object. It is shown that the monitoring of the technical state consists of the monitoring of all equipment and systems, in order to obtain information about the actual technical state of the nuclear power plant and its compliance with the established requirements of operational and repair documentation, and determination of the type of technical state.
