Abstract

To ensure long-term safe and reliable plant operation, equipment operability and availability
must also be ensured by setting a group of processes to be established within the nuclear power
plant. Equipment reliability process represents the integration and coordination of important
equipment reliability activities into one process, which enables equipment performance and
condition monitoring, preventive maintenance activities development, implementation and
optimization, continuous improvement of the processes and long term planning.
The initiative for introducing systematic approach for equipment reliability assuring came
from US nuclear industry guided by INPO (Institute of Nuclear Power Operations) and by
participation of several US nuclear utilities. As a result of the initiative, first edition of INPO
document AP-913, ‘Equipment Reliability Process Description’ was issued and it became a basic
document for implementation of equipment reliability process for the whole nuclear industry.
The scope of equipment reliability process in Krško NPP consists of following programs:
equipment criticality classification, preventive maintenance program, corrective action program,
system health reports and long-term investment plan. By implementation, supervision and
continuous improvement of those programs, guided by more than thirty years of operating
experience, Krško NPP will continue to be on a track of safe and reliable operation until the end of
prolonged life time.
