Characteristics and development of risk informed in-service inspection (RI-ISI) methodology for nuclear piping systems are examined in this report. This involves applying the combination of probabilistic fracture mechanics (PFM) and Markov system analyses, and by refining an existing and commonly applied risk analysis procedure. The applicability of the developed risk matrix approach was examined as a pilot study performed to a piping system in an existing Finnish nuclear power plant (NPP)
