The probability of failure of reactor vessel with semi-elliptic crack after warm pre-stressing was assessed taken into account the scatter of mechanical properties and loading parameters by Monte-Carlo with importance sampling and first-order reliability method based on limit-state functions from FITNET procedure. The failure assessment diagrams were obtained by means of Monte-Carlo simulations for different crack depth and variable internal pressure.

    The K-out-of-N configuration is a typical form of redundancy techniques to improve system reliability, where at least K-out-of-N components must work for successful operation of system. When the components are degraded, more components are needed to meet the system requirement, which means that...
