Probabilistic descriptions of resistance of safety-related structures in nuclear plants

Abstract Calculations of reliability of safety-related nuclear plant structures require a knowledge of the probability distributions that describe their resistance. This study considers the applicability of existing statistical data for describing the resistance of steel and reinforced concrete nuclear plant structures. Probability distributions are recommended which can be used in assessing the reliability of containments and other Category I structures, developing fragilities, and selecting appropriate resistance criteria for probability-based structural design.
