Content:
rced concrete containments for internal pressure capacity calculations appears in NUREG/CR-6906. NOTE: In applying the analysis methodology to existing containment structures, it is permissible to use as-built material properties for the reinforcing steel and concrete. Sufficient data must be available to establish with reasonable confidence a lower bound, a median, and an upper bound value for the important material parameters. These values must be adjusted for the design-basis accident temperature. For deterministic assessments, the lower-bound values should be used. For probabilistic risk assessment, calculations of failure probability versus pressure should consider the statistical distribution of the material properties. ii.
