An analysis of a Mark III reactor-containment vessel subjected to a uniformly increasing internal pressure and gravity loads is carried out in order to ascertain the load-carrying capacity of the structure under hydrogen burn. The analysis is conducted by using a nonlinear finite-element model that includes nonlinearities in the strain-displacement relations as well as in the material constitutive equations. In this analysis, the nonlinea behavior of the liner and reinforcement steels is described by a von Mises elastic plastic model with isotropic hardening. Results pertaining to the critical regions of the containment where cracking of the concrete, yielding of the reinforcement bars, and substantial straining of the liner take place are discussed in detail in the text that follows.
