Concrete containment analysis including thermal effects

Pretest predictions were made by the staff of the Engineering Mechanics Program at ANL for the response of the 1:6-scale reinforced concrete containment model that was tested to failure by liner tearing and leakage at the Sandia National Laboratories. Questions have been raised in regard to possible effects of temperature in combination with internal pressure on the behavior of the model. Specifically, if the containment had been subjected to elevated temperature as well as internal pressure, what differences in pressure capacity, failure mechanism and location would have been predicted when compared to the analysis of internal pressure alone. The purpose of this paper is to address these questions. 3 refs., 9 figs
