Containment Structure Testing, Modeling, and Degradation


Numerous studies have been conducted at Sandia National Laboratories and around the world to examine the severe accident behavior of containments through containment structural testing and modeling. Large-scale testing has been conducted on both prestressed concrete containments as well as on various steel shell designs. Since the containment includes the entire pressure boundary and not just the steel or concrete shell, some additional testing has been conducted on components (e.g., bellows, hatches). One of the goals of these test programs was to provide data for the calibration of computational models. Therefore, the accompanying computational analyses efforts for a number of the testing programs are also discussed. In addition, a summary of work examining the effects of containment degradation is provided. Various forms of degradation (e.g., liner corrosion) have been observed throughout the U.S. fleet of nuclear power plants. The effects of degradation on the severe accident response are examined in several studies using both deterministic and probabilistic analyses. These efforts describe the effect containment degradation has on the severe accident failure pressures, risks, and consequences.
