Abstract
The performance and long-term operational integrity of containment sys tems and components is being challenged as many of the world's nuclear plants progress into the second half of their design lives. As time i n service increases, so does the likelihood of component failure due t o long term degradation. By observing trends in containment degradatio n, potential weaknesses can be anticipated and corrected, minimizing i nterruptions in operations, increasing safety and improving the plant' s life extension outlook. One such trend, affecting containment penetr ation flexible metallic bellows that are subject to cyclic loading, is beginning to appear in some BWR plants.
