ABSTRACT
Nuclear containment structures for light-water reactors, for both boiling water reactors (BWRs) and pressurized water reactors (PWRs) in the United States, have evolved over the last 50 plus years. Types of containment structures from prestressed post-tensioned concrete containment vessels (PCCVs) to multi-barrier containment (MBC) structures have led the way. Various containment structures will be addressed from early ones, to advanced containment structure concepts. Dry, pressure suppression, and advanced containment concepts will be discussed with current applications. New passive containment design concepts, for new-generation reactors, will also be addressed.
