Draft Revision 4 - December 2012 A. Reinforced and prestressed concrete boiling-water reactor (BWR) containments using the pressure-suppression concept, including the Mark I (lightbulb/torus), the Mark II (over/under), and the Mark III (with horizontal venting between a centrally located cylindrical drywell and a surrounding suppression pool). B. Reinforced concrete pressurized-water reactor (PWR) containments using the pressure-suppression concept with ice condenser elements. C. Reinforced concrete PWR containments designed to function under subatmospheric conditions. D. Reinforced and prestressed concrete PWR dry containments designed to function at atmospheric conditions. E. Reinforced and prestressed concrete PWR or BWR containments using special features or modifications of the above-listed types. As an example, for any application submitted for design certification (DC) that incorporates unique features such as modular construction, passive systems with pools, single foundation for the nuclear island structures, and concrete walls and floors integrally connected to the concrete containment, the applicant needs to provide information such that an adequate review and evaluation can be done. Various geometries have been used for these containments. The geometry most commonly encountered is an upright cylinder topped with a dome and supported on a flat concrete base mat. Although applicable to any geometry, the specific provisions of this Standard Review Plan (SRP) section are best suited to the cylindrical-type containment topped by a dome. Reviews of containments with other types of geometry will make the necessary deviations from this SRP section on a case-by-case basis. The geometry of the containment is reviewed, including sketches showing plan views at various elevations and sections in at least two orthogonal directions. The reviewer examines the arrangement of the containment and the relationship and interaction of the shell with its surrounding structures
