d, the necessary modifications to this SRP section are made on a case-by-case basis. iv. Steel components of concrete containments that resist pressure and are not backed by structural concrete (e.g., the drywell head in a BWR) The geometry of the containment, including sketches showing plan views at various elevations and sections in at least two orthogonal directions are reviewed. The arrangement of the containment and the relationship and interaction of the steel containment shell with its surrounding shield building and with its interior compartments, walls, and floors to determine the effect that these structures could have upon the design boundary conditions and the expected behavior of the steel containment shell when subjected to the design loads are reviewed. B. The general information related to the containment shell including the following are reviewed: i. The foundation of the steel containment, including the following: (1) If the bottom of the steel containment is continuous through an inverted dome, the staff will review the method by which the inverted dome and its supports are anchored to the concrete foundation. SRP Section 3.8.5 covers the concrete foundation. (2) If the bottom of the steel containment is not continuous, and a concrete base slab, topped with a liner plate, is used for a foundation, the staff will review the method of anchorage of the steel cylindrical shell walls into the concrete base slab and the connection between the floor liner plate and the steel shell. SRP Section 3.8.1 provides review guidance. 3.8.2-3 Revision 2 - March 2007 ii. The cylindrical portion of the shell, including major structural attachments to the inside and outside surface of the shell, such as beam seats, pipe restraints, crane brackets, shell stiffeners (if any) in the hoop and vertical directions, and external cooling flow channels (e.g., AP600, AP1000). iii. The dome of the steel containment, including any reinforcement at the dome/cylinder junction,
