REVIEW RESPONSIBILITIES Primary - Organization responsible for structural analysis reviews Secondary - None I. AREAS OF REVIEW This section describes the review of areas relating to concrete containments or to concrete portions of steel/concrete containments, as applicable. The specific areas of review are as follows: 1. Description of the Containment. The staff reviews the descriptive information, including plans and sections of the structure, to establish that sufficient information is provided to define the primary structural aspects and elements relied on to perform the containment function. In particular, the review identifies the type of concrete containment and examines its structural and functional characteristics. The following are among the various types of concrete containments reviewed: 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). 3.8.1-2 Revision 2 - March 2007 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
