REVIEW RESPONSIBILITIES Primary - Structural Engineering Branch (SEB) Civil Engineering and Geosciences Branch (ECGB)1 Secondary - None I. AREAS OF REVIEW The following areas relating to all seismic Category I structures and other safety-related structures that may not be classified as seismic Category I, other than the containment and its interior structures, are reviewed: 1. Description of the Structures The descriptive information, including plans and sections of each structure, is reviewed to establish that sufficient information is provided to define the primary structural aspects and elements relied upon for the structure to perform the safety-related function. Also reviewed is the relationship between adjacent structures, including the separation provided or structural ties, if any. Among the major plant structures that are reviewed, together with the descriptive information reviewed for each, are the following: a. Containment Enclosure Building The containment enclosure building, which may surround all or part of the primary concrete or steel containment structure, is primarily intended to reduce leakage during and after a loss-of-coolant accident (LOCA). from within-the DRAFT Rev. 2 - April 1996 3.8.4-2 containment. Concrete enclosure buildings also protect the primary containment, 2 which may be of steel or concrete, from outside hazards. The enclosure building is usually either a concrete structure or a structural-steel- and-metal-siding building. Where it is a concrete structure, it usually has the geometry of the containment and, as applicable, the descriptive information reviewed is similar to that of a concrete containment as contained in subsection I.1 of Standard Review Plan (SRP) Section 3.8.1. 3 Where it is a structural-steel-and-metal-siding building, the following items are reviewed: general arrangement of the building, including its foundations, wall, and roof; any bracing and lateral ties provided for the stability of the building; the roof
