REVIEW RESPONSIBILITIES Primary - Organization responsible for structural analysis reviews Secondary - Organization responsible for reviews of material and coolability of the fuel assembly (Appendix D) I. AREAS OF REVIEW This section describes the review of areas relating to all seismic Category I structures other than the containment and its interior structures, and other structures important to safety that may not be classified as seismic Category I. The specific areas of review are as follows: 1. Description of the Structures. The staff reviews the descriptive information, including plans and sections of each structure, to establish that there is sufficient information to define the primary structural aspects and elements relied upon for the structure to perform the intended safety function. The staff also reviews the relationship between adjacent structures, including the separation provided or structural ties, if any. The following describes the major plant structures that are reviewed and the descriptive information reviewed for each: 3.8.4-2 Revision 4 – September 2013 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). Concrete enclosure buildings also protect the primary containment, which may be of steel or concrete, from outside hazards. The enclosure building is usually constructed of either concrete or structural steel and metal siding. If it is a concrete structure, it usually has the geometry of the containment. As applicable, the descriptive information reviewed is similar to that of a concrete containment in accordance with Subsection I.1 of NUREG-0800, Standard Review Plan (SRP), Section 3.8.1. If the building is constructed of structural steel and metal siding, the staff will review the general arrangement of the building, including its foundations,
