Content:
mitted for DC use a single foundation mat for the nuclear island structures. For such designs, attention is given to bending, shear, and similar factors in the base mat that are attributable to uneven settlement, construction sequence, and mat flexibility. The review also considers the design of the junction of the sidewall and base mat, as well as stiff or soft spots in the underlying soil. Site-specific soil-bearing capacities are reviewed as part of SRP Section 2.5.4. 5. Structural Acceptance Criteria. The review assesses the foundation for its capability to receive loads from the structure and to transmit loads to the soil media, with appropriate safety margins. The review addresses the design limits imposed on the various parameters that serve to quantify the structural behavior of each foundation, emphasizing the extent of compliance with the allowable limits delineated in Subsection II.5 of this SRP section. The review includes factors of safety against overturning and sliding to ensure adequate safety margins. 6. Materials, Quality Control, and Special Construction Techniques. The review assesses information on the materials used in the construction of Seismic Category I foundations. Among the major materials of construction reviewed are the following: A. Concrete ingredients B. Reinforcing bars and mechanical splices C. Structural steel D. Rock anchors, including any prestressing system The review includes the quality control program proposed for the fabrication and construction of Seismic Category I foundations, including nondestructive examination of the materials to determine physical properties, placement of concrete, and erection tolerances. The review addresses any proposed special construction techniques on a case-by-case basis. In addition, for Seismic Category I foundations other than containment, the following information should be provided: A. The extent to which the materials and quality control programs comply with ACI 349, with additional
