Content:
nts is contained in subsec- tion I.2 of the SRP Section 3.8.3. In addition the documents listed in subsection II.2 of SRP Section 3.8.1 are acceptable for the containment foundation. 3. Loads and Load Combinations The specified loads and load combinations used in the design of seismic Category I foundations are acceptable if found to be in accordance with those combinations referenced in subsection 11.3 of SRP Section 3.8.1 for the containment foundation, and with those combinations listed in subsection II.3 of SRP Section 3.8.4 for all other seismic Category I foundations. In addition to the load combinations referenced above, the combinations used to check against sliding and overturning due to earthquakes, winds, and tornados, and against floatation due to floods, are found acceptable if in accordance with the following: a. D + H +E b. D + H + W c. D + H + E' d. D + H + Wt e. D + F where D, E, W, E', W are as defined in SRP Section 3.8.4, H is the lateral earth pressureand *' is the bouyant force of the design basis flood. Justification should be provided for including live loads or portions thereof in these combinations. 4. Design and Analysis Procedures The design and analysis procedures used for seismic Category I foundations are acceptable if found in accordance with the following: a. The design should consider the soil-structure interaction, hydrodynamic effect, and dynamic soil pressure. b. For seismic Category I concrete foundations other than the containment foundations, the procedures are in accordance with the ACI-349 Code, as augmented by Regulatory Guide 1.142. c. For Category I steel foundations, the procedures are in accordance with the AISC "Specifications...". 3.8.5-6 Rev. 1 - July 1981 d. For the containment foundation, the design and analysis procedures referenced in subsection 11.4 of SRP Section 3.8.1 are acceptable. e. The design report is found acceptable if it satisfies the guidelines contained in Appendix C to SRP Section 3.8.4. f. The
