justification. G. The stiff and soft spots evaluation in the foundation soil to maximize the bending moments used in the design of the foundation mat. H. Description of the design details of critical locations, such as the junction of sidewall and base mat and the junctions of base mat to sumps. I. Detail explanation of the load path from all superstructures to the foundation mat to the subgrade. Discussion of any unique design features that occur in the load path (e.g., any safety-related function that the tendon gallery may have as part of the foundation in a prestressed containment or the connection of any internal structures to a steel containment and its supporting foundation). J. Explanation of how loads attributable to construction are considered in the design. Some examples of items to be discussed include the excavation sequence and loads from the construction sequence of the foundation mat and walls, as well as the potential for loss of subgrade contact (e.g., because of loss of cement from a mud mat) that may lead to a differential pressure distribution on the mat. 5. Structural Acceptance Criteria. For the loading combinations referenced in the first paragraph of Subsection II.3 of this SRP section, the allowable limits that constitute the acceptance criteria are referenced in Subsection II.5 of SRP Section 3.8.1 for the containment foundation and in Subsection II.5 of SRP Section 3.8.4 for all other foundations. In addition, for the five other load combinations in Subsection II.3 of this SRP section, the factors of safety against overturning, sliding, and flotation are acceptable if found to be in accordance with the following: 3.8.5-10 Revision 2 - March 2007 Minimum Factors of Safety For Combination Overturning Sliding Flotation a. ----------------------- 1.5 1.5 --- b. ----------------------- 1.5 1.5 --- c. ----------------------- 1.1 1.1 --- d. ----------------------- 1.1 1.1 --- e. ---------------------- --- --- 1.1 6.
