Content:
is set at a value greater than one-third of the SSE, an analysis and design must be performed to demonstrate that the applicable stress, strain, and deformation limits are satisfied. SRP Section 3.7.3 describes acceptable analytical methods that are used to determine the seismic response of subsystems in terms of stresses, strains, and deformations. These responses are combined with the structural responses from other loads in accordance with the criteria in SRP Section 3.8. The criteria in SRP Section 3.7.3 ensure that the effects of SSI and expected duration of the earthquake are appropriately included in the evaluation. In addition, criteria is provided to indicate when the effects of the OBE are required to be considered explicitly in the seismic design of the subsystems. Meeting these requirements provides assurance that appropriate methods will be used to determine the structural response of subsystems, under the SSE and OBE (if applicable), which will ensure that they will remain functional within applicable acceptance limits. III. REVIEW PROCEDURES The reviewer will select material from the procedures described below, as may be appropriate for a particular case. These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II.
