tems, meet the acceptance criteria given in subsection II. SRP Section 14.3 (proposed) contains procedures for the review of certified design material (CDM) for the standard design, including the site parameters, interface criteria, and ITAAC.87 IV. EVALUATION FINDINGS The reviewer verifies that sufficient information has been provided in accordance with the requirements of this SRP section, and that his the evaluation supports conclusions of the following type, to be included in the staff's safety evaluation report: The staff concludes that the specified design and service combinations of loadings as 88 applied to ASME Code Class 1, 2, and 3 pressure retaining components are acceptable 3.9.3-15 DRAFT Rev. 2 - April 1996 and meet the requirements of 10 CFR Part 50, § 50.55a and General Design Criteria 1, 89 2, 4, 14, and 15. This conclusion is based on the following: 1. The applicant met the requirements of 10 CFR Part 50, § 50.55a and General 90 Design Criteria 1, 2, and 4, 14, and 15 with respect to the design and service 91 load combinations and associated stress and deformation limits specified for ASME Code Class 1, 2, and 3 components by ensuring that systems and 92 components important to safety are designed to quality standards commensurate with their importance to safety and that these systems can accommodate the effects of normal operation as well as postulated events such as loss-of-coolant accidents and the dynamic effects resulting from earthquakes. The specified design and service combinations of loadings, as applied to ASME Code Class 1, 2, and 3 pressure retaining components in systems designed to meet seismic Category I standards, are such as to provide assurance that, in the event of an 93 earthquake affecting the site or other service loadings due to postulated events or system operating transients, the resulting combined stresses imposed on system components will not exceed allowable stress and strain limits for the materials of construction.
