SRP section. Where deviations occur, they are identified and the justification is evaluated. Valve opening sequence effects must consider the worstinclude the worst-case load combination possible and forcing functions must be justified with valve 86 opening time data. The review is based in part on comparisons with prior acceptable designs tested in operating plants. 3. Component Supports The objective in the review of component supports is to determine that adequate attention has been given the various aspects of design and analysis, so that there is assurance as to structural integrity of supports and as to operability of active components that interact with component supports. The reviewer should be assured that the applicant's PSAR contains discussions and commitments to develop and utilize a snubber operability assurance program containing the elements specified in paragraphs (1) through (6) of subsection II.3.b of this SRP section. A commitment to provide in the FSAR the information specified in paragraph (7) of subsection II.3.b of this SRP section is sufficient for the CP review stage. During the OL review the FSAR should contain summaries in sufficient detail to verify the PSAR commitments. The structural integrity of the three types of component supports described in subsection I.3 of this SRP section are reviewed against the criteria and guidelines of subsection II.3 of this SRP section. For standard design certification reviews under 10 CFR Part 52, the procedures above should be followed, as modified by the procedures in SRP Section 14.3 (proposed), to verify that the design set forth in the standard safety analysis report, including inspections, tests, analysis, and acceptance criteria (ITAAC), site interface requirements and combined license action items, 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
