ations occur, they are identified and the justification is evaluated. Valve opening sequence effects should include the worst-case load combination and forcing functions should be justified with valve opening time data. The review will consider 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 reasonable assurance of structural integrity of supports and of operability of active components that interact with component supports. The reviewer verifies that the applicant's SAR 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. 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. 4. For review of a DC application, the reviewer should follow the above procedures to verify that the design, including requirements and restrictions (e.g., interface requirements and site parameters), set forth in the final safety analysis report (FSAR) meets the acceptance criteria. DCs have referred to the FSAR as the design control document (DCD). The reviewer should also consider the appropriateness of identified COL action items. The reviewer may identify additional COL action items; however, to ensure these COL action items are addressed during a COL application, they should be added to the DC FSAR. For review of a COL application, the scope of the review is dependent on whether the COL applicant references a DC, an early site permit (ESP) or other NRC approvals (e.g., manufacturing license, site suitability report or topical report). For review of both DC and COL applications, SRP
