x D to SRP Section 14.3 for verification of the performance of these valves. These may be performed as part of the pre-operational test program. Tier 2 information should be provided that defines that these tests will be conducted under maximum achievable pre-operational conditions and describes the analyses that will be performed to show how the test results demonstrate that the valves will function under design basis conditions (See Tier 2 Section 3.9.6). Since significant operating problems with other types of valves, or with pumps in general, the proper operation of these components may be DRAFT Rev. 0 - April 1996 14.3.3-8 implicitly tested, if applicable, as part of other functional tests in the system ITAAC. They may also be tested in the pre-operational or power ascension test program. III. REVIEW PROCEDURES 1. Follow the general procedures for review of Tier 1 contained in the Review Procedures section of SRP Section 14.3. Ensure that the DCD is consistent with Appendix A to SRP Section 14.3. Review responsibilities may be consistent with those in Appendix B to SRP Section 14.3. 2. Ensure that all Tier 1 information is consistent with Tier 2 information. Figures and diagrams should be reviewed to ensure that they accurately depict the functional arrangement and requirements of the systems, and all important SSCs are treated appropriately. Reviewers should use the Review Checklists in Appendix C to SRP Section 14.3 as an aid in establishing consistent and comprehensive treatment of issues. 3. Ensure that Tier 1 clearly delineates the important aspects of piping design, specifies its applicability to the standard design, and establishes appropriate acceptance criteria. ASME code classification, safety classification, and seismic classification of the piping systems should be clearly indicated on the figures, or described in the design descriptions. These should be consistent with DCD Tier 2 Section 3.2. Ensure that system boundaries and interfaces are
