ng 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 indicated clearly in Tier 1, and that the figures are in accordance with the legends. 4. The reviewer should ensure that appropriate guidance is provided to other branches such that piping design issues in Tier 1 are treated in a consistent manner among branches, especially applicable standard ITAAC and piping issues for figures. 5. Ensure that standard ITAAC entries in Appendix D to SRP Section 14.3 related to piping systems and components are included where appropriate in the systems of the standard design, in particular, the basic configuration ITAAC (for dynamic qualification of SSCs and welding), hydrostatic test ITAAC, MOV ITAAC, POV ITAAC, and check valve ITAAC. Ensure adequate supporting information is in Tier 2, generally Chapter 3 and the initial test program in Section 14.2. 6. Ensure that design features from the resolutions of selected policy and technical issues are adequately addressed in Tier 1, based on safety significance. Ensure that the appropriate Commission guidance, requirements, bases and resolutions for these items are documented clearly in the SER. 7. Ensure that any Tier 2* information is clearly designated in Tier 2, and consider expiration of these items at first full power, if appropriate. The staff's basis for designating the information as Tier 2* and the rationale for its decision that it requires prior NRC approval to change should be specified in the SER (See also the discussion in Appendix A to SRP Section 14.3). 14.3.3-9 DRAFT Rev. 0 - April 1996 8. Ensure appropriate interface with the secondary review branches listed in the "Areas of Review" section above (SPLB and SRXB). IV. EVALUATION FINDINGS Each review branch verifies that sufficient information has been provided to satisfy the requirements of this SRP section, and concludes
