rification of adequate sloping of piping in accordance with design provisions, and verification of access. To the extent other ITAAC verify the installed configuration of an SSC, as described above, a separate ITAAC for doing so is not needed. However, the mere fact that other ITAAC apply to a particular SSC is not an indication that the installed configuration ITAAC may be omitted. Rather, the staff should consider whether two or more ITAAC verify the same substance and are therefore redundant. H. Regulatory Treatment of Non-Safety Systems (RTNSS). In SECY-95-132, “Policy and Technical Issues Associated with the Regulatory Treatment of Non-Safety Systems (RTNSS) in Passive Plant Designs,” as accepted by the Commission in its Staff Requirements Memorandum dated June 28, 1995, the NRC specified the policy regarding the functional design, qualification, and inservice testing of RTNSS pumps and valves for new nuclear power plants with first-of-a-kind passive core and containment cooling systems. For a new nuclear power plant, ITAAC should cover equipment within the scope of the RTNSS program that provide the first line of defense for the passive cooling systems. These ITAAC should provide for the verification of RTNSS equipment to perform their intended function, including dynamic, environmental, and functional capability. I. Design Reliability Assurance Program (D-RAP). ITAAC should verify the implementation of the D-RAP for the nuclear power plant. The Design Commitment for the D-RAP should specify that the design of SSCs within the scope of the reliability assurance program (RAP) is consistent with the risk insights and key assumptions (e.g., SSC design, reliability, and availability). The ITA should specify that an analysis will confirm that the design of all RAP SSCs has been completed in accordance with applicable D-RAP activities. The Acceptance Criteria should specify that all RAP SSCs have been designed in accordance with the applicable reliability
