s demonstrate that the valves will function under design basis conditions (See DCD Tier 2, Section 3.9.6). Where indicated by significant operating experience with specific pumps or valves, the proper operation of these components in light of that operating experience should be explicitly demonstrated as part of ITAAC functional tests. G. Installed Configuration. ITAAC should verify the installed configuration of each system and its components within the Tier 1 scope. The Design Commitment should specify that the installed configuration of the system, including its flowpath, is consistent with installation geometric specifications such that the system’s safety functions can be achieved. The ITA should specify that an inspection of the as-built system will be performed to verify the installed configuration, including the flowpath. The Acceptance Criteria should specify that the system installed configuration, including the flowpath, of the components listed in the applicable 14.3.3−19 Draft Revision 1 – September 2018 ITAAC table is consistent with installation geometric specifications such that the system’s safety functions can be achieved. Tier 2 information should indicate that verification of the installed configuration of the system includes verifying that the system and its components are installed in a manner that supports the safety functions for which the system is intended, consistent with installation geometric specifications. This verification should include visual inspection (e.g., walkdown) of the systems, including their flowpath, and may be performed in conjunction with other preoperational activities. Examples of the geometric verification adequate to complete this ITAAC include confirmation of valve orientation, inspection of installation, verification 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
