2. The FPS piping shown on Figure 2.3.4-2 remains functional following a safe shutdown earthquake.

Inspections/Tests/Analvses i) Inspection will be performed to verify that the piping shown on Figure 2.3.4-2 is located on the Nuclear Island.

Acceptance Criteria i) The piping shown on Figure 2.3.4-2 is located on the Nuclear Island.

ITAAC Determination Basis Multiple ITAAC were performed to demonstrate that the Fire Protection System (FPS) piping shown on Figure 2.3.4-2 of the Combined License(COL) Appendix C remains functional following a safe shutdown earthquake. The subject ITAAC requires an inspection to verify that the piping shown on COL Appendix C, Figure 2.3.4-2 is located on the Nuclear Island, which is a seismic Category I structure.

To assure that the FPS piping shown on COL Appendix C, Figure 2.3.4-2 remains functional following a safe shutdown earthquake, all the pipelines and inline components/valves are designed to be located on the seismic Category I Nuclear Island. In accordance with procedure NCSP02-24(Reference 1), an inspection was conducted of the FPS to confirm the satisfactory installation of the piping system required to remain functional following a safe shutdown earthquake. The inspection included verification of the installed piping location (Building and Room).

The inspection results are documented in the Unit 3 Principal Closure Document(Reference 2) which confirmed that the piping shown on COL Appendix C, Figure 2.3.4-2 is located on the Nuclear Island and meets the ITAAC acceptance criteria.

Reference 2 is available for NRC inspection as well as the Unit 3 ITAAC Completion Package (Reference 3).
