U.S. Nuclear Regulatory Commission ND-21-0143 Enclosure Page 2 of 3 ITAAC Statement Design Commitment 8.c) The PXS provides PCS makeup, boration, and safety injection during design basis events.

Inspections/Tests/Analvses iii) Inspections of the routing of the following pipe lines will be conducted:

- CMT inlet line, cold leg to high point

- PRHR HX inlet line, hot leg to high point.

Acceptance Criteria iii) These lines have no downward sloping sections between the connection to the PCS and the high point of the line.

ITAAC Completion Description Multiple ITAAC are performed to demonstrate that the Passive Core Cooling System (PXS) provides Reactor Coolant System (PCS) makeup, boration, and safety injection during design basis events. This ITAAC requires that inspections be conducted to verify that the routing of the Core Makeup Tank(CMT)inlet lines from the cold leg and the Passive Residual Heat Removal Heat Exchanger(PRHR HX)inlet line from the hot leg have no downward sloping sections between the connection to the PCS and the high point of the lines.

The inspection of the routing of each CMT and PRHR HX inlet lines is performed during a walk-down of the as-built lines in accordance with the site walk down inspection procedure (Reference 1). When required to confirm the downward slope or lack of a downward slope, the slope of the lines is determined using survey equipment in accordance with site procedures (Reference 2).

The inspection results are documented in the Unit 4 inspection report (Reference 3) and determine that each CMT and the PRHR HX inlet lines have no downward sloping sections between their connection to the PCS and their respective high point of the line which meets the ITAAC acceptance criteria.

References 1, 2 and 3 are available for NRC inspection as well as the Unit 4 completion package (Reference 4).

U.S. Nuclear Regulatory Commission ND-21-0143 Enclosure Page 3 of 3 List of ITAAC Findings In accordance with plant procedures for ITAAC completion, Southern Nuclear Operating Company(SNC) performed a review of all findings pertaining to the subject ITAAC and associated corrective actions. This review found there are no relevant ITAAC findings associated with this ITAAC.
