U.S. Nuclear Regulatory Com mission ND-22-0164 Enclosure Page 2 of 4 ITAAC Statement Design Commitment 2.a) The hydrogen monitors identified in Table 2.3.9-1 are powe red by the non-Class 1E de and UPS system .

Inspections, Tests, Analyses Testing will be performed by providing a simulated test signal in each power group of the non-Class 1Ede and UPS system.

Acceptance Criteria A simulated test signal exists at the hydrogen monitors identified in Table 2.3.9-1 when the non-Class 1E de and UPS system is provided the test signal.

ITAAC Determinati on Basis Testing is performed on the hydrogen monitors identified in the VEGP Unit 3 COL Appendix C Table 2.3.9-1 (Attachment A) to demonstrate they are powe red from the non-Class 1Ede and Uninterruptible Powe r Supply (UPS) system (EDS). This ITAAC performs testing on the hydrogen monitors identified in Attachment A by providing a simulated test signal in the EDS supplying power to the hydrogen monitors.

The Unit 3 component test work orders identified in Reference 1 document completion of power verification ar:tivi ties fr0r.-, thP. !=:OS uninterruptihle power supply (U PS) distrib ution p;:inel to the hydrogen monitors identified in Attachment A. Reference 1 first verifies that power supply cables/wiring are installed and terminated from the applicable EDS UPS power distribution panels to the hydrogen monitors identified in Attachment A using approved construction drawings and cable/wiring termination documentation. Reference 1 then confirms , via cable/wi ring termination inspection documentation, that continuity testing was performed on each of the installed cables/wiring to confirm current flow within the installed cable/wiring. The combination of cable/wiring instal lation and termination verification , with the installed cable/wiring continuity testing , confirms that the hydrogen monitors identified in Attachment A are powered by their respective EDS power supply.

The Unit 3 component test package work orders documented in Reference 1 confirm that a simulated test signal exists at the hydrogen monitors identified in Table 2.3.9-1 when the EDS is provided the test signal.

Reference 1 is availabl e for NRC inspection, as well as the Unit 3 ITAAC 2.3.09.02a Completion Package (Reference 2) .

ITAAC Findi ng Review In accordance with plant proced ures for ITAAC completion , Southern Nuclear Operating Company (SNC) pe rformed a review of all lTAAC findings and associated corrective actions.
