3. The lighting fixtures located in the MCR utilize seismic supports.

Inspections/Tests/Analyses i) Inspection will be performed to verify that the lighting fixtures located in the MCR are located on the Nuclear Island.

ii) Analysis of seismic supports will be performed .

Acceptance Criteria i) The lighting fixtures located in the MCR are located on the Nuclear Island .

ii) A report exists and concludes that the seismic supports can withstand seismic design basis loads .

ITAAC Determination Basis Following installation of the Main Control Room (MCR) lighting fixtures , an inspection was performed to verify the lighting fixtures were located on the Nuclear Island . Additionally , an analysis of the lighting fixture supports was performed, and a report exists that concludes the lighting fixture seismic supports can withstand seismic design basis loads.

The inspection of the MCR lighting fixtures is performed in accordance with Functional Arrangement Scoping Process procedure ND-RA-001-012 (Reference 1) to confirm the lighting fixtures are located on the Nuclear Island . Detailed design drawings identified in SV4-ELS-ITR-800630 (Reference 2) are used to confirm the MCR lighting fixtures are installed in accordance with the design requirements . The inspection includes verification that each lighting fixture is installed in the correct location and the mounting of the fixture complies with the seism ic design details. The result of the inspection is documented in a report for Unit 4 (Reference 2) . The report concludes the lighting fixtures are located on the Nuclear Island.

An analysis of the lighting fixture seismic supports was performed to confirm the supports can withstand seismic design basis loads . The MCR lighting fixtu re supports were designed as Seismic Category I Equipment. The supports consist of steel unistrut channels welded to the ceiling of the MCR and steel chains that attach the light fixture to the unistrut channels . The seismic loading conditions are established using the AP1000 seismic floor response spectra and the equivalent static load method of analysis described in the Vogtle 3&4 Updated Final Safety Analysis Report (UFSAR) (Reference 3) . Lateral loads acting on the support chains are considered negligible based on guidance from the American Society of Civil Engineers (ASCE)

Standard 7-05 (Reference 4) . Structural integrity is demonstrated by calculating and concluding the maximum seismic loads are less than or equal to the applicable design code allowable limits. The results of the analysis are documented in APP-SH25-S3C-002 (Reference 5) and conclude that the lighting fixture seismic supports can withstand se ismic design basis loads.

U.S. Nuclear Regulatory Commission ND-22-0605 Enclosure Page 3 of 3 ITAAC Findings Review In accordance with plant procedures for ITAAC completion , Southern Nuclear Operating Company (SNC) performed a review of all lTAAC findings pertaining to the subject ITAAC and associated corrective actions. This review found that there are no relevant ITAAC findings associated with this ITAAC . The ITAAC completion reviews are documented in the ITAAC Completion Package for ITAAC 2.6.05.03.i (Reference 6) and are available for NRC review.

ITAAC Completion Statement Based on the above information , SNC hereby notifies the NRC that ITAAC 2.6.05.03.i was performed for Vogtle Unit 4 and that the prescribed acceptance criteria are met.

Systems, structures, and components verified as part of this ITAAC are being maintained in their as-designed , ITAAC compliant condition in accordance with approved plant programs and procedures.
