U.S. Nuclear Regulatory Commission ND-13-0257 Enclosure Page 2 of 3 ITAAC Statement Desion Commitment 8.a) The CVS provides makeup water to the RCS.
Insoections.Iests. Analvsis ii) Inspection of the boric acid storage tank volume will be performed.
Acceptance Criteria ii) The volume in the boric acid storage tank is at least 70,000 gallons between the tank suction point and the tank overflow.
ITAAC Determination Basis Multiple ITAAC are performed to demonstrate that the Chemical and Volume Control System (CVS) provides makeup water to the Reactor Coolant System (RCS). This ITAAC performs inspections to verify volumes in Unit 3 and Unit 4 boric acid storage tanks(BAST)(SV3-CVS-MT-01 and SV4-CVS-MT-01)are at least 70,000 gallons between the tank suction point and the tank overflow (i.e., usable volume).
Inspections of each BAST were performed by the vendor to demonstrate the Unit 3 and Unit 4 BAST usable volume. The BAST does not have an overflow line; however, an atmospheric vent line is installed on the top of the tank dome. As-built measurements of the individual tanks' outer circumference and distance from the bottom of each outlet pipe (suction point) to the top of each tanks' cylindrical shell were taken and recorded. These measurements were used to determine each tanks' volume considering the shell thickness and unavailable volume due to tank internals.
Each BAST volume was documented in the Unit 3 and Unit 4 Vendor Volume Calculations (Reference 1 and 2, respectively) which verify the boric acid storage tank volumes are 80,349 gallons each for both Unit 3 and Unit 4 and meets the ITAAC acceptance criteria.
Reference 1 and 2 are available for NRC inspection as part of the Unit 3 and Unit 4 ITAAC completion packages(Reference 3 and 4, respectively).
ITAAC Finding Review In accordance with plant procedures for ITAAC completion. Southern Nuclear Operating Company(SNC) performed a review of all ITAAC 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 Packages for ITAAC 2.3.02.08a.ii (Reference 3 and 4)and are available for NRC review.

U.S. Nuclear Regulatory Commission ND-19-0257 Enclosure Page 3 of 3 ITAAC Completion Statement Based on the above information, SNC hereby notifies the NRG that ITAAC 2.3.02.08a.ii was performed for VEGP Unit 3 and Unit 4 and that the prescribed acceptance criteria were 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.
