U.S. Nuclear Regulatory Commission ND-20-0976 Enclosure Page 2 of 3 ITAAC Statement Design Commitment:

3.c) The equipment hatch hoist is single failure proof.

Inspections. Tests. Analyses:

ii) Testing of the equipment hatch hoist is performed.

Acceptance Criteria:

ii) The equipment hatch hoist holding mechanism shall stop and hold the hatch.

ITAAC Determination Basis Multiple ITAAC were performed to demonstrate the equipment hatch hoist is single failure proof.

For this ITAAC, a test was performed in accordance with Site Acceptance Test SV3-MH40-VTP-002 to demonstrate that the equipment hatch hoist holding mechanism stopped and held the hatch.

Testing was performed in accordance with Domestic AP1000 Hatch Hoist Site Acceptance Test (SAT) SV3-MH40-VTP-002(Reference 1) which required that the equipment hatch hoist holding mechanism stops and holds the hatch. The equipment hatch hoist was attached to the equipment hatch, along with additional test weights to achieve 100% of the hoist rated load, during the load test portion of the SAT. The hatch and weights were raised by the hoist higher than one foot, stopped, and verified to hold the hatch for at least one minute and not drift down after stopping.

The hatch and weights were lowered, stopped, and held again for at least two minutes and verified to hold the hatch and not drift down after stopping. The completed SAT is contained in the site record for Work Order SV3-MHS-T0W-1068326 (Reference 2). The completed SAT performance data was compared to the ITAAC Acceptance Criteria in ITAAC Technical Report SV3-MHS-ITR-800350 (Reference 3).

The completed SAT demonstrated that the equipment hatch hoist holding mechanism stopped and held the hatch. The ITAAC Technical Report (Reference 3) and ITAAC Completion Package (Reference 4) are available for NRC inspection.

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 review is documented in the ITAAC Completion Package for ITAAC 2.3.05.03c.ii (Reference 4) and is available for NRC review.

ITAAC Completion Statement Based on the above information, SNC hereby notifies the NRC that ITAAC 2.3.05.03c.ii was performed for VEGP Unit 3 and that the prescribed acceptance criteria are met.
