U.S. Nuclear Regulatory Commission ND-19-1254 Enclosure Page 2 of 3 ITAAC Statement Design Commitment 3.b) The equipment hatch hoist is single failure proof.

Inspections.Tests. Analysis i) Validation of double design factors is provided for hooks where used as load bearing components. Validation of redundant factors is provided for load bearing components such as:

• Hoisting ropes

• Sheaves

• Equalizer assembly

• Holding brakes Acceptance Criteria i) A report exists and concludes that the equipment hatch hoist is single failure proof. A certificate of conformance from the vendor exists and concludes that the equipment hatch hoist is single failure proof.

ITAAC Determination Basis Multiple ITAAC are performed to demonstrate that the equipment hatch hoist is single failure proof. The subject ITAAC requires that validation of double design factors is provided for hooks where used as load bearing components, and that validation of redundant factors is provided for load bearing components such as hoisting ropes, sheaves, equalizer assembly and holding brakes.

The equipment hatch hoist is a single failure proof design which conforms to the guidelines of NUREG-0554 "Single-Failure-Proof Cranes for Nuclear Power Plants"(Reference 1),

supplemented by American Society of Mechanical Engineers(ASME) NOG-1-1998,"Rules for Construction of Overhead and Gantry Cranes(Top Running Bridge, Multiple Girder)"

(Reference 2). Single failure proof design is described in NUREG-0554 as "a single failure will not result in the loss of the capability of the system to safely retain the load." The requirements to follow NUREG-0554,supplemented by ASME NOG-1-1998,for the design of the equipment hatch hoist were imposed in the design specification (Reference 3).

The equipment hatch hoist single failure proof report (Reference 4) exists and concluded that the equipment hatch hoist is single failure proof. Additionally, a certificate of conformance (Reference 5)from the equipment hatch hoist vendor (manufacturer) exists and concluded that the equipment hatch hoist is single failure proof.

U.S. Nuclear Regulatory Commission ND-19-1254 Enclosure Page 3 of 3 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.i (Reference 6) 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.i was performed for VEGP 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.
