U.S. Nuclear Regulatory Commission Document Control Desk Washington, DC 20555-0001 Southern Nuclear Operating Company Vogtle Electric Generating Plant Unit 3 and Unit 4 Notice of Uncompleted ITAAC 225-davs Prior to Initial Fuel Load Item 2.2.01.08 [Index Number 1091 Ladies and Gentlemen:
Pursuant to 10 CFR 52.99(c)(3), Southern Nuclear Operating Company hereby notifies the NRC that as of January 16, 2018, Vogtle Electric Generating Plant (VEGP) Unit 3 and Unit 4 Uncompleted Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC) Item 2.2.01.08 [Index Number 109] has not been completed greater than 225-days prior to initial fuel load. The Enclosure describes the plan for completing this ITAAC. Southern Nuclear Operating Company will, at a later date, provide additional notifications for ITAAC that have not been completed 225-days prior to initial fuel load.
Southern Nuclear Operating Company (SNC) previously submitted, via letter ND-16-2179
[ML16314A034], a Unit 3 Notice of Uncompleted ITAAC 225-days Prior to Initial Fuel Load for Item 2.2.01.08 [Index Number 109]. This resubmittal supersedes the previous Unit 3 notice in its entirety.
This notification is informed by the guidance described in NEI 08-01, Industry Guideline for the ITAAC Closure Process Under 10 CFR Part 52, which was endorsed by the NRC in Regulatory Guide 1.215. In accordance with NEI 08-01, this notification includes ITAAC for which required inspections, tests, or analyses have not been performed or have been only partially completed. All ITAAC will be fully completed and all Section 52.99(c)(1) ITAAC Closure Notifications will be submitted to NRC to support the Commission finding that all acceptance criteria are met prior to plant operation, as required by 10 CFR 52.103(g).
This letter contains no new NRC regulatory commitments.

- 8. Containment electrical penetration assemblies are protected against currents that are greater than the continuous ratings.
Insoections/Tests/Analvses An analysis for the as-built containment electrical penetration assemblies will be performed to demonstrate (1) that the maximum current of the circuits does not exceed the continuous rating of the containment electrical penetration assembly, or (2) that the circuits have redundant protection devices in series and that the redundant current protection devices are coordinated with the containment electrical penetration assembly's rated short circuit thermal capacity data and prevent current from exceeding the continuous current rating ofthe containment electrical penetration assembly.
Acceptance Criteria Analysis exists for the as-built containment electrical penetration assemblies and concludes that the penetrations are protected against currents which are greater than their continuous ratings.
iTAAC Completion Description An analysis for the as-built containment electrical penetration assemblies is performed to demonstrate (1) that the maximum current of the circuits does not exceed the continuous rating of the containment electrical penetration assembly, or (2) that the circuits have redundant protection devices in series and that the redundant current protection devices are coordinated with the containment electrical penetration assembly's rated short circuit thermal capacity data and prevent current from exceeding the continuous current rating of the containment electrical penetration assembly.
Most low voltage instrumentation and communication circuits are self-limiting inthat circuit resistance limits the fault current to a level that does not damage the penetration. The energy levels in the instrumentation and communication systems are such that damage cannot occur to the containment penetration. Forcircuits that are not self-limiting, an analysis is performed to verify the as-built containment electrical penetration assemblies are protected against currents that are greaterthan the manufacturer's continuous ratings. The analysis demonstrates that the maximum current of the circuits does not exceed the continuous rating of the containment electrical penetration assembly, or in circuits with high short circuit current, that each circuit has redundant protection devices in series, and that the redundant current protection devices are coordinated with the containment electrical penetration assembly rated short circuit thermal capacity curves, and the fault current does not exceed the penetration assembly rated short circuit thermal capacity curve in the continuous current time range. Each circuit that requires redundant protective devices is identified in the applicable protection coordination calculations.
The containment electrical penetration assemblies analyzed are listed in Attachment A. Spare penetrations or penetrations containing low voltage instrumentation and communication circuits which are excluded from the analysis are noted in Attachment A.
U.S. Nuclear Regulatory Commission ND-18-0016 Enclosure Page 3 of 4 The electrical penetrations are designed in accordance with IEEE Standard 317 (Reference 1).
Qualification testing of the electrical penetrations is performed in accordance with IEEE Standard 317 and IEEE Standard 323 (Reference 2). The analysis of the as-built containment electrical penetration assemblies is performed in accordance with section 5.4 of IEEE Standard 741 (Reference 3). Analysis of Class 1E circuits is documented in APP-IDS-EOC-014, (Reference 4). Analysis of Non-Class 1E circuits is documented in APP-ECS-EOC-016, (Reference 5). The analysis results are summarized in APP-CNS-ZOR-001, (Reference 6).
The analysis results exist for the as-built containment electrical penetration assemblies and conclude that the penetrations are protected against fault currents which are greater than their continuous current ratings.
The Electrical Penetration Assemblies (EPA) Protection Analysis is availabie for NRC inspection as part of the ITAAC Completion Package (Reference 7).
List of ITAAC Findings In accordance with plant procedures for ITAAC completion, Southern Nuclear Operating Company (SNC) performed a review of all findings pertaining to the subject ITMC and associated corrective actions. This reviewfound there are no relevant ITAAC findings associated with this ITAAC.
