REPORT DETAILS
- 1. CONSTRUCTION REACTOR SAFETY Cornerstones: Design/Engineering, Procurement/Fabrication, Construction/Installation, Inspection/Testing IMC 2503, Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC) - Related Work Inspections 1A01 (Unit 3) ITAAC Number C.2.6.09.05a (664) / Family 17A (Unit 4) ITAAC Number C.2.6.09.05a (664) / Family 17A
- a. Inspection Scope The inspectors performed a direct inspection of construction activities associated with ITAAC Number C.2.6.09.05a (664). The inspectors used the following NRC Inspection Procedures (IPs)/sections to perform this inspection:
- 65001.17-02.08-Vehicle Control Measures The inspectors performed an inspection to verify active vehicle barriers at two locations were constructed, installed and secured in place in accordance with the design specifications to satisfy the ITAAC requirement, Title10 of the Code of Federal Regulations (10 CFR) 73.55(e)(3), and 10 CFR 73.55(e)(10).
The inspectors reviewed the design specification for the active vehicle barrier system and associated drawings to identify the requirements for installation of the active vehicle barriers. During this inspection period, the inspectors observed the physical installation and reviewed installation records for the barriers at the primary vehicle access portal on the south side of Unit 3 and reviewed installation records for the barriers at the warehouse on the north side of Unit 3.
At the north primary vehicle access portal, the inspectors performed in-field measurements of installed reinforcing steel prior to concrete placement to verify it was the correct size; met spacing requirements; had minimum concrete clear cover; lap splices met the minimum length; and the foundation had the required depth and thickness in accordance with design drawings, specifications SV0-SES-Z0-800001 and SV0-CR01-Z0-002, and American Concrete Institute (ACI) 318-08. The inspectors independently assessed the placement area prior to concrete placement to determine whether it was secure, leak tight, and free from debris or excess water as required by SV0-CR01-Z0-002 and ACI 318-08. The inspectors reviewed the concrete placement plan included in the work package to determine whether pre-placement planning had been completed, including considerations for weather, mass concrete, and unexpected events.

At the south primary vehicle access portal, the inspectors observed concrete placement activities for both wedge gates to determine whether approved work instructions, procedures, and specifications were available in the work area and were followed throughout the concrete placement as required by the licensee's quality assurance program. The inspectors observed concrete placement activities to verify placement drop distances did not exceed requirements and determine whether consolidation using vibrators was adequately performed to prevent mix segregation as specified in SV0-CR01-Z0-002, ACI 318-08, and ACI 309R-05. The inspectors observed the concrete truck in use during the placements to verify the time interval between mixing and placing was less than 90 minutes in accordance with SV0-CR01-Z0-002 and ASTM C94-18. The inspectors observed the concrete in the concrete trucks and at the point of placement to verify it was uniformly mixed in accordance with SV0-CR01-Z0-002, ACI 318-08, and American Society for Testing and Materials (ASTM) C94-18. The inspectors evaluated the batch tickets to determine whether each batch ticket was reviewed for transport time and truck rotations, verification of proper mix, and placement location in accordance with SV0-CR01-Z0-002, ACI 318-08, and ASTM C94-18.
For both vehicle access portals, the inspectors reviewed the completed batch tickets and test reports, including the concrete cylinder strength testing, to verify the records were complete and contained the required information in accordance with SV0-SES-Z0-800001, SV0-CR01-Z0-002, ACI 318-08, and the applicable ASTM standards.
Additionally, the inspectors reviewed the concrete cylinder break test results to verify the concrete tested met the strength requirements for the specified concrete mix in accordance with specification SV0-SES-Z0-800001.
For both vehicle access portals, the inspectors performed independent inspection and measurements of the as-built concrete, including finishes and dimensions, to determine whether the as-built configurations were in accordance with SV0-SES-Z0-800001, SV0-CR01-Z0-002, ACI 318-08, and the work packages. The inspectors reviewed the completed work packages for deviations or nonconformances to verify the licensee's corrective actions and disposition of any deviations and nonconformances were in accordance with the licensee's quality assurance and corrective action programs.
- b. Findings No findings were identified.
1A02 (Unit 3) ITAAC Number C.2.6.09.08a (668) / Family 17A
- a. Inspection Scope The inspectors performed a direct inspection of construction activities associated with ITAAC Number C.2.6.09.08a (668). The inspectors used the following NRC IPs/sections to perform this inspection:
- 65001.17-02.02-Vital Areas/Vital Area Barriers 4
The inspectors performed an inspection to determine if the openings in Vogtle Unit 3 vital area (VA) barriers for heating, ventilation, and cooling (HVAC) system vents were secured to prevent exploitation of the openings to satisfy the ITAAC requirement and 10 CFR 73.55(e)(4).
The inspectors reviewed the design specifications and associated drawings to identify designated HVAC system openings through VA barriers and the way they will be secured and monitored. The inspectors examined the physical installation of the barriers at nine HVAC system openings (SV3-VTS-AS-16, SV3-VTS-AS-17, SV3-VTS-AS-18, SV3-VXS-AS-06, SV3-VXS-AS-08, SV3-VXS-AS-09, SV3-VBS-AS-03, SV3-VBS-AS-22, and SV3-VBS-AS-23) to the VA during this inspection period. The inspectors performed direct observation inspections of the openings to determine if they were secured in a manner that would delay or prevent exploitation. Specifically, the inspectors directly inspected the barrier, locking mechanisms, welds, bolts, etc.,
associated with the openings.
In addition, the inspectors reviewed the design specification and associated drawing for the HVAC system duct enclosure plate at wall MK W129 in the annex building and the way it was secured. The inspectors examined the physical installation of the enclosure plate to verify, through direct observation and measurements, if the enclosure plate met the design details and was securely mounted to the wall in a manner that delays or prevents exploitation.
- b. Findings No findings were identified.
- 4. OTHER INSPECTION RESULTS 4OA6 Meetings, Including Exit
.1 Exit Meeting.
On October 16, 2019, the inspectors presented the inspection results to Mr. M. Meier, SNC Vice President of Regulatory Affairs, and other licensee and contractor staff members. Proprietary information was reviewed during the inspection period but was not included in the inspection report.
