April 11, 2018 MEMORANDUM TO: Terry W. Jackson, Chief Quality Assurance Vendor Inspection Branch-1 Division of Construction Inspection and Operational Programs Office of New Reactors FROM: Yamir Diaz-Castillo, Inspection Team Leader /RA/
Quality Assurance Vendor Inspection Branch-1 Division of Construction Inspection and Operational Programs Office of New Reactors
SUBJECT:
CLOSURE OF ITAAC RELATED-FINDING FOR SPECIALTY MAINTENANCE AND CONSTRUCTION INC. INSPECTION REPORT NO. 99901439/2015-201 The purpose of this memorandum is to document the U.S. Nuclear Regulatory Commission (NRC) staffs closure of the Notice of Nonconformance (NON) documented in Specialty Maintenance and Construction Inc.s (here after referred to as SMCI) Inspection Report (IR)
No. 99901439/2015-201, dated July 24, 2015 (Agencywide Document Access and Management System (ADAMS) Accession No. ML15175A446). The NRC staff chose to issue this memorandum due to SMCI going out of business in December 2016.
On June 8-12, 2015, the NRC staff completed an inspection at the SMCI facility in Lakeland, FL.
The purpose of this technically-focused, limited scope reactive inspection was to evaluate SMCIs implementation of quality activities associated with the fabrication of the embed plates for the CA-01 (steam generator and refueling canal modules) and CA-02 (independent wall structure connecting CA-1 and CA-03 (in-containment refueling water storage tank module))
modules for the Westinghouse Electric Companys (WEC) AP1000 reactor design for the Vogtle Electric Generating Plant, Units 3 and 4, currently under construction.
In IR No. 99901439/2015-201, the NRC staff issued NON 99901439/2015-201-01 and NON 99901439/2015-201-02, which the NRC staff determined were material to the acceptance criteria of inspections, tests, analyses, and acceptance criteria (ITAAC) No. 3.3.00.02a.i.a (760) from Revision 19 of the certified AP1000 Design Control Document.
NON 99901439/2015-201-01 documents a finding against Criterion III, Design Control, and Criterion IX, Control of Special Processes, of Appendix B, Quality Assurance Program Criteria for Nuclear Power Plants and Fuel Processing Plants, to Title to 10 of the Code of Federal Regulations (10 CFR) Part 50, Domestic Licensing of Production and Utilization Facilities, for SMCIs failure to transfer all the pertinent design requirements into the applicable instructions and failure to inspect welds in accordance with the applicable travelers and design specification
T. Jackson drawings. NON 99901439/2015-201-02 documents a finding against Criterion IX of Appendix B to 10 CFR Part 50 for SMCIs failure to control welding consumable filler metal in accordance with applicable procedures and criteria.
In a letter dated August 18, 2015 (ADAMS Accession No. ML15239A703), SMCI described their corrective actions to address the issues identified in NON 99901439/2015-201-01 and NON 99901439/2015-201-02. In letters dated September 17, 2015, (ADAMS Accession No. ML15258A654), and January 8, 2016 (ADAMS Accession No. ML16007A704), the NRC staff issued a request for information (RFI) from SMCI to provide clarification related to the information provided. In letters dated November 2, 2015 (ADAMS Accession No. ML15313A122), December 17, 2015 (ADAMS No. Accession ML15356A128), and January 27, 2016 (ADAMS Accession No. ML16029A481), SMCI provided additional information to address the NRCs RFI.
The NRC staff reviewed SMCIs responses to the RFI that support the corrective actions taken to address the issues identified in NON 99901439/2015-201-01 and NON 99901439/2015-201-
- 02. Based on this review, the NRC staff determined the corrective actions taken by SMCI are adequate to address the identified nonconformances. NON 99901439/2015-201-01 and NON 99901439/2015-201-02 are closed and no additional inspection follow-up is required to verify completion/adequacy of the corrective actions.

ML18100A857 NRO-002 OFFICE NRO/DCIP NRO/DCIP NAME YDiaz-Castillo TJackson DATE 04/10/18 04/11/18 Summary of NRC Inspection of Specialty Maintenance and Construction Inc. Affecting ITAAC
- 1. AFFECTED INSPECTIONS, TESTS, ANALYSES, AND ACCEPTANCE CRITERIA The U.S. Nuclear Regulatory Commission (NRC) inspectors identified the following inspection, test, analysis, and acceptance criteria (ITAAC) related to components being fabricated by Specialty Maintenance and Construction Inc. facility (here after referred to as SMCI). For the ITAAC listed below, the NRC staff reviewed SMCIs corrective actions in response to Notice of Nonconformance (NON) 99901439/2015-201-01 and NON 99901439/2015-201-02. The ITAACs design commitment referenced below are for future use by the NRC staff during the ITAAC closure process; the listing of these ITAAC design commitments does not constitute that they have been met and closed. The NRC staff identified two findings associated with the ITAAC identified below.
Source Document ITAAC Index No. ITAAC Acceptance Criteria i.a) A report exists which reconciles deviations during construction and concludes that the as-built Appendix C from containment internal structures, the Combined including the critical sections, License for Vogtle No. 760 3.3.00.02a.i.a conform to the approved design and Electric Generating will withstand the design basis loads Plant Units 3 and 4 specified in the Design Description without loss of structural integrity or the safety-related functions.
- 2. FINDINGS AND OBSERVATIONS Based on review of the additional information, the NRC staff has determined that the corrective actions taken by SMCI in response to NON 99901439/2015-201-01 and NON 99901439/2015-201-02 are adequate to address the identified nonconformances.
