IVICL-EAR P~k ,SCF Licen see Perspective on ITAAC Completion Process NRC Commission Briefing August 30, 2011 Alan Torres SCE&G 1 Topics Requirements for ITAAC Performance Utility's Role ITAAC Completion Process Transition to Operation CIP Task Force Efforts Requirements for ITAAC Performance

• 10 CFR Part 52- ITAAC provide reasonable assurance that the facility "has been constructed and will be operated in conformance with the License."* ITAAC originate from the COL, including those from the referenced DCD, and ESP (if applicable)-There are approximately 900 ITAAC per unit for V.C. Summer 2&3 Requirements for ITAAC Performance The technical work for ITAAC completion performed in accordance with normal worl processes, requirements, and guidance:-10 CFR 50 Appendix B-NRC Regulatory Guides-ASME Code Section III-ANSI, IEEE, AWS, ACI and other Industry Standards-Licensee Programs and Procedures is k Utility's Role The licensee is activities ultimately responsible for all-Self-performance of some ITAAC (Emergency Planning, Physical Security Program)-Provide direct oversight of ITAAC performance by the Reactor Vendor and Constructor (Westinghouse/Shaw Consortium)

The utility will be the primary interface to itate NRC Inspection of ITAAC activities under IMC-2503 I TAAC Completion Process.icensing Construction/Inspection Operation I'j Combin4 J 180 days.pri r to Scheduled puel Looad License COL)ssued Section I 52.103(g)Finding that all ITAAC are met ITAAC Completion Process Inspections, Tests, and Analyses are performed in accordance with normal work processes-Not all ITAAC are safety-related, but all ITAAC are performed under the Licensee's QA program-Extra visibility is provided on ITAAC activities due to their regulatory significance" Identification on project schedules" Highlighted within construction work documents and pre-operational test procedures" Emphasized in procurement technical requirements ITAAC Completion Process ITAAC Closure Notifications prepared in accordance with NEI 08-01 and RG 1.215 Work continues with the CIP Task refine the ITAAC Closure process additional examples 120 Planning to mitigate oo0 the expected "surge"80 in ITAAC Closure 640 Notifications late in 20 construction 0 L ... .Force to and develop T ...... .........§3 0tp -ýqý 1 ,ýq, ro b Ný -tKN ITAAC Completion Process The Staff has proposed new requirements for post-closure ITAAC notifications

-Supplemental ITAAC closure notifications re: ITAAC Maintenance-All ITAAC Complete notification Consistent with NEI 08-01 (July 2010)NEI provided comments on the proposed rule and draft regulatory guide DG-1250 ITAAC Completion Process Licensee's programs will be used to maintain ITAAC (per NEI 08-01)-Problem Identification and Resolution

-Construction/Maintenance

-Configuration Control-Quality Assurance NRC Notification when:-Material error or omission in ITAAC Closure Notification

-Design Change is implemented because the ITAAC acceptance criteria can no longer be met-Licensee activities materially affect the ITAAC Determination Basis Transition to Operation All ITAAC are met. The as-built configuration of the plant is verified to meet the requirements of the COL Commission can make finding under 10 CFR 52.103(g) allowing fuel load and operation Additional clarity/regulatory guidance needed for requirements associated with interim operation under 10 CFR 52.103(c)

CIP Task Force Efforts Preparation of additional example ITAAC Closure Notifications to reduce uncertainty in the closure process Streamlining processes and clarifying expectations to assist with the surge in ITAAC Closure Notifications late in construction Preparations for ITAAC -Vogtle 3&4 Experience Chuck Pierce Southern Nuclear Operating Company Nuclear Development Licensing Manager August 30, 2011 Preparations for ITAAC Closure* Constructive public interactions with NRC (SECY-1 1-0111)-NRC Construction Inspection Program-NRC Region II-Simulated ITAAC Closure and Verification Demonstration sponsored by DOE* ITAAC closure process development and oversight-Contractor interactions and oversight-Ongoing development of process SOUTHERNA COMPANY untS & Nul ar Devlop ea Early Construction Experience

• Five main categories of Lessons Learned 1. Roles/Interfaces:

HQ, Region II CCI, Licensee 2. Information Management Systems (Licensee and NRC)3. Resolve differing interpretations of ITAAC-Ongoing CIP Task Force Discussions

-Update NEI 08-01 with additional guidance when necessary 4. Assuring Sufficient Information in ITAAC Closure Letters 5. Mitigate impact of ITAAC Surge 6 Westinghouse Non-Pit~jprletary esl ots

Lesson -Different expectations on closure letter content for ITAAC without a similar NEI 08-01 example resulted in re-submittal of closure letters* Goal -Provide additional confidence and certainty in the content of ITAAC closure letters" Activity -"Expanded ITAAC Closure Notification Project"-Westinghouse/NEI will prepare approximately 30 additional example letters-More than 80% of AP1000 ITAAC will be represented

All Rights Reserved.Lesson Learned-ITAAC Surge Mitigation tOO....* Lesson -By their nature, ITAAC require verification of the as-built plant, and therefore most occur late in construction" Goal -Mitigate the challenges associated with this surge" Factors Identified During Demo Project-Work frequently occurs well in advance of Closure Letter submittal (Example:

ASME ITAAC)-Many of the latest ITAAC are pre-operation tests, which involve a well understood process with significant NRC Inspector involvement

• Additional Activities In-Progress

-Detailed planning for each ITAAC-Focus on process efficiency
