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 is performed in accordance with normal worlk 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

Utility's Role The licensee is ultimately responsible for all activities

- 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

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

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

Lessons Learned tooo-

Project was a very useful learning experience, identifying several opportunities for improvement

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

Lesson Learned-Closure Letter Information e ...

" 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

- Letters reviewed with NRC staff at CIP Task Force Public Meetings

- Letters added to NEI 08-01 after mutual NRC/NEI concurrence 7 7 Wýstlinghouse Nofl-Prtprletary C $ws finghouse

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

- Leverage CIP Task Force work to reduce process uncertainty 9
