Background on status of AP1000 design review and licenses
New Reactor Designs/applications in the USA
Quick construction status – Vogtle and Summer AP1000s
Part 52 and lessons learned from a regulatory perspective
Background

•
Combined license – NRC authorization to construct and operate a nuclear power plant
in accordance with applicable laws, regulations, and conditions
Latest version of Westinghouse’s AP1000 standard design certified in December 2011
SNC, et al, received combined licenses for Vogtle Units 3 and 4 on February 10, 2012
SCE&G, et al, received combined licenses for Summer Units 2 and 3 on March 30, 2012
First Nuclear Concrete (FNC) for Summer Unit 2 poured 9 – 11 March 2013
FNC for Vogtle Unit 3 poured 12 – 14 March 2013
4 AP1000s under construction in China (Sanmen and Haiyang sites commenced in
2008) – cooperation with China bilaterally and multilaterally
AP1000 design reviewed/under review in Canada, China, and the U.K. (MDEP)

Certification
• Licensing decisions finalized before major construction begins
• Inspections w/ITAAC (Inspections, Tests, Analyses, and Acceptance Criteria) to verify construction
• Limited work may be authorized before COL issuance

Lessons Learned in COL Reviews
First implementation of NRC’s 10 CFR Part 52 processes to issue COLs
•
•
Bipartisan Policy Center Report (April 6, 2010)
• Thorough and timely evaluation of license applications…however, there were
expected problems in navigating the new processes
• The Commission should ensure the lessons learned are rigorously applied to
make the processing of subsequent applications more efficient
NRC’s Lessons Learned Review Report – April 213
• High quality applications with sufficient detail
• Timely development and maintenance of regulatory guidance
• Strong design standardization
• Early identification and timely resolution of complex issues
• Improve system of requests for additional information
• Concurrent reviews of design certifications and combined license applications
• Update to regulations incorporating lessons learned
6
Current Licensing Basis
Definition of Licensing Basis (10 CFR 54.3)
• Obligations (Regulations, License Conditions, Technical
Specifications, Environmental Protection Plan,
and ITAAC)
• Mandated Licensing Basis Documents (FSAR, QA, EP,
Security Plan, etc.)
Vogtle/Summer-FSAR:
• Summer — COL FSAR +Plant Specific DCD
• Vogtle — ESP SSAR + COL FSAR + Plant Specific DCD

Experience post-COL Issuance
First implementation of Part 52 processes (licensing basis maintenance)
• License amendment (LARs), and exemptions, and ASME code relief requests
• LARs are expected as design evolves and due to in-situ conditions
• Design changes to rebar (shear reinforcement details)
• Turbine building bracing
• Additional electrical penetration assemblies in the containment
• Inconsistencies between Tier 1 and Tier 2
• Other
• Preliminary Amendment Request (PAR) Process
• Codified in license as an option for the licensee (following ISG-25)
• Flexibility in making physical changes while licensing basis change is udner
review
• Tied to an LAR
• Obligation to construct in accordance with the licensing basis
• NRO is performing a self assessment of the experience during the first year of
licensing Part 52 plants (with input from licensees, vendors, public, staff)
9
Summary
•First implementation of Part 52 regulations to issue COLs and for post-licensing
processes
•Vogtle and Summer licenses issued and construction ongoing
•Experience gained in licensing pre and post COL isance
•A learning experience for regulator and licensee
•Improvements can be made
•Assessments to inform improvements
•Philosophy of Part 52 – Standardization
•Importance of maintaining current licensing basis
•Managing changes appropriately
•Proper change processes
•Safety benefits
•ITAAC completion
•Safe operation
