The FROG Worldwide QNPC Introduction to FROG April 2012 - p. 5

Mission ▌ The FROG mission is dedicated to building strong and efficient teaming for mutual co-operation, assistance, and sharing of its Members' experience and expertise, to support the safe, reliable, and cost-effective operation of its Members' nuclear power units. Introduction to FROG April 2012 - p. 6

Objectives ► Constitute a forum for utilities and also designer to exchange on all aspects of operating experience ► Provide a mechanism for identifying and resolving generic issues through effective channels established between utilities, designer, and other organizations ► Provide cost/delay effective resolution of generic problems ► Allow any member to participate to development programs ► Set an organization for exchanging operating experience with similar Owners Groups Introduction to FROG April 2012 - p. 7

Organization ► Senior Executive Council � Set long term plans/objectives � Approve Charter amendment ► Steering Committee � Set short/mid term plans/objectives � Provide direction and oversight of all FROG activities � Approve budget and program funding � Chairman & Vice-Chairman elected for 2-year term ► Technical Committees, Working Groups, Correspondent Networks � Implement decisions and policies adopted by SC ► AREVA � Provide administrative and technical support Introduction to FROG April 2012 - p. 8

FROG Activities ► Meetings Operating Steam Outage Material Diesel Steering RIA Steering Procedures Generator Optimization Ageing WG WG Committee WG Committee WG TC WG ► Joint Programs � More than 30 programs completed or in progress � Examples • R&D: e.g. 600/690 Alloys Primary Water Stress Corrosion Cracking • Benchmarking studies and improvement suggestions: e.g. Operating Procedures • Degradation modes analyses: e.g. RV Internals, SG ► Correspondent Networks � Ageing Network � Spare Part Network Introduction to FROG April 2012 - p. 9

Steering Committee Meetings Operating Steam Outage Material Diesel Steering RIA Steering Procedures Generator Optimization Ageing WG WG Committee WG Committee WG TC WG ► Twice a year ► Attendance � Utility operation managers or representatives (SC Members) � FROG Secretary � AREVA Management representatives (including Engineering, Services, Fuel, I&C) � Utilities/AREVA specific speakers depending on agenda ► Agenda � Operating experience: performance & main events � Specific subjects analyzed trough Members and/or AREVA presentation, e.g. Obsolescence Management, Dose Reduction, Contractor Management in Maintenance, Spare Part Management, Feedback Process, Core Thermal Power Measurement, Human Performance Introduction to FROG April 2012 - p. 10

Working Groups Meetings Operating Steam Outage Material Diesel Steering RIA Steering Procedures Generator Optimization Ageing WG WG Committee WG Committee WG TC WG ► Currently 5 Working Groups + 1 Technical Committee ► Each group meet once a year ► Attendance � Utility/plant specialists in the WG domain � AREVA experts including US and German representatives ► Agenda � Operating experience in the WG specific domain � Specific technical issues � Discussions of potential & current Joint Programs ► Additionally, occasional Workshops: Spare Parts, Ageing, etc Introduction to FROG April 2012 - p. 11

FROG Technical Publications ► Distribution to FROG Members ► Information Notices, Significant Event Reports, Material Event Reports � Summarize an event that • occurred in a FROG Member or non-FROG Member unit • can be considered as important for FROG Members � Present event cause analysis, potential impact for FROG Member units, AREVA position and/or recommendation, as available ► Designer Newsletters � State AREVA’s position as NSSS designer on a specific topic of general interest to FROG Members ► Technical Program Reports ► FROG Performance Indicators Reports Introduction to FROG April 2012 - p. 12

Network of Experience ► A worldwide network of experience mixing plant operation and NSSS designer Introduction to FROG April 2012 - p. 14

Conclusion ► FROG Owners Group is an effective forum for building networks between utilities and involving NSSS designer ► Each FROG Member benefits from sharing a large operating experience (~ 80 plants) within a rather small group of utilities ► Work performed within FROG contribute to improving plant safety and efficiency Introduction to FROG April 2012 - p. 15
