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

• peration of its Members' nuclear

power units.

Introduction to FROG April 2012 - p. 7

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. 8

Organization

Network of Experience

►A worldwide network of experience mixing plant

• peration and NSSS designer

Introduction to FROG April 2012 - p. 15

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

• perating experience (~ 80 plants) within a rather

small group of utilities ►Work performed within FROG contribute to improving plant safety and efficiency
