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

Network of Experience

►A worldwide network of experience mixing plant operation and NSSS designer

Introduction to FROG September 2010 - 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 operating experience (~ 80 plants) within a rather small group of utilities

►Work performed within FROG contribute to improving plant safety and efficiency
