NOTE: The discussion on each topic will start with a 10' introduction by the General Reviewers (G.Rs.), followed by comments by the audience. The introduction will include an overview of code provisions, relevant contributions of this workshop, as well as the G.R.'s recommendations. The main conclusions from each discussion session will be summarized by the G.Rs. in a separate chapter of the final report that will be prepared (after the workshop), as an account of the ETC-12 activities.
