Exhibit Title:

NER038 Gocevski, V., "Pathologies/Degradation Mechanisms Experienced by Hydro-Quebec During the Evaluation of Gentilly-2 NPP," Report

Submitted to ASCET, (June 2015)

"I would like to summarize in few words our discussion. The participants' reports should be submitted by April 15 th and they should contain 9 Chapters: 1) introduction, 2) material aspects and lab. Material testing, 3) Material modeling, 4) Lab. structural components testing - destructive testing, 5) Structural modeling, 6) Non-destructive testing and in-situ condition assessment, 7) Structural acceptance criteria for structures with pathologies/degradation mechanisms, 8) structural repair and 9) Conclusions and recommendations for future work (conclusions and recommendations are related to each report)".
