Tuesday, November 24, 2009 8:23 AM Rezai, Ali IChan, Terence; Franke, Mark Response to NDT Question from NRR.pdf; 059169_NDT Qualification Letter_1 1-11-09.pdf;,)
-/ Request 1 0.docx; Request 11.docx; Request 16.docx Ali; I understand that you have been assigned to review the NDT activities at Crystal River.
To facilitate your review, attached are the responses provided by Crystal River staff to your questions on the NDT techniques used for identification of the de-lamination in the CR containment. I included responses I received to some of the related questions asked by the SIT team and on the personnel qualification issue. I have resumes/individual qualification information (not attached) for each NDT technician that was on site. Let me know if you need this info.
Note that there is no industry standard on how to qualify these NDT techniques. The NDT results were subsequently confirmed by core bores in the containment surface.
If needed, we can set up a conference call next week to resolve any questions you may have. I will out of the office beginning today at 11:00am and will return on Monday, Nov. 30.
