Subject:
Crystal River Containment Wall Concrete Delamination For Internal Information only Mark:
Last week I had a chance to observe the CTL company performed Sound Detecting system for the containment wall in the uncracked area outside the wall opening bay. They did not detect any cracks in the other bays so far.
Two days ago, I went to observe the CTL performed the detection in the wall opening bay between Buttresses 3 and 4. I observe they detected the cracks in this bay. Based on the discussion with them, the whole bay between the buttresses 3 and 4 and from the top of the equipment hatch up to 10 ft. (one panel) below the dome has the delamination. The detection for this bay is almost completed. They only completed the detection about one third of other bays.
