FIRST INTERIM REPORT i
Description of Deficiency General Specification G-32 Appendix D (implemented onsite by BNP-QCP-2.8) requires that in large holes or chipped out areas where grouted anchors are used, the chipped out area shall extend at least three nominal bolt diameters for individual and six nominal bolt diameters for multiple anchors beyond the end of the anchor. These chipped areas should then be refilled with concrete for support. Seismic pipe supports have been installed with anchor bolts such that the chipped areas have possibly been chipped only to the bottom of the anchor.
Interim Progress TVA's Division of Engineering Design (EN DES) is evaluating the possibility of using the anchors in their present condition. We will provide more information in our next report.
