In addition to the "significant deviations" discovered during Bulletin 79-14 inspections, five deviations which were discovered during Bulletin 79-02 inspections and evaluated asBulletin 79-14 problems, also affected system function. These are tabulated below.
Unit System No. of Significant Deviations 2

An NCR was recently written against the BBCCW system, all units, due to an inconsistency between support spacing and the seismic loading of those supports. A representative line segment was rigorously analyzed and was shown to be still qualified. The balance of the RBCCW will be cvaluated and rigorously analyzed, as required, as the 79-14 irspection information is received.
