O Attachment to AECM-80/73 STATUS REPORT, PRD-80/05 I. Description of Deficiency Cable damage was sustained during the cable pulling process. Two Bechtel Non-Conformance Reports (NCR) have documented this condition noted in two cases of cable damage. In both cases, the damaged cables are associated with Control Room HVAC system (Z51). The initial findings have incicated that the cables were damaged by the poly-propylene pulling rope. The nature of damage ranges from jacket chafing to insulation cut through to the conductor. The condition was noted when all cables were removed from their common conduit to allow the pulling of an additional cable in that conduit.

II. Safety Implication The deficiency, limited to the damaged items referenced above, would not have adversely affected the safety of plant operations. A state-ment on the overall safety implications of this deficiency cannot be made until the extent of the problem has been determined.

III. Corrective Actions The damaged cables identified in the above mentioned Bechtel NCR's have been replaced. This matter is documented and filed under Bechtel Management Corrective Action Report (MCAR)-CGNS No. 64. This file is available for your review at the construction site.

The investigation as to the extent of this problem and corrective actions to prevent recurrence is in progress.
