O DUKE POWER COMPANY MCGUIRE NUCLEAR STATION UNITS 1 & 2 Report Number: SD-369-370/80-02 Report Date: March 27, 1980 Facility: McGuire Nuclear Station - Units 1 and 2 Description of Deficiency:
During review of environmental qualification documentation for safety-related electrical equipment, it was determined that the steam generator narrow-range level transmitter cables did not meet the environmental qualification require-ments. These cables had been certified for 30 days of post-accident condi-tions instead of the required 120 days. Sixteen cables in Unit No. I contain-ment are involved. The cables for Unit No. 2 have not been installed.
Analysis of Safety Implication:
The cable crtification does not provide adequate assurance that the cables would function properly for the required 120 days in a post-accident environ-ment.
Corrective Action:
The sixteen affected cables in Unit No. I will be replaced before fuel loading with cables which meet the environmental qualification requirements. These new cables will also be installed in Unit No. 2 during the normal construction process. This corrective action is being taken because the time required to perform specific environmental confirmation tests on the existing cables is not compatible wich the construction and licensing schedu!.e.
