On ilanuary '6,1988, TU Electric's report logged TXX-88025 provided notification of a reportable deficiency involving the 6.9kV/480V transformer bus bar clearance.

Supporting documentation for Unit 1 is available for NRC review at' the CPSES site. Unit 2 corrective actions will be 7 completed prior to Unit 2 fuel load.
Sincerely,
