Subject:
Crystal River Unit 3 Docket No. 50-302 Operating License No. DPR-72 Adequacy of Station Electric Distribution System Voltage
Dear Mr. Stolz:
The attached two tables of voltage values are submitted to further demonstrate adequacy of the Crystal River Unit 3 Electrical Distribution System.
The information was requested in telephone conversation with your Mr. Syd Miner when he reviewed our December 30, 1981, letter on the same subject.
These attached tables convert the potential transformer readings taken during testing to voltage readings for the Emergency Safeguards Bus switchgear and motor control centers and the 230 KV grid.
Very truly yours, S J 6.
