The rampdown was due to a malfunction of the cooling fans on "C" Main Transformer. At 0815 on November 18, 1983 a manual reactor trip was initiated.

The repairs were made and re.ector start-up commenced at 1334 and by 1451 on November 18, 1983, the reactor was critical. On November 19, 1933 at 0112, Unit I was on line, and at 0425, November 20, 1983, Unit I was at 100%
