Schmitendorf 82-12 (A) (3) At 1214 on March 8,1983 the unit was returned to on-line following replacement of the Main Generator and Main Transformers. Prior to placing the unit on-line, a

" Loose Parts" alarm was received indicating a loose part may exist in the secondary side of "C" steam generator.

The decision was made to place the unit on-line and escalate to 30% power to evaluate the loose part indication at higher feedwater flows and to allow completion of main generato- and main transformer testing under loaded conditions.

83-01 (H) (1) At 2120 on March 8, 1983, following completion of main generator and main transformer testing, the unit was ramped off-line and cooled down to Mode 5 for inspection of the "C" steam generator. Inspection of "C" steam generator was required as a precautionary measure due to

" Loose Parts" indication received prior to placing the unit on-line and which continued during operation at 30%.

A thorough inspection of the "C" steam generator determined that there were no loose parts in the steam generator. The unit was returned to power and placed on-line at 2330 on March 13, 1983 and reached 100% power at 2249 on March 18, 1983.
