~1985 STEAM GENERATOR INSERVICE INSPECTION REPORT In accordance with P~lisades Technical Specificatiq'.n 4.14.6, the enclosed Steam Generator Inseivice Inspection Report is sub~itted.

The inspection occurred from December 1 to December.' 30, 1985 when the final tube plugging occurred. A total of eight (8) tubes,;.were plugged following the inspection; all were located in "B" Steam Generator:"* (see Attachment 5 for details). The number of tubes plugged does not vJoi~te the assumptions or change the safety analysis. ,I "

It is Consumers Power Company's belief that the str1'cf *adherence to secondary water .purity limits and maintaining the secondary s'a:de of the steam generators in wet lay-up, as much as possible, during non-oper~ting conditions has limited tube corrosion. The results of 1985 inspec~ion show, essentially, no further degradation of the "A" or "B" steam generat~r tul;>ing occurred during the last operating cycle.
