YEAR 1982 DATE 08-06-82 COMPLETED BY G. D. Schmitendorf 82-12 (H) (1) At 2230 on July 2, 1982 with the unit at 100% power a rampdown to 30% reactor power was commenced to evaluate a " Loose Parts" Alarm received on "A" S/G. After stabilizing at 30% power to obtain data a rampdown from 30% to generator off line was commenced in order to further evaluate the " Loose Parts" Alarm and obtain more data. The generator was off line at 0418 on 3 July. Reactor maintained critical. The data taken was eval-uated and the loose part was determined to be of low impact energy and on the secondary side of the "A" S/G. During the unit down time sdditional " Loose Parts" noise monitoring pick-

, ups and data gathering equipment were installed to ascist in locating the region that the noise originated from and determination as to what components were the causc.

82-13 (H) (1) At 2100 on July 7 with the unit at 100% power a rampdown at 150 mwe per hour followed by i normal reactor shutdown was commenced.

The generator was taken off line at 0113 on July 8. The reactor shutdown was commenced at 0135 by driving in the

, control rods placing the Unit in Mode 3. The Unit was taken to l cold shutdown (mode) to investigate the noise monitored in "A" S/G. Upon removal of S/G side handhole cover, the Tube Lane i Blocking device split plate was found to be loose. The TLBD was repaired and reinstalled. During the time frame of the S/G I

loose parts investigation it was decided to "UT" the Thermal l Sleeves installed in the RCS.
