FLORIDA POWER CORPORATION CRYSTAL RIVER UNIT 3 DOCKET NUMBER 50-302/LICENSE NUMBER DPR-72 ATTACHMENT A NRC Question and FPC Response
U.S. Nuclear Regulatory Commission Attachment A 3F0702-01 Page 1 of I NRC Question Your 15-day response to Bulletin 2002-01 states that you cleaned the reactor pressure vessel (RPV) head in 2001. Following the cleaning of the RPV head, were any significant deposits left on the head (i.e., deposits that prevent seeing the bare metal of the head for an area greater than 1 square inch).
FPC Response The Inservice Inspection (ISI) group performed the as-found RPV head inspection and subsequent head inspection after cleaning during the Fall 2001 refueling outage. The entire RPV head was visually examined. These examinations revealed evidence of boron on the RPV head.
One leaking Control Rod Drive nozzle was found and repaired. Other boric acid deposits were determined to be from previous flange leakage. The deposits were cleaned with water and another visual inspection was performed. A slight sheen was left on the RPV head in some areas, but the bare metal of the RPV head was still visible. This sheen was due to old boric acid residue being left on the head after the water had dried following cleaning. Attachment B contains pictures that were taken immediately after the RPV cleaning. These pictures show some shine caused by water that had not yet dried on the RPV head. Attachment C provides additional pictures that were taken after the RPV head was totally dry.
The visual inspection performed after cleaning the RPV head revealed that there were no significant deposits left on the head.
