Title	Degraded Condition Due to Rcs Pressure Boundary Leakage
Event Description	At 1032 [EDT] on October 4, 2003 while in mode 4 conducting a planned refueling outage reactor coolant system inspection, Crystal River Unit 3 identified two potential RCS Pressure Boundary Leaks located in Pressurizer penetrations associated with upper level sensing lines. Upon closer inspection of the first one inch penetration, indications confirmed a Pressure Boundary Leak. A closer inspection of the second penetration is planned after obtaining access to the location. The last unidentified leak rate that was completed prior to the plant shutdown was 0.15 gpm. This defect in the primary coolant system is not acceptable per ASME XI. This condition is REPORTABLE per 10CFR 50.72 (b)(3)(ii)(A). Licensee reported that a small amount of boric acid residue and residual rust was identified during inspection in the vicinity of the upper level Pressurizer tap near the Pressurizer shell and the nozzle. A closer inspection is planned of the other two upper Pressurizer level taps. The NRC resident has been notified by the Licensee.
