| Title | Rcs Through-Wall Leakage Found on Seal Injection Piping |
| Event Description | On October 19, 2003, during performance of surveillance test procedure, STP 250.001B, Boric Acid Inspection Program, boron was observed around the seal injection piping and on the pump case housing of reactor coolant pump (RCP) 'C.' Inspection personnel contacted the Control Room and Outage Management at 1350 hours0.0156 days <br />0.375 hours <br />0.00223 weeks <br />5.13675e-4 months <br />. Evaluation of the condition was initiated and a dye penetrant examination (PT) was scheduled for the morning of October 20. Evaluation of the PT results determined at 0700 hours0.0081 days <br />0.194 hours <br />0.00116 weeks <br />2.6635e-4 months <br /> on October 20 that the seal injection piping at the RCP pump case housing had through-wall leakage. This condition is being reported in accordance with 10CFR50.72(b)(3)(ii)(A)(2).
The licensee performed a similar inspection in April 2002 and found no indication of leakage at that time. Inspections of RCPs 'A' and 'B' have been completed during this outage with no indication of leakage observed. The licensee has corrective actions under review which will include additional UT inspections. The licensee informed the NRC Resident Inspector. |
