| Title | Tech Spec. Required Shutdown Due to 72 Hour Completion Time Not Met |
| Event Description | At 1819 hours0.0211 days <br />0.505 hours <br />0.00301 weeks <br />6.921295e-4 months <br />, an orderly shutdown on Unit 1 commenced as the result of Technical Specification Action Condition (TSAC) 3.7.5.B.1 completion time of 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> not being met for the 1P-29 turbine-driven auxiliary feedwater pump. The pump was declared inoperable on June 12, 2007, at 0131 hours0.00152 days <br />0.0364 hours <br />2.166005e-4 weeks <br />4.98455e-5 months <br /> as a result of high pump bearing temperatures. Repairs and testing performed to date have not satisfactorily resolved the problem.
This non-emergency notification is being made in accordance with 10CFR50.72(b)(2)(i). The PBNP resident inspector has been notified. The licensee plans to conduct an extended duration test of the 1P-29 AFW pump. This test is scheduled to commence shortly and will last approximately 4 to 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />. The licensee will have two different hold points in the test to take pump bearing temperature data. The licensee has one emergency diesel generator (EDG) out of service (OOS), but an alternate EDG is aligned to ensure all four vital buses have vital power in the event of an loss of offsite power. No other safety related systems are OOS at this time. The licensee notified the NRC Resident Inspector.
This is an update to EN#43424: Regarding Unit 1 turbine driven auxiliary feedwater pump inoperability and Technical Specification required shutdown. PBNP Unit 1 entered MODE 3 on 6/15/07 at 0407. PBNP Unit 1 entered MODE 4 on 6/15/07 at 1712. Technical Specification Action Condition 3.7.5.D.1 required Unit 1 to be in MODE 3 by 0731 and MODE 4 by 1931 on 6/15/07. All Technical Specification Required Actions for the AFW pump OOS have been met within the required times. The licensee informed the NRC Resident Inspector. Notified R3DO(Stone). |
