Title | Offsite Notification Due to Water Seepage on an Onsite Structure |
Event Description | A verbal report was made to the Federal Energy Regulatory Commission (FERC) Engineer on January 11, 2010 at 1510 hours0.0175 days <br />0.419 hours <br />0.0025 weeks <br />5.74555e-4 months <br /> pursuant to 18CFR12.10(a) for a condition affecting the safety of a project or works. A new wet area has been identified on the slope of Dike 6, approximately 25 feet from the top of the structure. Dike 6 was designed and created during original plant construction to support electrical towers and provide isolation between Lake Anna and the proposed Unit 3 & 4 intake structures. The Unit 3 & 4 intake area is currently being used as a settling pond. The settling pond is used to process storm water and other secondary water before the liquid is discharged from the station.
This minor seepage is located about half way down the slope to the settling pond. Water samples were obtained from the wet area and it was determined that the seepage was not ground water. The sample composition was similar to the water in Lake Anna. Currently, there is no threat to the public or North Anna Power Station. Engineering is investigating this issue and a corrective action plan will be developed to correct the minor seepage. This issue is being reported pursuant to 10CFR50.72(b)(2)(xi). The licensee has notified the NRC Resident Inspector and the local government. |
