Title | Sewage Spill in the Turbine Building That Discharged to the Keowee River |
Event Description | On 2/26/13 at 2030 hrs [EST], a four (4) inch sewage line in the Oconee Nuclear Station turbine building failed. This failure allowed sanitary wastewater to spill into the turbine building basement. An estimated 750 gallons entered into trench drains and traveled to the station sump which discharges into the conventional wastewater system. This conventional wastewater system is discharged to the Keowee River from NPDES (National Pollutant Discharge Elimination System) outfall 002. The discharge of outfall 002 is into the Keowee River below the Keowee Hydro Station. The normal discharge path for sanitary wastewater is to the City of Seneca, South Carolina (SC). South Carolina Department of Health and Environmental Control (SCDHEC) and the Oconee Joint Regional Sewer Authority (OJRSA) were notified of the spill on 2/27/13 at approximately 1358 hrs [EST].
Note: SCDHEC requires the reporting of any overflow that reaches waters of the state, for overflows that exceed an estimated 500 gallons that don't reach water, and for any overflow that may cause a public health or environment concern. This event was determined to be reportable pursuant to 10CFR50.72(b)(2)(xi) due to notification of the SCDHEC and OJRSA. Initial Safety Significance: The sewage leak did not contain any plant produced radiological material and due to dilution, this event posed no safety risk with respect with respect to the health and safety of the public. Corrective Actions: The affected portions of the sanitary sewage system has been isolated and an investigation is underway to determine the cause. There was no impact on plant operations, and the cleanup has been completed. The event was entered into the correction action program. The licensee notified the NRC Resident Inspector. |
