Event Description | This is a Non-Emergency 4 hour4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> notification being made in accordance with 10CFR 50.72(b)(2)(xi), an Offsite Notification. On October 4, 2010, at 1500 CDT, the Waterford 3 Operations supervision was notified by the Outside Operations watchstander that there appeared to be a diesel oil film from upstream of the Mississippi River collecting on the upstream side of the Waterford 3 non-safety related Circulating Water intake weir. The Chemistry Department environmental expert went to investigate with the Outside watch and verified that a diesel film was washed upon the north wall of the weir at the shore line forming about a 50 square foot sheen of diesel. Safety systems are not impacted by this condition.
At 1609, the National Response Center was notified of the discovery of the sheen at our intake from an unknown source upstream. The incident report number was 956006. The Coast Guard was notified and the Waterford 3 environmental chemist received a call from the Coast Guard requesting information. The information was confirmed that a diesel film was washed upon the north wall of the intake structure weir at the shore line forming about a 50 square foot sheen of what appears to be red colored diesel. At 1734, Louisiana Hazardous Materials Hotline was notified (IR# 10-05779). The licensee notified the NRC Resident Inspector. |
