Title | Sulfuric Acid Spill Requiring Offsite Notification |
Event Description | In the owner controlled area, the plant has a tank of sulfuric acid (93% concentration, UN # 1830) for chemical control of the Circulating Water system used in the non-safety related electrical power production portion of the plant.
At 0600 [CDT], a routine inspection of the tank found acid within the berm surrounding the tank. A leak was discovered in the berm and sulfuric acid leaked onto the surrounding area and nearby drainage ditch. The quantity of leaked acid has been estimated to be 120 gallons. The source of the leak has been determined to be a pipe on the tank and it has been isolated with a closed valve. The tank level has been stable for 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />. The leaked acid is contained within approximately 70 linear feet of the [limestone] ditch and has not left the site. On-site operations and chemistry personnel are neutralizing the acid with soda ash and a tanker truck was contracted to arrive on site this morning to empty the acid tank contents until a repair can be accomplished. The leak was discovered at 0600 and isolated about 0630 CDT. The licensee notified the NRC Resident Inspector. |
