Title | Wrong Train Emergency Diesel Fuel Rack Trip |
Event Description | While hanging tags on the 'B' Diesel Generator, which was tagged out for maintenance, the operator mistakenly entered the 'A' Diesel Generator Room and tripped the 'A' Diesel Generator fuel rack, making it inoperable. At this time both diesels were inoperable placing the plant in a 24 Hour LCO.
When the fuel rack was tripped alarms were received in the control room, the operator was immediately contacted and the problem was identified and corrected. Total LCO time was approximately 2 minutes. The licensee notified the NRC Resident Inspector. |
