Title	Inadvertent Offsite Notification During Simulator Training
Event Description	At 0749 PDT on March 21, 2012, during a training scenario in the plant simulator, plant personnel inadvertently issued an Alert notification for Diablo Canyon Power Plant (DCPP), Unit 1. This Alert should be disregarded. The Alert was issued as a loss of the Unit 1 fuel cladding barrier with no radioactive release. There is no Alert declaration at DCPP Units 1 or 2, and both units are operating normally. DCPP contacted notified parties to clarify that the Alert notification was inadvertent. DCPP is making this 4-hr, non-emergency notification under 10 CFR 50.72(b)(2)(xi) as a situation for which an (inadvertent) notification to other government agencies has been made. The licensee is investigating this inadvertent notification but believes that the notification system was still set up from the emergency plan drill which was conducted last week. The licensee notified the NRC Resident Inspector, San Luis Obispo County, and the State.
