Title	Helb Door Not Latched as Required Due to Personnel Error
Event Description	A High Energy Line Break (HELB) door was not latched as required. This condition is being reported as an event that could have prevented the fulfillment of a safety function in accordance with 10CFR50.72(b)(3)(v)(A). The door is currently closed. The HELB door which separates two critical Motor Control Center [MCC] areas was unlatched for less than two (2) minutes. The licensee will inform the state representative and has informed the NRC resident inspector. * * RETRACTION on 08/27/03 at 1216 EDT by R. Sand to John MacKinnon * * * Because plant safety was not significantly degraded, this event is not reportable under the unanalyzed condition criteria based on: (1) the door in either event was in an uncontrolled condition for less than one minute, (2) the door was not materially affected, only operated improperly, (3) the PRA significance of the event was low, and (4) the HELB Barrier door was not open for a period longer than is allowed by station procedural guidance. R3DO (C. Miller) notified. The station continues to review the event in the station's corrective action program. The NRC Resident Inspector was notified of this retraction by the licensee.
