Title	Secondary Containment Inoperable Due to an Unattended Open Door
Event Description	Security personnel reported to the Main Control Room that at time 1437 CDT, an alarm indicated that a secondary containment door was open beyond the normal delay time allowed for entry and exit. Security personnel responded and found the door open and unattended with the dogs extended meaning that the door was unable to be closed. Security personnel secured the door at time 1441 CDT. No deficiencies were found with the door. The fact that the door was open and unattended beyond the time allowed for normal entry and exit violates Technical Specification 3.6.4.1, 'Secondary Containment- Operating,' because surveillance requirement SR 3.6.4.1.3 was not met. This surveillance requires that doors be closed except during normal entry and exit. In summary, an SSC was inoperable in a required mode as a result of a personnel error and no redundant equipment in the same system was operable. Thus, the condition is reportable under 10CFR50.72(b)(3)(v)(D). The licensee notified the NRC Resident Inspector.
