~NO DATE ABSTRACT (Limit to 1400 spaces, i.e., approximately 15 single-spaced typewritten lines)
An unauthorized person gained access to the protected area. The individual's badge had been previously cancelled, but was able to access the protected area through the Main Access Facility (MAF). The individual was escorted out of the protected area by security. An ENS one hour notification was completed per 10 CFR 73.71(b)(1). This event affects both units due to the shared protected area.
The safety consequences of this event were minimal. The unauthorized individual displayed no malevolent intent to gain access.
The apparent cause evaluation determined that an authorized individual unlocked the turnstile, but stepped away for assistance. The authorized individual failed to perform proper human performance techniques for self-check. While the authorized individual was seeking assistance, an unauthorized individual accessed the protected area via the unlocked turnstile. Actions taken include coaching the individual on the proper human performance techniques when using vital doors or security access turnstiles.
This report is being issued based on the requirements of 10 CFR 73.71(d), Reporting of Safeguards Events within 60-days of the event.

OF 3
On March 3, 2010, at 07:47 an individual approved for protected area access inserted their security badge into the Main Access Facility (MAF) turnstile #5 card reader and received the proper response (green light on card reader and turnstile unlocked) for authorized entry. The individual believed that the proper response for accessing the plant was not received and stepped away from the entry point to obtain help from a Security Officer. Turnstile #5 remained unlocked. The Security Officer called the Security Control Center at 07:49. The Security Officer was informed that the individual had already logged into the protected area at 07:47. Security approved protected area access for the individual at 07:49. The individual entered the protected area through a turnstile manually unlocked
~~~
On March 3, 2010, at approximately 07:47, a second individual that was not authorized for protected area access inserted their security badge into the turnstile #5 card reader. The individual failed to identify that they had not received the proper response for entering the protected area and proceeded through turnstile #5 and entered the protected area. The individual was able to access the protected area through turnstile #5 because the turnstile remained unlocked from the previous individual's attempt to gain access. Once the individual passed through turnstile #5, the turnstile returned to the locked position.
The second individual, now in the protected area, identified that his co-workers could not gain access.
At approximately 07:58, the individual proceeded to the exit turnstiles. The individual inserted his security badge at the exit turnstile card reader and received an error message. Security immediately responded and took control of the individual.
At 08:25 on March 3, 2010, Security contacted the operations Shift Manager and notified him of the issue. At 08:51 CST an ENS one hour notification was completed per 10 CFR 73.71(b)(1). This event affects both units due to the shared protected area.
C. CAUSE OF EVENT
The cause of the event was that the authorized entrant did not follow the process for entering a vital door or turnstile. The individual did not enter or challenge turnstile #5. A contributing cause was that the second individual did not properly use human performance tools to validate access approval on indication at the security card reader.
