Safety Assessment
A review of the VA door logs for access by the individual involved showed that he had only entered the VA for very short periods, validating that his VA entries were for the legitimate purpose of obtaining keys to the mobile crane he was to operate.
I A review of all active badges identified no badge set for more access than was intended (other than the individual's badge that triggered this investigation).
All personnel granted any PA or VA access have passed Unescorted Access Authorization. However, they are only administratively cleared to enter specific areas based on job need. Therefore, this event did not allow anyone without Unescorted Access Authorization to enter any Vital Area of the plant. A three year review was conducted of all badges incorrectly assigned wrong access levels by the computer and no other entry into an area not administratively cleared occurred.
Therefore, this event did not result in anyone without Unescorted Access Authorization entering the Protected Area or Vital Area.
I
Corrective Action
I With vendor assistance an enhanced procedure for setting badge access was developed and implemented on March 16, 2006 to prevent incorrect assignment of access levels.
I The vendor developed a software patch that was installed and tested satisfactorily on April 5, 2006.

Additional Information
There have been no similar LERs in the past two years.
