DESCRIPTIONv

On .11/08/89 at 1716 hours, with the Unit in Cold Shutdown,

1 (Operating Mode 5), a routine radiation barrier check identifieda faulty door locking mechanism. The north barrier door to theEast Valve Trench Area on the 722 foot elevation of the Primary' Auxiliary Building was found closed and unlocked. This door wasverified locked at 0808 hours earlier the same day. This door,

t ' restricts access to a High Radiation Area. A High Radiation'

Area is an, area with a- radiation field of greater than 100millirem per hour but less than 1000 millirem per hour-(mrem /hr). Technical Specification 6.12.2 requires HighRadiation Areas to .have locked- doors preventing unauthorizedentry. Entry is controlled through the use of keys which are

!, authorized- by the Nuclear Shift Supervisor. This event is beingreported in accordance with 10CFR50.73.a.2.1.B, as a conditionin violation of Technical Specifications.

. ROOT CAUSE OF THE EVENT

The cause for this event 'was attributed to a faulty doormechanism. . The locking mechanism would not operate correctlydue to welded latching mechanism plate which interfered with thelocking action of the door. The latch was found to flip back

.this event:

Immediate:

|1. The area was immediately searched to ensure nounauthorized individuals were in the area. No Iindividuals were in the area. I

l

|2. All individuals that signed out RB1X keys wereinterviewed to identify individuals who accessed the Iarea.

3. Personnel exposure reports for individuals working incontrolled areas, including those who has signed outRB1X keys were reviewed and no anomalies wereencountered.
