. When. one containment air lock.door is inoperable, the'perable.air lock door must be maintained closed..
Each of these events was-initiated by a failure.of the outer door followed by unauthorized use. of the inner door.
The applicable LERs and response to violation 50-400/87-21 illustrate CPSL's corrective actions.
These corrective actions addressed both the reliability of the door and the administrative control over opening the door.
In summary, the corrective actions included:
LER 87-034-00 and Violation 50-400/87-21 (June 12 1987 incident) 1.
The Seals on the inner and outer personnel air lock doors were replaced.
2.
Sign was posted on the outer door as a reminder to notify the Main Control Room prior to entry.
