REPORTABLE OCCURRENCE 335-76-14 LICENSEE EVENT REPORT PAGE TWO EVENT DESCRIPTION (Continued)

Specification 3.6.1;3. The inner door was kept closed the entire time that the outer door was out of service. This was the first

.. occurrence of this type. (335-76-14).

CAUSE DESCRIPTION (Continued) tightly while the holding pin was bent. It is believed that the pivot arm became loose because of slamming of the access door or because of the high frequency of airlock usage necessitated by preparations for initial criticality. Signs have been posted which instruct personnel to operate the airlock doors carefully.
