TS 3.6.1.3 requires that both containment air lock doors be closed except for transit entry and exit. The licensee implements this requirement, in part, with procedure 0-ADM-009, Containment Entries When Containment Integrity is Established, which states, in step 5.1.10, that to comply with
technical specification 3.6.1.3, both personnel hatch airlock doors shall be maintained closed when actual transit is not in progress. Contrary to the above, on September 18, the inner personnel hatch airlock door was not maintained closed when two personnel entered the Unit 4 containment for plant operations (operate lighting, search for and operate a valve). The condition lasted for approximately 25 minutes until the individuals exited containment and closed the inner door. The finding was more than minor because it was associated with the integrity of the reactor containment, and was of very low safety significance because one containment door remained closed during the entry. When identified to the licensee on September 24, 2008, after an individual questioned procedure compliance from the entry, the licensee documented the occurrence in condition report 2008-29525, and initiated an investigation.
