| Title | LICENSEE-IDENTIFIED Violation |
| Description | TS 3.6.1.2 states two primary containment airlocks shall be operable. Contrary to this requirement, on May 10, 2008, the 208-foot elevation airlock inner containment door was partially open and a plant instrument and controls technician was able to open the outer door at the same time. This resulted in a momentary breach of containment for approximately 2 minutes. The reason both doors were able to open at the same time was a result of the following issues: high door closure rate due to air in the hydraulic lines, twisted/damaged lower hinge pin, and worker not complying with procedural requirements to manually assist the door closed. Upon discovery of this TS violation, the Limiting Condition for Operation required actions were taken within the required time frame to close at least one containment air lock door within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />. Due to the licensee being able to restore containment integrity within the required action time, the exposure time being of short duration and the licensee entering this into its CAP as CR-GGN-2008-2317, the finding is considered to have very low safety significance |
