Upon questioning the person in charge of this operation, it was detemined that plant procedures were willfully violated.

AflALYSIS OF OCCURREliCE: Secondary containment is required to minimize any ground level release of radioactive materials which might result frem an accident. The ability of secondary containment to perfom this functicn with both airlock doors open was degraded. Considering the length of time concerned the safety significance of this event is considered minimal.

CORRECTIVE .

ACTI0ft: The contractor personnel were reinstructed on the Rx Building door interlock purpose and the seriousness of this event.

Additionally, plant management directed that the responsible supervisor in charge of this job for the contractors be ter-minated due to his lack of adherence to plant procedure.
