On April 6, 1982, while preparing for a gaseous release, the Control Room Operator noticed that the sample pump for the containment-plant vent radioactivity monitors was de-energized.

An investigation of the problem revealed that the air supply to Sample Valves IVC 8 and IVC 10.had been tagged out for maintenance.

The valves had failed in the closed position, causing the. pump to trip on thermal overload.

The monitors were declared in-operable, and Limiting Condition for Operation 3.3.3.1 Action l
