Dear Dr. Murley:

POTENTIAL CONSTRUCTION DEFICIENCY G. H. BETTIS HVAC DAMPER ACTUATORS HOPE CREEK GENERATING STATION On May 3,1984, a verbal report was made to Region I, Office of Inspection and Enforcement representative, Mr. E. C.

McCabe, advising of a potentially significant construction deficiency concerning four (4) actuators manufactured by G. H. Bettis and installed on HVAC dampers supplied by American Warming and Ventilating, Inc. On June 1, 1984, an interim report was sent to your office. The following information is provided in accordance with 10CFR50.55(e).

Our Architect / Engineer and Constructor, Bechtel, has evaluated the reported condition to determine its potential effect on safe operation of the plant. It was determined that the affected dampers are to be installed in the Reactor Building Filtration, Recirculation and Ventilating System (FRVS) and the Containment Prepurge Clean-up System (CPCS). In operation, the dampers are normally closed and would fail closed. Since the dampers are used only for FRVS testing or drywell purge, they are only operated manually under administrative control.

All of the danipers are provided with position switches and pilot lights to indicate the full open or closed position.

The plant operator would be alerted to a problem with abnormal damper operating time or failure to achieve full open or closed position by observing the damper position pilot lights.
