NRC Letter, Keppler to Linder, dated August 7, 1979.
Dear Mr. Keppler:
Your letter (Reference 1) requested a determination to insure current alarm systems and evacuation announcement systems are clearly audible or visible throughout all plant areas.
The LACBWR makes use of three sirens, one within the Containment Building, one within the Turbine Building and the third unit is installed on the ventilation stack.
All three sirens have been tested at plant operating noise level and we have concluded that the three sirens are clearly audible inside and outside all plant areas to the 1109 radius exclusion line.
A test as completed for all areas within and outside the plant throughout the 1109 radius exclusion area to insure the installed P.A.
system would be clearly audible above plant operating noise levels.
The twenty-seven area annunciators were tested; of the twenty-seven, six units were adjusted to bring the volume to clearly audible levels.
The P.A.
speaker located in the Genoa Site Switchyard was found to be inoperative.
A new connection cable was routed to this location and the area has been reconnected.
A new speaker was installed and is now operating properly.
All area radiation monitors' and plant mobile particulate monitors' audio and visual alarms, both local and remote, have been tested satisfactorily.
