SUPPLEMENT TO LER 80-024/03X-1 THE AREA AT THE TIME OF THE EVENT. IT IS POSSIBLE THE PIECE OF LUMBER FELL FROM THE SCAFFOLD FROM VIBRATION OR ACCIDENTALLY DROPPED BUT THIS WAS NEVER CONFIRMED. FIELD INSPECTORS AND CRAFTSMEN WERE CAUTIONED TO REMOVE ALL LOOSE MATERIAL FROM AN AREA BEFORE LEAVING. THE TRIP AND" THROTTLE VALVE WAS RESET AND THE TURBINE DRIVEN AUXILIARY FEEDWATER PUMP WAS TESTED TO PROVE OPERABILITY.
