DISCOVERY OF A CONDITION AFFECTING THE OPERABILITY OF CLOW       
(MANUFACTURER) VALVES INSTALLED IN THE UNIT 2 STANDBY GAS        
TREATMENT SYSTEM                                                 
                                                                 
THE LICENSEE DETERMINED THAT CLOW (MANUFACTURER) VALVES IN THE   
STANDBY GAS TREATMENT SYSTEM HAVE A DOWEL PIN INSTALLED WHICH IS 
NOT PEENED IN PLACE. SHOULD THESE DOWELS COME LOOSE, IT COULD    
INTERFERE WITH THE VALVE LIMIT SWITCHES AND PREVENT THE MAKEUP OF
CIRCUIT PERMISSIVES.
