THE FOLLOWING IS TEXT FROM A FACSIMILE SUBMITTED BY THE VENDOR:  

                                                                 

"RTD [RESISTANCE TEMPERATURE DETECTOR] ASSEMBLIES WERE           

MANUFACTURED USING A SCREW COVER TERMINAL ENCLOSURE FABRICATED   

FROM ALUMINUM INSTEAD OF AN IDENTICAL APPEARING CAST IRON        

ENCLOSURE AS SPECIFIED ON THE ASSEMBLY DRAWING.                  

                                                                 

NIAGARA MOHAWK RETURNED S/N 15007 TO PYCO FOR CALIBRATION        

VERIFICATION (RMA4040). THE NONCONFORMANCE WAS DISCOVERED DURING 

OUR IN-HOUSE RECEIVING INSPECTION OF CUSTOMER RETURNED MATERIALS 

ON SEPTEMBER 19, 1997. THE CALIBRATION VERIFICATION WAS COMPLETED

ON SEPTEMBER 26, 1997 AND THE RTDs ARE WITHIN SPECIFICATION.     

VERBAL COMMUNICATION OF THE DISCOVERY OF THE NONCONFORMANCE WAS 



PROVIDED TO NIAGARA MOHAWK ON SEPTEMBER 29, 1997. SINCE TWO RTDs 

WERE MANUFACTURED IN SO#57985, PYCO INFORMED NIAGARA MOHAWK OF   

THE OTHER RTD ASSEMBLY (S/N 15006) THAT COULD HAVE BEEN          

MANUFACTURED WITH AN ALUMINUM ENCLOSURE. PYCO REQUESTED NIAGARA 



MOHAWK TO INSPECT S/N 15006 AND ADVISE PYCO OF THEIR RESULTS FOR 

CORRECTIVE ACTION DEVELOPMENT, AS REQUIRED.                      

                                                                 

BOTH THE ALUMINUM AND CAST IRON ENCLOSURES ARE APPROVED FOR USE  

IN NUCLEAR APPLICATIONS AS VERIFIED BY QUALIFICATION TESTS AND   

ARE ROUTINELY USED IN NUCLEAR POWER PLANTS."
