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."
