Re:       10 CFR PART 21 - Notification of Deviation



As required by 10CFR Part 21, the following information is to provide

notification of deviation in connection with two (2) Resistance

Temperature Detectors (RTD's) supplied to Niagara Mohawk Power, Nine Mile

Point Station:



1.  Name and Address of individual informing Commission:



          Mr. John V. Metzger Jr. - President - PYCO Inc.

          600 E. Lincoln Hwy.

               PENNDEL, PENNSYLVANIA 19047   215-757-3704



2.   Basic Component Supplied:



          - Resistance Temperature Detector (RTD) Assembly

          - PYCO Part Number (P/N) 122-4030-04-2.7-6.0

          - Two (2) pieces- PYCO Serial Numbers (S/N) 13006 and 15007

          - PYCO Shop Order (SO) #57985

          - Customer Purchase Order (PO) # 03015

          - Customer Material # 93-03-975



3.   Identification of the Firm supplying the basic component



          PYCO Inc.

          600 E. Lincoln Hwy.

          Penndel, PA 19047



4.   Nature of Deviation



          RTD 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.



5.   Date Detected:



          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 RTD's are within

          specification.  Verbal communication of the discovery of the

          nonconformance was provided to Niagara Mohawk on September 29,

          1997.  Since two RTD's 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.



               PENNDEL, PENNSYLVANIA 19047   215-757-3704

                    Penndel, PA 19047



7.   Corrective Action:



          A.   SIN 15006 - The RTD assembly is in operation at Niagara

          Mohawk PYCO to provide Cast Iron enclosure and installation

          instructions to Niagara Mohawk for replacement at site

          location.



          B.   S/N 15007 - Rework the RTD assembly, replacing the

          aluminum enclosure with a cast iron enclosure, inspect and

          return to Niagara Mohawk,



          C.   Review and update PYCO's Commercial Grade Item (CGI)

          dedication procedure to preclude recurrence.

          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.

10 CFR PART 21 REPORT - RTD ASSEMBLIES MANUFACTURED USING COVER

MADE FROM

ALUMINUM INSTEAD OF CAST IRON AS SPECIFIED.



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 SIN 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 TE 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 SIN 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."
