THIS IS A 10 CFR PART 21 NOTIFICATION

January 30, 1995

Victoreen Inc
6000 Cochran Road
Cleveland, OH 44139-3395

Attention:  Quality Assurance Manager

Subject:  Spare parts supplied for Westronics chart recorder models S4N,
          D4N, T4N and 2100C.

Westronics has discovered that the possibility exists that some
nonconforming diodes may have been used in safety related spare parts
provided for the above noted instruments.

The offending parts are generic 6.3 V zener reference diodes 1N825
(Westronics part number SE01N825-00).  These particular diodes are easily
identified as they are flat black in color with a gray band.  These
diodes were mixed in with other diodes received from an electronics
component distributor.

An internal purge was performed in August of 1994 in our commercial
production when the nonconforming diodes were discovered.  All existing
stock was purged because good and bad diodes were mixed together in
stock.  Westronics felt at the time that all of the bad components had
been accounted for.  However, recent service activity performed for GPU
Nuclear Oyster Creek on some commercial recorders (D4E3) revealed that
some nonconforming diodes had been dedicated from our commercial stock
and supplied in safety related spare parts.

The 1N825 diode is used to generate reference voltages in the signal
conditioning circuits of the noted instruments.  The nonconforming diodes
are "noisy" and cause a drift in calibration of the host instrument.  The
diodes are found on the CB100124N02 and CB100124N04 signal input boards
for the S4N, D4N and T4N series and the CB100243C01 ADC board for the
2100C series.

Spare parts possibly containing the defective components have been
supplied to you on the following purchase order:
Customer PO:        49893
Westronics Part:    CB100124N02    Lot: 0048910   Qty: 15

You may obtain replacements or return boards for repair by contacting
Westronics Recorder Service department at 1-800-433-2184.

Proper notification has been made to the NRC.

For further information, please contact the undersigned at (713) 
348-1780.

Sincerely,

Westronics Inc.
