A subeksary of Thermo instrument Systems Inc. '
tills IS A 10 CFR PART 21 NOTIFICATION January 30,1995 Nuclear Regulatory Commission Document Control Desk Washington, D.C. 20555
Subject:
Spare parts supplied for Westronics chart recorder malels 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 ofTending parts are generic 6 3V zener reference diodes 1N825 (Westronics part number SE01N825-00). These particular diodes are casily 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 discoverest All existing stock was purged because gaxi and bad diodes were mixed together in stock. Westronics felt at the time that all of the bad components had been accounted for. Ilowever, service actisity performed for GPU Nuclear Oyster Creek in January,1995 on some commercial recorders (D4E3) revealed that some nonconfonning diodes had been dedicated from our commercial stock and supplied in safety related spare parts.
Tbc l N825 diode is used to generate reference voltages in the signal conditioning circuits of the noted instnunents. The nonconfonning diales are " noisy" and cause a drift in calibration of the host instrument. The diodes are found on the CD100124N02 and CB100124N04 signal input boards for the S4N, D4N and T4N series and the CB100243C01 ADC board for the 2100C series.
Westronics has been able to precisely detemiine which customers may have received spare parts with the bad diodes. A list of affected license holders and other recipients is attached for your reference. All customers on the list have received a similar notification.
Customers may obtain replacements or retum boards for repair by contacting Westronics Recorder Service department at 1-800-433-2184.
For further infonnation, please contact the undersigned at (713) 348-1780.
Sincerely, Westr 4 1 ,
