10CFR, Part 21 Notification
Dear Sir:
In accordance with Mercury Company's procedure for reporting 10CFR, Part 21 Defects and Noncompliance, we are providing notification of a potential reportable condition.
On September 20, 1988 we received written notification (copy attached) from Rochester Instrument Systems, Inc., Rochester, NY advising that several parts shipped to Mercury could fail under non-standard operating conditions.
They recommended the parts be rep 1hced and provided new parts and replacement instructions for same.
Additionally, their report indicates they notified the NRC on 8/31/88 of this 10CFR, Part 21 condition.
Mercury Company immediately initiated an investigation and determined that the items in question were installed into Emergency Core Cooling System Analog Trip Cabinets Nos. C-2233A and C-2233B which were shipped to Boston Edison Company's Pilgrim Nuclear Station on 12/13/85 and 1/16/86 respectively.
Three (3) units were installed in each cabinet and two (2) units were furnished as spares.
l Oral notification was provided to Mr. Frank Schellenger - Boston Edison i
Co. QA Supervisor via telephone on September 22, 1988. Written notice was fotwarded to F.N. Famulari, CA Manager by f ax machine and U.S. Mail also on September 22, 1988 (copy attached).

y A HSCHBACH COMPANY Office of Nuclear Reactor Regulation September 27, 1988 Pagw 2 In subsequent phone cor.versations with Boston Edison's Frank Sche 11enger, Don Richards and Kathy Ward on September 26, 1988, we were advised that Boston Edison is initiating an engineering evaluation of this condition which could take as long as two weeks.
They also indicated they had not notified the NRC and'probably would not until their evaluation was complete.
Kathy Ward requested that Boston Edison be informed if Mercury notified the NRC.
As Mercury's proc 9 dure calls for notification to the NRC if the Owner does not provide the notification, Mercury contacted the NRC office at King of Prussia, Pennsylvania on September 26, 1988.
This regional office directed us to the Vendor Inspection Office in Washington, D.C. where the above information was provided to Mr. Uldis Potapuvs.
He advised this written report be sent to your office.
If you have any questions or require further information, please contact the undersigned.

Dear Sir:
Attached is a copy of correspondence received f rom Rochester Instrument Company relative to a NRC 10CFR, Part 21 Report of Defect. Oral notification k
was provided to your Frank Schellenger at 11:00 a.m. on September 22, 1988.
The signal converters were furnished as components in the Emergency Core Cooling System Analog Trip Cabinets C-2233A and C-2233B which were shipped to Pilgrin Station by Mercury on 12/13/85 and 1/16/86 respectively. Threc ( 3)
Units were installed in each cabinet and two (2) Units were furnished as spares.
Mercury is in possession of replacement Signal Convertors and capacitors.
Please advise where Mercury should forward those components necessary to repair the defect.
In accordance with Mer tu ry's proceduce for reporting 10CFR Part 21 conditions, we will be notifying the Office of Inspection and Enforcement U.S.

Install the unit to be tested into the temperature chamber. Monitor the output signal with a 4 1/2 digit voit meter and ensure that the input source is stable i
l and does not drift over time. Apply power to the unit l
under test and observe the output of the unit at ambient temperature. When the output has stabliced, record both the output and the temperature from the thermometer. Set the temperature chamber for 25

After recording the data G 25*F, sot the oven temperature for 12S*F. Again allow at least 2 hrs. before recording the output and temperature. Return the oven temperature
-u to 75'F and remove unit from chamber. Refer to step 9.0 to evaluate temperature performance.
i 10.0 Recompensation far Exqnan Temp. Drift: SC1326W-323 only If a unit displays drift characteristics exceeding the Max. allowed spec. (10Mv./ Input Gpan x.02% per Dog. F),
an adjustment or recompensation of the unit must be performed. This recompensation is done by readjusting the mV. setting across R13 (refer to Step 8.0). The l
i
- iew setting is determined by first deriving a correction l
factor (CF), then subtracting CF from the corresponding l
compensation coefficient (T/C x), listed in table 9.4a. Finally, the sum of T/C e-CF is multiplied b>
the temperature (T) plus 459. G7 Dec. F (Ref, absolute sero).
