Foxboro M/66R Dynamic Compensator

Model Number: 66RT OLB

Serial Number: 1976469



Each of the above listed items was found to have 1 Capacitor in each unit

installed with reverse polarity.  This could cause the units to fail to

operate however, units returned Integrated Resources, Inc.  to date have

been fully functional.



DATE THE INFORMATION WAS DETERMINED:



May 19, 1998



LOCATION OF ITEMS WHICH COULD BE POTENTIALLY AFFECTED.



Nine Mile Point, Units 1 & 2



Perry Nuclear Plant



Dresden Nuclear Plant



Oyster Creek



Clinton



Fitzpatrick



Southern Testing Service



CORRECTIVE ACTION BEING TAKEN.



Integrated Resources, Inc.  has notified each of the above listed plants

that a 10 CFR 50 Part 21 notification was being made.  To date, this

notification has been by telephone, however, within the next few days a

formal written notification will be supplied to each plant detailing the

Purchase Orders affected, if requested, a list of the manufacturer, model

numbers, and serial numbers of all affected equipment.  This written

notification shall be completed by June 5, 1998.



Effective May 1, 1998, Integrated Resources, Inc.  adopted a policy of

second checking of all capacitors to ensure correct polarity of

installation.



ADVICE WHICH WILL BE GIVEN IN RELATION TO THIS POTENTIAL DEFECT.



Integrated Resources, Inc.  recommends that the clients perform a 100%

check of all units which are in spares for any incidence of capacitors

installed with reverse polarity, if not already accomplished.



For units which are installed and in use, Integrated Resources, Inc.

recommends that the clients perform a check of all units in conjunction

with the normal maintenance (i.e. loop calibration, surveilance testing,

system shutdown, Etc.).



Units found or suspected to have incorrectly installed capacitors as a

result of these inspections, may be returned to Integrated Resources,

Inc.  for verification and correction.



The basis for the above recommendations are as follows:



1.   The defectively installed capacitors are the result of random human

     error and to date appears to be of very limited scope (< 1 % of

     units and < 0.1 % of capacitors).



2.   All units have succesfully passed testing to manufacturers

     specifications prior to release to the clients.



3.   Integrated Resources, Inc.  has not been informed of any unit

     failures as a result of defectively installed capacitors.



4.   Integrated Resources, Inc.  believes all units to be used in fail

     safe or non-safety related applications and is therefore of very

     limited safety significance.



5.   The result of a capacitor being installed with reverse polarity may

     be that; (1) the capacitor vents and the plates remain open with the

     resultant loss of capacitance, the result of which may or may not be

     failure of the unit, (2) The capacitor vents and the plates close

     thus shorting the capacitor which would likely cause failure of the

     unit, or (3) the capacitor continues to function, the result of

     which may be an indeterminate decrease in expected life span of the

     capacitor.



                                        Sincerely,



                                        John F.  Brosemer

                                        President

                                        Integrated Resources, Inc.
