          FAN MOTOR BEARING INDICATIONS

          INTERIM 10CFR21 NOTIFICATION



Gentlemen:



Title 10 of the Code of Federal Regulations, Part 21 (10CFR21) requires

that licensees evaluate deviations and failures to comply, and report

those that could create a substantial safety hazard.  Section 21(a)(2) of

10CFR21 requires an interim report if the required evaluation cannot be

completed within 60 days.  This letter is an interim report per

10CFR21.21(a)(2) regarding a deviation that TU Electric is evaluating for

reportability per 10CFR21.



During receipt inspection of spare fan motor bearings for IEEE Class 1E,

ANSI Safety Class 3, Uninteruptible Power Supply (UPS) Room Fan Coil

Units (FCUs), small linear indications were discovered on the outer race

of the shielded face of the bearings.  The indications are located

circumferentially on the outer perimeter of the shielded face for greater

than 180 degrees.  TU Electric documented this deviation on November 30,

1995.  The bearings were manufactured by FAFNIR and were provided as

spares for four FCUs, which were provided by Ellis and Watts.  These four

FCUs passed receipt inspection and have been installed in the plant,

however, construction is not complete and the FCUs have not been declared

operable.  The possibility exists that defective bearings may be

installed in the four FCUs supplied by Ellis and Watts.  Operability of

the currently installed UPS Air Conditioning Units is not affected

because these units were supplied by a different vendor (CVI

Incorporated).



TU Electric's evaluation to date has not identified a deviation which

could create a substantial safety hazard.  Further evaluation of this

deviation is required and the evaluation will be completed by February

29, 1996.

As required by 10CFR21, TU Electric will notify the NRC if the evaluation

concludes that this deviation could create a substantial safety hazard.



                                        Sincerely,



                                        C.  L.  Terry
