Nuclear Regulatory Commission Document Control Desk Washington, DC 20555 SUBJECT: COMANCHE PEAK STEAM ELECTRIC STATION (CPSES) DOCKET NOS. 50-445 AND 50-446 FAFNIR BEARING DISCREPANCIES 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 refurbishment of a safety related Limitorque actuator, it was noted that the replacement bearings obtained from the warehouse did not rotate freely. Other sets of replacement bearings for this actuator obtained from the warehouse exhibited similar characteristics. TU Electric documented this deviation on June 12, 1997. The bearings were manufactured by Fafnir (Fafnir S7K Bearing, RGP2559). These bearings had previously passed receipt inspection, but had not yet been installed in the plant. 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 November 11, 1997. P. O. Box 1002 Glen Rose Texas 76043 TXX-97170 Page 2 of 2 As required by 10CFR21, TU Electric will notify the NRC if the evaluation concludes that this deviation could create a substantial safety hazard.
