Dear Sir:

In Reference (b), we reported a 10CFR50.55(e) deficiency regarding Westinghouse W-24 Operational Amplifiers. This deficiency is associated with Westinghouse NAL cards having W-24 amplifiers with date code 8101.

As indicated in Reference (c), if an on-line calibration check of any cards containing these amplifiers was performed during normal operation, the amplifiers may oscillate resultiug in setpoint shif t.

The corrective action, provided in Reference (c), replacement of Westinghouse NAL cards having W-24 operational amplifiers with date code 8101, has been completed. As such, this is considered our final report on this item.

Very truly yours, p H John DeVincentis Director of Engineering cc: Atomic Safety and Licensing Board Service List Director, Office of Inspection and Enforcement United States Nuclear Regulatory Commission Washington, DC 20555
