llouston Lighting & Power June 5, 1995 ST-HL-AE-5100 File No.: G26 10CFR50.73 U. S. Nuclear Regulatory Commission Attention: Document Control Desk Washington, DC 20555 South Texas Project Unit 2 Docket No. STN 50499 Revision 1 to Licensee Event Report 95-002 Incorrect Application of Static Shift to Pressurizer Level Channel LT-0467 ,

Pursuant to 10CFR50.73, Houston Lighting & Power Company submits the attached revision to Unit 2 Licensee Event Report 95-002 regarding inadequate calibration of a pressurizer level channel. This event did not have an adverse effect on the health and safety of the public but clearly does not meet the standards for expected operational performance.

The purpose of this revision is to change the date of a commitment contained within this Licensee Event Report. The action committed to revising the scaling database to add a method of monitoring static shift in differential pressure transmitters. Due to a change in priorities and the resultant revision to the implementation schedule for the scaling database, this corrective action will not be completed by the expected date of May 31,1995. The new date for this action will now be December 15, 1995. The date coincides with the revised database completion schedule. Changes are indicated by revision bars.

If you should have any questions on this matter, please contact Mr. J. M. Pinzon at (512) 972-8027 or me at (512) 972-8664. O M^
