VIRGINIA ELECTRIC AND POWER COMPANY RICHMOND., VIRGINIA 23261 R. H. L:1,:ASBURO VxcE PRESIDENT Nuc:r..EAll 0PEBATI0NS May 10, 1982 Mr. Harold R. Denton, Director Office of Nuclear Reactor Regulation Attn:

Mr. Steven A. Varga, Chief Operating Reactors Branch No. 1 Division of Licensing U. S. Nuclear Regulatory Commission Washington, D. C.

Gentlemen:

Serial No. 283 NO/GSS:acm Docket Nos. 50-280 50-281 License Nos. DPR-32 DPR-37 AMENDMENT TO OPERATING LICENSES DPR-32 AND DPR-37 SURRY POWER STATION UNITS NO. 1 AND NO. 2 PROPOSED TECHNICAL SPECIFICATION CHANGE Pursuant to 10 CFR 50.90, the Virginia Electric and Power Company requests an amendment, in the form of changes to the Technical Specifications, to Operating License DPR-32 and DPR-37 for the Surry Power Station, Units No. 1 and No. 2.

The proposed changes are enclosed.

This request is to revise the Surry Technical Specifications to limit control rod misalignment to no more than +/-12 steps indicated positions.

This change generally agrees with the Standard Technical Specification and will eliminate any ambiquity in interpreting the requirement to maintain the control rod positions with in +/-12 steps.

As per the NRC letter of October 29, 1979 Vepco was notified that the present wording of the Surry Power Station Technical Specification concerning control rod alignment does not adequately address uncertainties in the individual control rod position indication.

Although Westinghouse has performed a safety analysis for control rod misalignment up to 24 steps, the analog control rod position indication system has an uncertainty of 12 steps.

Therefore, the maximum allowable indicated misalignment of control rod position is the difference between 24 steps and 12 steps, which is 12 steps.

The Standard Technical Specification addresses a maximum indicated misalignment of 12 steps and the Surry Technical Specifications are being revised accordingly.

Also, attached is the Technical Specification typographical error from 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
