Dear Mr. Purple:

SUPPLEMENTAL INFORMATION TO PROPOSED TECHNICAL SPECIFICATIONS CHANGE NO. 29 SUBMITTED PURSUANT TO 10 CFR 50.46, . SURRY POWER STATION, UNITS NO~

  • 1 & 2 On June 6, 1975, pursuant to 10 CFR 50.46, we submitted an ECCS evaluation along with associated proposed technical specifications for Surry Power Station Units No. 1 and 2.

On this same day, representatives from Vepco and the Regulatory staff met to discuss the power distribution limits used in our ECCS evaluation and delineated in the proposed technical specifications. In compliance with a request made by the staff, the following attachments are presented as further justification for the proposed power ~istribution limits. Please note that the attached material contains information that is proprietary to the Westinghouse Electric Corporation. The proprietary information has been marked by means of brackets. The basis for marking the material proprietary is identified by marginal notes referring to the standards in Section 8 of the affidavit of R. A. Wiesemann of record "In the Matter of Acceptance Criteria for Emergency Core Cooling Systems for Light Water Cooled Nuclear Power Reactors (Docket No. RM-50-1)" at transcript pages 3706 through 3710 (February 24, 1972). Due to the proprietary nature of this material which was obtained at considerable expense to the Westinghouse Electric Corporation and the release of which would seriously affect their competitive position, we request this information to be withheld from public disclosure in accordance with the Rules of Practice, 10 CFR 2.790, and that the information presented therein be safeguarded in accordance with 10 CFR 2.903. We believe that withholding this information will not adversely affect the public interest. r_~ r::; ') I C.J -.., ~~ l. (2)}}
