Main Steamline Break Analysis for Revised Moderator Density Coefficients" (Proprietary), dated April, 1992.
This report is provided to support the NRC review of our referenced amendment application.
The amendment application requested changes to SONGS 1 Technical Specification limits for the end-of cycle Moderator Temperature Coefficient, safety injection line minimum boron concentration, and shutdown margin.
Also enclosed are three copies of WCAP-13347, "San Onofre Nuclear Generating Station - Unit 1 (SONGS-1) Main Steamline Break Analysis for Revised Moderator Density Coefficients" (Non-Proprietary); Proprietary Information Notice; Copyright Notice; and a Westinghouse authorization letter, CAW-92-305, and accompanying affidavit.
As WCAP-13346 contains information proprietary to Westinghouse Electric Corporation, it is supported by an affidavit signed by Westinghouse, the owner of the information. The affidavit sets forth the basis on which the information may be withheld from public disclosure by the Commission and addresses with specificity the considerations listed in paragraph (b)(4) of Section 2.790 of the Commission's regulations.
Accordingly, it is respectfully requested that the information which is proprietary to Westinghouse be withheld from public disclosure in accordance with 10 CFR Section 2.790 of the Commission's regulations.
