so -s.3 Apg 2 91977 Ceneral Electric Company ATTN: Dr. Glenn G. Shentood Manager, Safety & Licensing 175 Curtner Avenue San Jose California 95125 Gentlemen:

During the past two-year period, a number of reactor facility licensees using GE systens filed proprietary docunents relating to the emergency core cooling system requirements of Appendix K to 10 CFR part 50 and requested that they be withheld from public disclosure pursuant to Section 2.790 of 10 CFR Part 2. Cnclosed is a description of each of the proprietary documents, the nenes of the licensees filing them the date on which they were transmitted to the Coninission, and the facilities involved.

We have reviewed the justifications provided and the proprietary infor-mation contained in the documents on the enclosed list and concluded that there is not sufficient justification for our withholding this inforrnation from public disclosure. The basis for this conclusion is that we feel it would be highly unlikely, if not inpossibic, for General Electric competitors to utilize the results of the calculations relating to the requirements specifidd in Appendix K to 10 CFR part 50 to qualify their own design models since:

1. developing a correlatien from the results of the analysis on a given plant design requires knowledge of many other parameters .

which could generally not be available to the General Electric competitors; and

2. any such correlation used as a basis for ECCS calculations would have to be based on sufficient experir.cntal data to justify its adequacy.

.. n General Electric Company -2' APR 29 D7 Therefore, based on your supporting infortation, we have detemined, in accordance with 12.790 of the Commission's regulations in effect at the time your requests were made, that the ECCS infonnation identified on the enclosed list, and requested to be withheld, is not proprietary.

Furthemore, withholding of the ECCS information in this situation is not in the public interest since there exists a strong need for the public to be fully apprised as to the bases for the Commission's licensing actions.

Accordingly, thirty days from the date of this letter, the documents will be placed in the Public Document Room at 1717 H Street, N. W.,

Washington, D. C., and in the various local public document rooms f(t the involved facilities. If within thirty days of this letter you request withdrawal of the listed documents, they will not be placed in the public document rooms. However, should you withdraw these documents you should be aware that the infomation contained therein was used in various licensing actions and that the Commission would consider its absence from the record to greatly impair the understanding of your ECCS analysis.

A copy of a letter on this matter being sent to each licensee involved is also enclosed.

Sincerely.
