JUNE 1 1 1979 Docket No. 50-206 Mr. James H. Drake, Vice President Southern California Edison Company 2244 Walnut Grove Avenue Post Office Box 800 Rosemead, California 91770
Dear Mr. Drake:
SUBJECT:
INFORMATION COPY OF REQUEST FOR ADDITIONAL INFORMATION REGARDING-WESTINGHOUSE SMALL BREAK LOCA ANALYSIS As we discussed with you during our meeting on May 30, 1979, the NRC staff is evaluating certain aspects of the NRC licensing process in light of the Three Mile Island Unit 2 (TMI-2) accident of March 28, 1979. One of the aspects being addressed by the staff in its evaluation is the status of the models used in safety analyses, especially with regard to transients and small break LOCAs.
Enclosed is a copy of an NRC letter, dated June 4, 1979, requesting information from your nuclear steam supply vendor, the Westinghouse Electric Corporation, regarding small break LOCA analyses and analysis methods. This enclosure is provided for your information.
It is our understanding that you are participating in this effort as it applies to your licensed power plant through an owners group.
At some point in this effort we will require that you document the applicability of the results of these Westinghouse analyses to your plant. To that end, a copy of all correspondence to Westinghouse and the owners group on this matter will be provided to you and placed in our-files on your specific plant.
Please contact P. D. O'Reilly, the staff's assigned project manager for this matter, if you have any questions.
Sincerely, Original Signed By D. Ziemann, Chief Operating Reactors Branch #2 D'vision of Onerating Reactors
