Information Request, Auxiliary Feedwater Piping Systems San Onofre Nuclear Generating Station Unit 1 Per your letter dated September 28,
- 1981, I have enclosed (as listed in Attachment I) the majority of additional information required for your analysis.
Unfortunately, some of the information you requested is not available and,' therefore, will not be provided.
The information not provided is also listed in Attachment I.
Isometrics for the line numbers specified in items la, 1b, 1c, id, and 5 of your letter are provided when they are available. I have enclosed the related plan and section drawings from which isometrics can be developed if isometrics are not available.
In regards to Items 2 and 5 of your letter, the most efficient way to obtain the information you have requested, is for you to contact the suppliers directly.
The enclosed valve numbers should aid you in obtaining the desired descriptions.
The main stop val'e for the turbine is supplied by Westinghouse.
Finally, in reference to your question in Item 4, we confirm that those lines are supported.
If you have any questions on any of this information, please let me know.
Sincerely, O(
