WASHINGTON, D. C. 20555 May 25, 1979 Docket No. 50-293 Mr. G. Carl Andognini M/C NUCLEAR Boston Edison Company 800 Boylston Street Boston, Massachusetts 02199
Dear Mr. Andognini:
This letter is submitted in response to your letters dated May 23, and 25, 1979 which provided documentation of the results of seismic piping stress reanalysis for Pilgrim Nuclear Power Statio'n Unit No.1 in connection with IE Bulletin 79-07.
Your submittal was also in response to the staff's request for information set forth in our meeting of May 18, 1979.
On the basis that the reanalysis was conducted using computer programs employing acceptable seismic response combinati>n techniques, and the acceptable results from the reanalyses, we conclude that the requirements set forth in IE Bulletin 79-07 will be adequately satisfied to allow resumption of operation on completion of the modifications identified in Attachment B to your May 23, letter, and as-built verification o., the recirculation system and the D main steam line. As-built verification on the other steam lines and branch lines and completion of code verifications will be required before your response to IE Bulletin 79-07 is considered finally complete.
A copy of our evaluation addressing this matter is enclosed.
Sincerel,
~7 b Thomas A. Ippolito, Chief Operating Reactors Branch #3 Division of Operating Reactors
