Dear Sir:
This letter supplements the information which was provided to you by our January 3, 1980 letter regarding the status of Shock 2 computer calculations which were performed for 6 inch and under piping for the Surry 1 and 2, Maine Yankee and J, A. FitzPatrick Projects.
The information contained herein addresses only 6 inch and under piping configurations that were not analyzed as branch piping (branches from piping greater than 6 inch in diameter) as a part of the Show-Cause Reanalysis effort.
Surry 1 and 2 Maine Yankee J.A.FitzPatrick The review of all available pre-1979 records disclosed no evidence that any Shock 2 computer calculations exist other than those which were reanalyzed as a part of the Show Cause reanalysis effort.
As previously reported, there are a number of Shock 2 computer calculations that were made for 6 inch and under piping.
All of these were reanalyzed as a part of the Show Cause reanalysis.
All of the 2~ to 6 inch piping identified in compliance with IE Bulletin 79-14 is being re-evaluated and/or reanalyzed with only one piping problem remaining to be completed.
We have verified that none of this piping was previously analyzed using the Shock 2 computer program.
Based on this information, we conclude that there are no outstanding Shock 2 computer program related questions for the piping discussed above.
