Ilouston Lighting & Power Company Mr Robert Martin Page ST-HL-AE-1246 2.
The equation for computation of the sheer stress area was revised to make it consistent with the requirements of ANSI Bl.l.
3.
The ratio of sheer strength to tensile strength for bolt material has been reduced from 9.67 to B.5.
4.
The required factor of safety for both A-36 and A-193 anchor bolts is presented.
5.
Our submittals of August 1, 1984 and January 18, 1985 provided Phase II activity summaries and Revision 1 incorporates that material as appropriate.
6.
The results of a thread remeasurement program by Bechtel initiated in July, 1984 are incorporated to demonstrate (1) the reliability of the previous B&R measurements and (2) the adequacy of using major diameter measurements (in the absence of specific pitch diameter measurements) to assess the field fabricated threads.
7.
The responses to NRC questions in Section 4.0 have been updated per the reasons noted.
8.
Minor editorial corrections.
If you should have any questions concerning this matter, please contact Mr Michael E Powell at (713) 993-1328.
Very truly yours, J H Goldberg Group Vice-President, Nuclear MEP:JHG/aks
