Dear Mr. Grier:

This letter is in response to your November 8, 1979 letter which for-warded Revision 2 to IE Bulletin No. 79-02. This revision relates to pipe support base plate designs using concrete expansion anchor bolts associated with Seismic Category I piping systems at the Indian Point Unit No. 2 plant.

In our review of Seismic Category I piping supports using concrete expansion anchor bolts, all supports, including structural steel members (angle or channel) , were considered. The adequacy of these supports has been verified and was reported in our submittal to the Com-mission dated September 17, 1979. It should be further noted that no Seismic Category I piping supports are attached to concrete block walls at the Indian Point Unit No. 2 plant.

Should you or your staff have any questions, we would be pleased to discuss them with you.

Very truly yours,

/ // C /r William J. Cahill, Jr.
