y Gentlemen:
Attached to this letter is a list of Requests for Design Changes (ROCS) associated with the modification program described in the Report on Design Modifications for the Trojan Control Building (PGZ-1020). These items are modifications involving piping supports necessary to qualify piping systems for res;onse spectra developed in accordance with PGE-1020, appendiz 3.
The items on this list will not individually or collectively with other nodifications reduce the shear capacity of any sajor shear wall by greater than 1 percent. Nor do the items involve weight addi-ticas which may result in an increase of greater than 1 percent of the calculated lateral forces in any =ajor shear wall.
The Licensee will continue to keep the Board informed of activities at Trojan as described at the March 30, 1979 Prehearing Ccnference (Tr. 3204-05).
Sincerely,
