1229-41st Street los Alamos, New Mexico 67544 Gentlemen:
Attached to this letter is a list of Requests for Design Changes (RDCs) associated with the modification program described in the Report on Design Modifications for the Trojan Control Building (P2-iO20). These items are modifications involving piping supports necessary to qualify
~
piping systems for response spectra developed in accordance with PGE-1020, Appendix B.
The items on this list will not individually or collectively with other modifications reduce the shear capacity of any major shear wall by greater than 1 percent. Nor do the items involve weight additions which may result in an increase of greater than 1 percent of the calcu-laced lateral forces in any major shear wall.
The Licensee will continue to keep the Board informed of activities at Trojan as described at the March 30, 1979 Prehearing Conference (Tr. 3204-05).
Sincerely,
\\
