Dear Sir:
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 (PGE-1020). 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 greater chan 1 percent. Nor do the items involve weight addi-tions which may result in an increase of greater than 1 percent of the calculated lateral forces in any major shear wall.
Until the license is amended to allow modification of the Control Build-ing, we will continue to keep you, the Licensing Board and other parties informed of work associated with those modifications. We will continue to keep you informed of any activities at Trojan which involve changes greater than 1 percent as described above.
Sincerely, y
