Arizona Public Service Company P.O. SOX 21666 ~ PHOENIX. ARIZONA 65036 April 15, 1983 ANPP-23510 WFQ/RJP Director of Nuclear Reactor Regulation Attention: Mr. George Knighton, Chief Licensing Branch No. 3 Division of Licensing U. S. Nuclear Regulatory Commission Washington, D. C. 20555

Subject:

Palo Verde Nuclear Generating Station (PVNGS) Units 1, 2 and 3 Docket.Nos. STN-50-528/529/530 File: 83-056-026; G.l.01.10

Reference:

Letter from E. E. Van Brunt, Jr., APS, to H. R. Denton, NRC, dated March 6, 1981.

Dear Mr. Knighton:

The referenced letter provided responses to open items from the PVNGS Auxiliary Feedwater System Independent Design Review, which was held in Phoenix on August 21 and 22, 1981.

Page 2 of the attachment to the Referenced letter states that check valve SG-V044 is being relocated from the Train B pump room to the Train A turbine-driven Auxiliary Feedwater pump room.

We have since evaluated this steam line in accordance with the criteria of Branch Technical Position -(BTP) MEB 3-1, B.2.C, and found that the pipe stresses do not exceed the 0.4(1.2Sht+SA) recommendation at any point in the Train B motor-driven Auxiliary 'Feedwater pump room. We have also evaluated this pipe in accordance with Appendix A of BTP APCSB3-1 and do not consider it to be a high-energy or moderate-energy line.

Based on these evaluations the necessary requirements are met without moving this check valve. Therefore, we are changing our previous commitment, and the present design will not be changed.

Very truly your 8304190507 830415 E. E. Van Brunt, Jr.
