APS to G.

W. Knighton,

NRC, dated May 2,

1983, (ANPP-23635).

Dear Mr. Knighton:

The Referenced (1) letter provided the Staff's comments concerning a proposed revision to the Palo.Verde FSAR relating to Component Classification (Section 3.2.2 and table 3.2-1) and the scope of augmented inservice inspec-tion (Section 3.6.2 and 6.6.8) which had been forwarded to the NRC per the Reference (2) letter.

The Staff's'comments stated that the proposed changes to the FSAR were, accept-able, with one exception.

With respect to the Chemical and Volume Control

System, the proposed classification change for components in the letdown loop of the system would not be acceptable since the classification would be below the level recommended by Regulatory Guide 1.26.

APS has reviewed this comment, and agrees to maintain the letdown loop classifications as indicated in the current revision of the FSAR.

Attached are marked up pages to the proposed classification changes from the previous submittal (Reference (2)).

If you have any further questions or comments concerning this matter, please contact me.

Very truly yours, 8309'070047 830830 A
