Dear Mr. Engelken:

Subject:

Docket Nos. 50-361 and 50-362 San Onofre Nuclear Generating Station, Units 2 and 3 By letter to your office dated May 18, 1931 we trans-mitted a final report h accordance with 10CFR50.55(e) regard-ing noncompliance with ASME Code NCA-3867.4a on chemical analysis verification of material used for manufacture of ASME Code bolts with nominal diameter exceeding one inch. That report stated that aSME Code Case N242 would be invoked by the Project for these bolts.

The purpose of this letter is to advise you that Code Case N-310, which deals specifically with bolting materials and which was confirmed by publication June,1981, will-be in-voked instead of Code Case N-242.

If you have any questions regarding this supplement l

to the report, we would be pleased to discuss them with you at l

your convenience.

Very trul yours, s
