By letter dated ' April 16, 1986, Georgia Power Company requested authorization to utilize subarticle NC-3600 of the Winters 1981 Addenda to the 1980 Edition of the ASME Section III Code for Class 2 piping stress analysis and subarticle ND-3600 of the Sumer 1984 Addenda to the 1983 Edition of the ASME Section III Code for Class 3 piping stress analysis for Vogtle, Units 1 and 2.- The letter stated that the use of these later addenda will be limited to small bore piping in the. reconciliation process required by IE Bulletin 79-14. The material, fabrication, examination, and overpressure protection requirements of Articles-NC/ND 2000, 4000, 5000, and 7000 and the balance of Article NC/ND

3000 in the Code of Record for Vogtle (the ASME Boiler and Pressure Vessel Code,1974 Edition with the Sumer 1975 Addenda) will be met.

.@ich Georgia Power Company is requesting to use was issued by the ASME in

part to revise previous design requirer.ents for ASME Class 2 and 3 piping.

Equa?.fon :(9) in NC/ND 3650 was revised to include stress indices to define the u . primary stress ccmponents and to provide a limiting stress in terms of yield strength. References 1 and 2 provide a detailed discussion of the technical 7

bases for these revisions. The staff's approval of these changes is contained 8608210262 DR 860818 ADUCK 05000424 PDR
