2 The limiting RT PTS value for the axially oriented welds and plates is 120°F, which corresponds to the Lower Shell Plate R2708-3. Note that the Lower Shell Plate R2708-1 resulted in a higher RT PTS value of 141°F when the surveillance data was not used; however, the Lower Shell Plate R2708-1 RT PTS value is 100°F when the credible surveillance data was used. Thus, taking credit for the Lower Shell Plate R2708-1 credible surveillance data, the limiting material of the axially oriented welds and plates is the Lower Shell Plate R2708-3.}}
