Fluence values are based on the limiting beltline and extended beltline fluence.
2 The projected USE decreases were calculated in accordance with Position 1.2 of Regulatory Guide 1.99, Revision 2, and were conservatively taken from the base metal 0.20 % copper line in Figure 2 of the Reg. Guide.

Fluence values are based on the limiting beltline and extended beltline fluence.
2 The limiting RTPTS 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 RTPTS 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.
