1. In Table 3, Details of TWCF Calculation - ANO Unit 2 at 48 Effective Full Power Years (EFPY), input values are given for Cu, Ni, and fluence for each beltline material. These values are not all consistent with Nuclear Regulatory Commission (NRC) records. The Cu and Ni values are consistent with Arkansas Nuclear One, Unit 2 (ANO-2) License Renewal Application (LRA), Agencywide Documents Access and Management System, (ADAMS), Accession No. ML032890506, but were not consistent with Safety Analysis Report (SAR), Amendment No. 19. Fluence values are not consistent with the LRA or

the SAR. Please identify a docketed and reviewed reference containing these values, or provide a technical basis for the change from previous values. If any input values are changed, please provide the appropriate revised calculations.

2. Table 2, Additional Information Pertaining to Reactor Vessel Inspection - ANO-2, states that ANO-2 is bounded by 13 heatups/cooldowns per year. Please cite the plant design basis for heatup/cooldowns per year.
