1. INTRODUCTION This report is provided to facilitate review of Reference 1.

The report contains a summary of typical data base constants for Arkansas Nuclear One Unit 2 (ANO-2) Cycle 5 associated with the Reference 1 CPC methodology changes. These values have been extracted from the Reference 2 data base listing. The CPC algorithms for ANO-2 Cycle 5 are identical to those being reviewed for San Onofre Nuclear Generating Station Units 2 and 3 (Ref. 3).

The methodology used for generating these constants is the same as used for San Onofre Nuclear Generating Station Units 2 and 3 (Reference 4).
