-Mr. James R.' Miller 03/18/85 The respective CPC algorithms for ANO-2 Cycle 5 and the methodology used to generate the typical data base constants for AN0-2 Cycle 5 are identical to those reviewed by the NRC for San Onofre Nuclear Generating Station Units 2 cycle 2.
Due to the proprietary nature of the attached material, CE has requested that certain portions of these documents be withheld from public disclosure.
To accommodate this request five copies of both the proprietary (copies numbered 01-05) and nonproprietary versions are attached. An affidavit in support of.this determination is also provided.
