OPERATING LIMITS REPORT for Cycle 8 for the following: ,

3.1.3.6 Regulating Rod Insertion Limits 3.1.3.7 Rod Program 3.1.3.9 Axial Power Shap ng Rod Insertion Limits 3.2.1 AXIAL POWER MBALANCE 3.2.4 QUADRANT POWER TILT The analytical methods used to determine the core operating limits addressed by the individual Technical Specifications shall be taose previously revlewed and approved by the NRC, specifically:

1) BAW-10122A Rev.1, " Normal Operating Controls", May 1984
2) BAW 10116A," Assembly Calculations and Fitted Nuclear Data", May 4 1977
3) BAW-10117P-A," Babcock & Wilcox Version of PDO User's Manual",

January 1977

4) BAW 10118A," Core Calculational Techniques and Procedures",

December 1979

5) BAW 10124A "FLAhE 3 - A Three-Dimensional Nodal Code for Calculating Core Reactivity and Power Distributions", August 1976
6) BAW-10125A," Verification of Three Dimensional FLAhE Code",

August 1976

7) BAW 10152A " NOODLE - A Multi Dimensional Two-Group Reactor Simulator", June 1985
8) BAW 10119," Power Peaking Nuclear Reliability Factors", June 1977
9) ne methodology for Rod Program received NRC approval in the Safety Evaluation Report dated January 31,1990.

The core operating limits shall be determined so that all applicable limits (e.g.,

fuel thermal mechanical limitr, core thermal hydraulic linuts, ECCS limits, I

nuclear limits such as shutdown margin, and transient and accident analysis limits) of the safety analysis are met.

The CORE OPERATING LIMITS REPORT, including any mid cycle revision or suoplements thereto, shall be provided upon issuance for each reload cycle to l the b RC Document Control Desk with copies to the Regional Administrator L and the Resident Inspector, i
