1.0 Core Operating Umits Core operating limits for CR3 are established and documented in this CORE OPERATING LIMITS REPORT for Cycle 8 for the following:

3.1.3.6 Regulating Rod Insertion Umits 3.1.3.7 Rod Program 3.1.3.9 Axial Power Sha ping Rod Insertion Limits 3.2.1 AX1AL POWER IMBALANCE 3.2.4 QUADRANT POWER TILT ne analytical methods used to determine the core operating, limits addressed by the individual Technical Specifications shall be those previously reviewed 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 1977
3) BAW 10117P A," Babcock & Wilcox Version of PDQ User's Manual",

January 1977

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

December 1979

5) BAW-10124A,"F1.AME 3 - A Three Dimensional Nodal Code for Calculating Core Reactivity and Power Distributions", August 1976
6) BAW 10125A," Verification of'Itree Dimensional FLAME 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) The methodology for Rod Program received NRC approval in the Safety Evaluation Repert dated January 31,1990.

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

fuel thermal mechanical limits, core thermal hydraulic limits, ECCS limits, 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 su lements thereto, shall be provided upon issuance for each reload cycle to the C Document Control Desk with copies to the Regional Administrator and the Resident Inspector.
