TR# 066 TITLE oyster Creek Cycle 15 Core Operating Limits Report REV CUMMARY OF CHANGE APPROVAL DATE 1 Technical Specification references were added 7/11/90 to each Figure.

2 Correction to several typographical errors 11/14/90 were made.

References to the Figures were provided in the thermal margins discussion in the introduction.

Dates and revision numbers of various references were provided.

3 Revise document to reflect the cycle 13 design and safety analysis results. APLHGR limits (Figures 8 and 9) for two new fuel designs were added. Also the MCPR limit (Figure 10) changed from 1.51 to 1.48.

4 Revise document to reflect the Cycle 14 design and safety analysis results. MAPLHGR limits for ENCVB, GE-239, tr-265H and GE-299ZA fuel designs were removed. MCPR limit changed from 1.48 to 1.47. LLHGR limit for ENCVB fuel was removed.

5 Mid-Cycle 14 revision to the MCPR operating limit. The limit changed from a 1.47 to a 1.51 based on a re-analysis of EOC14 conditions.

6 Revise document to reflect the Cycle 15 design and safety analysis results. APLHGR and LLHGR limits for two new GE9 fuel designs (

f,j/f[f Y were added. Also, the MCPR limit changed from 1.51 to 1.50.

TR 066 Rev. 6 Page 2 of 11 INTRODUCTION j Generic Letter 88-16 provides guidance for Technical Specification changes concerning cycle-specific limits. The generic letter provides a vehicle for the removal of cycle specific parameters from the Technical Specification and the maintenance of these values within a Core Operating Limits Report (COLR). The Technical Specification modification also establishes reporting requirements and includes definitions supporting the proposed changes. The COLR, including mid-cycle revisions, will be provided for each reload cycle.

This Core Operating Limits Report (COLR) has been prepared in accordance with the requirements of OC Technical Specification 6.9.lf. The information in this report was reviewed and approved for use at Oyster Creek by means of the Cycle 15 Reload Information and Safety Analysis Report (TR-97-rev 0) dated August 1994.

The Cycle 15 fuel / core operating limits were generated using the NRC approved codes and methodologies identified in References 1 through 8.

For each GE fuel design the APLHGR limits provided in the COLR for four-loop operation are calculated to be the same as the five-loop limits at all exposure levels provided the idle loop is unisolated. If the idle loop has both its suction and discharge valves closed the loop is isolated as defined in Reference C and a 0.98 MAPLHGR multiplier must be applied at all exposure levels.

Requirements for operation with an idle loop are provided in Technical Specification 3.3.F.

During power operation thermal margins should be maintained within the specified limits. If at any time during power operation it is determined by normal surveillance that the limiting value for APLHGR (Figures 1-5), LLHGR (Figure 8) or CPR (Figures 6 and 7) is being exceeded action shall be initiated to restore operation to within the prescribed limits as specified in Technical Specification Section 3.10.
