TR-066 Rev. 15 Page 3 of 11 INTRODUCTION Generic Letter 88-16 provides guidance for Technical Specification Changes conceming cycle-specific limits. The generic letter provides a vehicle for the removal of cycle specific parameters from the Technical Specifications 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 COLR has been prepared in accordance with the requirements of OC Technical Specification 6.9.1 .f. The Cycle 19 fuel/core operating limits were generated using the NRC-approved codes and methodologies identified in Reference 9. The information in this report is taken from references 11 through 14.

For each GE fuel design, the APLHGR limits provided in the COLR for operation with less than five loops are calculated to be the same as the f ive-loop limits at all exposure levels provided a non-operating loop is not an ISOLATED RECIRCULATION LOOP. If a non-operating loop is ISOLATED (both the suction and discharge valves are in the closed position as defined in References 6 and 14), then a 0.98 MAPHLGR multiplier must be applied at all exposure levels. Only one ISOLATED non-operating loop is permitted. Requirements for operation with recirculation loops out-of-service are provided in Technical Specification 3.3.F.2.

The LLHGR limits are implemented on a fuel rod exposure dependent basis. Figure 7 shows the maximum value of the LLHGR limit. The exposure dependent LLHGR values are contained reference 13 for the GE9B fuel, and in reference 12 for the GE1 I fuel.

The CPR limits in Figure 5 are differentiated based on the number of recirculation loops in service; one set of limits applies to the condition of five or four loops in service, while the other set applies to the condition of three loops in service. Cycle exposure dependent limits are provided for each condition. The limits cover operation at any point in the cycle with increased core flow up to 67.5 Mlblhr, feedwater temperature reduction of up to 105 F, and operation in the extended load line limit analysis (ELLLA) region.

During power operation thermal marg ins should be maintained within the specified limits. If at any time during power operation it is determined by normal surveillance that the limiting value forAPLHGR (Figures 1, 2, 3 and 4), LLHGR (Fig ure 7) or CPR (Figure

5) is being exceeded, action shall be initiated to restore operation to w ithin the prescribed limits as specified in Technical Specification Section 3.10.

Notes:

I (1) Umit applies in the cycle exposure range from beginning of cycle (BOC) until 2205 MWD/MT prior to end of rated (EOR). EOR is defined as the cycle exposure point where all rods out at rated power and flow occurs with all feedwater heaters in service.

l (2) Limit applies in the cycle exposure range from 2205 MWD/MT prior to EOR to extended end of cycle (EEOC). EEOC includes cycle extension options used beyond EOR (increased core flow, feedwater temperature reduction, and coastdown).
