Page 5 of 26 COLR HOPE CREEK 1 Rev 14 {Cycle 22) 3.0 Generallnformation This revision of the Core Operating Limits Report provides the core operating limits for Hope Creek Generating Station Unit 1 Cycle 22 operation.

This report provides information relative to OPRM setpoints, backup stability protection regions, RBM setpoints, single recirculation loop operation, and core average scram speed. The power distribution limits presented here correspond to the core thermal limits for Average Planar Linear Heat Generation Rate (APLHGR), Minimum Critical Power Ratio (MCPR), and Linear Heat Generation Rate (LHGR). Finally, this report provides references to the most recent revision of the implemented approved methodology.

These operating limit values have been determined using NRC approved methods contained in GESTAR-11 (Reference 1). These operating limit values also include limitations where required by the NRC Safety Evaluation Report for Hope Creek License Amendment Number 17 4, Extended Power Uprate (Reference

3) for the use of GE Licensing Topical Report NEDC-33173P, Applicability of GE Methods to Expanded Operating Domains (Reference 4 ). The following sections contain operating limit values for both the GE14 fuel design and the GNF2 fuel design. The operating limit values apply to both GE14 and GNF2, unless specific values are provided for a fuel design. The method of calculating core average scram speed, -r, is provided in Option 8 Licensing Basis & Cycle-Independent Transient Evaluation for Implementation of the Technical Specification Improvement Program (TSIP) Scram Speed (Reference 8). These operating limits are established such that all applicable fuel thermal-mechanical, core thermal-hydraulic, ECCS, and nuclear limits such as shutdown margin, and transient and accident analysis limits are met. Various sections of the Hope Creek Technical Specifications reference this COLR. Those sections are listed in Section 5 of this document.

Hope Creek Technical Specification 6.9. 1 .9 also requires that this report, including any mid-cycle revisions, shall be provided upon issuance to the NRC. Page 6 of 26 COLR HOPE CREEK 1 Rev 14 (Cycle 22) 4.0 Precautions and Limitations This document is specific to Hope Creek Generating Station Unit 1 Cycle 22 and shall not be applicable to any other core or cycle design. Revision 14 of the COLR is applicable for Cycle 22 operating from the date of issuance through the end of cycle including consideration of reduced feedwater temperatures for FWHOOS or FFWTR, and a power coastdown to a core thermal power that shall not go below 40% rated core thermal power. End of full power capability is reached when 100% rated power can no longer be maintained by increasing core flow (up to 105% of rated core flow), at allowable feedwater temperatures, in the all-rods-out configuration.

The term out" excludes control rods that have been inserted to suppress fuelleakers, address cell friction performance, or other circumstances that would require control rod insertion to meet Technical Specification Operability requirements (Reference 9). Operation beyond the end of full power capability is defined as power coastdown operation which includes an operating assumption that vessel dome pressure will decrease during the power coastdown period as steam flow decreases (maintaining constant vessel dome pressure during the power coastdown period was not generically considered by GESTAR-11 for determining the operating limit LCO values described above). FWHOOS was evaluated for a final feedwater temperature reduction of up to 60°F from the design rated thermal power final feedwater temperature of 433.5°F (433.5°F -60°F = 373.5°F).

Therefore, Cycle 22 FWHOOS operation is limited to feedwater system configurations that result in a final feedwater temperature greater than or equal to 373.5°F at rated thermal power. FWHOOS operation and the associated limitations may be implemented any time during the operating cycle prior to cycle extension utilizing FFWTR. FFWTR was evaluated for a final feedwater temperature reduction of up to 86°F from the design rated thermal power final feedwater temperature of 433.5°F (433.5°F -86°F = 347.5°F).

Therefore, Cycle 22 FFWTR operation is limited to feedwater system configurations that result in a final feedwater temperature greater than or equal to 347.5°F at rated thermal power which is compliant with Renewed Facility Operating License No. NPF-57 License Condition 2.C.(11):

The facility shall not be operated with a rated thermal power feedwater temperature less than 331.5°F for the purpose of extending the normal fuel cycle. FFWTR operation and the associated limitations shall only be implemented for the purposes of cycle extension after rated thermal power cannot be maintained at 1 OQ%, rated total core flow in the all-rods-out configuration.

When the Technical Specification 3.4.1.1 Action Statement a.1.d is entered from that section's Limiting Condition for Operation, reduce the APLHGR limits to the values specified in Table 5.1-1 and Table 5.1-2 for single recirculation loop operation (SLO). Linear interpolation shall be used to determine APLHGR limits as a function of exposure for intermediate values in Table 5.1-1 and Table 5.1-2.

Determine 1: as defined in Appendix A. NOTE The SLO operating condition MCPR values in Tables 5.2-1, 5.2-2, and 5.2-4 implement the increase in the MCPR Safety Limit to meet the requirements of Technical Specification 3.4.1.1 Action Statement a.1.c. , 2. Linearly interpolate a MCPR value as a function of 1: from the MCPR value at 1:=0 and MCPR value at 1:=1 as specified in Table 5.2-1 and Table 5.2-2 for the appropriate condition.

Repeat for each fuel type. 3. For the power dependent MCPR adjustment, when thermal power 24o/o rated core thermal power, determine a Kp value by linearly interpolating a Kp value as a function of core rated thermal power from Table 5.2-3. Multiply the MCPR value obtained from Step 2 by the Kp value to determine the power dependent MCPR limit for each fuel type. When core thermal power is < 24% rated thermal power, no thermal limits are required.

4. For the flow dependent MCPR adjustment, determine the appropriate flow dependent MCPR limit by linearly interpolating between the MCPR limits as a function of rated core flow using the information in Table 5.2-4. 5. Choose the most limiting (highest value) of the power and flow dependent MCPR limits determined in Steps 3 and 4 as the value for the MCPR limit for the Limiting Condition for Operation for each fuel type. Note that the MCPR limit is a function of core average scram speed (1:), cycle exposure, core thermal power, total core flow, EOC-RPT operability, the number of reactor coolant recirculation loops in operation, and main turbine bypass operability.

EOC-RPT system operability is defined by Hope Creek Technical Specification 3.3.4.2. Reactor coolant recirculation loop operation is defined by Hope Creek Technical Specification 3.4.1.1. Main Turbine Bypass operability is defined by Hope Creek Technical Specification 3.7.7.

Determine the exposure dependent LHGR limit using linear interpolation between the table values in Appendix B. NOTE For two recirculation loop operation (TLO) utilize steps 1, 2, 3, and 6 to determine the LCO LHGR limits. When the Technical Specification 3.4.1.1 ACTION statement a.1.e is entered from that section's Limiting Condition for Operation (LCO), utilize steps 1, 4, 5, and 6 to determine the LCO LHGR limits for single recirculation loop operation (SLO). 2. For the power dependent LHGR adjustment for TLO, determine a LHGRFACp value by linearly interpolating a LHGRFACp value as a function of rated core thermal power from the TLO entries in Table 5.3-1. Multiply the LHGR values obtained from Step 1 by the LHGRFACp value to determine the power dependent LHGR limit. 3. For the flow dependent LHGR adjustment for TLO, determine a LHGRFACt value by linearly interpolating a LHGRFACf value as a function of rated core flow from the TLO entries in Table 5.3-2. Multiply the LHGR values obtained from Step 1 by the LHGRFACt value to determine the flow dependent LHGR limit. 4. For the power dependent LHGR adjustment for SLO, determine a LHGRFACp value by linearly interpolating a LHGRFACp value as a function of rated core thermal power from the SLO entries in Table 5.3-1. Multiply the LHGR values obtained from Step 1 by the LHGRFACp value to determine the power dependent LHGR limit. 5. For the flow dependent LHGR adjustment for SLO, determine a LHGRFACt value by linearly interpolating a LHGRFACt value as a function of rated core flow from Page 13 of 26 COLR HOPE CREEK 1 Rev 14 (Cycle 22) the SLO entries in Table 5.3-2. Multiply the LHGR values obtained from Step 1 by the LHGRFACt value to determine the flow dependent LHGR limit. 6. Choose the most limiting (lowest value) of the power and flow dependent LHGR limits determined in Steps 2 and 3 (TLO) or 4 and 5 (SLO) as the value for the LHGR limit for the Limiting Condition for Operation.

The ABSP region is conservatively constructed to encompass BSP Region 1 and generates an immediate automatic reactor scram upon entry. The ABSP region provided is applicable for Nominal, FWHOOS, and FFWTR conditions.
