Page 6 of 24 3.0 General Information The purpose of this revision is to provide the Core Operating Limits for Hope Creek Generating Station Unit 1 Cycle 17 / Rel oad 16 operation. This report provides information relative to OPRM setpoints and ba ckup stability regions, 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 re ferences to the most recent revision of the implemented approved methodology.

These operating limit values have been determined using NRC approved methods contained in GESTAR-II (Reference 1) and NEDO-32465-A Reactor Stability Detect and Suppress Solutions Licensing Basis Methodol ogy for Reload Applications (Reference 2). These operating limit values also include limitations wher e required by the NRC Safety Evaluation Report for Hope Creek License Amendment Nu mber 174, 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). In addition, the LHGR limits contained wit hin are based upon the GE Report, GE14 Compliance with Amendment 22 of NEDE

-24011-P-A (GESTAR II), NEDC-32868P, Revision 3, April 2009 (Reference 5). Re vision 3 of the GE14 Compliance report

updates the report to include a specific LHGR limit curve to be used by plants referencing NEDC-33173P.

The following sections contain operating limit values for both the GE14 fuel design and the GE14i Isotope Test Assemblies (GE14i ITAs

). The limits for the GE14i ITAs were determined using the methods and limitations described in the NRC Safety Evaluation Report for Hope Creek Licens e Amendment Number 184 (Ref erence 9). The operating limit values apply to both GE14 and GE14i ITAs, unless specific values are provided for

the GE14i ITAs. The limitations and penalties for the GE14 fuel design discussed in the previous paragraph also apply to the GE14i ITAs.

The method of calculating core average scram speed, , is provided in Option B Licensing Basis & Cycle-I ndependent Transient Evaluation for Implementation of the Technical Specification Im provement 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 4 of this document. Hope Creek Technical Specification 6.9.1.9 also requires that this report, in cluding any mid-cycle revisions, shall be provided upon issuance to the NRC.

COLR HOPE CREEK 1 Rev 4 (Cycle 17)

Page 7 of 24 This document is specific to Hope Creek G enerating Station Unit 1 Cycle 17 Reload 16 and shall not be applicable to any other core or cycle design. This report is applicable for Cycle 17 operating from the date of issuance through the end of cycle including consideration of a power coastdown to a co re thermal power that shall not go below 40% rated core thermal power. End of fu ll power capability is reached when 100%

rated power can no longer be maintained by in creasing core flow (up to 105% of rated core flow), at allowable rated feedwater temperatures, in the all-rods-out configuration.

Operation beyond the end of full power cap ability is defined as power coastdown operation which includes an operating assu mption 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-II for determining the operating limit LCO values described above).

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 lim its to the values specified in Table 4.1-1 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 4.1-1.

Page 10 of 24 4.2 Minimum Critical Power Ratio LIMITING CONDITION FOR OPERATION The MINIMUM CRITICAL POWER RATIO (MCPR) shall be equal to or greater than the MCPR limit computed from the following steps:

1. Determine as defined in Appendix A.

NOTE The SLO operating condition MCPR values in Tables 4.2-1, 4.2-2, 4.2-4, and 4.2-5 implement the increase in the MCPR Safe ty Limit to meet the requirements of Technical Specification 3.4.1.1 ACTION statement a.1.c.

2. Linearly interpolate a MC PR value as a function of from the MCPR value at =0 and MCPR value at =1 as specified in Table 4.2-1 and Table 4.2-2 for the appropriate condition. R epeat for each fuel type. 3. For the power dependent MCPR adjustment, when thermal power is 24% rated core thermal power, determine a K p value by linearly interpolating a K p value as a function of core rated thermal power from Table 4.2-3. Multiply the MCPR value obtained from Step 2 by the K p value to determine the power dependent MCPR limit for each fuel type.

When core thermal power is < 24% rat ed thermal power, no thermal limits are required. 4. For the flow dependent MCPR adjus tment, determine the appropriate flow dependent MCPR limit by linearly inter polating between the MCPR limits as a function of rated core flow using the in formation in Table 4.2-4 (GE14) and Table 4.2-5 (GE14i ITAs). 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 fu nction of core average scram speed (), 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 de fined by Hope Creek Technica l 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.
