1.0 INTRODUCTION

This report provides the cycle-specific limits for operation of the Pilgrim Nuclear Power Station (PNPS) during Cycle 20. In this report, Cycle 20 will be referred to as the present cycle . Although this report is not a part of the PNPS Technical Specifications, the Technical Specifications refer to this report for the applicable values of the following fuel-related parameters: Reference Technical Specification APRM Flux Scram Trip Setting (Run Mode) Table 3.1.1 APRM Rod Block Trip Setting (Run Mode) Table 3.2.C-2 Rod Block Monitor Trip Setting Table 3.2.C-2 Average Planar Linear Heat Generation Rate 3.11.A Linear Heat Generation Rate (LHGR) 3.11.B Minimum Critical Power Ratio (MCPR) 3.11.C Power/Flow Relationship 3.11.D Reactor Vessel Core Design 4.2 If any of the core operating limits in this report is exceeded, actions will be taken as defined in the referenced Technical Specification. The core operating limits in this report have been established for the present cycle using the NRG -approved methodology provided in the documents listed in Technical Specification 5.6.5. These limits are established such that the applicable limits of the plant safety analysis are met. 1.1 Stability Option 1-D Exclusion Region and Buffer Zone. The reactor shall not be intentionally operated within the Exclusion Region given in Figure 3.4-1 , for Two Loop Operation (TLO) and Figure 3.4-2 for Single Loop Operation (SLO). Immediate exit is required for inadvertent entry into the exclusion region. The reactor shall not be intentionally operated within the Buffer Zone given in Figure 3.4-1 for TLO and Figure 3.4-2 , for SLO when the on-line Stability Monitor is inoperable. Allowable values for APRM Scram and Rod Block trip set points are defined in Section 2. Revision 33 Cycle 20 COLR Page 6 of 38

PILGRIM NUCLEAR POWER STATION PNPS CORE OPERATING LIMITS REPORT RTYPE: G4.02 2.0 INSTRUMENTATION TRIP SETTINGS: 2.1 APRM Flux Scram Trip Setting (Run Mode) Ref. Technical Specifications: Table 3.1.1 APRM flux scram Allowable Trip Set points (ATSP) for TLO are shown on Figure 2.1-1. The scram set point curve clamps power at 120% of rated core thermal power. Formulae used to develop Figure 2.1 -1 are listed in Table 2.1-1. APRM flux scram Allowable Trip Set points (ATSP) for SLO are shown on Figure 2.1 -2. The scram set point curve clamps power at 120% of rated core thermal power. Formulae used to develop Figure 2.1-2 are listed in Table 2.1-2. In accordance with Technical Specification Table 3.1 .1, Note 15, for no combination of loop recirculation flow rate and core thermal power shall the APRM flux scram trip setting be allowed to exceed 120% of rated thermal power. Flow clamp feature is not used in Cycle 20 . Drive Flow to Core Flow relationship: APRM Trip settings use Drive flow to determine the power trip setting for both scrams and rod blocks, as the drive flow is a more reliable flow indication than core flow. The transient analysis uses the stability based trip settings based on Core Flow. Therefore , calibration of Drive flow vs. core flow is important to ensure that transient analysis assumptions for trip settings are implemented correctly. Drive Flow (W 0 ) normalization with core flow shall be done such that 100% Drive Flow with Two Loops corresponds to 100% Rated Core Flow of 69 M#/hr.

PILGRIM NUCLEAR POWER STATION PNPS CORE OPERATING LIMITS REPORT RTYPE: G4.02 2.2 APRM Rod Block Trip Setting (Run Mode) Reference Technical Specifications: Table 3.2.C-2, 3.1 .B .1 When the mode switch is in the RUN position, the Average Power Range Monitor (APRM) rod block Allowable Trip setting (ATSPRs) as a function of drive flow for Two Loop Operation shall be as given by Figure 2.2-1. The ATSPRs is clamped at 115% of rated core thennal power. Formulae that form the basis of the Figure 2.2-1 are listed in Table 2.2-1. The flow clamp feature is not used in Cycle 20. When the mode switch is in the RUN position, the Average Power Range Monitor (APRM) rod block Allowable Trip setting (ATSPRs) as a function of drive flow for Single Loop Operation shall be as given by Figure 2.2 -2. The A TSP Rs is clamped at 115% of rated core thennal power. Formulae that form the basis of the Figures 2.2-2 are listed in Table 2.2-2. The flow clamp feature is not used in Cycle 20. 2.3 Rod Block Monitor Trip Setting References : Technical Specification Table 3.2.C-2 , Ref. 5.15, Ref. 5.10 Table 4.5 (b) Allowable values for the power-dependent Rod Block Monitor trip set points shall be: Reactor Power, P Trip Set point (Allowable Value) (%of Rated) (% of Reference Level) p ~ 25.9 Not applicable (All RBM Trips Bypassed) 25 .9 < p ~ 62 .0 122 62.0 < p ~ 82 .0 118 82.0 < p 113 The allowable value for the RBM downscale trip set point shall be ~ 94.0% of the reference level. The RBM downscale trip is bypassed for reactor power ~ 25 .9% of rated (Technical Specification Table 3.2.C-1 , Note 5). The most limiting Analytical Value of Rod Block set point of 117% is justified as the Rod Withdrawal Error is expected to reduce MCPR by 0.28 if this set point is used . Since the minimum OLMCPR value is 1.46, a reduction of 0.28 in MCPR, starting with operation at OLMCPR, is expected to lower MCPR to 1.18. This is substantially above the Safety Limit MCPR of 1.08 . Allowable value of the HTSP is set at 113 % to provide add itional conservatism to account for uncertainties. Table 4-5(b) of Reference 5.10 with a more restrictive OLMCPR of 1.35 was used to detennine the RBM set points with margin. Cycle 20 COLR Revision 33 Page 12 of 38

PILGRIM NUCLEAR POWER STA TION PNPS CORE OPERATING LIMITS REPORT RTYPE: G4.02 3.0 CORE OPERATING LIMITS 3.1 Maximum Average Planar Linear Heat Generation Rate (MAPLHGR} Reference Techn ical Specification : 3.11 .A During power operation , MAPLHGR for each fuel type as a function of axial location and average planar exposure shall not exceed the appli cable limiting value . MAPLHGR limits for rated power and flow condi tions are given in Tables 3.1-1and3.1-2. Flow and power dependent multipliers used to be necessary only as a result applying pin based limit using lattice local peaking factors . Beginning with Cycle 20, the peak pin LHGR setdown is applied to the pin based LHGR limit. Therefore , there is no need for power and flow dependent multipliers on the MAPLHGR limit (Reference 5.10). Peak pin LHGR limits based on LOCA analysis are listed in Table 3.1-4. MAPLHGR for rated power and flow conditions for both fuel types, GE14 and GNF2 are presented in Figure 3.1-1 . MAPLHGR limits are based on ECCS-LOCA considerations. The MAPLHGR values for rated power and flow conditions are listed in Tables 3.1-1 for GE14 and 3.1 -2 for GNF2, which are obtained from the Supplemental Reload Licensing Report , Rev1 (Ref. 5.15). SRLR, Rev .1 corrected MAPLHGR tables for LOCA ana lytical error reports 2012-01 and 2011-02 to restore the Peak Clad Temperature to 2150 °F for both GE14 and GNF2 fuels . Beginning with Cycle 20 , peak pin LHGR (pLHGR) set down in the LOCA analysis is applied to the LHGR limit as it is a pin based limit. Therefore there is no need to composite the pLHGR with assumed Lattice Local Peaking factors to arrive at lattice based limits. Applying pLHGR to LHGR limit simplifies the MAPLHGR limits and makes these fuel type dependent, rather than lattice dependent. Licensing basis PCT based on the MAPLHGR Limits in this report for both fuel types , GE14 and GNF2 is 2150 °F (Ref. 5.15). All PCT determination errors reported under 10CFR50.46 up to 12/31 /2012 have been accounted for. Pbypass is the power level below which more restrictive thermal limits are applied , as the Turbine Stop Valve closure and Turbine Control Valve fast closure scrams are assumed to be bypassed . It can be set anywhere in the range from 32 .5% power to 45% power. Pbypass is currently set at 32 .5% power. If this setting is changed in the future , then the appropriate thermal limits can be determined using Tables 3.1-1 and 3.1-2 with Figure 3.1-3. When in Single Loop Operation , an SLO Multiplier of 0.8 for GE14 fuel and 0.89 (Table 3.1-3) for GNF2 fuel applies to the Rated MAPLHGR limit. At off rated conditions , MAPLHGR limit is the lower of the SLO Multiplier times the rated MAPLHGR limit, the MAPLHGRP or MAPLHGRF. Revision 33 Cycle 20 COLR Page 17 of 38

PILGRIM NUCLEAR POWER STATION PNPS CORE OPERATING LIMITS REPORT RTYPE: G4.02 3.2 Linear Heat Generation Rate (LHGR) Reference Technical Specification: 3.11.B When reactor power is greater than 25%, the LHGR of any rod in any fuel assembly at any axial location shall not exceed the rated power and rated core flow limits presented in Reference 5.17. Figure 3.2-1 represents LHGR curves for GE14 fuel. Proprietary detailed values for both GE14 and GNF2 fuels are in Reference 5.17. At other than rated power and rated flow conditions, the applicable limiting LHGR value for each fuel type is the smaller of the flow- and power-dependent LHGR limits, LHGRF and LHGRp. The flow-dependent LHGR limit, LHGRF. is the product of the LHGR flow factor, LHGRFACF, shown in Figure 3.2-2 and the LHGR for rated power and flow conditions in Reference 5.17. The power-dependent LHGR limit, LHGRp, is the product of the LHGR power factor, LHGRFACp, shown in Figure 3.2-3 and the LHGR for rated power and flow conditions in Reference 5.17. LHGR Curves in Figure 3.2-1 are representative curves for U02 fuel rods and Gd containing rods for GE14 Fuel. A Figure comparable to Figure 3.2-1 for GNF2 is not included because GNF has requested Entergy to protect this proprietary information. Gd containing fuel rods have different LHGR limits that are also exposure dependent. Reference 5.17 documents the detailed proprietary curves and values for both GE14 and GNF2 fuels. Reference 5.23 documents the GESTAR II compliance of GNF2 fuel, as amended. Amendment 33 to GESTAR II incorporated Prime T-M methods. Cycle 20 LHGR limits are based on using PRIME for U02 fuel rods and GESTR-M for Gd rods, as GESTR-M limits for Gd rods are more conservative. Pbypass is the power level below which more restrictive thermal limits are applied, as Turbine Stop Valve closure and Turbine Control Valve Fast Closure scrams are assumed to be bypassed. Pbypass can be set in anywhere in the range 32.5 to 45% core thermal power. Pbypass is currently set at 32.5% power. Revision 33 Cycle 20 COLR Page 22 of 38

PILGRIM NUCLEAR POWER STATION PNPS CORE OPERATING LIMITS REPORT RTYPE: G4.02 3.3 Minimum Critical Power Ratio (MCPR) Reference Technical Specification: 3.11 .C During power operation, the MCPR shall be greater than or equal to the Operating Limit MCPR (OLMCPR). The operating limit MCPR is the greater of the flow- and power-dependent MCPR operating limits, MCPRF and MCPRp. The flow-dependent MCPR operating limit, MCPRF . is provided in Figure 3.3-1. For power level less than Pbypass. the MCPRp is independent of the fuel type and can be directly read from Figure 3.3 -2, when Turbine Bypass is operable and from Figure 3.3-3, when Turbine Bypass is out of service . Above Psypa_ss. MCPRp is the product of the rated power and flow MCPR operating limit presented in Table 3.3-1, and the Kp factor presented in Figure 3.3-2, when Turbine Bypass is in service and from Figure 3.3-3, when Turbine Bypass is out of service. The rated power and flow MCPR operating limits presented in Tables 3.3-1 are functions of "'C . Both Figures 3.3-2 and 3.3-3 include normal and reduced feed water temperature operating modes . For SLO MCPRp and MCPRF are raised by 0 .03 compared to TLO values shown in Figures 3.3-2 and 3.3-3. The value of r in Table 3.3-1 shall be equal to 1.0, unless it is calculated from the results of the surveillance testing of Technica l Specification 4.3 .C . TS 4 .11 .C defines "'C . Pbypass is the power level below which more restrictive thermal limits are applied , as Turbine Stop Valve Closure and Turbine Control Valve Fast Closure scrams are assumed to be bypassed . Pbypass can be set anywhere in the range 32.5% to 45% core thermal power. Pbypass is currently set at 32.5% . Transient Analysis assumes that the transient initiates from opera ti on within the Feedwater temperature vs . Reactor Power band (Figure 3.3-4 ). Transient Analysis also assumes that the transient initiates from operation at a Reactor Pressure within the upper & lower limit curves defined by Figure 3.3-5 . If operating at 95% power and Reactor pressure between 1015 psig and the lower pressure band in Figure 3.3-5 , an OLMCPR penalty of 0.0 1 must be applied (Reference 5.22). To operate above the lower pressure curve (not including the flat portion of the curve at 1015 psig above 95% power) in Figure 3 .3-5 , there is no OLMCPR penalty.

PILGRIM NUCLEAR POWER STATION PNPS CORE OPERATING LIMITS REPORT RTYPE: G4.02 3.4 Power/Flow Relationship During Power Operation Reference Technical Specification: 3.11.D The Cycle 20 stability analysis does not credit the flow clamp feature of the FCTR cards. The dominance of Core Wide Oscillations was demonstrated without the use of the flow clamp. APRM Flux scram and Rod Block curves without the flow clamp are therefore applicable to Cycle 20. . The power/flow relationship shall not exceed the limiting values shown on the Power/Flow Operating Maps in Figures 3.4-1 when in Two Loop Operation and 3.4-2 when in Single Loop Operation. Cycle 20 operation is not fully analyzed for reduced feedwater temperature for issues other than thermal limits . The SRLR (Reference 5.15) contains only the thermal limit analysis results for reduced feed water temperature mode . The exclusion and the buffer regions shown in Figures 3.4-1 and 3.4-2 are based on Stability Solution 1-0 (references 5.4, 5.12 , 5.15 and 5.20). Cycle 20 Stability Analysis summarized in the SRLR (Reference 5.15, Section 15) utilizes ODYSY LTR (Reference 5.24) that removed the decay ratio adder of 0.15 .Figures 3.4-1 and 3.4-2 show APRM Scram and Rod Block lines using Allowable values as a function of Core Flow. Single Loop Analysis limits maximum Core Flow to 52% of Rated Core Flow and maximum Power to 65% of Rated due to SLO vessel internal vibration (Ref. 5.7, p. 1-2). Various lines on the Power to flow map are described in Ref. 5.14. Revision 33 Cycle 20 COLR Page 33 of 38

PILGRIM NUCLEAR POWER STATION PNPS CORE OPERATING LIMITS REPORT RTYPE : G4.02 4 .0 REACTOR VESSEL CORE DESIGN Reference Technical Specification: 4 .2 The reactor vessel core for the present cycle consists of 580 fuel assemblies of the types listed below. The core loading pattern (Ref. 5.15) for each type of fuel is shown for the present cycle in Figure 4.0-1. Core Loading Pattern differs from that in the SRLR (Reference 5.15) due to a minor rearrangement, accepted through a GESTAR II Assessment (Reference 5.15) for the purposes of reducing the impact of channel bow and NEXRAT.

ENCLOSURE 3 KGO-ENO-H K 1-17-081 Affidavit for Enclosure 1

Global Nuclear Fuel - Americas AFFIDAVIT I, Brian R. Moore, state as follows: (1) I am General Manager, Core & Fuel Engineering, Global Nuclear Fuel - Americas, LLC (GNF-A), and have been delegated the function of reviewing the information described in paragraph (2) which is sought to be withheld, and have been authorized to apply for its withholding. (2) The information sought to be withheld is contained in Enclosure 1 of GNF ' s letter, KGO-ENO-HKl-17-081 , Kimberly O'Connor (GNF) to Nela Szwarc (Entergy), entitled "Pilgrim Nuclear Power Station Cycle 20 Core Operating Limits Report (COLR) Revision 33 and Cycle 21 COLR Revision 34, 35, and 36 - Proprietary and Non-Proprietary Versions," July 28, 2017. GNF proprietary information in Enclosure I , which is entitled "Pilgrim Nuclear Power Station Cycle 20 Core Operating Limits Report, Revision 33 ," is identified by a dotted underline inside double square brackets. ((TbJ.~ .. ?.~n.t.~nf~..!?...f:l.D.

    ~~!'!!TIP.!~,~~_}_)) A " ((" marking at the beginning of a table, figure , or paragraph closed with a
    ")) marking at the end of the table, figure or paragraph is used to indicate that the entire content between the double brackets is proprietary. In each case, the superscript notation {3}

refers to Paragraph (3) of this affidavit, which provides the basis for the proprietary determination . (3) In making this application for withholding of proprietary information of which it is the owner or licensee, GNF-A relies upon the exemption from disclosure set forth in the Freedom of Information Act ("FOIA"), 5 USC Sec. 552(b)(4), and the Trade Secrets Act, 18 USC Sec. 1905 , and NRC regulations 10 CFR 9.l 7(a)(4), and 2.390(a)(4) for "trade secrets" (Exemption 4). The material for which exemption from disclosure is here sought also qualify under the narrower definition of "trade secret", within the meanings assigned to those terms for purposes of FOIA Exemption 4 in, respectively, Critical Mass Energy Project v. Nuclear Regulatory Commission, 975F2d87 l (DC Cir. 1992), and Public Citizen Health Research Group v. FDA, 704F2dl280 (DC Cir. 1983). (4) Some examples of categories of information which fit into the definition of proprietary information are :

a. Information that discloses a process, method, or apparatus, including supporting data and analyses, where prevention of its use by GNF-A's competitors without license from GNF-A constitutes a competitive economic advantage over other companies;
b. Information which, if used by a competitor, would reduce his expenditure of resources or improve his competitive position in the design, manufacture, ship~ent, installation, assurance of quality, or licensing of a similar product;
c. Information which reveals aspects of past, present, or future GNF-A customer-funded development plans and programs, resulting in potential products to GNF-A ;

KGO-ENO-HKl-17-081Enclosure1 Affidavit Page I of 3

d. Information which discloses patentable subject matter for which it may be desirable to obtain patent protection.

The information sought to be withheld is considered to be proprietary for the reasons set forth in paragraphs (4)a. and (4)b. above. (5) To address 10 CFR 2.390 (b) (4), the information sought to be withheld is being submitted to NRC in confidence. The information is of a sort customarily held in confidence by GNF-A, and is in fact so held . The information sought to be withheld has, to the best of my knowledge and belief, consistently been held in confidence by GNF-A, no public disclosure has been made, and it is not available in public sources. All disclosures to third parties including any required transmittals to NRC, have been made, or must be made, pursuant to regulatory provisions or proprietary agreements which provide for maintenance of the information in confidence. Its initial designation as proprietary information, and the subsequent steps taken to prevent its unauthorized disclosure, are as set forth in paragraphs (6) and (7) following. (6) Initial approval of proprietary treatment of a document is made by the manager of the originating component, the person most likely to be acquainted with the value and sensitivity of the information in relation to industry knowledge, or subject to the terms under which it was licensed to GNF-A . (7) The procedure for approval of external release of such a document typically requires review by the staff manager, project manager, principal scientist or other equivalent authority, by the manager of the cognizant marketing function (or his delegate), and by the Legal Operation, for technical content, competitive effect, and determination of the accuracy of the proprietary designation. Disclosures outside GNF-A are limited to regulatory bodies, customers, and potential customers, and their agents, suppliers, and licensees, and others with a legitimate need for the information, and then only in accordance with appropriate regulatory provisions or proprietary agreements. (8) The information identified in paragraph (2) is classified as proprietary because it contains details of GNF-A ' s fuel design and licensing methodology. The development of thi s methodology, along with the testing, development and approval was achieved at a significant cost to GNF-A. The development of the fuel design and licensing methodology along with the interpretation and application of the analytical results is derived from an extensive experience database that constitutes a major GNF-A asset. (9) Public disclosure of the information sought to be withheld is likely to cause substantial harm to GNF-A's competitive position and foreclose or reduce the availability of profit-making opportunities. The information is part of GNF-A's comprehensive BWR safety and technology base, and its commercial value extends beyond the original development cost. The value of the technology base goes beyond the extensive physical database and KGO-ENO-HK 1-17-081 Enclosure 1 Affidavit Page 2 of 3

analytical methodology and includes development of the expertise to determine and apply the appropriate evaluation process. In addition, the technology base includes the value derived from providing analyses done with NRC-approved methods . The research, development, engineering, analytical , and NRC review costs comprise a substantial investment of time and money by GNF-A. The precise value of the expertise to devise an evaluation process and apply the correct analytical methodology is difficult to quantify, but it clearly is substantial. GNF-A's competitive advantage will be lost if its competitors are able to use the results of the GNF-A experience to normalize or verify their own process or if they are able to claim an equivalent understanding by demonstrating that they can arrive at the same or similar conclusions. The value of this information to GNF-A would be lost if the information were disclosed to the public. Making such information available to competitors without their having been required to undertake a similar expenditure of resources would unfairly provide competitors with a windfall , and deprive GNF-A of the opportunity to exercise its competitive advantage to seek an adequate return on its large investment in developing and obtaining these very valuable analytical tools. I declare under penalty of perjury that the foregoing is true and correct. Executed on this 28th day of July 2017 . Brian R. Moore General Manager, Core & Fuel Engineering Global Nuclear Fuel - Americas, LLC 3901 Castle Hayne Road Wilmington, NC 28401 Brian.Moore@ge.com KGO-ENO-HKl-17-081 Enclosure l Affidavit Page 3 of 3 L}}
