1.0 INTRODUCTION

This report provides the cycle-specific limits for operation of the Pilgrim Nuclear Power Station (PNPS) during Cycle 18. In this report, Cycle 18 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 theapplicable 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 NRC-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 Figures 3.4-1, 3.4-2, and 3.4-3 for Two Loop Operation (TLO) and Figures 3.4-4 and 3.4-5 for Single Loop Operation (SLO), as applicable. Immediate exit is required for inadvertent entry into the exclusion region.

The reactor shall not be intentionally operated within the Buffer Zone given in Figures 3.4-1, 3.4-2, and 3.4-3 for TLO and Figures 3.4-4 and 3.4-5, as applicable, 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.

Cycle 18 COLR Revision 29 Page 6 of 59

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 The Cycle 18 stability analysis credited the flow clamp feature of the FCTR cards from BOC to 2,000 MWD/ST to ensure the dominance of Core Wide Oscillations. APRM Flux scram and Rod Block curves including the flow clamp have been developed for Cycle 18. These curves may be replaced with those that do not include the flow clamp after reaching a cycle exposure of 2,000 MWD/ST.

APRM flux scram Allowable Trip Set points (ATSP) for TLO with and without the flow clamp are shown on Figures 2.1-1 and 2.1-3, respectively. Both curves clamp power at 120% of rated core thermal power. Formulae used to develop Figures 2.1-1 and 2.1-3 are listed in Tables 2.1-1 and 2.1-3, respectively.

APRM flux scram Allowable Trip Set points (ATSP) for SLO with and without the flow clamp are shown on Figures 2.1-2 and 2.1-4, respectively. Both curves clamp power at 120% of rated core thermal power. Formulae used to develop Figures 2.1-2 and 2.1-4 nre listed in Tables 2.1-2 and 2.1-4, respectively.

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.

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 analysis calculates the stability based trip settings based on Core Flow.

Drive Flow (WD) 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.

,3.0 CORE OPERATING LIMITS 3.1 Maximum Average Planar Linear Heat Generation Rate (MAPLHGR)

Reference Technical 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 applicable limiting value. The applicable limiting value for each fuel type is the smaller of the flow-dependent and power-dependent MAPLHGR limits, MAPLHGRF and MAPLHGRp. The flow-dependent MAPLHGR limit, MAPLHGRF, is the product of the MAPLHGR flow factor, MAPFACF, shown in Figure 3.1-2 and the MAPLHGR for rated power and flow conditions, given in Tables 3.1-1 and 3.1-2 for GE14 and GNF2, respectively. The power-dependent MAPLHGR limit, MAPLHGRP, is the product of the MAPLHGR power factor, MAPFACP in Figure 3.1-3 and the MAPLHGR limit for rated power and flow conditions, given in Tables 3.1-1 and 3.1-2.

MAPLHGR for rated power and flow conditions for the most limiting lattice in each fuel type (excluding natural uranium lattices) are presented in Figure 3.1-1.

MAPLHGR limits are based on ECCS-LOCA considerations. For each lattice type, the MAPLHGR values for rated power and flow conditions are listed in Tables 3.1-1 and 3.1-2, which are obtained from the Supplemental Reload Licensing Report (Ref. 5.15).

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 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.

Per the GNF letter in Reference 5.22, the dashes on the MAPLHGR Tables in the SRLR on which Tables 3.1-1 and 3.1-2 are based, indicate that no specific calculation of MAPLHGR limit was done at that point. Additionally, the limit value -givenfor last exposure statepoint listed is applicable for higher exposures up to 63.5 GWD/ST (70 GWD/MT). This is consistent with LOCA analysis reports (References 5.3 and 5.21).

As in previous cycle, 3D monicore is designed to apply the MAPLHGR limits consistent with this explanation.

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. In addition, due to a restriction placed in GNF2 generic fuel licensing (Reference 5.23), the Peak Pellet exposure for GNF2 is limited to 45 GWD/MT.

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.

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 PBypa s, MCPRp is the product of the rated power and flow MCPR operating limit presented in Yable 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 '".

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 oft in Table 3.3-1 shall be equal to 1.0, unless it is calculated from the results of the surveillance testing of Technical Specification 4.3.C. TS 4.11.C defines t.

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%.

PILGRIM NUCLEAR POWER STATION PNPS CORE OPERATING LIMITS REPORT RTYPE: G4.02 3.4 Power/Flow Relationship Durinc Power Operation Reference Technical Specification: 3.11.D The Cycle 18 stability analysis credited the flow clamp feature of the FCTR cards from BOC to 2,000 MWD/ST to ensure the dominance of Core Wide Oscillations. APRM Flux scram and Rod Block curves including the flow clamp have been developed for Cycle 18. Additionally, the Cycle 18 ATWS analysis requires a change to the power/flow map from BOC to 5,000 MWD/ST to ensure that the ATWS peak pressure remains below the 1500 psig acceptance criteria. The curves may be changed consistent with the exposure ranges provided on Figures 3.4-1 through 3.4-5: however, curves that apply to earlier cycle exposure ranges are conservative for the remainder of the cycle and may remain in place if desired.

The power/flow relationship shall not exceed the limiting values shown on the Power/Flow Operating Maps in Figures 3.4-1 through 3.4-3 when in Two Loop Operation for the given exposure ranges. The power/flow relationship shall not exceed the limiting values shown on the Power/Flow Operating Maps in Figures 3.4-4 and 3.4-5 when in Single Loop Operation.

Cycle 18 operation is not fully analyzed for reduced feedwater temperature for issues other than thermal limits. This report contains only the thermal limit analysis results for reduced feed water temperature mode.

For the Cycle 18 Stability analysis, the exclusion and the buffer regions shown in Figures 3.4-1 through 3.4-5 are based on Stability Solution I-D (references 5.4, 5.12, 5.15 and 5.20)

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.
