a. Normal Feedwater Heating or Low Thermal Reactor Power:

TFW > TFw(rated)-500F OR P < 30%,

WhereTrw = rated equivalent Feedwater Temperature in OF; P= Core Power, % of rated.

When the mode switch is in the RUN position, the average power range monitor (APRM) flux scram trip setting (S r), in percent of rated thermal power, as a function of aligned drive flow shall be as given by Figure 2.1-1. Ss is clamped at 120% of rated core thermal power.

Formulae used to develop Figure 2.1-1 are listed in Table 2.1-1.

The aligned drive flow to the input drive flow relationship is as follows:

WD = WDl 00 (AD40) - Wn4O (AD1 00) + AWD*WD1 AWD - AD1 00 + AD40 Where:

Operation with -one recirculation loop out of service is restricted by License Condition 3.E.

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. The 50 OF Feedwater Temperature reduction limit only applied to the APRM FCTR Card Settings, based on the validity range of Stability Analysis.

Drive flow alignment will be done within 7 days of reaching equilibrium xenon at 100 % Core Thermal Power after a Refueling Outage.

b.

Reduced Feedwater Heating:

TFw < TFw(rated) - 501F AND P > 30%,

Cycle 15 operation is not fully analyzed for reduced feedwater temperature. Core stability has been analyzed for feedwater temperature reduction. Use of this analysis requires implementation of the appropriate settings on the Flow Control Trip Reference (FCTR) cards, changes to thermal limits and Power to Flow map.

PILGRIM NUCLEAR POWER STATION PNPS CORE OPERATING LIMITS REPORT RTYPE: G4.02 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 MAPLHGR The flow-dependent MAPLHGR limit, MAPLHGRF, is the product of the MRPLHGR flow factor, MAPFACF, shown in Figure 3.1-3 for both GE1 1 and GE14 fuels and the MAPLHGR for rated power and flow conditions, given in Tables 3.1-1 for GE1 1 fuel or Table 3.1-2 for GE14 fuel. The power-dependent MAPLHGR limit, MAPLHGRp, is the product of the MAPLHGR power factor, MAPFACp, (shown in Figure 3.1-4 for both GE1 1 and GE14 fuels) and the MAPLHGR limit for rated power and flow conditions, given in Tables 3.1-1 for GE1 1 fuel or Table 3.1-2 for GE14 fuel.

The MAPLHGR for rated power and flow conditions for each fuel type as a function of axial location and average planar exposure are based on the approved methodology referenced in Section 5.0 and programmed in the plant process computer. The MAPLHGR for rated power and flow conditions for the most limiting lattice in each fuel type (excluding natural uranium lattices) are presented in Figures 3.1-1 and 3.1-2. The MAPLHGR limits for off-rated conditions are based on the approved methodology in reference 5.3.

'MAPLHGR limits are based on ECCS-LOCA considerations. The new GNF SER issued by the NRC (Reference 5.18) documents the basis for the elimination of an Upperbound PCT limit. Cycle 15 MAPLHGR limits are based on use of this SER. Peak LHGR and peak MAPLHGR were both reduced in order to obtain a margin to the Licensing basis PCT limit of 2200 "F. Lattice and exposure dependent MAPLHGR limits were to control the peak LHGR and MAPLHGR within a node. For each lattice type, the MAPLHGR values for rated power and flow conditions are listed in Tables 3.1-1 for GE1 1 fuel which are obtained from the Supplemental Reload Licensing Report (Ref. 5.14). MAPLHGR Values for GE14 fuel reported by the SRLR were found to be in error as reported by GE in 1 OCFR50.46 notification 2004-01 (reference 5.22).

Therefore, the MAPLHGR values in the SRLR (Ref. 5.14) are superceded by Reference 5.21, which reported corrected MAPLHGR limit values. The corrected values calculated using SAFER/GESTR and were design verified by GE.

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. Pbypass is currently set at 32.5% power.

Reference Technical Specification: 3.1 1.B During reactor power operation, the LHGR of any rod in any fuel assembly at any axial location shall not exceed the rated power and rated core flow limits represented by Figures 3.2-1 and 3.2-2, with the detailed values presented in Reference 5.16. 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 LHGR. The flow-dependent LHGR limit, LHGRF, is the product of the LHGR flow factor, LH8 RFACF, shown in Figure 3.2-3 and the LHGR for rated power and flow conditions in Reference 5.16. The power-dependent LHGR limit, LHGRp, is the product of the LHGR power factor, LHGRFACp, shown in Figure 3.2-4 and the LHGR for rated power and flow conditions in Reference 5.16.

The LHGR limits for each fuel type as a function of axial location, rod power and exposure are based on the approved methodology referenced in Section 5.0 and programmed in the plant process computer. LHGR limits are based on thermal-mechanical design limits in reference 5.1. LHGR Curves in Figures 3.2-1 and 3.2-2 are representative curves for U02 fuel rods and Gd containing rods in GE1l1 and GE14 fuel bundles. Gd containing fuel rods have different LHGR limits that are also exposure dependent. Reference 5.16 documents the detailed proprietary curves and values. Limits specified in Reference 5.16 are programmed into the 3D Monicore Process Computer.

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 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 core thermal powers less than or equal to PB pa s, the power-dependent MCPR operating limit, MCPRp, is provided in Figure 3.3-2 for nolymal Feedwater Temperature. Above P Bvnas, MCPRp is the product of the rated power and flow MCPR operating limit presented in iae 3.3-1, and the Kp factor presented in Figure 3.3-2, when Turbine Bypass is in service and Feedwater Temperature is normal. Figure 3.3-2 indicates MCPRp up to 45% power, which is the maximum analyzed value for Pbypass. The rated power and flow MCPR operating limits presented in Tables 3.3-1 are functions of T for both GE11 and GE14 fuels. In arriving at the MCPRp for off-rated power conditions, Kp from Figure 3.3-2 is multiplied by the rated OLMCPR from Table 3.3-1 for the appropriate fuel type, GE1 1 or GE14, when power is above Pbypass. For power level less than Pbypass, the MCPRp is independent of the fuel type and can be directly read from Figure 3.3-2.

The value of T 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, as follows:

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 power/flow relationship shall not exceed the limiting values shown on the Power/Flow Operating Map in Figure 3.4-1. The Power/Flow Map, Figure 3.4-1 is applicable to operation with Normal feedwater heating. Cycle 15 operation is not fully analyzed for reduced feedwater temperature.

Intentional operation within the Restricted Region is prohibited. The Restricted Region boundary as a function of aligned drive flow is as given in Figure 2.2 -1.

Note: The boundary of the Restricted Region is established by analysis in terms of thermal power and core flow as shown in Figure 3.4 - 1. The Restricted Region boundary is defined by the locus of APRM Rod Block setpoints as a function of the reactor recirculation flow as shown by Figure 2.2-1.
