1.0 INTRODUCTION

AND SUAMIARY This report provides the cycle specific plant operating limits, which are listed below, for Fermi 2, Cycle 11, as required by Technical Specification 5.6.5. The analytical methods used to determine these core operating limits are those previously reviewed and approved by the Nuclear Regulatory Commission in GESTAR II.

The cycle specific limits contained within this report are valid for the full range of the licensed operating domain.

OPERATING LIMIT TECHNICAL SPECIFICATION APLHGR 3.2.1 MCPR 3.2.2 LHGR 3.2.3 RBM 3.3.2.1 BSP REGIONS 3.3.1.1 APLHGR = AVERAGE PLANAR LINEAR HEAT GENERATION RATE MCPR = MINIMUM CRITICAL POWER RATIO LHGR = LINEAR HEAT GENERATION RATE RBM - = ROD BLOCK MONITOR SETPOINTS BSP = BACKUP STABILITY PROTECTION

COLR - 11 Revision 0 COLR - I I Revision 0 Page 5 of 22 2.0 AVERAGE PLANAR LINEAR HEAT GENERATION RATE TECH SPEC IDENT OPERATING LIMIT 3.2.1 APLHGR 2.1 Definition The AVERAGE PLANAR LINEAR HEAT GENERATION RATE (APLHGR) shall be applicable to a specific planar height and is equal to the sum of the LINEAR HEAT GENERATION RATEs (LHGRs) for all the fuel rods in the specified bundle at the specified height divided by the number of fuel rods in the fuel bundle at the height.

2.2 Determination of MAPLHGR Limit The maximum APLHGR (MAPLHGR) limit is a function of reactor power, core flow, fuel type, and average planar exposure. The limit is developed, using NRC approved methodology described in References 1 and 2, to ensure gross cladding failure will not occur following a loss of coolant accident (LOCA). The MAPLHGR limit ensures that the peak clad temperature during a LOCA will not exceed the limits as specified in 10CFR50.46(b)(1) and that the fuel design analysis criteria defined in References 1 and 2 will be met.

The MAPLHGR limit during dual loop operation is calculated by the following equation:

MAPLHGRm,, = MIN (MAPLHGR (P), MAPLHGR (F))

where:

MAPLHGR (P) = MAPFAC (P) x MAPLHGRSD MAPLHGR (F) = MAPFAC (F) x MAPLHGRS.h Within four hours after entering single loop operation, the MAPLHGR limit is calculated by the following equation:

MAPLHGR,,., = MIN (MAPLHGR (P), MAPLHGR (F), MAPLHGR (SLO))

where:

MAPLHGR (SLO)= 1.0 x MAPLHGR, The Single Loop multiplier is 1.0 since the offrated ARTS limits bound the single loop MAPLHGR limit.

COLR - 11 Revision 0 Page 6 of 22 MAPLHGRsTD, the standard MAPLHGR limit, is defined at a power of 3430 MWt and flow of 105 Mlbs/hr for each fuel type as a function of average planar exposure and is presented in Table

1. When hand calculations are required, MAPLHGRsTD shall be determined by interpolation from Table 1. MAPFAC(P), the core power-dependent MAPLHGR limit adjustment factor, shall be calculated by using Sec'tion 2.2.1. MAPFAC(F), the core flow-dependent MAPLHGR limit adjustment factor, shall be calculated by using Section 2.2.2.

COLR - 11 Revision 0 Page 7 of 22 2.2.1 Calculation of AMAPFAC(P)

The core power-dependent MAPLHGR limit adjustment factor, MAPFAC(P), shall be calculated by one of the following equations:

For 0 <P <25:

No thermal limits monitoring is required.

For 25< P < 30:

With turbine bypass OPERABLE, For core flow < 50 Mlbs/hr, MAPFAC (P) = 0.606 + 0.0038 (P - 30)

For core flow > 50 Mlbs/hr, MAPFAC (P) = 0.586 + 0.0038 (P - 30)

With turbine bypass INOPERABLE, For core flow < 50 Mlbs/hr, MAPFAC(P)=0.490+ 0.0050(P-30)

For core flow > 50 Mlbs/hr, MAPFAC(P) = 0.438 + 0.0050(P -30)

For 30 <P< 100:

MAPFAC(P) = 1.0+0.005224(P-100) where: P = Core power (fraction of rated power times 100).

COLR - II Revision 0 Page 8 of 22 2.2.2 Calculation of MAPFAC(F)

The core flow-dependent MAPLHGR limit adjustment factor, MAPFAC(F), shall be calculated by the following equation:

MAPFAC(F) = MIN(1.0, AFX 100 + BF) where:

WT = Core flow (Mlbsfhr).

AF = Given in Table 2.

BF = Given in Table 2.

TABLE 2 FLOW-DEPENDENT MAPLHGR LIMIT COEFFICIENTS

COLR - 11 Revision 0 Page 9 of 22 3.0 MINIMUM CRITICAL POWER RATIO TECH SPEC IDENT OPERATING LIMIT 3.2.2 MCPR 3.1 Definition The MINIMUM CRITICAL POWER RATIO (MCPR) shall be the smallest Critical Power Ratio (CPR) that exists in the core for each type of fuel. The CPR is that power in the assembly that is calculated by application of the appropriate correlation(s) to cause some point in the assembly to experience boiling transition, divided by the actual assembly operating power.

3.2 Determination of Operating Limit MCPR The required Operating Limit MCPR (OLMCPR) at steady-state rated power and flow operating conditions is derived from the established fuel cladding integrity Safety Limit MCPR and an analysis of abnormal operational transients. To ensure that the Safety Limit MCPR is not exceeded during any anticipated abnormal operational transient, the most limiting transients have been analyzed to determine which event will cause the largest reduction in CPR. Three different core average exposure conditions are evaluated. The result is an Operating Limit MCPR which is a function of exposure and T. t is a measure of scram speed, and is defined in Section 3.3.2.

The OLMCPR shall be calculated by the following equation:

OLMCPR = MAX(MCPR(P), MCPR(F))

MCPR(P), the core power-dependent MCPR operating limit, shall be calculated using Section 3.3.

MCPR(F), the core flow-dependent MCPR operating limit, shall be calculated using Section 3.4.

In case of Single Loop Operation, the Safety Limit MCPR is increased to account for increased uncertainties in core flow measurement and TIP measurement, but OLMCPR does not change.

This is due to the fact that sufficient conservatism exists in the power-dependent MCPR operating limits to allow for the increase in the SLMCPR without requiring a corresponding increase in OLMCPR.

COLR - 11 Revision 0 Page 10 of 22 3.3 Calculation of MCPR(P)

MCPR(P), the core power-dependent MCPR operating limit, shall be calculated by the following equation:

MCPR(P) = Kp X OLMCPRoo1,o5 Kp, the core power-dependent MCPR Operating Limit adjustment factor, shall be calculated by using Section 3.3.1.

OLMCPR 1 0oC105 shall be determined by interpolation from Table 3, and X shall be calculated by using Section 3.3.2.

OLMCPRioalos where: KBYP = 2.61 for core flow < 50 Mlbs/hr

Kp = 1.28 + (0.0134 x (45- P))

For 45<P<60:

Kp = 1.15 + (0.00867 x (60-P))

For 60<P<100:.

Kp = 1.0 + (0.00375 x (100 - P))

where: P = Core power (fraction of rated power times 100).

COLR - 11 Revision 0 Page 12 of 22 3.3.2 Calculation of T The value of t, which is a measure of the conformance of the actual control rod scram times to the assumed average control rod scram time in the reload licensing analysis, shall be calculated by using the following equation:

1 B TrA - TB where: TA = 1.096 seconds mB = 0.830 + 0.019 x 1.65 seconds Ni=

rave-ENi n = number of surveillance tests performed to date in cycle, Ni = number of active coritrol rods measured in the ih surveillance test,

The value of T shall be calculated and used to determine the applicable OLMCPR 10 o1 105 value from Table 3 within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> of the conclusion of each control rod scram time surveillance test required by Technical Specification Surveillance Requirements 3.1.4.1, 3.1.4.2, and 3.1.4.4.

Prior to performance of the initial scram time measurements for the cycle, a r value of 1.0 shall be used to determine the applicable OLMCPR1 OO/ 105 value from Table 3.

COLR - 11 Revision 0 Page 14 of 22 4.0 LINEAR HEAT GENERATION RATE TECH SPEC IDENT OPERATING LIMIT 3.2.3 LHGR 4.1 Definition The LINEAR HEAT GENERATION RATE (LHGR) shall be the heat generation rate per unit length of fuel rod. It is the integral of the heat flux over the heat transfer area associated with the unit length. By maintaining the operating LHGR below the applicable LHGR limit, it is assured that all thermal-mechanical design bases and licensing limits for the fuel will be satisfied.

4.2 Determination of LHGR Limit The maximum LHGR limit is a function of reactor power, core flow, fuel and rod type, and fuel rod nodal exposure. The limit is developed, using NRC approved methodology described in References 1 and 2, to ensure the cladding will not exceed its yield stress and that fuel thermal-mechanical design criteria will not be violated during any postulated transient events. The LHGR limit ensures the fuel mechanical design requirements as defined in References 1 and 2 will be met.

The LHGR limit during dual loop operation is calculated by the following equation:

LHGR,,, = MN (LHGR (P), LHGR (F))

where:

LHGR (P) = LHGRFAC (P) x LHGR,,,

LHGR (F) = LHGRFAC (F) x LHGR,,,

LHGRSTD, the standard LHGR limit, is defined at a power of 3430 MWt and flow of 105 Mlbs/hr for each fuel and rod type as a function of fuel rod nodal exposure and is presented in Table 5.

Table 5 contains only the most limiting Gadolinia LHGR limit for the maximum allowed Gadolinia concentration of the applicable fuel product line. When hand calculations are required, LHGRSTD shall be determined by interpolation from Table 5. LHGRFAC(P), the core power-dependent LHGR limit adjustment factor, shall be calculated by using Section 4.2. 1.

LHGRFAC(F), the core flow-dependent LHGR limit adjustment factor, shall be calculated by using Section 4.2.2.

Regions are identified (refer to Table 8 and Figure 1) that are either excluded from planned entry (Scram Region), or where specific actions are required to be taken to immediately leave the region (Exit Region). A region is also identified where operation is allowed provided that additional monitoring is performed to verify that the reactor core is not exhibiting signs of core thermal hydraulic instability (Stability Awareness Region).

The boundaries of these regions are established on a cycle specific basis based upon core decay ratio calculations performed using NRC approved methodology.

These regions are only applicable when the Upscale Trip function of the Oscillation Power Range Monitoring System (OPRM) is inoperable. It must be noted that the Cycle 11 region boundaries defined in Table 8 and illustrated in Figure 1 are not applicable to operation with Feedwater Heaters Out-Of-Service (FWHOOS) or with Final Feedwater Temperature Reduction (FFWTR).
