3. General Information Power and flow dependent limits are listed for various power and flow levels. Linear interpolation is to be used to find intermediate values.

Rated core flow is 98 Mlb/hr. Operation up to 108% rated flow is licensed for this cycle. Licensed rated thermal power is 2957 MWth.

MCPR(P) and MCPR(F) values are independent of scram time.

LHGRFAC(P) and LHGRFAC(F) values are independent of scram speed.

For thermal limit monitoring above 100% rated power or 100% rated core flow, the 100% rated power and the 100% core flow values, respectively, can be used unless otherwise indicated in the applicable table.

The OPRM PBDA trip settings are based, in part, on the cycle specific OLMCPR and the power dependent MCPR limits. Any change to the OLMCPR values and/or the power dependent MCPR limits should be evaluated for potential impact on the OPRM PBDA trip settings.

For both Base and EOOS DLO/SLO conditions, for operation at Nominal FWT, the OLMCPR limit is applicable to a variation of +/- 10°F in feedwater temperature. For operation outside of Nominal FWT, a feedwater temperature reduction of up to 120°F is also supported for Base and EOOS DLO/SLO conditions for cycle operation through EOC.

4. Average Planar Linear Heat Generation Rate The MAPLHGR values for the most limiting lattice (excluding natural uranium) of each fuel type as a function of average planar exposure is given in Tables 4-1 and 4-2. During single loop operation, these limits are multiplied by the SLO multiplier listed in Table 4-3.

5. Operating Limit Minimum Critical Power Ratio 5.1. Manual Flow Control MCPR Limits The OLMCPR is determined for a given power and flow condition by evaluating the power-dependent MCPR and the flow-dependent MCPR and selecting the greater of the two.

5.1.1. Power - Dependent MCPR For operation at less than 38.5% core thermal power, the OLMCPR as a function of core thermal power is shown in Tables 5-7 and 5-8. For operation at greater than 38.5% core thermal power, the OLMCPR as a function of core thermal power is determined by multiplying the applicable rated condition OLMCPR limit shown in Tables 5-2 through 5-6 by the applicable MCPR multiplier K(P) given in Tables 5-7 and 5-8. For operation at exactly 38.5% core thermal power, the OLMCPR as a function of core thermal power is the higher of either of the two methods evaluated at 38.5% core thermal power.

5.1.2. Flow - Dependent MCPR Tables 5-9 and 5-10 give the MCPR(F) limit as a function of the flow based on the applicable plant condition. The MCPR(F) limit determined from these tables is the flow dependent OLMCPR.

5.2. Automatic Flow Control MCPR Limits Automatic flow control MCPR limits are not provided.

5.3. Scram Time TSSS, tSS, and NSS refer to scram speeds. TSSS is the Technical Specification Scram Speed, ISS is the Intermediate Scram Speed, and NSS is the Nominal Scram Speed.

The scram time values are shown in Table 5-1.

The NSS scram times are based on a conservative interpretation of scram time surveillance measurements. In the event that plant surveillance shows these scram insertion times to be exceeded, the MCPR limits are to default to the values which correspond to the ISS scram time. The ISS times have been chosen to provide an intermediate value between the NSS and the TSSS, but the interpolation between these values is not supported by Westinghouse methodology. In the event that the ISS times are exceeded, MCPR limits for the TSSS apply.

COLR Quad Cities 2 Cycle 19 Revision 2 Page 10 1 5.4. Recirculation Pump Motor Generator Settings Cycle 19 was analyzed with a maximum core flow runout of 110%; therefore the recirculation pump motor generator scoop tube mechanical and electrical stops must be set to maintain core flow less than 110% (107.8 Mlb/hr) for all runout events (Reference 16). This value is consistent with the analyses of Reference 3.

The limit applies to all Optima2 bundle designs.

The linear heat generation rate (LHGR) limit is the product of the exposure dependent LHGR limit from Tables 6-1 through 6-17 and the minimum of: the power dependent LHGR factor, LHGRFAC(P) or the flow dependent LHGR factor, LHGRFAC(F) where applicable. The LHGRFAC(P) is determined from Table 6-18, 6-19, or 6-20. The LHGRFAC(F) is determined from Table 6-21, 6-22, or 6-23.

7. Rod Block Monitor The rod block monitor upscale instrumentation setpoints are determined from the relationships shown below (Reference 8):

ROD BLOCK MONITOR UPSCALE TRIP FUNCTION ALLOWABLE VALUE Two Recirculation Loop Operation 0.65 Wd + 56.1%

Single Recirculation Operation Loop __

0.65 Wd + 51.4%

.65__W___+_5___4%

The setpoint may be lower/higher and will still comply with the rod withdrawal error (RWE) analysis because RWE is analyzed unblocked.

The allowable value is clamped with a maximum value not to exceed the allowable value for a recirculation loop drive flow (Wd) of 100%.

Wd - percent of recirculation loop drive flow required to produce a rated core flow of 98 Mlb/hr.

8. Stability Protection Setpoints The OPRM PBDA trip settings (Reference 3):

Corresponding Maximum PBDA Trip Amplitude Setpoint (Sp) Confirmation Count Setpoint (Np) 1.16 17 The PBDA is the only OPRM setting credited in the safety analysis as documented in the licensing basis for the OPRM system.

The OPRM PBDA trip settings are based, in part, on the cycle specific OLMCPR and the power dependent MCPR limits. Any change to the OLMCPR values and/or the power dependent MCPR limits should be evaluated for potential impact on the OPRM PBDA trip settings.

The OPRM PBDA trip settings are applicable when the OPRM system is declared operable, and the associated Technical Specifications are implemented.

For operation under all limit sets, a 120°F reduction in feedwater temperature throughout the cycle was analyzed and is subject to the restrictions in Reference 10 (Final Feedwater Temperature Reduction or Feedwater Heaters OOS).

2 Each EOOS option except TBPOOS requires the opening profile for the turbine bypass valves provided in Reference 15 to be met. These conditions also support I Turbine Bypass Valve OOS if the assumed opening profile (Reference 15) for the remaining 8 Turbine Bypass Valves is met. If the opening profile is not met with 8 or 9 operating Turbine Bypass Valves, or if more than one Turbine Bypass Valve is OOS, utilize the TBPOOS condition.

3 Coastdown operation is defined as any cycle exposure beyond the full power, all rods out condition with plant power slowly lowering to a lesser value while core flow is held constant. Coastdown analysis has been performed with bounding assumption of full power operation up to cycle exposure of 16,000 MWD/MTU.

4 If the Base Case limit set (DLO only) is being used and the PLU is taken OOS for a surveillance and the surveillance is done at 2:80% rated reactor power, an administrative limit of 0.98 on MFLPD and 0.91 on MFLCPR for scram time greater than ISS but less than or equal to TSSS, or 0.89 on MFLCPR for scram time greater than NSS but less than or equal to ISS, or 0.89 on MFLCPR for scram time less than or equal to NSS limit can be used instead of the PLUOOS (DLO) thermal limit set. If the Base Case limit set (DLO only) is being used and the PLU is taken OOS for a surveillance and the surveillance is done at >95% rated reactor power, an administrative limit of 0.99 on MFLPD and 0.93 on MFLCPR for scram time greater than ISS but less than or equal to TSSS, or 0.91 on MFLCPR for scram time greater than NSS but less than or equal to ISS, or 0.92 on MFLCPR for scram time less than or equal to NSS limit can be used instead of the PLUOOS (DLO) thermal limit set. The MAPRAT limit is not impacted by PLUOOS and thus continue to monitor to 1.00 in this condition.

5 Operation up to 108% rated core flow is licensed for this cycle.

6 For operation with a pressure regulator out-of-service (PROOS), the TCV Slow Closure limits should be applied. For operation with a PROOS and TCV slow closure, the TCV slow closure limits are applicable.

For operation with a PROOS and PLUOOS, the PLUOOS limits are applicable. (Reference 3) 7 A single MSIV may be taken OOS (shut) under all OOS Options, so long as core thermal power is maintained <75% of 2957 MWth (Reference 3).

8 The cycle specific stability analysis may impose restrictions on the Power-to-Flow map and/or restrict the applicable temperature for feedwater temperature reduction. See Reference 3.

For Base DLO and Base SLO cases, as well as all EOOS conditions, operation for both nominal and up to 120'F reduction in Feedwater temperature are supported. For both Base DLO/SLO and EOOS conditions, for operation at nominal feedwater temperature, the OLMCPR limit is applicable to a variation of +1- 1OF in feedwater temperature, and a steam dome pressure band of +/- 15 psi is applicable.

'0 For operation with a Turbine Stop Valve out-of-service (TSV OOS), the TCV Stuck Closed limits should be applied (Reference 3). TSV OOS and TCV Stuck Closed is not an analyzed out-of-service combination.
