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 +1 0°F/-30°F in feedwater temperature. For operation outside of Nominal FWT, a feedwater temperature reduction of up to 120°F is supported for Base and EOOS DLO/SLO conditions for cycle operation through EOC subject to the restriction in Reference 10 for feedwater temperature reductions of greater than 100 OF. The restriction is to maintain less than 100% rod line. This includes, but is not limited to, FWHOOS and final FWTR.

For a feedwater temperature reduction of between 30°F and 120'F, the FWTR limits should be applied.

4. Average Planar Linear Heat Generation Rate The MAPLHGR values for the most limiting lattice (excluding natural uranium) of the GE14 bundle types as a function of average planar exposure is given in Table 4-1. During single loop operation, these limits are multiplied by the SLO multiplier listed in Table 4-16.

For Optima2 fuel, lattice-specific MAPLHGR values for DLO and SLO are provided in Tables 4-2 through 4-15.

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 5-5 and 5-6. 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 5-4 by the applicable MCPR multiplier K(P) given in Tables 5-5 and 5-6. 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 Table 5-7 gives 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.

COLR Quad Cities 2 Cycle 20 Revision 0 Page 18 5.3. Scram Time TSSS, ISS, 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 TSSS scram times shown in Table 5-1 are the same as those specified in the Technical Specifications (Reference 11).

Reference 3 indicates that the TSSS control rod insertion times that were actually used in the transient analysis are conservative with respect to the scram times specified in the Technical Specifications.

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 that 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.

Recirculation Pump Motor Generator Settings Cycle 20 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 14). This value is consistent with the analyses of Reference 3.

6. Linear Heat Generation Rate The maximum LHGR shall not exceed the zero exposure limit of 13.4 kW/ft for the following fuel bundles (Reference 9):

GE14-Pl ODNAB418-16GZ-1 OT-145-T6-2646 GE1 4-P1 ODNAB389-18GZ-1 OOT-1 45-T6-2650 The thermal mechanical operating limit at rated conditions for the Optima2 fuel is established in terms of the maximum LHGR given in Table 6-7 as a function of rod nodal exposure. 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 6-7 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 6-8, 6-9, or 6-10. The LHGRFAC(F) is determined from Table 6-11 or 6-12.

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 0.65 Wd + 56.1%

Operation I

Single Recirculation Loop 0.65 Wd + 51.4%

Operation I

W 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.

PBDA Trip Amplitude Setpoint (Sp)

Corresponding Maximum Confirmation Count Setpoint (Np) 1.14 16 The PBDA is the only OPRM setting credited in licensing basis for the OPRM system.

the safety analysis as documented in the 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.

2 All analyses support the fastest Turbine Bypass Valve (assumed to be #1) OOS, with the remaining 8 Turbine Bypass Valves meeting the assumed opening profile in Reference 15. The analyses also support Turbine Bypass flow of 29.6% of vessel rated steam flow, equivalent to one Turbine Bypass Valve OOS (or partially closed Turbine Bypass Valves equivalent to one closed Turbine Bypass Valve), if the assumed opening profile (Reference 15) for the remaining Turbine Bypass Valves is met. If the opening profile is NOT met, or if the Turbine Bypass Valve system cannot pass an equivalent of 29M6% of vessel rated steam flow, utilize the TBPOOS condition.

3 Coastdown 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 a cycle exposure of 15,877 MWD/MTU + 25 EFPD, or approximately 16,450 MWD/MTU.

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

5 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) 6 A single MSIV may be taken OOS (shut) under all OOS Options, as long as core thermal power is maintained < 75% of 2957 MWth (Reference 3).

7 For both Base and EOOS DLO/SLO conditions, for operation at nominal FWT, the OLMCPR limit is applicable to a variation of +10°F/-30°F in feedwater temperature, and an operating steam dome pressure region bounded by the maximum value of 1020 psia and the minimum pressure curve in Reference 16. For operation outside of nominal FWT, FW/TR of up to 120°F is also supported for cycle operation through EOC subject to the restriction in Reference 10 for feedwater temperature reductions of greater than 100 OF. The restriction is to maintain less than 100% rod line. This includes, but is not limited to FWHOOS and final FWTR. For a feedwater temperature reduction of between 30'F and 120'F, the FWTR limits should be applied.

8 For operation with one Turbine Stop Valve (TSV) Stuck Closed, the TCV Stuck Closed limits should be applied (Reference 3). One TSV Stuck Closed and one TCV Stuck Closed is not analyzed. For TSV Stuck Closed or TCV Stuck Closed, operation above 80% rated core thermal power is not analyzed.

9 For operation with a PROOS and TCV Stuck Closed, or for operation with a PLUOOS and Quad Cities Unit 2 Cycle 20

COLR Quad Cities 2 Cycle 20 Revision 0 Page 36 TCV Stuck Closed, operation is only allowed at or below 80% rated thermal power and the more restrictive of the flow-dependent limits (established by TCV Stuck Closed) and power-dependent limits (established by TCV Slow Closure and PLUOOS limits) apply. (Reference 3) 10 For the analyses to remain applicable, equivalent of 2 of the first 3.4 Turbine Bypass Valves must be capable of opening via the pressure control system while Turbine Bypass Valves #5-9 are allowed to be out of service. The TBPOOS condition assumes that all of the Turbine Bypass Valves do not trip open on Turbine Control Valve fast closure or on Turbine Stop Valve closure. For all cases except TBPOOS, the equivalent of 8 of 9 Turbine Bypass Valves (as stated in Note 2 above) are required to trip open on Turbine Control Valve fast closure or on Turbine Stop Valve closure.
