2. General Information Licensed rated thermal power is 2957 MWth. Rated core flow is 98 MIb/hr. Operation up to 108% rated flow is licensed for this cycle. For allowed operating regions, see plant power/flow map.

The licensing analysis supports full power operation to EOFPL+25 EFPD (16962 MWd/MTU) and coastdown to a power level of 70%, given all burnup limits are satisfied. (Reference 3)

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

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

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

Only MCPR operating limits vary with scram speed. All other thermal limits are applicable with either NSS, ISS, or TSSS.

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.

4. Operating Limit Minimum Critical Power Ratio The OLMCPRs for Q2C22 were established to protect the SLMCPR during the anticipated operational occurrences.

4.1. 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.

4.1.1. Power - Dependent MCPR For operation at less than 38.5% of rated core thermal power, the OLMCPR as a function of core thermal power (MCPR(P)) is shown in Tables 4-5 and 4-6. For operation at greater than 38.5% of rated 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 4-2 through 4-4 by the applicable MCPR multiplier K(P) given in Tables 4-5 and 4-6. For operation at exactly 38.5% of rated core thermal power, the OLMCPR as a function of core thermal power is the maximum of either of the two aforementioned methods evaluated at 38.5% of rated core thermal power.

4.1.2. Flow - Dependent MCPR Table 4-7 gives the MCPR(F) limit as a function of the flow based on the applicable plant condition. The MCPR(F) limit determined from this table is the flow-dependent OLMCPR.

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

COLR Quad Cities 2 Rev. 9 4.3. Scram Time TSSS, ISS, and NSS refer to scram speeds. The scram time values associated with these speeds are shown in Table 4-1. The TSSS scram times shown in Table 4-1 are the same as those specified in the Technical Specifications (Reference 13). 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.

To utilize the MCPR limits for Nominal Scram Speed in Table 4-4, the average control rod insertion time at each control rod insertion fraction must be equal to or less than the NSS time shown on Table 4-1 below.

To utilize the MCPR limits for Intermediate Scram Speed in Table 4-3, the average control rod insertion time at each control rod insertion fraction must be equal to or less than the ISS time shown on Table 4-1 below.

To utilize the MCPR limits for Technical Specification Scram Speed in Table 4-2, the average control rod insertion time at each control rod insertion fraction must be equal to or less than the TSSS time shown on Table 4-1 below.

The average control rod insertion time is defined as the average control rod insertion time of all operable control rods based on the sum of the most recent scram time data divided by the number of operable drives. The time for inoperable drives (notch 00) can be conservatively included for calculation of core average scram speed. (Reference 3)

Table 4-1 Scram Times (References 3, 13, and 15)

Control Rod Insertion Fraction (%) TSSS (seconds) ISS (seconds) NSS (seconds) 5 0.48 0.360 0.324 20 0.89 0.720 0.694 50 1.98 1.580 1.510 90 3.44 2.800 2.670 4.4. Recirculation Pump ASD Settings Cycle 22 was analyzed with a maximum core flow runout of 110%; therefore the recirculation pump ASD must be set to maintain core flow less than 110% (107.8 Mlb/hr) for all runout events (Reference 4).

5. Linear Heat Generation Rate The TMOL at rated conditions for the Optima2 fuel is established in terms of the maximum LHGR as a function of rod nodal exposure. The limits in Tables 5-1 through 5-4 apply to fresh SVEA-96 Optima2 bundle designs for Cycle 22 (fuel bundle types UH22, U122, and UJ22). While the Table 5-4 limits apply to bundle designs for Cycles 20 and 21 (fuel bundle types UC20, UD20, UE21, UF21, and UG21) as well as any natural blanket segment in the core (Lattice types 91 and 98).

The limits changed for the Cycle 22 fresh fuel due to the increase in Uranium enrichment in the Gadolinia rods, which meant that it was no longer guaranteed that all Gadolinia rods would stay below the TMOL. Therefore, LHGR limits for Cycle 22 are defined by lattice type in order for a conservative limit to be applied independent of the Gadolinia content. The natural Uranium lattices (Lattice types 91 and 98) are still monitored with the original U02 limits since they are not enriched and do not contain Gadolinium. (Reference 3)

The LHGR limit is the product of the exposure dependent LHGR limit from Table 5-1 through Table 5-4 and the minimum of: the power-dependent LHGR multiplier, LHGRFAC(P), or the flow-dependent LHGR multiplier, LHGRFAC(F), as applicable. The LHGRFAC(P) is determined from Table 5-5. The LHGRFAC(F) is determined from Table 5-6, and is applicable for DLO and SLO and for all Base Case and EOOS conditions.

6. Control Rod Block Setpoints The rod block monitor upscale instrumentation setpoints are determined from the relationships shown in Table 6-1:

Operation 0.65_Wd_+_56.1%

Single Recirculation Loop 0.65 Wd + 51.4%

Operation The setpoint may be lower/higher and will still comply with the RWE analysis because RWE is analyzed unblocked (Reference 4).

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.

7. Stability Protection Setpoints The OPRM PBDA trip settings are given in Table 7-1.

Table 7-1 OPRM PBDA Trip Settings (Reference 3)

PBDA Trip Amplitude Setpoint (Sp) Corresponding Maximum Confirmation Count Setpoint (Np) 1.14 16 The PBDA is the only OPRM setting credited in the safety analysis as documented in the licensing basis for the OPRM system (Methodology reference 10).

The OPRM PBDA trip settings are based, in part, on the cycle specific OLMCPR and the power/flow-dependent MCPR limits. Any change to the OLMCPR values and/or the power/flow-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.

• Also applicable to one TSV stuck closed or one TCV and TSV stuck closed in the same line (Reference 3).

• • EOOS condition TCV Stuck Closed has identical thermal limits as the Base Case. Therefore, this condition will use the Base Case thermal limit set.

Common Notes - Applicable to Base Case and all EOOS Combinations for DLO/SLO:

1. All modes are allowed for operation at MELLLA, ICF (up to 108% rated core flow), full power operation to End of Full Power Life + 25 Effective Full Power Days (16962 MWd/MTU), and a coastdown period to 70% of rated thermal power, subject to the power restrictions in Tables 8-2 and 8-3 (Reference 3). Each OOS Option may be combined with up to 2 TIP machines OOS (16 TIP channel traces and 2 common channel traces not obtained), provided the requirements for utilizing SUBTIP methodology are met as clarified in Reference 14, and up to 50% of the LPRMs OOS with an LPRM calibration frequency of 2500 EFPH (2000 EFPH + 25%)

(Reference 16).

2. Nominal FWT results are valid for application within a +10°F/-30°F temperature band around the nominal FWT and operating steam dome pressure region bounded by the maximum value of 1020 psia and the minimum pressure curve in Reference 4. (Reference 3)

Page 60 of 63

COLR Quad Cities 2 Rev. 9

3. For operation outside of Nominal FWT, FWTR results are valid for the minimum FWT curve and support a feedwater temperature reduction of up to 120°F for Base and all EOOS DLO/SLO conditions for cycle operation through EOC subject to the restriction in Reference 12 for feedwater temperature reductions of greater than 100°F. The restriction is to maintain less than 100% rod line with a feedwater temperature reduction of greater than 100°F. This includes, but is not limited to, FWHOOS and final FWTR. For a feedwater temperature reduction of between 30°F and 120 0 F, the FWTR limits should be applied.

4. All analyses support the fastest TBV (assumed to be #1) 0OS, with the remaining 8 TBVs 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 TBV COS (or partially closed TBVs equivalent to one closed TBV), if the assumed opening profile for the remaining TBVs is met. If the opening profile is NOT met, or if the TBV system cannot pass an equivalent of 29.6%

of vessel rated steam flow, utilize the TBVOOS condition. (Reference 3)

5. For all cases analyzed including TBVOOS, equivalent of 2 of the first 3.4 TBVs must be capable of opening via the pressure control system while TBVs #5-9 are allowed to be 0OS. For all cases except TBVOOS, the equivalent of 8 of 9 TBVs (as stated in Note 4 above) are required to trip open on TCV fast closure or on TSV closure. The TBVOOS condition assumes that all of the TBVs do not trip open on TCV fast closure or on TSV closure. (Reference 3)

6. A single Main Steam Isolation Valve (MSIV) may be taken 0OS (shut) under any of the specified 0OS options as long as core thermal power is maintained < 75% of 2957 MWt. (Reference 3)

Table 8-2 Core Thermal Power Restriction for COS Conditions (Reference 3)

EOOS Condition Core Thermal Power (% of Rated Power)

Base, PLUOOS, TCV Slow Closure < 100 One TCV Stuck Closed * < 75% **

• Also applicable to one TSV stuck closed or one TCV and TSV stuck closed in the same line (Reference 3).

• • Based on a nominal capacity of 3.7% of rated steam flow for each turbine bypass valve. The maximum power level assumed for operation with 3 TCVs and one TBVOOS is 75% of rated power with 2 TBVs available to limit system pressurization. Operation above 75% of rated core thermal power is analyzed and allowed, but requires raising the MCFL setpoint and/or increasing TBV availability to increase the available total reactor vessel steam flow capability as described in Reference 3.
