2. General Information This report is prepared in accordance with Technical Specification 5.6.5. The Q2C26 reload is licensed by Framatome. However, some legacy analyses by Westinghouse are still applicable for OPTIMA2 fuel as described in Reference 2.

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

The licensing analysis supports full power operation to EOCLB (38,401 MWd/MTU CAVEX). Note that this value includes coastdown, where full power operation is not expected. The transient analysis limits are provided for operation up to specific CAVEX exposures as defined in Section 4.3.

Coastdown is defined as operation beyond EOFPL (37,679 MWd/MTU CAVEX) with the plant power gradually reducing as available core reactivity diminishes. The Q2C26 reload analyses do not credit this reduced power during coastdown and the EOCLB limits remain valid for operation up to rated power.

Power and flow dependent limits are listed for various power and flow levels. Linear interpolation on power and flow (as applicable) is to be used to find intermediate values. Linear interpolation is also to be used for table items intentionally left blank, as indicated by boxes which are grayed out.

MCPRp for both fuel types varies with scram speed. All other thermal limits are analyzed to remain valid with NSS, ISS, and TSSS.

LHGRFACt is independent of feedwater temperature and EOOS conditions.

For thermal limit monitoring above 100% rated power or 108% rated core flow, the 100% rated power or the 108% core flow thermal limit values, respectively, shall be used. Steady state operation is not allowed in this region. Limits are provided for transient conditions only.

3. Average Planar Linear Heat Generation Rate Technical Specifications Sections 3.2.1 and 3.4.1 Table 3-1 provides the MAPLHGR SLO multipliers for ATRIUM 10XM and OPTIMA2 fuel. For OPTIMA2 natural uranium lattices, TLO and SLO MAPLHGR values are provided in Table 3-2. For all other OPTIMA2 lattices, lattice-specific MAPLHGR values for TLO are provided in Tables 3-3 through 3-22.

For ATRIUM 1OXM fuel, the lattice-specific MAPLHGR values for TLO can be found in Tables 3-23 through 3-24.

During SLO, the limits in Tables 3-3 through 3-24 are multiplied by the fuel-specific SLO multiplier listed in Table 3-1. The ATRIUM 10XM multiplier may be applied to OPTIMA2 for SLO conditions, as the ATRIUM 10XM multiplier is more limiting.

4. Operating Limit Minimum Critical Power Ratio Technical Specification Sections 3.2.2, 3.4.1, and 3.7.7 The OLMCPRs for Q2C26 were established so that less than 0.1 % of the fuel rods in the core are expected to experience boiling transition during an AOO initiated from rated or off-rated conditions and are based on the Technical Specifications SLMCPR values (Reference 2).

Tables 4-3 through 4-21 include MCPR limits for various specified EOOS conditions. The EOOS conditions separated by "/" in these tables represent single EOOS conditions and not any combination of conditions.

Refer to Section 8 for a detailed explanation of allowable combined EOOS conditions.

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 The OLMCPR as a function of core thermal power (MCPRp) is shown in Tables 4-3 through 4-20. MCPRp limits are dependent on scram times as described in Section 4.2, exposure as described in Section 4.3, fuel type, FWT, and whether the plant is in TLO or SLO. TLO limits for ATRIUM 10XM fuel are given in Tables 4-3 through 4-8 and SLO limits for ATRIUM 10XM are given in Tables 4-15 through 4-17. TLO limits for OPTIMA2 fuel are given in Tables 4-9 through 4-14 and SLO limits for OPTIMA2 fuel are given in Tables 4-18 through 4-20.

4.1.2. Flow-Dependent MCPR Table 4-21 gives the OLMCPR limit as a function of the flow (MCPRt) based on the applicable plant condition. These values are applicable to both ATRIUM 10XM and OPTIMA2 fuel.

Page 30 of65

COLR Quad Cities 2 Revision 13 4.2. Scram Time TSSS, ISS, and NSS refer to scram speeds. The scram time values associated with these speeds are shown in Table4-1. The TSSS scram times shown in Table 4-1 are the same as those specified in the Technical Specifications (Reference 4).

To utilize the OLMCPR limits for NSS in Tables 4-3, 4-6, 4-9, 4-12, 4-15, and 4-18, the average control rod insertion time at each control rod insertion fraction must be equal to or less than the NSS time shown in Table 4-1 below.

To utilize the OLMCPR limits for ISS in Tables 4-4, 4-7, 4-10, 4-13, 4-16, and 4-19, the average control rod insertion time at each control rod insertion fraction must be equal to or less than the ISS time shown in Table 4-1 below.

The "Average Control Rod Insertion Time" is defined as the sum of the control rod insertion times of all operable control rods divided by the number of operable control rods. Conservative adjustments to the NSS and ISS scram speeds were made to the analysis inputs to appropriately account for the effects of 1 stuck control rod and one additional control rod that is assumed to fail to scram (Reference 2).

To utilize the OLMCPR limits for TSSS in Tables 4-5, 4-8, 4-11, 4-14, 4-17, and 4-20, the control rod insertion time of each operable control rod at each control rod insertion fraction must be less than or equal to the TSSS time shown in Table 4-1 below. The Technical Specifications allow operation with up to 12 "slow" and 1 stuck control rod. One additional control rod is assumed to fail to scram for the system transient analyses performed to establish MCPRp limits (Reference 2).

Conservative adjustments to the TSSS scram speeds were made to the analysis inputs to appropriately account for the effects of the slow and stuck rods on scram reactivity (Reference 2).

For cases below 38.5% power (Pbypass), the results are relatively insensitive to scram speed, and only TSSS analyses were performed (Reference 2).

COLR Quad Cities 2 Revision 13 4.3. Exposure Dependent MCPR Limits Exposure-dependent MCPRp limits were established to support operation for the entire cycle duration. Note that the thermal limits are based on CAVEX. The CAVEX values at which point the MCPRp limits are required to be changed are shown in Table 4-2 below. The limits at a later exposure range can be used earlier in the cycle as they are the same or more conservative.

Although MCPRp values are the same for each CAVEX breakpoint, the values are split up based on CAVEX to maintain consistency with previous cycle's format.

Recirculation Pump ASD Settings Technical Requirement Manual 2.1.a.1 Quad Cities 2 Cycle 26 was analyzed with a slow flow excursion event assuming a failure of the recirculation flow control system such that the core flow increases slowly to the maximum flow physically permitted by the equipment, assumed to be 112% of rated core flow (Reference 2);

therefore, the recirculation pump ASD must be set to maintain core flow less than 112%

(109.76 Mlb/hr) for all runout events.

COLR Quad Cities 2 Revision 13

5. Linear Heat Generation Rate Technical Specification Sections 3.2.3, 3.4.1, and 3.7.7 The TMOL at rated conditions for the OPTIMA2 and ATRIUM 1OXM fuel is established in terms of the maximum LHGR as a function of peak pellet (rod nodal) exposure. The LHGR limits for OPTIMA2 fuel are presented in Tables 5-1 through 5-3. The limits in Table 5-1 apply to OPTIMA2 lattices that do not require Gadolinia set down penalties as well as any natural blanket segments in OPTIMA2 fuel (lattice types 91 and 98). The limits in Tables 5-2 and 5-3 apply to OPTIMA2 lattices that do require Gadolinia set down penalties. The LHGR limits for ATRIUM 10XM fuel are presented in Table 5-4.

The power- and flow-dependent LHGR multipliers (LHGRFACp and LHGRFAC1) are applied directly to the LHGR limits to protect against fuel melting and overstraining of the cladding during an AOO (Reference 2).

In all conditions, the margin to the LHGR limits is determined by applying the lowest multiplier from the applicable LHGRFACp and LHGRFAC1 multipliers for the power/flow statepoint of interest to the steady state LHGR limit (Reference 2).

LHGRFACp and LHGRFAC1 multipliers were established to support base case and all EOOS conditions for all Cycle 26 exposures and scram speeds. The LHGRFACp multipliers for ATRIUM 10XM and OPTIMA2 are presented in Table 5-5 and 5-6, respectively. The LHGRFAC1 multipliers for ATRIUM 10XM and OPTIMA2 are presented in Table 5-7 and Table 5-8; respectively. The LHGRFACp and LHGRFAC1 multipliers are applicable in both TLO and SLO.

The EOOS conditions separated by "/" in these tables represent single EOOS conditions and not any combination of conditions.

Corresponding Maximum PBDA Trip Amplitude Setpoint (Sp)

Confirmation Count Setpoint (Np) 1.13 15 The PBDA is the only OPRM setting credited in the safety analysis as documented in the licensing basis for the OPRM system (Methodology 2).

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.

COLR Quad Cities 2 Revision 13 Common Notes:

1. All modes are allowed for operation at MELLLA, ICF (up to 108% rated core flow), and coastdown subject to the power restrictions in Table 8-2 (Reference 2). The licensing analysis supports full power operation to EOCLB (38,401 MWd/MTU CAVEX). Note that this value includes coastdown, where full power operation is not expected. Each OOS Option may be combined with each of the following conditions (Reference 2):
a. Up to 40% of the TIP channels OOS
b. Up to 50% of the LPRMs OOS
c. An LPRM calibration frequency of up to 2500 EFPH
2. Nominal FWT results are valid for application within a +10°F/-30°F temperature band around the nominal FWT curve (Reference 2). For operation outside of nominal FWT, a FWT reduction of up to 120°F is supported for all FHOOS conditions listed in Table 8-1 for cycle operation through EOCLB (Reference 2). At lower power levels, the feedwater temperature reduction is less (Reference 2). Per Reference 9, there is a restriction which requires that for a FWT reduction greater than 100°F, operation needs to be restricted to less than the 100% rod line. For a feedwater temperature reduction of between 30°F and 120°F, the FHOOS limits should be applied.
3. The base case and EOOS limits and multipliers support operation with 8 of 9 turbine bypass valves operational (i.e., one bypass valve out of service) with the exception of the TBVOOS condition in which all bypass valves are inoperable (Reference 2). Use of the response curve in TRM Appendix H supports operation with any single TBV OOS. TRM Appendix H facilitates analysis with one valve OOS in that the capacity at 0.45 seconds from start of TSV closure is equivalent to the total capacity with eight out of the nine valves in service (Reference 7). The analyses also support Turbine Bypass flow of 29.6% of vessel rated steam flow (Reference 7), equivalent to one TBV OOS (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.
4. For the TBVOOS condition, analyses assume zero TBVs trip open and zero TBVs are available for pressure control during the slow portion of the transient analysis (Reference 7). Steam relief capacity is defined in Reference 7.
5. Failure of the main generator load reject trip relays to actuate (e.g., main generator load reject trip relays OOS) will render the turbine bypass valve system inoperable during load reject events (Reference 2). Operation with the main generator load reject trip relays out of service in TLO is supported by the TCV slow closure limits (Reference 2), meaning that, in accordance with Table 8-1, the PLUOOS/TCV SLOW C thermal limit set should be applied. This is applicable between 25% and 50% of rated thermal power.
6. Additional operating restrictions apply for both the MANFRV1 and MANFRV2 EOOS options as outlined in Section 1 of Reference 12. These operating restrictions apply when a Feedwater Regulating Valve is placed in manual for the conditions as described in the terms and definitions. Only one Feedwater Regulating Valve can be placed in manual. The additional EOOS conditions that are supported with MANFRV1 and MANFRV2 consist of 1 SRVOOS, 40% of TIP channels OOS and 50% of the LPRMs out-of-service. Other conditions associated with base case conditions, such as the feedwater temperature band, the pressure band, single and three-element level control, dome and turbine pressure control, and operation with 1 TBV OOS, are supported as discussed in Section 5.1 of Reference 2.
