2. 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. For allowed operating regions, see plant power/flow map.

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.

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

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

All thermal limits are analyzed to either NSS, ISS, or TSSS. Only MCPR limits vary with 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.

3. 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 3-1. During single, loop operation, these limits are multiplied by the SLO multiplier listed in Table 3-2.

For Optima2 fuel, lattice-specific MAPLHGR values for DLO and SLO are provided in Tables 3-3 through 3-20. Table 3-5 is based on the combination of limits from Reference 3 for Lattice 105, which is part of two types of Optima2 fuel bundles. For Optima2 fuel, the MAPLHGR for natural U lattices 101: Opt2-B0.71 and 108: Opt2-TO.71 must be set equal to the most restrictive MAPLHGR limits from among the enriched lattice types in the bundle (References 3 and 13).

4. Operating Limit Minimum Critical Power Ratio The Operating Limit Minimum Critical Power Ratios (OLMCPRs) for Q1C21 were established to protect the Safety Limit Minimum Critical Power Ratio (SLMCPR) for the anticipated operational occurrences. The SLMCPR values for DLO and SLO for Q1 C21 were determined to be 1.11 and 1.13 (Reference 23), respectively, which are unchanged from the NRC-approved values for the previous operating cycle (i.e., Q1C20). Likewise, the conservative OLMCPR adder applied to the GEl 4 fuel for Q1 C21 remains unchanged at the NRC-approved value of 0.934 (Reference 13).

In determining the SLMCPR values for Q1C21, Westinghouse applied the methodologies from CENPD-300-P-A, consistent with the manner specified in Limitations 1 through 6 and 8 of the NRC Safety Evaluation Report (SER) approving CENPD-300-P-A (References 15 and 23). The application of these methodologies was previously approved by the NRC for Q1 C20 in license amendment 237 to Renewed Facility Operating License DPR-29 (Reference 5).

Similarly, in both the determination and justification of the conservative adder applied to the GE14 fuel for Q1C21, Westinghouse complied with Limitation 7 of the SER approving CENPD-300-P-A (References 23 and 24). The NRC previously approved Westinghouse and Exelon compliance with Limitation 7 (i.e., for determination and justification of the conservative adder) in Reference 5.

In that the conservative adder for Q1 C21, and its justification, have not changed from previously-approved operating cycles, the NRC has already approved this determination and justification, as stated in Reference 25.

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 4-8 and 4-9. 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 Table 4-2 through 4-7 by the applicable MCPR multiplier K(P) given in Table 4-8 and 4-9. 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 Tables 4-10 through 4-13 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.

4.2. Automatic Flow Control MCPR Limits Automatic Flow Control MCPR Limits are not provided.

Quad Cities Unit 1 Cycle 21

COLR Quad Cities 1 Revision 0 Page 18 4.3. 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 4-1. Reference 13 indicates that TSSS control rod insertion time values used in the analysis are conservative in comparison to the values shown in Table 4-1.

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.

Recirculation Pump Motor Generator Settings Cycle 21 was analyzed with a maximum core flow runout of 110%; therefore the ASD must be set to maintain core flow less than 110% (107.8 Mlb/hr) for all runout events (Reference 26). This value is consistent with the analyses of Reference 13.

5. Linear Heat Generation Rate The maximum LHGR shall not exceed the zero exposure limit of 12.46 kW/ft for the following fuel bundles.

This limit is based on a 13.40 kW/ft peak LHGR from Reference 7 thermal mechanical limit reduced to 12.46 kW/ft based on References 27 and 28 which require a 7% reduction in peak LHGR. The maximum LHGR in Tables 5-1 and 5-2 is limited to 12.46 kW/ft, while the LHGR in Tables 5-3 and 5-4 was conservatively reduced by 7% for all burnup values.

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 5-1 through 5-5 and the minimum of: the power dependent LHGR Factor, LHGRFAC(P), the flow dependent LHGR Factor, LHGRFAC(F), or the single loop operation (SLO) multiplication factor where applicable. The LHGRFAC(P) is determined from Tables 5-6, 5-7, and 5-8. The LHGRFAC(F) is determined from Table 5-9 through 5-13.

6. Rod Block Monitor The Rod Block Monitor Upscale Instrumentation Setpoints are determined from the relationships shown below (Reference 6):

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

Operation Single Recirculation Loop 0.65 Wd + 51.4%

Operation 0.65_W__+_51.4%

The setpoint may be lower/higher and will still comply with the rod withdrawal error (RWE) analysis because RWE is analyzed unblocked. (Reference 26)

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 98.0 Mlb/hr.

7. Stability Protection Setpoints The OPRM PBDA Trip Settings (Reference 13):

PBDA Trip Amplitude Setpoint (Sp) Corresponding Maximum PD TConfirmation 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.

rated thermal power and

> The more restrictive of the flow-dependent limits (established by one TCV Stuck Closed) and power-dependent limits (established by TCV/TSV Stuck Closed, TCV.Slow Closure and PLUOOS limits) apply Common Notes - Applicable to all EOOS Combination

1. All modes are allowed for operation at MELLLA, ICF (up to 108%), full power operation to End of Full Power Life (EOFPL = 16556 MWd/MTU) + 25 Effective Full Power Days (EFPD) and a coastdown period to End of Cycle (EOC = 17211 MWd/MTU) (Reference 13), subject to the restrictions in Table 8-1). Each OOS Option may be combined with up to 18 TIP channels OOS provided the requirements (as clarified in Reference 16) for utilizing SUBTIP methodology are met and up to 50%

of the LPRMs OOS with an LPRM calibration frequency of 2500 EFPH (2000 EFPH +25%).

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 21. 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 21) 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 29.6% of vessel rated steam flow, utilize the TBVOOS condition.

Quad Cities Unit 1 Cycle 21

COLR Quad Cities 1 Revision 0 Page 39

3. For all cases, including TBVOOS, the equivalent of 2 of the first 3.4 Turbine Bypass Valves must be capable of responding to pressure increases under DEHC control. The TBVOOS 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 but does require that the equivalent of 2 of the first 3.4 Turbine Bypass Valves must be capable of responding to pressure increases under DEHC control.
4. 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 26.
5. For operation outside of nominal FWT, reduced FWT of up to 120°F is also supported for cycle operation through EOC subject to the restriction in Reference 11 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 FFTR. For a feedwater temperature reduction of between 30°F and 120 0 F, the reduced FWT limits should be applied.
6. A single MSIV may be taken OOS (closed) under any of the specified OOS Options if the core thermal power is maintained
  • 75% of 2957 MWth (Reference 13).
