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/- 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 the Reload Licensing Report (Reference 3). 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. Nominal FWT is defined and described in detail in Section 9 of the Reference 3 Reload Licensing Report.Quad Cities Unit 1 Cycle 20 COLR Quad Cities 1 Revision 2 Page 8 1 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 4-11.For Optima2 fuel, lattice-specific MAPLHGR values for DLO and SLO are provided in Tables 4-2 through 4-10. Table 4-4 provides only the most limiting set of MAPLHGR limit from Reference 3 for Lattice 105, which is part of two types of Optima2 fuel bundles. The MAPLHGR limits for the top and bottom natural uranium lattices (lattices 101 and 108) will be set equal to the most restrictive MAPLHGR limits for the other lattice types.Table 4-1 MAPLHGR for bundle(s):

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% of rated core thermal power, the OLMCPR as a function of core thermal power (MCPR(P))
is shown in Tables 5-8 and 5-9. 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 5-2 through 5-7 by the applicable MCPR multiplier K(P) given in Table 5-8 and 5-9. 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.5.1.2. Flow-Dependent MCPR Tables 5-10 through 5-13 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.5.2. Automatic Flow Control MCPR Limits Automatic Flow Control MCPR Limits are not provided.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. Reference 3 indicates that TSSS control rod insertion time values used in the analysis are conservative in comparison to the values 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.

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 7).GE14-P1ODNAB409-i7GZ-10OT-145-T6-2825 GE14-P1ODNAB408-15GZ-10OT-145-T6-2826 GE14-P1ODNAB194-4G7.0-10OT-145-T6-2647 GE14-P1ODNAB411-14GZ-10OT-145-T6-2564 GE14-P1ODNAB409-15GZ-10OT-145-T6-2565 The thermal mechanical operating limit at rated conditions for the Optima2 fuel is established in terms of the maximum LHGR given in Table 6-12 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 6-12 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 6-13, 6-14, and 6-15. The LHGRFAC(F) is determined from Table 6-16 through 6-20.Table 6-1: LHGR Limit for GEl4- PlODNAB411-14GZ-10OT-145-T6-2564 (Reference 5)Lattices 5567, 5568, 5569, 5570, 5572 and 5573 LHGR Limit kW/ft

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.

- 16) for utilizing SUBTIP methodology aremet and up to 50% of the LPRMs OOS with an LPRM calibration frequency of 2500 Effective Full Power Hours (EFPH) (2000 EFPH +25%). 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 11 (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 21 to be met. These conditions also support Turbine Bypass flow of 29.6% of vessel rated steam flow, equivalent to 1 Turbine Bypass Valve OOS (or partially closed Turbine Bypass Valves equivalent to 1 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 can not pass an equivalent of 29.6%of vessel rated steam flow, 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 16,569 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, so long as core thermal power is maintained
<75% of 2957 MWth (Reference 3).7 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 11.8 For Base DLO and Base SLO cases, as well as all EOOS conditions, operation for both nominal FWT 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 +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 3 report.9 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 an analyzed out-of-service combination.
10 For operation with a PROOS and TCV Stuck Closed, or for operation with a PLUOOS and TCV Stuck Closed, apply 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).
