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 operation is defined as cycle exposure beyond the full power, full flow, and all rods out condition with the plant power gradually reducing as available core reactivity diminishes.

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

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

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.

3. Average Planar Linear Heat Generation Rate Lattice-specific MAPLHGR values for DLO and all EOOS conditions except SLO are provided in Tables 3-2 through 3-33. During single loop operation, these limits are multiplied by the EOOS multiplier listed in Table 3-1.

4. Operating Limit Minimum Critical Power Ratio 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 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 higher of either of the two 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 Cycle 21 Revision 0 4.3. Scram Time TSSS, ISS, and NSS refer to scram speeds. The scram time values 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 12). 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.

Recirculation Pump ASD Settings Cycle 21 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 9). This value is consistent with the analyses of Reference 3.

5. Linear Heat Generation Rate The thermal mechanical operating limit at rated conditions for the Optima2 fuel is established in terms of the maximum LHGR given in Table 5-1 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 Table 5-1 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 5-2.

For operation at exactly 38.5% of rated core thermal power, the LHGRFAC(P) as a function of core thermal power is the lower of either of the two multipliers evaluated at 38.5% of rated core thermal power.

The LHGRFAC(F) is determined from Table 5-3, and is applicable for all EOOS conditions.

Operation 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%.

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.

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 14 (Reference 3). 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), ifthe assumed opening profile for the remaining Turbine Bypass Valves is met. If the opening profile is NOT met, or ifthe Turbine Bypass Valve system cannot pass an equivalent of 29.6% of vessel rated steam flow, utilize the TBVOOS condition.

3. 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 (Reference 9).
4. For operation outside of Nominal FWT, a feedwater temperature reduction of up to 120OF is supported for Base and EOOS DLO/SLO conditions for cycle operation through EOC subject to the restriction in Reference 11 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 0F. 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.
5. For all cases including TBVOOS, 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. For all cases except TBVOOS, 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. 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.
6. A single MSIV may be taken OOS (shut) under all OOS Options, as long as core thermal power is maintained 5 75% of 2957 MWth (Reference 3).

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 the 75% of rated core thermal power requires raising the MCFL setpoint and/or increasing TBV availability to increase the available total reactor vessel steam flow capability.
