COLR Dresden 2 Revision 15

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.

Licensed rated thermal power is 2957 MWth. Rated core flow is 98 Mlb/hr. Operation up to 108%

rated flow (ICE) is fully evaluated for this cycle; however, flow cannot exceed 103.4% rated flow due to unit specific limitations. For allowed operating regions, see applicable power/flow map.

The licensing analysis supports full power operation to EOFPL + 25 days (16182 MWD/MTU) and coastdown to a power of 70% given all burnup limits are satisfied (Reference 22).

Coastdown is defined as any cycle exposure beyond the full power, licensed increased core 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 speed. MCPR(F) is independent of FWT.

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

All thermal limits are analyzed to NSS, ISS, and TSSS, except for the special case 2TBVOOS, which is only analyzed for NSS and NEWT (Reference 22). Only MCPR operating limits vary with scram speed.

For thermal limit monitoring above 100% rated power or 100% rated core flow, the 100% rated power or the 100% core flow thermal limit values, respectively, can be used unless otherwise indicated in the applicable table.

4. Operating Limit Minimum Critical Power Ratio Technical Specification Sections 3.2.2. 3.4.1. and 3.7.7 The OLMCPRs for D2C25 were established to protect the SLMCPR for abnormal operational occurrences. The SLMCPR values for DLO and SLO for D2C25 were determined to be 1.12 and 1.14 (Reference 22), respectively, which are unchanged from the NRC-approved values for the previous operating cycle (D2C24).

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 or equal to 38.5% core thermal power, the power dependent OLMCPR is shown in Tables 4-8 and 4-9. For operation at greater than 38.5% core thermal power, the power dependent OLMCPR is determined by multiplying the applicable rated condition OLMCPR limit shown in Tables 4-2 through 4-7 by the applicable OLMCPR multiplier given in Tables 4-8 and 4-9.

4.1.2. Flow-Dependent MCPR Table 4-10 gives the MCPR(F) limit as a function of the flow based on the applicable plant condition. The flow-dependent OLMCPR values are applicable to all base case and EOOS combinations.

COLR Dresden 2 Revision 15 4.2. Scram Time TSSS, 1SS, 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 5). Reference 22 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 OLMCPR limits for NSS in Tables 4-6 and 4-7, 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 and 4-5, 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.

To utilize the OLMCPR limits for TSSS in Tables 4-2 and 4-3, the average control rod insertion time at each control rod insertion fraction must be equal to or less than the TSSS 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. The time for inoperable drives fully inserted (notch 00) can be conservatively included for calculation of core average scram speed. (Reference 22)

This value is consistent with the analyses in Reference 22.

5. Linear Heat Generation Rate Technical Specification Sections 3.2.3 and 3.4.1 The TMOL at rated conditions is established in terms of the maximum LHGR given in Table 5-1 through Table 5-7 as a function of rod nodal (pellet) exposure. The Table 5-1 through Table 5-5 limits apply to fresh Optima2 bundle designs for the Cycle 23 reload and the Table 5-6 limits apply to fresh Optima2 bundle designs for the Cycle 24 and Cycle 25 reloads. The Table 5-7 limits apply to the natural Uranium blankets at the top and bottom of all fuel types.

The LHGR Limit for Gadolinia Rods values in Table 5-6 apply to the entire length of enriched fuel for any rod that contains Gadolinia anywhere in the fuel rod for the Cycle 24 and Cycle 25 fuel.

(Reference 22).

The LHGR limit is the product of the exposure dependent LHGR limit from Table 5-1 through Table 5-7 as appropriate and the minimum of the power dependent LHGR Factor, LHGRFAC(P),

and the flow dependent LHGR Factor, LHGRFAC(F). The LHGRFAC(P) is determined from Table 5-8. The LHGRFAC(F) is determined from Table 5-9, and is applicable for DLO, SLO, and all Base Case and EOOS conditions.

I Corresponding Maximum 1.15 16 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.

- EOOS condition has identical thermal limits as the Base Case. Therefore, this condition will use the Base Case thermal limit set.

Page 51 of 55

COLR Dresden 2 Revision 15 Common Notes - Applicable to both Base Case and all EOOS Combinations for DLO/SLO:

1. All modes are allowed for operation at MELLLA, ICE (up to 108% rated core flow but subject to the restrictions in Section 2), and coastdown (subject to restrictions in Table 8-2). Either EOC must be reached or coastdown must begin prior to reaching 16182 MWd/MTU. The licensing analysis remains valid down to a coastdown power level of 70% given all burnup limits are satisfied per Methodology 6. Each 003 Option may be combined with each of the following conditions provided the requirements of Reference 19 is met:

A maximum of 18 TIP channels 003 (Up to 2 common TIP channels may be 003, in combination with a maximum of 16 TIP channels 003 in locations outside of the common TIP channel location of 32-33).

Up to 50% LPRMs 003

An LPRM calibration frequency of up to 2500 EFPH (2000 EFPH + 25%)

2. Nominal FWT results are valid for application within a +10°F/-30°F temperature band around the nominal FWT curve and operating steam dome pressure region bounded by the maximum value of 1020 psia and the minimum pressure curve (Reference 8). The FWTR results are valid for the minimum FWT curve (Reference 22). For operation outside of NFWT, a FWTR of between 30°F and 120°F is supported for Base Case and all EOOS DLO/SLO conditions, except for 2TBVOOS, for cycle operation through FOC subject to the restriction in Reference 4 for feedwater temperature reductions of greater than 100°F. The restriction requires that, for a FWT reduction greater than 100°F, operation needs to be restricted to less than the 100% load line.

3. All analyses support the fastest Turbine Bypass Valve (assumed to be #1) 003, with the remaining 8 TBVs meeting the assumed opening profile in Reference 7. The analyses also support Turbine Bypass flow of 3.456 Mlb/hr of vessel rated steam flow, equivalent to one TBV 003 (or partially closed TBVs equivalent to one closed TBV), if the assumed opening profile (Reference 7) for the remaining TBVs is met. If the opening profile is NOT met, or if the TBV system cannot pass an equivalent of 3.456 Mlb/hr of vessel rated steam flow and the 2TBVOOS FOOS option is not being used, utilize the TBVOOS condition (Reference 22).

4. The 2TBVOOS with NSS and NEWT analysis supports Turbine Bypass Valve #8 and any one additional Turbine Bypass Valve 003, with the remaining 7 TBV meeting the assumed opening profile in Reference 7. If operating with more than one TBV 003 with RFWT, ISS, or TSSS, utilize the TBVOOS condition (Reference 22).

5. If any TBVs are 003 in the pressure control mode, the maximum steam flow removal capacity for pressure control needs to be evaluated to ensure that at least the equivalent of two TBVs are capable of being opened for pressure control within the limits of the MCFL (Reference 22).

6. A single MSIV may be taken 003 (shut) under all 003 Options, as long as core thermal power is maintained < 75% of 2957 MWth (Reference 22).

- - Operation above 75% rated power is included as part Of the reload analysis. However, operation above 75% power may require raising the MCFL setpoint to increase the available total reactor vessel steam flow capability. Information regarding the steam flow capability necessary to satisfy the reload analysis for operation above 75% power is reported in Reference 22.
