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 (ICF) is fully evaluated for this cycle, however, flow cannot exceed 103.4% rated flow due to unit specific limitations. Licensed rated thermal power is 2957 MWth. For allowed operating regions, see applicable power/flow map.

Coastdown is defined as any cycle exposure beyond the full power, rated 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.

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

All thermal limits are analyzed to NSS, ISS, and TSSS, except for the special case of Base Case thermal limits with TBV#8 and one additional Turbine Bypass Valve OOS, which is only analyzed for NSS (Reference 23). 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 and 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 The Operating Limit Minimum Critical Power Ratios (OLMCPRs) for D2C24 were established to protect the Safety Limit Minimum Critical Power Ratio (SLMCPR) for the abnormal operational occurrences. The SLMCPR values for DLO and SLO for D2C24 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 (i.e., D2C23).

In determining the SLMCPR values for D2C24, 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 12 and 14). The application of these methodologies was previously approved by the NRC in license amendment 224 to Renewed Facility Operating License DPR-19 (Reference 18).

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 MCPR(F) limit determined from this table is the flow dependent OLMCPR.

Dresden Unit 2 Cycle 24

COLR Dresden 2 Revision 14 Page 37 of 54 4.2. Scram Time TSSS, ISS, 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 documents 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, 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, 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, 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 fully inserted (notch 00) can be conservatively included for calculation of core average scram speed. (Reference 22)

Table 4-1 Scram Times (References 5 and 22)

Control Rod Insertion Fraction TSSS (seconds) ISS (seconds) NSS (seconds) 5 0.48 0.360 0.324 20 0.89 0.720 0.700 50 1.98 1.580 1.510 90 3.44 2.740 2.635 4.3. Recirculation Pump ASD Settings Cycle 24 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 8). This value is consistent with the analyses in Reference 22.

5. Linear Heat Generation Rate The thermal mechanical operating limit (TMOL) at rated conditions is established in terms of the maximum LHGR given in Table 5-1, Table 5-2, Table 5-3 or Table 5-4 as a function of rod nodal (pellet) exposure. The Table 5-1 limits apply to fresh Optima2 bundle designs for the Cycle 22 reload, the Table 5-2 limits apply to fresh Optima2 bundle designs for the Cycle 23 reload, and the Table 5-3 limits apply to fresh Optima2 bundle designs for the Cycle 24 reload. The Table 5-4 limits apply to the natural Uranium blankets at the top and bottom of all fuel types. The limits changed for the Cycle 24 fresh fuel due to the reanalysis of the TMOL basis. The natural Uranium lattices 81 and 89 are monitored with the updated TMOL LHGR limit for Gad rods (Reference 21).

The linear heat generation rate (LHGR) limit is the product of the exposure dependent LHGR limit from either Table 5-1, Table 5-2, Table 5-3, or Table 5-4 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 Table 5-5, as applicable. The LHGRFAC(F) is determined from Table 5-6.

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.

Dresden Unit 2 Cycle 24

COLR Dresden 2 Revision 14 Page 50 of 54 Common Notes - Applicable to both Base Case and all EOOS Combinations for DLO/SLO:

1. All modes are allowed for operation at MELLLA, ICF (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 16277 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 OOS Option may be combined with each of the following conditions provided the requirements of References 19 and 20 are met:
  • A maximum of 18 TIP channels OOS (Up to 2 common TIP channels may be OOS, in combination with a maximum of 16 TIP channels OOS in locations outside of the common TIP channel location of 32-33).
  • 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 30F and 120F is supported for Base Case and all EOOS DLO/SLO conditions, except for the TBV#8 and one additional TBV OOS EOOS condition, for cycle operation through EOC subject to the restriction in Reference 4 for feedwater temperature reductions of greater than 100 OF. The restriction requires that for a FWT reduction greater than 1O0F, 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) OOS, with the remaining 8 TBVs meeting the assumed opening profile in Reference 7. The analyses also support Turbine Bypass flow of 3.456 MIb/hr of vessel rated steam flow, equivalent to one TBV OOS (or partially closed TBVs equivalent to one closed TBV), if the assumed opening profile (Reference 7) for the remaining TBVs is met. The Base Case, NFWT, NSS, analysis supports Turbine Bypass Valve #8 and any one additional Turbine Bypass Valve OOS, with the remaining 7 TBV meeting the assumed opening profile in Reference 7 (Reference 23). 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 TBV#8 and any one additional TBVOOS EOOS option is not being used, or if operating with more than one TBV OOS with RFWT, ISS, or TSSS, utilize the TBVOOS condition.
4. If any TBVs are OOS 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. For all cases, except TBVOOS and TBV#8 and any one additional TBV OOS, the equivalent of 8 of 9 TBVs (as stated in Note 3 above) are required to fast open on TSV closure. For TBV#8 and any one additional TBV OOS, the equivalent of 7 of 9 TBVs (as stated in note 3 above) are required to fast open on TSV closure. The TBVOOS condition assumes that all of the TBVs do not fast open on TSV closure or on a TCV fast closure event.
5. A single MSIV may be taken OOS (shut) under all OOS 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.
