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 analyzed but not licensed for this cycle. Licensed rated thermal power is 2957 MWth. For allowed operating regions, see applicable power/flow map.

The licensing analysis supports full power operation to 15911 MWd/MTU and coastdown to a power level of 70%, given all burnup limits are satisfied. (Reference 3)

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.

The OLMCPR multiplier and MCPR(F) values are independent of scram speed.

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

All thermal limits are analyzed to NSS, ISS, and TSSS. 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, shall be used.

3. Average Planar Linear Heat Generation Rate For natural uranium lattices, DLO and SLO MAPLHGR values are provided in Table 3-2. For all other lattices, lattice-specific MAPLHGR values for DLO are provided in Tables 3-3 through 3-44. During single loop operation, these limits are multiplied by the SLO multiplier listed in Table 3-1.

4. Operating Limit Minimum Critical Power Ratio The Operating Limit Minimum Critical Power Ratios (OLMCPRs) for D3C23 were established to protect the Safety Limit Minimum Critical Power Ratio (SLMCPR) for the abnormal operational occurrences. The SLMCPR values for DLO and SLO were determined to be 1.12 and 1.14, respectively (Reference 12).

In determining the SLMCPR values for D3C23, Westinghouse applied the methodologies from CENPD-300-P-A, consistent with the manner specified in Limitations 1 through 6 and-8 of the NRC SER approving CENPD-300-P-A (References 12 and 13). The application of these methodologies was previously approved by the NRC in license amendment 213 to Renewed Facility Operating License DPR-25 (Reference 14).

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 3 Cycle 23

COLR Dresden Unit 3 Revision 8 Page 48 of 64 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 15). Reference 3 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 3)

Recirculation Pump ASD Settings Cycle 23 was analyzed with a maximum core flow runout of 110% (Reference 16); therefore the recirculation pump ASD must be set to maintain core flow less than 110% (107.8 Mlb/hr) for all runout events. This value is consistent with the analyses in Reference 3.

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 and Table 5-2 as a function of rod nodal (pellet) exposure. The Table 5-1 limits apply to Optima2 bundle designs for the Cycle 21 and Cycle 22 reloads and natural Uranium lattices in Cycle 23 bundle designs. The Table 5-2 limits apply to enriched lattices in Optima2 bundle designs for the Cycle 23 reload (Reference 23).

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

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 3 Cycle 23

COLR Dresden Unit 3 Revision 8 Page 60 of 64 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), and coastdown subject to the power restrictions in Table 8-2. Either EOC must be reached or coastdown must begin prior to exceeding 15911 MWd/MTU. The licensing analysis remains valid down to a coastdown power level of 70% given all burnup limits are satisfied per Methodology 7. Each OOS Option may be combined with each of the following conditions provided the requirements of References 18 and 19 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 (Reference 20) and within the operating steam dome pressure region (Reference 20). The FWTR results are valid for the minimum FWT curve (Referencem20). For operation outside of NFWT, a FWTR of between 30F and 120F is supported for Base Case and all EOOS DLO/SLO conditions for cycle operation through EOC subject to the restriction in Reference 21 for feedwater temperature reductions of greater than 100 OF. The restriction requires that for a FWT reduction greater than 10OF, 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 22. The analyses also support Turbine Bypass flow of 29.8% of vessel rated steam flow, equivalent to one TBV OOS (or partially closed TBVs equivalent to one closed TBV), if the assumed opening profile for the remaining TBVs is met. If the opening profile is NOT met, or if the TBV system cannot pass an equivalent of 29.8% of vessel rated steam flow, utilize the TBVOOS condition.
4. For all cases analyzed including TBVOOS, equivalent of 2 of the first 3.6 TBVs must be capable of opening via the pressure control system while Turbine Bypass Valves #5-9 are allowed to be OOS.

For all cases except TBVOOS, the equivalent of 8 of 9 Turbine Bypass Valves (as stated in Note 3 above) are required to trip open on TCV fast closure or on TSV closure. The TBVOOS condition assumes that all of the TBVs do not trip open on TCV fast closure or on TSV closure.

5. A single MSIV may be taken OOS (shut) under any of the specified OOS options as long as core thermal power is maintained < 75% of 2957 MWth (Reference 3).
