2. General Information This report is prepared in accordance with Technical Specif1cat1on 5 6.5 The D2C27 reload is licensed by Framatome However, some legacy analyses by Westinghouse are still applicable for OPTIMA2 fuel as descnbed in Reference 9.

Licensed rated thennal power 1s 2957 MWth. Rated core flow is 98 Mlb/hr. Operation up to 108% rated core flow is licensed for this cycle; however, core flow cannot exceed 103.4% rated core flow due to unit specific limitations. For allowed operating regions, see applicable power/flow map.

The licensing analysis supports full power operation to EOCLB (38,198 MWcl/MTU CAVEX). Note that this value includes coastdown, where full power operation is not expected. The transient analysis limits are provided for operation *up to specific CAVEX exposures as defined in Section 4.3.

Coastdown 1s defined as operation beyond EOFPL (37,411 MWd/MTU CAVEX) with the plant power gradually reducing as available core reactivity diminishes The D2C27 reload analyses do not credit this reduced power during coastdown and the EOCLB limits remain valid for operation up to rated power. The minimum allowed coastdown power level is 40% rated CTP per Reference 1 Power and flow dependent limits are listed for various power and flow levels. Linear interpolation on power and flow (as applicable) is to be used to find intennediate values Linear interpolation is also to be used for table items intentionally left blank, as indicated by boxes which are grayed out.

Only MCPRp varies with scram speed All other thennal limits are analyzed to remain valid with NSS, ISS, and TSSS.

LHGRFACr is independent of feedwater temperature and .,EOOS conditions For thennal limit monitoring above 100% rated power or 108% rated core flow, the 100% rated power or the 108% core flow thennal limrt values, respectively, shall be used. Steady state operation 1s not allowed in this region Limits are provided for transient condrt1ons only.

OLMCPR values contained herein support operation with a TLO SLMCPR of 1.12 and a SLO SLMCPR of 1.14 through EOFPL. These safety limits are consistent with those contained in Technical Specrfication 2.1.1.2. Additionally, OLMCPR values contained herein support operation with a TLO SLCMPR of 1.08 and a SLO SLMCPR of 1 10 through EOCLB. These safety limits are consistent with those requested in Reference 13. The OLMCPR values corresponding to the safety limits requested in Reference 13 cannot be used for core monitonng until the amendment authorizing the use of these safety limits has been implemented by Dresden Station.

3. Average Planar Linear Heat Generation Rate Technical Specrf1cat1ons Sections 3.2.1 and 3.4.1 Table 3-1 provides the MAPLHGR SLO multipliers for ATRIUM 10XM and OPTIMA2 fuel. For OPTIMA2 natural uranium lattices, TLO and SLO MAPLHGR values are provided in Table 3-2. For all other OPTIMA2 lattices, lattice-specific MAPLHGR values for.TLC are provided in Tables 3-3 through 3-21.

For ATRIUM 10XM fuel, the MAPLHGR values applicable for all lattices can be found in Table 3-22.

During SLO, the limits in Tables 3-3 through 3-22 are multiplied by the fuel-spec1f1c SLO multiplier listed in Table 3-1. The ATRIUM 10XM multiplier may be applied to OPTIMA2 for SLO conditions, as the ATRIUM 10XM multiplier is more limiting Table 3-1: MAPLHGR SLO Multipliers (References 7 and 9)

4. Operating Limit Minimum Critical Power Ratio Technical Specification Sections 3.2 2, 3A1, and 3.7.7 The OLMCPRs for D2C27 were established so that less than 0.1 % of the fuel rods in the core are expected to experience boiling transrt1on dunng an AOO inrt1ated from rated or off-rated condrt1ons and are based on the Technical Specifications SLMCPR values (References 9 and 12).

Exelon submitted a license amendment request (Reference 13) to the NRC in December 2018 requesting that the TLO SLMCPR be reduced from 1 12 to 1.08 and that the SLO SLMCPR be reduced from 1 14 to 1.10. Therefore, OLMCPRs are included in this section to support both sets of SLM CPR values. In addition, Table 8-1 includes penalties that will allow the use of certain OLMCPRs corresponding to the new SLMCPR values as long as the MFLCPR limit is reduced from 1.0 by the amount indicated in Table 8-1 Tables 4-3 through 4-30 include MCPR limits for various specified SLMCPR values and EOOS conditions.

The EOOS conditions separated by "i in these tables represent single EOOS conditions and not any combination of conditions. Refer to Section 8 for a detailed explanation of allowable combined EOOS conditions.

4.1. Manual Flow Control MCPR Limits The OLMCPR 1s 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 The OLMCPR as a function of core thermal power (MCPRp) is shown in Tables 4-3 through 28 MCPRp limits are dependent on supported SLMCPR values, scram times as described in Section 4.2, exposure as described in Section 4.3, fuel type, FWT, and whether the plant is in TLO or SLO. TLO limits for ATRIUM 10XM fuel and OPTIMA2 fuel associated with a SLMCPR of 1.12 are given in Tables 4-3 through 4-8. SLO limits for ATRIUM 10XM fuel and OPTIMA2 fuel associated with a SLMCPR of 1 14 are given in Tables 4-9 and _4-10 TLO limits for ATRIUM 1OXM fuel associated with a SLMCPR of 1.08 are given in Tables 4-11 through 4-16. SLO limits for ATRIUM 10XM fuel associated with a SLMCPR of 1.10 are. given in Tables 4-23 through 4-25. TLO limits for OPTIMA2 fuel associated with a SLMCPR of 1 08 are given in Tables 4-17 through 4-22. SLO limits for OPTIMA2 fuel associated wrth a SLMCPR of 1 10 are given in Tables 4-26 through 4-28 4.1.2. Flow-Dependent MCPR Tables 4-29 and 4-30 give the OLMCPR limit as a function of the flow (MCPRt) based on the supported SLMCPR values and applicable plant cond1t1on. Limrts for a TLO SLMCPR of 1.12 and a SLO SLMCPR of 1.14 are given in Table 4-29. Limits for a TLO SLMCPR of 1.08 and a SLO SLMCPR of 1.10 are given in Table 4-30 These values are applicable to both ATRIUM 10XM and OPTIMA2 fuel.

COLR Dresden 2 Revision 18 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 Specrf1cat1ons (Reference 2)

To utilize the OLMCPR limits for NSS in Tables 4-3, 4-6, 4-7, 4-9, 4-11, 4-14, 4-17, 4-20, 4-23, and 4-26, 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 utirize the OLMCPR limits for ISS in Tables 4-8, 4-10, 4-12, 4-15, 4-18, 4-21, 4-24, and 4-27, 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.

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. Conservative adjustments to the NSS and ISS scram speeds were made to the analysis inputs to appropriately account for the effects of 1 stuck control rod and one additional control rod that 1s assumed to fail to scram (Reference 9).

To utilize the OLMCPR limrts for TSSS in Tables 4-4, 4-5,'4-13, 4-16, 4-19, 4-22, 4-25, and 4-28, the control rod insertion time of each operable control rod at each control rod insertion fraction must be less than or equal to the TSSS time shown in Table 4-1 below. The Technical Specrf1cations allow operation with up to 12 "slow" and 1 stuck control rod One add1t1onal control rod is assumed to fail to scram for the system transient analyses performed to establish MCPRp limits (Reference 9) Conservative adJustments to the TSSS scram speeds were made to the analysis inputs to appropnately account for the effects of the slow and stuck rods on scram reactivity (Reference 9).

For cases below 38.5% power (Pt,ypass}, the results are relatively insensitive to scram speed, and only TSSS analyses ware performed (Reference 9).

COLR Dresden 2 Revision 18 4.3. Exposure Dependent MCPR Limits Exposure-dependent MCPRp limits were established to support operation from BOC to EOFPLB (CAVEX of 37,411 MWd/MTU) and EOFPLB to EOCLB (CAVEX of 38,198 MWd/MTU) as defined by the CAVEX values listed in Table 4-2. Note that the thermal limits are based on CAVEX. The limits at a later exposure range can be used earlier in the cycle as they are the same or more conservative.

therefore, the recirculation pump ASD must be set to maintain core flow less than 110%

5. Linear Heat Generation Rate Technical Specificatjon Sections 3,2 3, 3.4,1, and 3,7.7 The TMOL at rated conditions for the OPTIMA2 and ATRIUM 10XM fuel is established in terms of the maximum LHGR as a function of peak pellet (rod nodal) exposure. The LHGR limits for OPTIMA2 fuel are presented in Tables 5-1 through 5-5. The limits in Tables 5-1 and 5-5 apply to OPTIMA2 lattices that do not require Gadolm1a set down penalties. The limits in Tables 5-2 through 5-4 apply to OPTIMA2 lattices that do require Gadolinia set down penalties. The limits in Table 5-5 apply to the OPTIMA2 natural U blank~ts in lattices 81 and 89. The LHGR limrts for ATRIUM 1OXM fuel are _presented in Table 5-6.

The power- and flow-dependent LHGR multipliers (LHGRFACp and LHGRFACr) are applied directly to the LHGR limits to protect against fuel melting and overstraining of the cladding during an AOO (Reference 9).

In all conditions, the margin to the LHGR limits is determined by applying the lowest multiplier from the applicable LHGRFACp and LHGRFACt multipliers for the power/flow statepoint of interest to the steady state LHGR limit (Reference 9).

LHGRFACp and LHGRFACt multipliers were established to support base case and all EOOS conditions for all Cycle 27 exposures and scram speeds The LHGRFACp multipliers for ATRIUM '10XM and OPTIMA2 are presented in Table 5-7 and Table 5-8, respectively. The LHGRFACr multipliers for ATRIUM 10XM and OPTIMA2 are presented in Table 5-9 and Table 5-10, respectively

8. Modes of Operation The allowed modes of operation with combinations of EOOS are as described in Tables 8-1 and 8-2. The EOOS conditions separated by *r in these tables represent single EOOS conditions and not combinations of conditions.

Table 8-1 provides the EOOS options which have been analyzed for a TLO SLMCPR of 1.12 and a SLO SLMCPR of 1 14 and for which MCPR operating limits were calculated or evaluated. For some EOOS options, MCPR operating limits have not been explicrtly calculated for these SLMCPR values; instead, the MCPR operating limits that were calculated to correspond to a TLO SLMCPR of 1.08 and a SLO SLMCPR of 1 10 can be used if the MFCLPR limit of 1 0 1s reduced by the corresponding MFLCPR penalty shown in Table 8-1, creating an administrative MFLCPR hmrt of less than 1.0. Operation with the EOOS options which do not appear in Table 8-1 have not been analyzed for Cycle 27 for a TLO SLMCPR of 112 and a SLO MFLCPR of 1.14, so operation with these EOOS options is not allowed as long as these are the SLMCPR values reflected in the Technical Specifications.

Table 8-2 provides the EOOS options which have been analyzed for a TLO SLMPCR of 1.08 and a SLO SLMCPR of 1.10 and for which MCPR operating limits were calculated. Operation with the EOOS options shown in Table 8-2 is allowed and there are no MFLCPR penalties required if the Technical Specifications reflect a TLO SLCMPR of 1.08 and a SLO SLMCPR of 1.10.

Note that the following EOOS options have operational restrictions: all SLO, all EOOS options with 1 TCV/TSV stuck closed, and MSIVOOS. See Table 8-3 for specific restrictions.

COLR Dresden 2 Revision 18 Common Notes.

1 All modes are allowed for operation at MELLLA, ICF (up to 108% r1ted core flow but subject to the restnct1ons in Section 2), and coastdown subject to the power restrictions in Table 8-3 (Reference 9)

The licensing analysis supports full power operation to EOCLB (38,198 MWd/MTU CAVEX). Note that this value includes coastdown, where full power operation is not expected The minimum allowed coastdown power level is 40% rated CTP per Reference 1 Each OOS Option may be combined with each of the following conditions (Reference 9):

a. Up to 40% of the TIP channels OOS or the equivalent number of TIP channels, using the guidance in Reference 4 for startup wrth TIP machines OOS

b. Up to 50% of the LPRMs OOS c An LPRM calibration frequency of up to 2500 EFPH

2. Nominal FWT results are valid for application within a +10°F/-30°F temperature band around the nominal FWT curve (Reference 9). For operation outside of nominal FWT, a FWT reduction of between 30°F and 120°F is supported for all FHOOS condrt1ons listed in Tables 8-1 and 8-2 for cycle operation through EOCLB (Reference 9). At lower power levels, the feedwater temperature reduction is less (Reference 9). Per Reference 5, there 1s a restriction which requires that for a FWT reduction greater than 1OG°F, operation needs to be restricted to less than the 100% rod line. For a feedwater temperature reduction of between 30°F and 120°F, the FHOOS limits should be applied.

3. The base case and EOOS limrts and multipliers support operation wrth 8 of 9 turbine bypass valves operational (1.e., one bypass valve out of service) with the exception of the TBVOOS condition in which all bypass valves are inoperable (Reference 9) Use of the response curve in TRM Appendix H supports operation with any single TBV OOS TRM Appendix H fac1lrtates analysis with one valve OOS in that the capacity at 0.5 seconds from start of TSV closure is equivalent to the total capacity wrth eight out of the nine valves in service (Reference 10). The analyses also support Turbine Bypass flow of 29.8% of vessel rated steam flow (Reference 10), equivalent to one TBV OOS (or partially closed TBVs equivalent to one closed TBV), rf 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. TBVOOS assumes that ALL the TBVs do n..Q! trip open on TCV fast closure or TSV closure and that ALL the TBVs are not capable of opening via the pressure control system (Reference 11) Steam relief capacity is defined in Reference 10.

5. Between 25% and 50% of rated thermal power, the PLUOOS/TCV Slow Closure thermal limit set ensures-that the AOO acceptance cnteria are met for a load reJection event if the 86 Device is OOS (Reference 9). Therefore, use the PLUOOS/TCV Slow Closure thermal limit set between 25% and 50% of rated thermal power if the 86 Device is OOS Page 67 of 71
