==Subject:==
Core Operating Limits Report for Unit 3 Cycle 20 Revision 0 The purpose of this letter is to transmit the Core Operating Limits Report (COLR), Revision 0, for Dresden Nuclear Power Station (DNPS) Unit 3 operating cycle 20 (D3C20) in accordance with Technical Specifications Section 5.6.5, "CORE OPERATING LIMITS REPORT (COLR)."
The Unit 3 COLR was revised to utilize Westinghouse methodologies, which are approved by the NRC, for the transition to OPTIMA2 fuel and to support the reload design for Cycle 20.
Should you have any questions concerning this letter, please contact Mr. Jim Ellis at 815-416-2800.
Respectfully, Danny Bost Site Vice President Dresden Nuclear Power Station

: 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 analyzed for this cycle.
Licensed rated thermal power is 2957 MWth.
MCPR(P) and MCPR(F) values are independent of scram time.
LHGRFAC(P) and LHGRFAC(F) values are independent of scram time.
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, should be used unless otherwise indicated in the applicable table.
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.
For both Base and EOOS DLO/SLO conditions, for operation at NFWT, the OLMCPR limit is applicable to a variation of +100F/-30 0 F in feedwater temperature. For operation outside of NFWT, a feedwater temperature reduction of up to 120OF (RFWT) is also supported at rated conditions for Base and EOOS DLO/SLO conditions for cycle operation through EOC. This includes, but is not limited to, Feedwater Heaters OOS (FWHOOS) and Final Feedwater Temperature Reduction (FFTR). At off-rated conditions, the allowed feedwater temperature reduction is defined in Figure 9.2 of Reference 3. For a feedwater temperature reduction of between 30&deg;F and the allowable value (the "Minimum Feedwater Temperature Curve" as defined in Figure 9.2 of Reference 3), the RFWT limits should be applied.

Average Planar Linear Heat Generation Rate The MAPLHGR values for the most limiting lattice (excluding natural uranium) of each fuel type as a function of average planar exposure are given in Tables 3-1 and 3-2. During single loop operation, these limits are multiplied by the SLO multiplier listed in Table 3-3.

: 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% core thermal power, the OLMCPR as a function of core thermal power is shown in Tables 4-7 and 4-8. For operation at greater than 38.5% 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 4-6 by the applicable MCPR multiplier K(P) given in Tables 4-7 and 4-8. For operation at exactly 38.5% 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% core thermal power.
4.1.2. Flow-Dependent MCPR Tables 4-9 and 4-10 give the MCPR(F) limit as a function of the flow based on the applicable plant condition. The MCPR(F) limit determined from these tables is the flow dependent OLMCPR.
4.2. Automatic Flow Control MCPR Limits Automatic Flow Control MCPR Limits are not provided.
4.3. Scram Time TSSS, ISS, and NSS refer to scram speeds. TSSS is the Technical Specification Scram Speed, ISS is the Intermediate Scram Speed, and NSS is the Nominal Scram Speed.
The scram time values are shown in Table 4-1.
The NSS scram times are based on a conservative interpretation of scram time surveillance measurements. In the event that plant surveillance shows these scram insertion times to be exceeded, the MCPR limits are to default to the values which correspond to the ISS scram time. The ISS times have been chosen to provide an intermediate value between the NSS and TSSS, but the interpolation between these values is not supported by Westinghouse methodology. In the event that the ISS times are exceeded, MCPR limits for the TSSS apply.

Recirculation Pump Motor Generator Settings Cycle 20 was analyzed with a maximum core flow runout of 110%; therefore the recirculation pump motor generator scoop tube mechanical and electrical stops must be set to maintain core flow less than 110% (107.8 Mlb/hr) for all runout events (Reference 17). This value is consistent with the analyses of Reference 3.

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 Tables 5-1 through 5-16 and the minimum of: the power dependent LHGR Factor, LHGRFAC(P), or the flow dependent LHGR Factor, LHGRFAC(F). The LHGRFAC(P) is determined from Table 5-17, 5-18, or 5-19. The LHGRFAC(F) is determined from Table 5-20, 5-21, 5-22, 5-23, or 5-24.

The setpoint may be lower/higher and will still comply with the rod withdrawal error (RWE) analysis because RWE is analyzed unblocked.

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 A single MSIV may be taken OOS (shut) under any of the OOS Options, so long as core thermal power is maintained _<75% of 2957 MWth (Reference 3).
3 Each EOOS option except TBPOOS requires the opening profile for the Turbine Bypass Valves provided in Reference 8 to be met. These conditions also support 1 Turbine Bypass Valve OOS (TBPOOS) ifthe assumed opening profile (Reference 8) for the remaining 8 Turbine Bypass Valves is met. If the opening profile is not met with 8 or 9 operating Turbine Bypass Valves, or if more than one Turbine Bypass Valve is OOS, utilize the TBPOOS condition.
4 Coastdown    operation is defined as any cycle exposure beyond the full power, all rods out condition with plant power slowly lowering to a lesser value while core flow is held constant.
Coastdown analysis has been performed with bounding assumption of full power operation up to a cycle exposure of 16,338 MWD/MTU (or 16,450 MWD/MTU including FFTR).
r For operation with a Pressure Regulator Out-Of-Service (PROOS), the TCV Slow Closure limits should be applied. For operation with a PROOS and TCV Slow Closure, the TCV Slow Closure limits should be applied. For operation with a PROOS and PLUOOS, the PLUOOS limits should be applied. For operation with a PROOS and TCV Stuck Closed, the more restrictive of the flow-dependent limits (established by TCV Stuck Closed) and power dependent limits (established by TCV Slow Closure and PLUOOS limits) should be applied (Reference 3).
6 For operation with one Turbine Stop Valve Out-Of-Service (TSVOOS), the TCV Stuck Closed limits should be applied. Combination of one TSVOOS and TCV Stuck Closed is not analyzed (Reference 3).
7The   cycle specific stability analysis may impose restrictions on the Power-to-Flow map and/or restrict the applicable temperature for a reduction in feedwater temperature (RFWT) (Reference 15).
8 For both Base and EOOS DLO/SLO conditions, for operation at NFWT, the OLMCPR limit is applicable to a variation of +100F/-30 0F in feedwater temperature. For operation outside of Dresden Unit 3 Cycle 20

COLR Dresden 3 Revision 2                             Page 36 NFWT, a feedwater temperature reduction of up to 120OF (RFWT) is also supported at rated conditions for Base and EOOS DLO/SLO conditions for cycle operation through EOC. This includes, but is not limited to, Feedwater Heaters OOS (FWHOOS) and Final Feedwater Temperature Reduction (FFTR). At off-rated conditions, the allowed feedwater temperature reduction is defined in Figure 9.2 of Reference 3. For a feedwater temperature reduction of between 30&deg;F and the allowable value (the "Minimum Feedwater Temperature Curve" as defined in Figure 9.2 of Reference 3), the RFWT limits should be applied.
9 Asymmetric inlet enthalpy distribution produced by RWCU injection does not have a substantial impact on thermal limits; therefore no adjustments to the thermal limits are required (Reference 3).
