COLR Dresden 2 Revision 12 Page 30 of 45 4.3. Scram Tim.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 am 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 lmits 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 Interpolation between these values is not supported by Westinghoose mehodology.

General Information Power and flow dependent limits are listed for various power and flow levels. Unear Interpolation Is to be used to find Intermediate values.Rated core flow Is 98 MIb/hr. Operation up to 108%/* rated flow (lCF) is fully evaluated for this cycle, however, flow cannot exceed 103.4% rated flow due to unit specific limitations.

Ucensed 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 ail 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. Only MCPR operating limit. 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.Westinghouse methods used in slow and fast transient analyses as well as SLMCPR calculations are sufficient to cover the small effect of Vhe asymmetric feedwater temperature for all modes of operation as supported by the reload analysis.

Therefore, all thermal limits for all fuel types with all flexibility and EOOS options remain valid with respect to the effect of the asymmetric feedwater temperature (Reference 13).

COLR Dresden 2 Revision 12 Page 8 of 45 3. Average Planar Linear Neat Generation Rate For natural uranium lattices, DLO and SLO MAPLHGR values are provided in Table 3-1. For all other lattices, lattice-specific MAPLHGR values for DLO are provided In Tables 3-2 through 3-42.During single loop operation, these limits are multiplied by the SLO multiplier listed In Table 3-43.Unlike previous cycles, the MAPLHGR limits for the top and bottom natural uranium lattices (lattices 81 and 89) are now set by their own limits in Table 3-1, and are no longer an aggregate based upon the most restrictive value at each exposure of all lattices.

Table 3-2 uses the updated limits provided In Reference 11, which supersede the limits provided In the odginal RLR documented In Reference 3.TaWie 3-1 MAPLHGR for uNid~stamw.

Operating Limit Minimum Critical Power Ratio The Operating Limit Minimum Critical Power Ratios (OLMCPRe) for 02C23 were established to protect the Safety Limit Minimum Criica Power Ratio (SLMCPR) for the abnormal operational occurrences.

The SLMCPR values for DLO and SLO for 02C23 were determined to be 1.12 and 1.14 (Reference 13), respectively, which are unchanged from the NRC-approved values for the previous operating cycle (I.e., 02C22).In determining the SLMCPR values for D2C23, Westinghouse appled the methodologies from CENPD-300-P.A, consistent with the manner specified in Limitations I through 6 and 8 of the NRC Safety Evaluation Report (SER) approving CENPD-300-P-A (References 12 and 14). The-pplication of these melthodologiles 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 Limit 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. Powiu Oopendent MCPR For operation less than 38.5% core thermal power, the OLMCPR as a function of core thermal power Is shown in Tables 4-8 and 4-9. 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 4-7 by the applicable MCPR muLtiler given In Tables 448 and 49. For operation at exactly 38.5% core thermal power, MCPR(P) Is the highlr of either of the two methods evaluaaed at 38.5% core thermal power.4.1,2. FIow-Oependont McWf Table 4-10 gives the MCPR(F) limit as a functio of the flow basd on the applicable plant condition.

COLR Dresden 2 Revision 12 Page 30 of 45 4.3. Scram Tim.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 am 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 lmits 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 Interpolation between these values is not supported by Westinghoose mehodology.

In toe event 1hat the ISS t*ms are exceeded, MCPR lmits for the TSSS apply.Tiba 4-1 Soma Times (Rdsersnou 5 d 13)Control Rod humlmn Frton IM (soonds) S (seonds) NSS (meconds)5 0.48 0.360 6324 20 0.89 0.720 0.700 50 1.98 1.580 1.5104 90 3.44 2.740 2.635 4.4.

Unear Heat Generation Ras The thermal mechanical operating limit (TMOL) at rated conditions is established In terms of the maximum LHOR given in Table 5-1 and Table 5-2 as a function of rod nodal (pellet) exposure.The Table 5-1 limits apply to fresh Optlma2 bundle designs for the Cycle 21 and Cycle 22 reloads while the Table 5-2 limits apply to fresh Optima2 bundle designs for the Cycle 23 reload. The limits changed for the Cycle 23 fresh fuel due to the Increase In Uranium enrichment In the Gadolinla rods, which meant that It was no longer guaranteed that all Gadolinla rods would stay below their TMOL limit through monitoring of only the Uranium rods. Therefore, the TMOL of the Gadolinla rods must be monitored explichly for Cycle 23 fresh fuel. The natural Uranium lattices 81 and 89 are still monitored with the original UWi rod limits since they are not enriched (Reference 21).The linear heat generation rate (LHGR) limit is the product of fth exposure dependent LHGR limit from either Table 5-1 or Table 5-2 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 6-3, as applicable.

COLR Dresden 2 Revision 12 Page 42 of 46 2. 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 29.7% 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 TBV Is met. If the opening profile Is NOT met, or if the TBV system cannot pass an equivalent of 29.7% of vessel rated steam flow, utilize the TBVOOS conditon.3. For both Base and EOOS DLOISLO conditions, for operation at NFWT, the OLMCPR limit Is applicable to a variation of +1 0°F1-30*F in feedwater temperature, and an operating steam dome pressure region bounded by the maximum value of 1020 psla and the minimum pressure curve in Reference
8. For operation outslde of NFWT, RFWT of up to 120OF Is also supported for cycle operation through EOC subject to the restriction in Reference 4 for feedwater temperature reductions of greater than 100 WF. The restriction is to maintain less than 100% rod ine. This includes, but is not limited to FWHOOS and FFTR. For a feedwater temperature reduction of between 300F and 120 0 F, fth RFWT limits should be applied.4. For all cases, equivalent of 2 of the first 3.5 Turbine Bypass Valves must be capable of opening via the pressure control system while Turbine Bypass Valves #5-9 ae allowed to be out of service. For aN cases except TBVOOS, the equivalent of 8 of 9 Tu*ie Bypass Valves (as stated in Note 2 above) are required to trip open on Turbine Control Valve fast closure or on Turbine Stop Valve closure. The TBVOOS condition assumes that all of the Turbine Bypass Valves do not trip open on Turbine Control Valve fast closure or on Turbine Stop Valve closure.5.
