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 thiscycle, however, flow cannot exceed 103.4% rated flow due to unit specific limitations.

Ucensedrated 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 rodsout 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 withscram speed.For thermal limit monitoring above 100% rated power or 100% rated core flow, the 100% ratedpower 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 ofoperation as supported by the reload analysis.

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

COLR Dresden 2 Revision 12Page 8 of 453. Average Planar Linear Neat Generation RateFor natural uranium lattices, DLO and SLO MAPLHGR values are provided in Table 3-1. For allother 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 theupdated limits provided In Reference 11, which supersede the limits provided In the odginal RLRdocumented In Reference 3.TaWie 3-1 MAPLHGR for uNid~stamw.

Operating Limit Minimum Critical Power RatioThe Operating Limit Minimum Critical Power Ratios (OLMCPRe) for 02C23 were established toprotect 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 and1.14 (Reference 13), respectively, which are unchanged from the NRC-approved values for theprevious operating cycle (I.e., 02C22).In determining the SLMCPR values for D2C23, Westinghouse appled the methodologies fromCENPD-300-P.A, consistent with the manner specified in Limitations I through 6 and 8 of theNRC 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 LimitThe OLMCPR is determined for a given power and flow condition by evaluating thepower-dependent MCPR and the flow-dependent MCPR and selecting the greater of thetwo.4,1.1. Powiu Oopendent MCPRFor operation less than 38.5% core thermal power, the OLMCPR as a function ofcore thermal power Is shown in Tables 4-8 and 4-9. For operation at greaterthan 38.5% core thermal power, the OLMCPR as a function of core thermalpower is determined by multiplying the applicable rated condition OLMCPR limitshown In Tables 4-2 through 4-7 by the applicable MCPR muLtiler given InTables 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% corethermal power.4.1,2. FIow-Oependont McWfTable 4-10 gives the MCPR(F) limit as a functio of the flow basd on theapplicable plant condition.

COLR Dresden 2 Revision 12Page 30 of 454.3. Scram Tim.TSSS, ISS, and NSS refer to scram speeds. TSSS Is the Technical Specification ScramSpeed, 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 timesurveillance measurements.

In the event that plant surveillance shows these scramInsertion times to be exceeded, the MCPR lmits are to default to the values whichcorrespond to the ISS scram time. The ISS times have been chosen to provide anIntermediate value between the NSS and TSSS, but Interpolation between these valuesis not supported by Westinghoose mehodology.

In toe event 1hat the ISS t*ms areexceeded, MCPR lmits for the TSSS apply.Tiba 4-1 Soma Times(Rdsersnou 5 d 13)Control Rodhumlmn Frton IM (soonds)

Unear Heat Generation RasThe thermal mechanical operating limit (TMOL) at rated conditions is established In terms of themaximum 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 reloadswhile the Table 5-2 limits apply to fresh Optima2 bundle designs for the Cycle 23 reload. Thelimits changed for the Cycle 23 fresh fuel due to the Increase In Uranium enrichment In theGadolinla rods, which meant that It was no longer guaranteed that all Gadolinla rods would staybelow their TMOL limit through monitoring of only the Uranium rods. Therefore, the TMOL of theGadolinla rods must be monitored explichly for Cycle 23 fresh fuel. The natural Uranium lattices81 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 limitfrom 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, asapplicable.

COLR Dresden 2 Revision 12Page 42 of 462. All analyses support the fastest Turbine Bypass Valve (assumed to be #1) OOS, with theremaining 8 TBVs meeting the assumed opening profile In Reference

7. The analyses alsosupport Turbine Bypass flow of 29.7% of vessel rated steam flow, equivalent to one TBVOOS (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 TBVsystem cannot pass an equivalent of 29.7% of vessel rated steam flow, utilize the TBVOOSconditon.

3. For both Base and EOOS DLOISLO conditions, for operation at NFWT, the OLMCPR limit Isapplicable to a variation of +1 0°F1-30*F in feedwater temperature, and an operating steamdome pressure region bounded by the maximum value of 1020 psla and the minimumpressure curve in Reference

8. For operation outslde of NFWT, RFWT of up to 120OF Is alsosupported for cycle operation through EOC subject to the restriction in Reference 4 forfeedwater temperature reductions of greater than 100 WF. The restriction is to maintain lessthan 100% rod ine. This includes, but is not limited to FWHOOS and FFTR. For a feedwater temperature reduction of between 300F and 1200F, fth RFWT limits should be applied.4. For all cases, equivalent of 2 of the first 3.5 Turbine Bypass Valves must be capable ofopening via the pressure control system while Turbine Bypass Valves #5-9 ae allowed to beout 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 oron Turbine Stop Valve closure.

The TBVOOS condition assumes that all of the TurbineBypass Valves do not trip open on Turbine Control Valve fast closure or on Turbine StopValve closure.5.
