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.

The Modes of Operation in section 8 and the limits provided for OLMCPR in section 4 and the OPRM stability protection setpoints in section 7 are only valid to a cycle exposure of 10000 MWd/MTU per reference 3 and reference 22 limitations.

Rated core flow is 98 Mlb/hr. Operation up to 108% rated flow is analyzed but not licensed for this cycle. Licensed 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, all rods out condition with plant power slowly lowering to a lesser value while core flow is held constant.

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 either NSS, ISS, or TSSS. Only MCPR limits vary with scram speed.

Westinghouse methods used in slow and fast transient analyses as well as SLMCPR calculations are sufficient to cover the small effect of the 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 3).

4. Operating Limit Minimum Critical Power Ratio The Operating Limit Minimum Critical Power Ratios (OLMCPRs) for D3C22 were established to protect the Safety Limit Minimum Critical Power Ratio (SLMCPR) for the abnormal operational occurrences. The SLMCPR values for DLO and SLO for D3C22 were determined to be 1.12 and 1.14, respectively (Reference 3), which are unchanged from the NRC-approved values for the previous operating cycle (i.e., D3C21) .

In determining the SLMCPR values for D3C22, Westinghouse applied the methodologies from CENPD-300-P-A, consistent with the manner specified in Limitations 1 through 6 and 8 of the NRC Safety Evaluation Report (SER) approving CENPD-300-P-A (References 18.and 19). The application of these methodologies was previously approved by the NRC in license amendment 213 to Renewed Facility Operating License DPR-25 (Reference 17).

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, MCPR(P) is shown in Tables 4-8 and 4-9. For operation at greater than 38.5% core thermal power, MCPR(P) is determined by multiplying the applicable rated condition OLMCPR limit shown in Tables 4-2 through 4-7 by the applicable MCPR multiplier K(P) given in Tables 4-8 and 4-9. For operation at exactly 38.5% core thermal power, MCPR(P) is the higher of either of the two methods evaluated at 38.5% core thermal power.

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.

4.2. Automatic Flow Control MCPR Limits Automatic Flow Control MCPR Limits are not provided.

Dresden Unit 3 Cycle 22

COLR Dresden 3 Revision 6 Page 36 of 54 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 for each of the scram speeds as a function of control rod insertion fraction 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 any of the .NSS 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 any of the ISS times are exceeded, MCPR limits for the TSSS apply.

Recirculation Pump Motor Generator Settings Cycle 22 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 12). This value is consistent with the analyses of Reference 3.

5. Linear Heat Generation Rate The thermal mechanical operating limit at rated conditions is established in terms of the maximum LHGR given in Table 5-1 as a function of rod nodal (pellet) exposure. 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 Table 5-1 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 5-2.

The LHGRFAC(F) is determined from Table 5-3.

1[ Corresponding Maximum PBDA Trip Amplitude Setpoint (Sp) Confirmation Count Setpoint (Np) 11.15 16 The OPRM PBDA trip settings are valid to a cycle exposure of 10000 MWd/MTU per Reference 3. limitations.

The PBDA is the only OPRM setting credited in the safety analysis as documented in the licensing basis for the OPRM system.

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.

Common Notes -Applicable to Base Case and all EOOS Combinations

1. All. modes are allowed for full power operation at MELLLA up to a cycle exposure of, 10000 MWD/MTU subject to the restrictions in Tables 8-1 and 8-2. Each EOOS Option may be combined with each of the following conditions provided the requirements of References 20 and 21 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 0 F/-30 0 F temperature band around the nominal FWT and operating steam dome pressure region bounded by the maximum value of 1020 psia and the minimum pressure curve from Reference 15, while the FWTR results are valid. for the minimum FWT curve from Reference 15. For operation outside of NFWT, RFWT from 30 OF to 120°F is also supported for cycle operation through 10000 MWd/MTU cycle energy subject to the restriction in Reference 14-for feedwater temperature reductions of greater than 100 0F. The restriction is to maintain less than 100% rod line. This includes, but is not limited to FWHOOS and FFTR. For a feedwater temperature reduction of between 30'F and 120'F, the RFWT limits should be applied.
3. All analyses support the fastest Turbine Bypass Valve (assumed to be #1) OOS, with the remaining 8 Turbine Bypass Valves. meeting the assumed opening profile in Reference
11. The analyses also support Turbine Bypass flow of 29.8% of vessel rated steam flow,ý equivalent to one TBV OOS (or partially closed TBVs equivalent to one closed TBV), if the assumed opening profile for the remaining Turbine Bypass Valves 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. (Reference 3)
4. For all cases including TBVOOS, equivalent of 2 of the first 3.6 TBVs must be capable of opening via the pressure control system while TBVs #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 Turbine Bypass Valves do nopt trip open on TCV fast closure or on TSV closure. (Reference 3)
5. A single MSIV may be. taken OOS (shut) under all EOOS Options, as long as core, thermal power is maintained<* 75% of 2957 MWth (Reference 3).
