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 108.5 Mlb/hr. Operation up to 105% rated flow is licensed for this cycle.Licensed rated thermal power is 3489 MWth.For thermal limit monitoring above 100% rated power or 100% rated core flow, the 100% rated power and the 100% core flow values, respectively, can 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.Core Exposure Definitions (Reference 3): Exposure Nomenclature Core Average Exposure (MWD/MTU)NEOC12 32933 EOC12 35180 Maximum Core Exposure 39180 LaSalle Unit 1 Cycle 12 COLR LaSalle 1 Revision 5 Page 8 1 4. 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 is given in Tables 4-1 and 4-2. During single loop operation, these limits are multiplied by the SLO multiplier listed in Table 4-3.Table 4-1 MAPLHGR for bundle(s):

Operating Limit Minimum Critical Power Ratio 5.1. 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.5.1.1. Power-Dependent MCPR The power-dependent MCPR limit, MCPR(P), is determined from Tables 5-1 through 5-12, and is dependent on exposure, fuel type, and scram speed, in addition to power level. Tables 5-1, 5-2, 5-5, 5-6, 5-9 and 5-10 are applicable to ATRIUM-10 fuel and Tables 5-3, 5-4, 5-7, 5-8, 5-11 and 5-12 are applicable to GEl 4 fuel.5.1.2. Flow -Dependent MCPR Tables 5-13 and 5-14 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.5.2. Automatic Flow Control MCPR Limits Automatic Flow Control MCPR Limits are not provided.5.3. Scram Time NSS and TSSS refer to scram speeds.To utilize the MCPR limits for Technical Specification Scram Speed (TSSS), the scram speed insertion time must be equal to or less than the values provided below.To utilize the MCPR limits for Nominal Scram Speed (NSS), the scram speed insertion time must be equal to or less than the values provided below (Reference 4).Notch Position TSSS Time (sec.)

Recirculation Flow Control Valve Settings Cycle 12 was analyzed with a maximum core flow runout of 105%; therefore the recirculation pump flow control valve must be set to maintain core flow less than 105%(113.9 Mlb/hr) for all runout events (Reference 4). This value is consistent with the analyses of Reference 3.LaSalle Unit 1 Cycle 12 COLR LaSalle 1 Revision 5 Page 10 1 Table 5-1 MCPR(P) for ATRIUM-10 Fuel BOC to NEOC Nominal Scram Speed (NSS)(Reference 3)Core Thermal Power (% of rated)EOOS Combination 0 25 60 80 80(80.1) 100 MCPRp Base Case 2.12 2.12 1.53 , , 1.42 Base Case SLO 2.13 2.13 154 1.43 FHOOS 2.25 2.25 1.57 .43 FHOOS SLO 2.26 2.26 1.58 1.44 TBVOOS 2.15 2.15 1.45 TBVOOS SLO 2.16 2.16 1.62 1.46 One TBVOOS 2.12 2.12 1.54 1.42 One TBVOOS SLO 2.13 2.13 .55 .1.4 PROOS 2.30 2.30 .'M ; -1 PROOS SLO 2.31 2.31 ;A F 1.64 1.49 1.43 PLUOOS 2.12 2.12 1.53 , 1.42 PLUOOS SLO 2.13 2.13 1.54 M0 A 1.43 Combined EOOS 2.30 2.30 1.69 1.46 Combined EOOS SLO 2.31 2.31 X170 1.55 1.47 LaSalle Unit 1 Cycle 12 COLR LaSalle 1 Revision 5 Page 11 1 Table 5-2 MCPR(P) for ATRIUM-10 Fuel BOC to NEOC Technical Specification Scram Speed (TSSS)(Reference 3)Core Thermal Power (% of rated)EOOS Combination 0 25 60 80 80(80.1) 100 MCPRp Base Case 2.17 2.17 1.54 'IS 1.46 Base Case SLO 2.18' 2.18 1.55 ;AW , A 1.47 FHOOS 2.31 2.31 1.59 1.46 FHOOS SLO 2.32 2.32 1.60 .47 TBVOOS 2.23 2.23 1.62 1.48 TBVOOS SLO 24 1.49 One TBVOOS 2.18 2.18 1.56 .22 1.46 One TBVOOS SLO 2.19 2.19 1.57 1.47 PROOS 2.31 2.31 z 1.64 1.50 1.46 PROOS SLO 2.32 2.32 -1.65 1.51 1.47 PLUOOS 2.17 2.17 1.54 1.46 PLUOOS SLO 2.18 2.18 1.55 1.47 Combined EOOS 2.31 2.31 1.69 1.561.4 Cmid,,LO32.

The LHGRFAC(P) is determined from Tables 6-8 through 6-15. The LHGRFAC(F) is determined from Table 6-16 through 6-21.Table 6-1: LHGR Limit for GE1 4-PI OCNAB421-18GZ-1 20T-1 50-T6-2673 (Reference 9)Lattices 6095, 6096, 6097, and 6100 LHGR Limit kW/ft U02 Pellet Burnup LHGR Limit (GWd/MTU) (kW/ft)0.0 13.4 16.0 13.4 63.5 8.0 70.0 5.0 Table 6-2: LHGR Limit for GE14-P1OCNAB422-19GZ-120T-150-T6-2677 (Reference 9)Lattices 6095, 6118, 6119, and 6122 LHGR Limit kWlft U02 Pellet Burnup LHGR Limit (GWd/MTU) (kW/ft)0.0 13.4 16.0 13.4 63.5 8.0 70.0 5.0 LaSalle Unit 1 Cycle 12 COLR LaSalle 1 Revision 5 Page 24 1 Table 6-3: LHGR Limit for GE14-P1OCNAB421-18GZ-120T-150-T6-2673 Lattice 6098 (Reference 9)Lattice 6098 LHGR Limit kWlft U02 Pellet Burnup LHGR Limit (GWd/MTU) (kW/ft)0.0000 13.4000 15.5218 13.4000 16.8142 13.3074 17.5176 13.2275 18.7876 13.0831 20.0443 12.9402 22.5182 12.659 26.1598 12.245 32.1441 11.5647 38.0565 10.8925 43.8915 10.2292 49.6458 9.5177 55.3237 8.7773 60.9382 8.1186 66.5101 6.6107 70.0000 5.0000 LaSalle Unit 1 Cycle 12 COLR LaSalle 1 Revision 5 Page 25 1 Table 6-4: LHGR Limit for GEl 4-P1 OCNAB421-18GZ-1 20T-1 50-T6-2673 Lattice 6099 (Reference 9)Lattice 6099 LHGR Limit kWtft U02 Pellet Burnup LHGR Limit (GWd/MTU) (kW/ft)0.0000 13.4000 15.0262 13.4000 16.3231 13.3633 17.6075 13.2172 18.8785 13.0728 20.1351 12.9299 22.6064 12.6490 26.2427 12.2356 32.2182 11.5562 38.1199 10.8609 43.9416 10.1559 49.6801 9.4886 55.3399 8.7823 60.9347 8.1259 66.4861 6.6218 70.0000 5.0000 LaSalle Unit 1 Cycle 12 COLR LaSalle 1 Revision 5 Page 26 1 Table 6-5: LHGR Limit for GEl 4-P1OCNAB422-19GZ-120T-150-T6-2677 Lattice 6120 (Reference 9)Lattice 6120 LHGR Limit kW/ft U02 Pellet Burnup LHGR Limit (GWd/MTU) (kW/ft)0.0000 13.4000 15.6543 13.4000 16.9580 13.2911 17.6320 13.2145 18.9097 13.0692 20.1735 12.9255 22.6582 12.6431 26.3052 12.2285 32.2788 11.5494 38.1764 10.8789 43.9971 10.2172 49.7379 9.5062 55.4034 8.7676 61.0066 8.1105 66.5684 6.5838 70.0000 5.0000 LaSalle Unit 1 Cycle 12 COLR LaSalle 1 Revision 5 Page 27 1 Table 6-6: LHGR Limit for GEl 4-P1 OCNAB422-1 9GZ-1 20T-1 50-T6-2677 Lattice 6121 (Reference 9)Lattice 6121 LHGR Limit kWlft U02 Pellet Burnup LHGR Limit (GWd/MTU) (kw__ _)0.0000 13.4000 15.1319 13.4000 16.4377 13.3502 17.7308 13.2032 19.0101 13.0578 20.2742 12.9141 22.7569 12.6318 26.3988 12.2178 32.3629 11.5398 38.2490 10.8484 44.0557 10.1457 49.7801 9.4804 55.4267 8.7718 61.0096 8.1170 66.5504 6.5921 70.0000 5.0000 LaSalle Unit 1 Cycle 12 COLR LaSalle 1 Revision 5 Page 28 1 Table 6-7: LHGR Limit for FANP ATRIUM-10 Fuel Al 0-4039B-1 5GV75-1 OOM Al 0-4037B-1 6GV75-1 OOM Al 0-4046B-1 3GV80 A10-3537B-12GV80 Al 0-3537B-1 2GV80a (Reference 3)Pellet Exposure LHGR Limit_ GWd/MTU) (kW/ft)0.00 13.40 17.70 13.40 61.10 9.10 70.40 T -7.30 LaSalle Unit 1 Cycle 12 COLR LaSalle 1 Revision 5 Page 29 1 Table 6-8 LHGRFAC(P) for ATRIUM10 Fuel BOC to NEOC Nominal Scram Speed (NSS)(Reference 3)Core Thermal Power (% of rated)EOOS Combination 02 60 8S 80(80.1) lo5 LHGRFACp Multiplier Base Case 0.73 0.73 1.00 ,0 1.00 Base Case SLO 0.73 0.73 1.00. 1.00 FHOOS 0.68 0.68 0.93 M 1.00 FHOOS SLO 0.68 0.68 0.93 q, ..... ....". 1.00 TBVOOS 0.72 0.72 0.93 ' !y. 1.00 TBVOOS SLO 0.72 0.72 0.93 1.-0 One TBVOOS 0.73 0.73 0.96 ....... 1.00 One TBVOOS SLO 0.73 0.73 0.96 ., 1.00 PROOS 0.65 0.65 , 0.90 1.00 1.00 PROOS SLO 0.65 0.65 0.90 1.00 1.00 PLUOOS 0.73 0.73 1.00 1.0o PLUOOS SLO 0.73 0.73 1.00 7,100 Combined EOOS 0.65 0.65 ,' , 0.87 0.93 0.97 Combined EOOS SLO 0.65 0.65 , 0.87 0.93 0.97 LaSalle Unit 1 Cycle 12 COLR LaSalle 1 Revision 5 Page 30 1 Table 6-9 LHGRFAC(P) for ATRIUM10 Fuel BOC to NEOC Technical Specification Scram Speed (TSSS)(Reference 3)Core Thermal Power (% of rated)EOOS Combination 25 60 80 80(80.1) 100 LHGRFACp Multiplier Base Case 0.71 0.71 1.00 V., 1.00 Base Case SLO 0.71 0.71 1.00 -, 1.00 FHOOS 0.67 0.67 0.92 R r"_ 1.00 FHOOS SLO 0.67 0.67 0.92 1.00 TBVOOS 0.70 0.70 0.91 R 1.00 TBVOOS SLO 0.70 0.70 0.91 1.00 One TBVOOS 0.71 0.71 095 1.One TBVOOS SLO 0.71 0.71 0.95 1.00 PROOS 0.65 0.65 0.89 1.00 1.00 PROOS SLO 0.65 0.65 -gj. 0.89 1.00 1.00 PLUOOS 0.71 0.71 1.00 -1.00 PLUOOS SLO 0.71 0.71 1.00 :- .1.00 Combined EOOS 0.65 0.65 .0.87 0.92 0.96 Combined EOOS SLO 0.65 0.65 0.87 0.92 0.96__________________0.92 0.96___ _______ ______LaSalle Unit 1 Cycle 12 COLR LaSalle 1 Revision 5 Page 31 1 Table 6-10 LHGRFAC(P) for ATRIUM10 Fuel NEOC to EOC Nominal Scram Speed (NSS)(Reference 3)Core Thermal Power (% of rated)EOOS Combination 0 25 60 80 80(80.1) 100 LHGRFACp Multiplier Base Case 0.73 0.73 1.00 , .1.00 Base Case SLO 0.73 0.73 1.00 .' 00 FHOOS 0.68 0.68 0.92 --1.00 FHOOS SLO 0.68 0.68 0.92 1.00 TBVOOS 0.72 0.72 0.93 1 1.00 TBVOOS SLO 0.72 0.72 0.93 1.00 One TBVOOS 0.73 0.73 0.96 ,1 &#xfd;00 One TBVOOS SLO 0.73 0.73 0.96 .1 " .1 00 PROOS 0.65 0.65 0.90 1.00 1.00 PROOS SLO 0.65 0.65 0.90 1.00 1.00 PLUOOS 0.73 0.73 1.00 irgn .% 1.00 PLUOOS SLO 0.73 0.73 1.00 , , 1.00 Combined EOOS 0.65 0.65 0.87 0.92 0.95 Combined EOOS SLO 0.65 0.65 ;

Traversing In-Core Probe System 8.1

== Description:==

When the traversing in-core probe (TIP) system (for the required measurement locations) is used for recalibration of the LPRM detectors and monitoring thermal limits, the TIP system shall be operable with the following:
: 1. movable detectors, drives and readout equipment to map the core in the required measurement locations, and 2. indexing equipment to allow all required detectors to be calibrated in a common location.The following applies for use of the SUBTIP methodology:
The total number of failed and bypassed LPRMs does not exceed 50% (Reference 12).With one or more TIP measurement locations inoperable, the TIP data for an inoperable measurement location may be replaced by data obtained from a 3-dimensional BWR core monitoring software system adjusted using the previously calculated uncertainties, provided the following conditions are met: (A) When there is not a prior complete TIP-calibrated data set available:
: 1. To comply with Technical Specification SR 3.3.1.1.8, LPRMs, within their calibration frequency, in locations without a TIP trace are not recalibrated, 2. LPRMs in locations without a TIP trace will not be used by POWERPLEX in any core power distribution calculations, and 3. The total number of out-of-service TIPs does not exceed 42% (18 channels).(B) When there is a prior complete TIP-calibrated data set available:
: 1. All TIP traces have previously been obtained at least once in the current operating cycle when the reactor core was operating above 20% power, (Reference
: 6) and 2. The total number of simulated channels (measurement locations) does not exceed 42% (18 channels).
Otherwise, with the TIP system inoperable, suspend use of the system for the above appficable monitoring or calibration functions.

===8.2 Bases===
The operability of the TIP system with the above specified minimum complement of equipment ensures that the measurements obtained from use of this equipment accurately represent the spatial neutron flux distribution of the reactor core. The normalization of the required detectors is performed internal to the core monitoring software system.Substitute TIP data, if needed, is 3-dimensional BWR core monitoring software calculated data which is adjusted based on axial and radial factors calculated from previous TIP sets. Since the simulation and adjustment process could introduce uncertainty, a maximum of 18 channels may be simulated to ensure that the uncertainties assumed in the substitution process methodology remain valid.LaSalle Unit 1 Cycle 12 COLR LaSalle 1 Revision 5 Page 40 1 9. Stability Protection Setpoints The OPRM PBDA Trip Settings (Reference 3): I Corresponding Maximum PBDA Trip Amplitude Setpoint (Sp) Confirmation Count Setpoint (Np)1.11 14 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.

All limits support PLUOOS < 60% RTP.2 With or without 1 stuck closed TCV or TSV (except for TBVOOS -TBVOOS do not support TCV or TSV stuck closed).Note: The MCPR and LHGR operating limits may be different based on whether 1 TCV or TSV is or is not stuck closed due to MCPR(p) and LHGRFAC()
considerations.
The pressurization MCPR(f) limits and LHGRFAC(f) multipliers should be applied to support operation when any of the following EOOS conditions exist: one stuck closed TCV, or one stuck closed TSV or one MSIVOOS. Note that operation with 1 MSIVOOS is supported as long as core thermal power is maintained 
< 75% of 3489 MWt.LaSalle Unit 1 Cycle 12 COLR LaSalle 1 Revision 5 Page 42 1 Any combination of TCV slow closure, no RPT and/or FHOOS. For FFTR/Coastdown any combination of TCV Slow Closure and/or no RPT (as a reduced feedwater temperature is already assumed as part of the base assumptions for FFTR/Coastdown).
4 FFTR/Coastdown Operation is defined as any cycle exposure beyond full power/flow, all rods out condition with plant power slowly lowering while core flow is held constant.
TBVOOS and one TBVOOS limits for FFTR/Coastdown operation are only valid for Cycle 12 core average exposures greater than 32,933 MWD/MTU. With the OPRM system armed, current analysis supports up to 1 00'F decrease in feedwater temperature.
5 During FFTR/Coastdown portion of the cycle, feedwater heaters are taken out of service to achieve the FFTR.The SLO boundary was not moved up with the incorporation of MELLLA. The power-flow boundary for SLO at power uprated conditions remains the ELLLA boundary for pre-uprate conditions.
The TBVOOS condition assumes that ALL the turbine bypass valves do not trip open on turbine control valve fast closure or on turbine stop valve closure. However, either TBV #1. #2, #3, or #4 must be capable of opening via the pressure control system in this EOOS (see Reference 15).The FHOOS option supports a feedwater temperature reduction of 1 00&deg;F from BOC to 5100 MWD/MTU and 50&deg;F from 5100 MWD/MTU to 6600 MWD/MTU. Upon arming of the OPRM system, the 50&deg;F feedwater temperature reduction exposure dependent ICA restriction is not applicable and the feedwater temperature reduction of 1001F will apply. ICA regions are only applicableup to an exposure of 6600 MWD/MTU. Operation beyond 6600 MWD/MTU supports a 1 00&deg;F feedwater temperature reduction with the OPRM system armed.9 Any combination of TCV slow closure, in combination with one (or more) TBVOOS. Any combination of TCV slow closure, in combination with one TBVOOS and 1 TCV or TSV stuck closed. At core thermal powers of less than or equal to 85% of rated, any combination of 1 TCV or TSV stuck closed, TCV slow closure, and 1TBVOOS (i.e. only 4 TBVs will open on turbine trip and 3 TBVs will open for pressure control, which must consist of any combination of TBV#1, #2, #3 and #4) (see Reference 16).LaSalle Unit 1 Cycle 12 COLR LaSalle 1 Revision 5 Page 43 1 11.
