Subject:

Unit 2 Cycle 12 Core Operating Limits Report (COLR)

The purpose of this letter is to advise you of the Exelon Generation Company, LLC (EGC) review and approval of the LaSalle Unit 2 Cycle 12 reload under the provisions of 10 CFR 50.59, "Changes, tests and experiments," and to transmit the Core Operating Limits Report (COLR) for Cycle 12, consistent with Generic Letter 88-16, "Removal of Cycle-Specific Parameter Limits From Technical Specifications." This report is being submitted in accordance with LaSalle County Station Technical Specification 5.6.5, "Core Operating Limits (COLR)," item d.

The reload licensing analyses performed for Cycle 12 utilized NRC approved methodologies.

The Unit 2 Cycle 12 core, which consists of NRC approved fuel designs developed by Global Nuclear Fuel (GNF) and Framatome Advanced Nuclear Fuel, Inc. (i.e., Framatome), was designed to operate within approved fuel design criteria provided in the Technical Specifications and related Bases. The core operating characteristics are bounded by the Updated Final Safety Analysis Report (UFSAR) allowable limits.

EGC has performed a review of the relevant reload licensing documents, associated Bases, and references in accordance with 10 CFR 50.59. The review process concluded that the reload does not require NRC review and approval.

Should you have any questions concerning this submittal, please contact Mr. Terrence W.

Simpkin, Regulatory Assurance Manager, at (815) 415-2800.

Respectfully, j.4---

3. 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.

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.

5. 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 GE14 fuel.

5.1.2. Flow - Dependent MCPR Tables 5-13 and 5-14 give the MCPR(F) limit as a function of the core 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).

(117.18 Mlb/hr) for all runout events (Reference 4). This value is consistent with the analyses of Reference 3.

ROD BLOCK MONITOR UPSCALE TRIP FUNCTION ALLOWABLE VALUE Two Recirculation Loop 0.66 Wd + 54.0%

Operation 0.66_Wd_+_54.0%

Single Recirculation Loop 0.66 Wd + 48.7%

Operation 0.66IW__+__8.7%

The setpoint may be lower/higher and will still comply with the rod withdrawal error (RWE) analysis because RWE is analyzed unblocked. The allowable value is clamped with a maximum value not to exceed the allowable value for a recirculation loop drive flow (Wd) of 100%.

Wd - percent of recirculation loop drive flow required to produce a rated core flow of 108.5 Mlb/hr.

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 10).

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 applicable 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.

9. Stability Protection Setpoints The OPRM PBDA Trip Settings (Reference 3):

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.

10. Modes of Operation The allowed modes of operation with combinations of equipment out-of-service are as described below:

Equipment Out of Service FFTRJ Options ei 2

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(f) and LHGRFAC(f) 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 2 Cycle 12

COLR LaSalle 2 Revision 2 Page 40 3 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 31,988 MWD/MTU. The 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.

6 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 the turbine bypass valves do not trip open on turbine control valve fast closure or on turbine stop valve closure. However, operation of the turbine bypass valves via the pressure control system is credited, i.e. all bypass valves must be capable of opening in this EOOS.

The FHOOS option supports a feedwater temperature reduction of 1 00°F.

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. TCV slow closure in combination with more than one TBVOOS and 1 TCV or TSV stuck closed is not supported per Note 2.

'0 The one TBVOOS condition assumes that one turbine bypass valve does not trip open on turbine control valve fast closure or on turbine stop valve closure. Operation of one turbine bypass valve via the pressure control system is not credited, i.e. this EOOS assumes the one bypass valve is not capable of opening.
