Unit 2 Cycle 10 Core Operating Limits Report (COLR)

Exelon Generation Company (EGC), LLC, in accordance with LaSalle County Station Technical Specifications (TS) Section 5.6.5, "Core Operating Limits Report,"

is submitting a revision to the Core Operating Limits Report (COLR). The revision is due to the implementation of new operating limits in the LaSalle Unit 2 Cycle 10 core beyond the first sequence exchange. The control blade history effects on fresh fuel are incorporated in the minimum critical power ratio (MCPR) operating limits and power-dependent limiting heat generation rate (LHGR) limit penalties. The penalties are applied to specific core locations to ensure that control blade history effects on fresh fuel assemblies are properly accounted for in the calculation of maximum nodal LHGR and MCPR.

Additionally, associated administrative changes have also been incorporated.

Should you have any questions concerning this submittal, please contact Mr. Glen Kaegi, Regulatory Assurance Manager, at (815) 415-2800.

Respectfully,

/C/

1. Average Planar Linear Heat Generation Rate (3.2.1) 1.1 Technical Specification

Reference:

Section 3.2.1.

1.2

Description:

Tables 1-1 and 1-2 are used to determine the maximum average planar linear heat generation rate (MAPLHGR) limit for each fuel type. Limits given in Tables 1-1 and 1-2 are for Dual Reactor Recirculation Loop Operation.

For Single Reactor Recirculation Loop Operation (SLO), the MAPLHGR limits given in Tables 1-1 and 1-2 must be multiplied by a SLO MAPLHGR multiplier. The SLO MAPLHGR multiplier for ATRIUM-10 and ATRIUM-9B fuel is 0.90 (Reference 3 Section 7.2.1).

2. Minimum Critical Power Ratio (3.2.2) 2.1 Technical Specification

Reference:

Section 3.2.2.

2.2

Description:

MCPR limits from BOC to End of Full Power are applicable up to a core average exposure of 30,317.0 MWd/MTU (which is the full power licensing basis exposure used by FANP).

(Reference 3 Section 4.2.1). Limits beyond the EOC exposure are not provided.

2.2.1 Manual Flow Control MCPR Limits The Operating Limit MCPR (OLMCPR) is determined from either section 2.2.1.1 or 2.2.1.2, whichever is greater at any given power and flow condition.

2.2.1.1 Power-Dependent MCPR The power-dependent MCPR value, MCPRp, is determined from Tables 2-1 through 2-16, and is dependent on fuel type and scram speed, in addition to power level. Tables 2-1 through 2-6 and Tables 2-9 through 2-14 are applicable to ATRIUM-10 fuel. Tables 2-7, 2-8, 2-15 and 2-16 are applicable to ATRIUM-9B fuel.

2.2.1.2 Flow-Dependent MCPR The flow dependent MCPR value, MCPRF, is determined from Table 2-17 for all fuel types in Cycle 10.

2.2.2 Automatic Flow Control MCPR Limits Automatic Flow Control is not supported for L2CIO.

2.2.3 Nominal Scram Speeds To utilize the MCPR limits for Nominal Scram Speeds (NSS), the core average scram speed insertion time must be equal to or less than the following values (Reference 8 Section 7.7).

Description:

The LHGR Limit is the product of the LHGR Limit from Tables 3-1a, 3-lb, 3-1c or 3-2 and the minimum of either the power dependent LHGR Factor, LHGRFACp, or the flow dependent LHGR Factor, LHGRFACF. The applicable power dependent LHGR Factor (LHGRFACp) is*

determined from Table 3-3, 3-4, 3-7 or 3-8 for ATRIUM-10 fuel or Table 3-5, 3-6, 3-9 or 3-10 for ATRIUM-9B fuel. The applicable flow dependent LHGR Factor (LHGRFACF) is determined from Table 3-11 for all fuel types.

5. Traversing In-Core Probe System (3.2.1, 3.2.2, 3.2.3) 5.1 Technical Specification

Reference:

Technical Specification Sections 3.2.1, 3.2.2, 3.2.3 for thermal limits require the TIP system for recalibration of the LPRM detectors and monitoring thermal limits.

5.2

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:

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:

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, (References 5, 6 and
7) 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.

5.3 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.

2 All EOOS options support I TCV stuck closed except EOOS Case 1 TBVOOS. A separate equipment out-of-service analysis was provided for the combination of TBVOOS and 1 TCV stuck closed.

3 Coastdown limits are not provided. Coastdown limits will not be required based on current burnup projections. However, thermal limits for coastdown are provided in Reference 3. Feedwater heaters OOS (FHOOS) may be intentionally entered to maintain core thermal power provided the end of cycle exposure corresponding to a core average exposure of 30,317.0 MWd/MTU is not exceeded.

4 Three sets of thermal limits are provided. The first set of thermal limits, from 1 through 20, are provided for use from the beginning of cycle until the first sequence exchange (from A2 to Al) at approximately 4,970 +/-

200 MWd/MT. The second set of thermal limits, from 21 through 40, are provided for use from the first sequence exchange (from A2 to Al) at approximately 4,970 MWd/MT until 16,116 MWd/MT (defined as the middle of cycle (MOC) licensing basis. The third set of thermal limits, from 41 through 60, are applicable from 16,116 MWd/MT defined as the middle of cycle licensing basis to the licensing basis end of cycle burnup corresponding to a core average exposure of 30,317 MWd/MTU. Note that the thermal limit sets 41-60 can be implemented at exposures between 14,290 and 16,116 MWd/MT.

5 Feedwater heaters OOS (FHOOS) supports a reduction of up to 100 0F in feedwater temperature. FHOOS may be an intentionally entered mode of operation or an actual OOS condition. Feedwater heaters OOS (FHOOS) may be intentionally entered to maintain core thermal provided the end of cycle exposure corresponding to a core average exposure of 30,317 MWd/MTU is not exceeded.

Technical Requirements Manual - Appendix J L2C10 Core Operating Limits Report 6 The SLO boundary was not moved up with the incorporation of MELLLA and power uprate. The 100% rod line (FCL) bounds this value.

"ICF is analyzed up to 105% rated core flow.

8 If operating with FHOOS (alone or in combination with other EOOS), operation in the MELLLA region is supported by current transient analyses (UFSAR Chapter 15), but is administratively limited to less than 100% rod line (FCL) due to thermal-hydraulic stability concerns.

s The Standard Power-Flow Region is that part of the Power-Flow map region below 100% rod line (FCL) up to 100% core flow.

° A single MSIV may be taken OOS (shut) under any and all OOS options as long as core thermal power is maintained < 75% of 3489 MWt (Reference 10).

" A TSV may be taken OOS (shut) and is bounded by operation with I TCV stuck closed (Reference 11).

12 For temporary operation with a pressure regulator out of service (PROOS), the TCV slow closure limits should be applied (Reference 13).
