1. Power and flow dependent limits and multipliers are listed for various power and flow levels. Linear interpolation is to be used to find intermediate values. These values have been determined using NRG-approved methodologies presented in Section 10 and are established such that all applicable limits of the plant safety analysis are met The data presented in this report is valid for all licensed operating domains on the operating map. including:

.. Maximum Extended Load Line Limit down to 99% of rated core flow during full power operation " Increased Core Flow (lCF) up to i 07% of rated core flow " Final Feedwater Temperature Reduction (FFWfR) up to 50cF during cycle extension operation c Feedwater Heater Out of Service (FWHOOS) up to 50°F feedwater temperature reduction at any time during the cycle prior to cycle extension.

Equipment out of service conditions are as defined in Section 1 and Section 9. Page 8 of 27 Exelon Nuclear -Nuclear Fuels DOC !D: COLR Clinton i Rev. 11 CL 1C17 Core Operating Limits Report 3.0 MAPLHGR Limits 3.0 Technical Specification

Reference:

Sections 3.2.1 and 3.4.1. 3.1

Description:

Table 3-1 is used to determine the maximum average planar linear heat generation rate (MAPLHGR) limit. Limits listed in Table 3-1 are for dual reactor recirculation loop operation (DLO). For single reactor recirculation loop operation (SLO), the MAPLHGR limits given in Table 3-1 must be multiplied by a SLO MAPLHGR multiplier provided in Table 3-2. For Loss of 'FULL' Feedwater Heating (+/-10 °F outside design NORMAL temperature, meaning changes in feedwater temperature greater than 10 °F and less than or equal to 50 °F), the MAPLHGR limits given in Table 3-1 must be multiplied by a LHGR multiplier provided in Table 3-3. This multiplier accounts for potential feedwater riser flow asymmetries (Reference 7). Table 3-1 MAPLHGR Versus Average Planar Exposure 1 (Reference

Reference:

Sections 3.2.2, 3.4.1, and 3.7.6. 4.1

Description:

The various MCPR limits are described below. 4.1.1 Manual Flow Control MCPR Limits The Operating Limit MCPR (OLMCPR) is determined from either Section 4.1.1.1 or 4.1.1.2, whichever is greater at any given power and flow condition.

4.1.1.1 Power-Dependent MCPR For operation less than 33.3% core thermal power, the MCPR(P} as a function of core thermal power is determined from Table 4-2 or Table 4-3 depending on plant conditions.

For operation at greater than or equal to 33.3% core thermal power, the OLMCPR as a function of core thermal power is determined by multiplying the applicable rated condition OLMCPR limit shown in Table 4-1 by the applicable MCPR multiplier K(P) given in Table 4-2 or Table 4-3. 4.1.1.2 Flow-Dependent MCPR Tables 4-4 through 4-7 give the MCPR(F) as a function off!ow based on the applicable plant condition.

The limits for dual loop operation are listed in Tables 4-4 and 4-6. The limits for single loop operation are listed in Tables 4-5 and 4-7. The MCPR(F) determined from these tables is the flow dependent OLMCPR. 4.1.2 Automatic Flow Control MCPR Limits Automatic Flow Control MCPR Limits are not provided.

Page 11 of 27 Exe!on Nuclear* Nuclear Fuels CL1C17 Core Operating Limits Report 4.1.3 Potion A and Option B DOC !D: COLR Clinton i Rev. 1'l Opiion A and Option B refer to use of scram speeds for establishing MCPR operating iirnits. Option A scram speed is the BVVR/6 Technical Specification scram speed. The Technical Specification scram speeds must be met to utilize the Option A MCPR limits. Cycle-specific reload analyses performed by GNF for Option A MCPR limits utilized a 20% core average insertion time of 0.516 seconds (Reference 6). To utilize the MCPR limits for the Option B scram speed, the cycle average scram insertion time for 20% insertion must satisfy equation 2 in Reference 5 Section 4. If the cycle average scram insertion time does not meet the Option B criteria, the appropriate MCPR value may be determined from a linear interpolation between the Option A and B limits as specified by equation 4 in Reference 5 Section 4. 4. 1.4 Recirculation Flow Control Valve Settings The cycle was analyzed with a maximum core flow runout of 109%; therefore the recirculation flow control valve must be set to maintain core flow fess than 109% (92.105 Mlb/hr) for all runout events (Reference 3).

Description:

DOC ID: COLR Ciinton i Rev. 11 The linear heat generation rate (LHGR) fimit is the product of the exposure dependent LHGR limit (from Table 5-1 for U02 fuel rods and Table 5-2 for Gadolinia fuel rods) 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 if applicable.

The LHGRFAC(P) is determined from Table 5-3. The LHGRFAC(F) is determined from Tables 5-4 and 5-5, depending on plant conditions.

The SLO multiplication factor can be found in Table 5-6. Tables 5-1 and 5-2 are the LHGR limit as a function of peak pellet exposure.

  • For Loss of 'FULL' Feedwater Heating (+/-1 O °F outside design NORMAL temperature, meaning changes in feedwater temperature greater than 10 °F and less than or equal to 50 °F), LHGRFAC(P) is determined from Table 5-7 and LHGRFAC(F) is determined from Tables 5-8 and 5-9, depending on plant conditions.

Concurrent operation with SLO and reduced feedwater heating has not been evaluated and thus is not a valid operating mode. (Reference
