Exelon Nuclear - Nuclear Fuels DOC ID: COLR Clinton 1 Rev.14 CL 1C19 Core Operating Limits Report 2.0 General Information This report is prepared in accordance with Technical Specification 5.6.5 of Reference 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 NRC-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 (ICF) up to 107% of rated core flow
  • Final Feedwater Temperature Reduction (FFWTR) up to 50°F during cycle extension operation
  • 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 defi.ned in Section 1 and Section 9.

Reference:

  • sections 3.2.1 and 3.4.1.

3.2

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 (a change in temperature greater than 10 °F, but less than or equal to 50 °F FWTR), the MAPLHGR limits given in Table 3-1 must be multiplied by a MAPLHGR multiplier provided in Table 3-3. This multiplier accounts for potential feedwater riser flow asymmetries (Reference 7).

Reference:

Sections 3.2.2, 3.4.1, and 3.7.6.

4.2

Description:

The Operating Limit MCPR (OLMCPR) is determined from either Section 4.2.1 or 4.2.2, whichever is greater at any given power and flow condition.

4.2.1 Power-Dependent MCPR For operation less than or equal to 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 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.

4.2.2 Flow-Dependent MCPR Tables 4-4 through 4~7 give the MCPR(F) as a function of flow 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.

4.2.3 Option A and Option B Option A and Option B refer to use of scram speeds for establishing MCPR operating limits.

Option A scram speed is the BWR/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.

4.2.4 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 less than 109% (92.105 Mlb/hr) for all runout events (Reference 3).

Exelon Nuclear - Nuclear Fuels DOC ID: COLR Clinton 1 Rev. 14 CL1C19 Core Operating Limits Report 5.0 Linear Heat Generation Rate Limits 5.1 Technical Specification

Reference:

Section 3.2.3, 3.4.1, and 3.7.6.

5.2

Description:

The lfnear heat generation rate (LHGR) limit 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 Multiplier, LHGRFAC(P), the flow dependent LHGR Multiplier, LHGRFAC(F), or the single loop operation (SLO) Multiplier if applicable. The SLO multiplier can be found in Table 5-3. The LHGRFAC(P) is determined from Table 5-4 and 5-5. The LHGRFAC(F) is determined from Tables 5-6 and 5-7, depending on plant conditions. Tables 5-1 and 5-2 are the LHGR limit as a function of peak pellet exposure.

For Loss of 'FULL' Feedwater Heating (a change in temperature greater than 10 °F, but less than or equal to 50 °F FWTR), LHGRFAC(P) is determined from Table 5-8 and 5-9, LHGRFAC(F) is determined from Tables 5-10 and 5-11, depending on plant conditions. Concurrent operation with SLO and reduced feedwater heating has not been evaluated and thus is not a valid operating mode.

The OPRM Period Based Detection Algorithm (PBDA) Trip Setpoint for the OPRM System for use in Technical Specification 3.3.1.3 is found in Table 8-1. This value is based on the cycle specific analysis documented in Reference 3.

Stability-based OLMCPR is non-limiting for the PBDA setpoint in Table 8-1.

Exelon Nuclear - Nuclear Fuels DOC ID: COLR Clinton 1 Rev. 14 CL1C19 Core Operating Limits Report 9.0 Modes of Operation The Allowed Modes of Operation with combinations of Equipment Out-of-Service (EOOS) are as described below in Table 9-1:

  • Table 9-1 Modes of Operation (Reference 3)

Operating Region 1 2 EOOS Options Standard MELLLA ICF FFWTR Coastdown 3

Base Case DL0 .4 Yes Yes Yes Yes Yes 23 Base Case SL0

  • Yes No No No Yes PROOS/PLUOOS DL0 3 .4, 5 Yes Yes Yes Yes Yes 235 PROOS/PLUOOS SL0 *
  • Yes No No No Yes 6

Two or More TBVOOS DL0 4

  • Yes Yes Yes Yes Yes 26 Two or More TBVOOS SL0
  • Yes No No No Yes Notes:
1. A single Main Steam Isolation Valve (MSIV) *out of service is supported at or below 75% power. (Reference 3)
2. Concurrent operation with SLO and Loss of 'FULL' Feedwater Heating (a change in temperature greater than 1O °F, but less than or equal to 50 °F FWTR), MELLLA, ICF, or FFWTR has not been evaluated and thus is not a valid operating mode .. (Reference 8)
3. Includes 2 SRVOOS, 1 TCV stuck closed, 1 TSV stuck closed, 1 TBVOOS, and up to a 50°F feedwater temperature reduction (FWTR includes feedwater heater OOS or final feedwater temperature reduction) at any point in cycle operation in Dual Loop mode. (Reference 12)
4. For operation with Loss of 'FULL' Feedwater Heating (a change in temperature greater than 10 °F, but less than or equal to 50 °F FWTR), the MAPLHGR is determined using the multiplier in Table 3-3 and the LHGR value is determined from Tables 5-8, 5-9, 5-10, and 5-11.
5. Concurrent operation with either or both of PROOS + PLUOOS is allowed.
6. Includes 2 SRVOOS and up to a 50°F feedwater temperature reduction (FWTR includes feedwater heater OOS or final feedwater temperature reduction) at any point in cycle operation in Dual Loop mode. (Reference 12)
7. End-of-cycle power coastdown operation down to 40% reactor power is supported by Methodology Reference 1.

Coastdown operation beyond the EOR condition is conservatively bounded by the reload licensing analyses at the EOR condition for a normal coastdown power profile. During coastdown, operation at a power level above that which can be achieved (at all-rods 0 out with all cycle extension features utilized, e.g., ICF, FFWTR) with steady-state equilibrium xenon concentrations is not supported.
