* Extended Load Line Limit down to the minimum licensed core flow (i.e., 85.0% of rated) during full power operation,
* Extended Load Line Limit down to the minimum licensed core flow (i.e., 85.0% of rated) during full power operation,
* Rated core flow is 67 .5 Mlb/hr,
* Rated core flow is 67 .5 Mlb/hr,
* End-of-cycle coastdown to a minimum power level of 40% of rated power,
* End-of-cycle coastdown to a minimum power level of 40% of rated power,
* Feed water temperature of no more than -I 0°F off nominal is licensed for this cycle. Further information on the cycle-specific analyses for Nine Mile Point Unit I Cycle 22 and the associated operating domains discussed above is available in Reference

For partial loop operation, a fuel-type-dependent multiplier is used, which is shown in Table 3-10. For operation with either four or three recirculation loops in service, multiply the most limiting values shown in Tables 3-1 through 3-3 by the GE 11 value in Table 3-10 and multiply the most limiting values shown in Tables 3-4 through 3-9 by the GNF2 value in Table 3-10. The power and flow dependent multipliers for MAPLHGR have been removed and replaced with LHGRF AC(P) and LHGRF AC(F); therefore, MAPF AC(P) and MAPF AC(F) are equal to 1.0 for all power and flow conditions (Reference 2).

Tables 4-1 and 4-2 are derived from Reference 2 and are valid for all Cycle 22 operating domains. Nine Mile Point Unit 1 Cycle 22 has a mid-cycle MCPR breakpoint, as defined in Table 4-1. An adder, presented in Table 4-2, is required to be applied to all limits in Table 4-1 and MCPR(P) in Table 4-3 in the event of three recirculation loop operation.
 
Table 4-1 and 4-2 limits are bounding for both GEl 1 and GNF2 fuel types. The power dependent MCPR limits are presented in Table 4-3 and are valid for both GEl 1 and GNF2 fuel types (Reference 2). When core thermal power is greater than or equal to 45% of rated, the applicable Kp multiplier from Table 4-3 is applied to the applicable rated condition OLMCPR value in Table 4-1 or adjusted OLMCPR value determined by using Table 4-2. Below 45% rated thermal power, the MCPR(P) limits in Table 4-3 are applied directly.

Tables 4-1 and 4-2 are derived from Reference 2 and are valid for all Cycle 22 operating domains. Nine Mile Point Unit 1 Cycle 22 has a mid-cycle MCPR breakpoint, as defined in Table 4-1. An adder, presented in Table 4-2, is required to be applied to all limits in Table 4-1 and MCPR(P) in Table 4-3 in the event of three recirculation loop operation. Table 4-1 and 4-2 limits are bounding for both GEl 1 and GNF2 fuel types.
The appropriate MCPR(P) or Kp value may be determined by linear interpolation.
The power dependent MCPR limits are presented in Table 4-3 and are valid for both GEl 1 and GNF2 fuel types (Reference 2). When core thermal power is greater than or equal to 45% of rated, the applicable Kp multiplier from Table 4-3 is applied to the applicable rated condition OLMCPR value in Table 4-1 or adjusted OLMCPR value determined by using Table 4-2. Below 45% rated thermal power, the MCPR(P) limits in Table 4-3 are applied directly. The appropriate MCPR(P) or Kp value may be determined by linear interpolation.
The flow adjusted OLMCPR is determined by multiplying the applicable rated condition OLM CPR provided by either Table 4-1 or 4-2 by the applicable Kf multiplier given in Table 4-4. The Kf multipliers are valid for both GEl 1 and GNF2 fuel types and are documented in Reference
The flow adjusted OLMCPR is determined by multiplying the applicable rated condition OLMCPR provided by either Table 4-1 or 4-2 by the applicable Kf multiplier given in Table 4-

Exelon Nuclear - Nuclear Fuels Doc ID: COLR Nine Mile Point 1, Rev. 1 I Core Operating Limits Report for Nine Mile Point 1 Cycle 22 2.0 General Information This report provides the following cycle-specific parameter limits for Nine Mile Point Nuclear Station Unit 1 Cycle 22:

  • Maximum Average Planar Linear Heat Generation Rate (MAPLHGR)
  • Operating Limit Minimum Critical Power Ratio (OLMCPR)
  • MCPR thermal limit adjustments and multipliers (MCPR(P) or MCPR(F))
  • Three recirculation loop operation MCPR adjustment
  • LHGR thermal limit multipliers (LHGRF AC(P))
  • MAPLHGR four and three recirculation loop operation multipliers
  • Linear Heat Generation Rate (LHGR)
  • Limiting Power I Flow Line This report is prepared in accordance with Technical Specification 6.6.5 of Reference 1. Power and flow dependent limits are listed for various power and flow levels. Linear interpolation is to be used to find intermediate values. Nine Mile Point Unit I is a non-ARTs plant that utilizes ELLLA operating domain.

The data presented in this report is valid for all licensed operating domains on the operating map, including:

  • Extended Load Line Limit down to the minimum licensed core flow (i.e., 85.0% of rated) during full power operation,
  • Rated core flow is 67 .5 Mlb/hr,
  • End-of-cycle coastdown to a minimum power level of 40% of rated power,
  • Feed water temperature of no more than -I 0°F off nominal is licensed for this cycle.

Further information on the cycle-specific analyses for Nine Mile Point Unit I Cycle 22 and the associated operating domains discussed above is available in Reference 2.

Exelon Nuclear - Nuclear Fuels Doc ID: COLR Nine Mile Point 1, Rev. 1 I Core Operating Limits Report for Nine Mile Point 1 Cycle 22 3.0 MAPLHGR Limits 3.1 Technical Specification 3.1.7.a, 3.1.7.e 3 .2 Description The MAPLHGR limits for each bundle type as a function of average planar exposure is given in Tables 3-1 through 3-9. For partial loop operation, a fuel-type-dependent multiplier is used, which is shown in Table 3-10. For operation with either four or three recirculation loops in service, multiply the most limiting values shown in Tables 3-1 through 3-3 by the GE 11 value in Table 3-10 and multiply the most limiting values shown in Tables 3-4 through 3-9 by the GNF2 value in Table 3-10. The power and flow dependent multipliers for MAPLHGR have been removed and replaced with LHGRF AC(P) and LHGRF AC(F); therefore, MAPF AC(P) and MAPF AC(F) are equal to 1.0 for all power and flow conditions (Reference 2). LHGRF AC(P) and LHGRF AC(F) are addressed in Section 5.0.

'I Exelon Nuclear - Nuclear Fuels Doc ID: COLR Nine Mile Point 1, Rev. 1 I Core Operating Limits Report for Nine Mile Point 1 Cycle 22 4.0 MCPR Limits 4.1 Technical Specification 3.1.7.c, 3.1.7.e 4.2 Description 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. Tables 4-1 and 4-2 are derived from Reference 2 and are valid for all Cycle 22 operating domains. Nine Mile Point Unit 1 Cycle 22 has a mid-cycle MCPR breakpoint, as defined in Table 4-1. An adder, presented in Table 4-2, is required to be applied to all limits in Table 4-1 and MCPR(P) in Table 4-3 in the event of three recirculation loop operation. Table 4-1 and 4-2 limits are bounding for both GEl 1 and GNF2 fuel types.

The power dependent MCPR limits are presented in Table 4-3 and are valid for both GEl 1 and GNF2 fuel types (Reference 2). When core thermal power is greater than or equal to 45% of rated, the applicable Kp multiplier from Table 4-3 is applied to the applicable rated condition OLMCPR value in Table 4-1 or adjusted OLMCPR value determined by using Table 4-2. Below 45% rated thermal power, the MCPR(P) limits in Table 4-3 are applied directly. The appropriate MCPR(P) or Kp value may be determined by linear interpolation.

The flow adjusted OLMCPR is determined by multiplying the applicable rated condition OLMCPR provided by either Table 4-1 or 4-2 by the applicable Kf multiplier given in Table 4-

4. The Kf multipliers are valid for both GEl 1 and GNF2 fuel types and are documented in Reference 2. The appropriate Kfvalue may be determined by linear interpolation.

Linear interpolation should be used for points not listed in Appendix A or Appendix B of Reference 4. Power adjusted LHGR limits are required for operation with PROOS at greater than or equal to 45% RTP. Below 45% RTP, no additional limits are required. These power dependent LHGR multipliers (LHGRFAC(P)) are provided in Table 5-3 for Option Band Option A scram times and are applicable to both GEl 1 and GNF2 fuel types (Reference 2). The power adjusted LHGR is determined by multiplying the applicable Appendix A LHGR limit by the LHGR multiplier, LHGRFAC(P). The LHGRFAC(P) curves are independent of recirculation loop operability. The appropriate LHGRFAC(P) values may be determined by linear interpolation. Flow dependent LHGR multipliers (LHGRFAC(F))

are not required (Reference 2).
