Revision 0 CORE OPERATING LIMITS REPORT TERMS AND DEFINITIONS Average Planar Linear Heat Generation Rate (APLHGR)

'The Average Planar Linear Heat Generation Rate (APLHGR) shall be applicable to a specific planar height and is equal to the sum of the heat generation rate per unit length of fuel rod for all fuel rods in the specified bundle at the specified height, divided by the number of fuel rods in the fuel bundle at that height BOC Beginning of Cycle Core Maximum Fraction of Limiting Power Density (CMFLPD)

The highest value of the fraction of limiting power density which exists in the core Critical Power Ratio (CPR)

The ratio of critical power to the bundle power at the reactor condition of interest Eoc End of Cycle EOR End of Rated Conditions (i.e. cycle exposure at 100% power, 100% flow, all rods-out, all feedwater heaters in service and equilibrium xenon)

Fraction of Limiting Power Density (FLPD)

The linear heat generation rate (LHGR) existing at a given location divided by the specified LHGR limit for that bundle type FRTP Fraction of Rated Thermal Power where Rated Thermal Power equals 1850 MW K~f)

MCPR flow dependent multiplier Linear Heat Generation Rate (LHGR)

The heat generation per unit length of fuel rod. It is the integral of the heat flux over the heat transfer area associated with the fuel length MAPLHGR Maximum Average Planar Linear Heat Generation Rate Minimum Critical Power Ratio (MCPR)

The minimum in-core critical power ratio RSLD Reload Specific Lattice Data Document MDFWP

COLR1-19 NINE MILE POINT UNIT 1 Revision 0 CORE OPERATING LIMITS REPORT 1.0 AVERAGE PLANAR LINEAR HEAT GENERATION RATE (APLHGR) 1.1 Limits for Technical Specification 3.1.7.a, During power operations, the APLHGR(s) for each fuel type as a function of AVERAGE PLANAR EXPOSURE shall not exceed the limiting values shown in Table la, lb, Ic and ld 1.2 Limits for Technical Specification 3.1.7.e During partial loop operation with four recirculation loops in operation, the APLHGR as a function of average planar exposure shall not exceeed 98 percent of the limiting values shown in Table la, 1b, lc and Id.

These limits are shown in Figure 2f.

2.2 Limits for Technical Specification 3.1.7.e During 3 loop operation, the Operating Limit MCPR shall be increased by 0.02. No adjustment is needed during 4 loop operation.

NOTES:

1 Based on a 1.07 MCPR Safety Limit (SLCPR) 2 For the current exposure and feedwaterpump configuration. "Pump Combinations" are also described in operating procedure N 1-OP-16, attachment 13 3 Below 45% and above 90% RTP no additional limits are required for operation without a backup regulator 4 These limits are valid for 3, 4, and 5 loop operation. (Note that for the MCPR Limit for 70%0P<90%, ie.

MCPR Limit=(Rated OLMCPR)/FRTP, the Rated OLMCPR is as determined by 2.1 and 2.2 above.)

COLRI-19 NINE MILE POINT UNIT 1 CORE OPERATING LIMITS REPORT 3.0 LINEAR HEAT GENERATION RATE (LHGR) 3.1 Limits for Technical Specification 3.1.7.b During power operation, the Linear Heat Generation Rate (LHGR) of any rod in any fuel assembly at any axial location shall not exceed the limiting values shown in RSLD-20, Revision 0, "Nine Mile Point Unit 1 Reload 20, Reload Specific Data".

This document contains the LHGR limits for both U02 rods (which contain no gadolinium) and the most limiting gadolinium-bearing rods. Other gadolinium-bearing rods have LHGR limits which lie between thesetwo curves. Compliance with these limits will be monitored by the plant's process computer.

Additional limits for operation between 45% and 90% RTP(1) are required for operations without a backup pressure regulator. These limits are shown in figure 3.

NOTE:

1 Below 45 % and above 90% RTP no additional limits are required for operation without a backup pressure regulator.

MAPLHGRs are interpolated between exposure points for which explicit values are given.

(2) These MAPLHGRs are not lattice dependent, therefore the values shown also correspond to the limiting value for the most limiting lattice for use when hand calculations are required.
