C- .7 NINE MILE POINT UNIT 1 COLRI-17 Rev. 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 operation, the APLHGR for each type of fuel as function of average planar exposure shall not exceed the limiting values shown in Table 1.

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 exceed 98 percent of the limiting values shown in Table 1.

During partial loop operation with three recirculation loops in operation, the APLHGR as a function of average planar exposure shall not exceed 98 percent of the limiting values shown in Table 1.

NINE MILE POINT UNIT 1 COLR1-17 Rev. 0 2.0 MINIMUM CRITICAL POWER RATIO (MCPR) 2.1 Limits for Technical Specification 3.1.7.c During power operation, the operating MCPR at rated power and flow shall be greater than or equal to the Operating Limit MCPR of:

1.48(') for cycle exposures(2) from BOC19 to EOR19-2417 MWd/ST, and 1.53(l) for cycle exposures(2) from EORI 9-2417 MWd/ST to EOC 19.

If the feedwater pump configuration, as defined by Nuclear Engineering Report No. NER-IM-022, is such that a feedwater controller failure could result in maximum feedwater flow greater than that for two feedwater pumps (i.e., the shaft-driven pump plus one motor-driven pump), then the Operating Limit MCPR shall be 1.59.

For core flows other than rated, the MCPR limit shall be the Operating Limit MCPR identified above times Kf where Kr is as shown in Figure 2a.

Additional limits for operation between 45% and 90% Rated Thermal Power (RTP) (3) (4) are required for operations without a backup pressure regulator.

These limits are shown in Figure 2b.

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) These cycle exposures are defined in the Cycle Management Report 3 Below 45% and above 90% RTP no additional limits are required for operation without a backup pressure regulator.

(4) These limits are valid for 3, 4, and 5 loop operation. (Note that for the MCPR Limit for 70% < 90%, i.e. MCPR Limit =

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

NINE MILE POINT UNIT 1 COLR1-17 Rev. 0 3.0 LINEAR HEAT GENERATION RATE (LHGR) 3.1 Limits for Technical Specification 3.1.7b 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-18, Revision 0, "Nine Mile Point Unit 1 Reload 18, Reload Specific Lattice 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 these two curves. Compliance with these limits will be monitored by the plant's process computer.

Additional limits for operation between 45% and 90% RTP(t ) 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.

(1) A "-" indicates that there is no entry for this box and the limit can be determined by linearly interpolating between the previous and next point in each column.

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

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