Revision 0 cycle 11 NINE MILE POINT UNIT 2 CORE OPERATING LIMITS REPORT 2.0 MINIMUM CRITICAL POWER RATIO (ODYN OPTION B) 2.1 Limits for Technical Specification 3.2.2 The Minimum Critical Power Ratio (MCPR) shall be equal to or greater than the appropriate MCPR limit from Figures 2a-14 and 2b-14 fbr GE14 and Figures 2a-11 and 2b- I1I for GEI I times the K(f) shown in Figure 2c with tau (or "'t')

defined as follows:

T = (T. - T,) / (tA -

where:

T^, = 0.866 seconds, control rod average scram insertion time limit to notch 39 per Specification 3.1.4.

,=672+ 1.65 * £ N, I Nj * .016 2 n i.1 i-i n = number of surveillance tests performed in cycle Ni= number of active control rods measured in the iP surveillance test r, =:average scram time to notch 39 of all rods measured in the i? surveillance test N, = total number of active rods measured in Specification 3.1.4.1.

NOTES: i. The MCPR Operating Limits in Figures 2a-t 1, 2a-14, 2b-11 and 2b-14:are based on a 1.07 Safety Limit MCPR (SLMCPR) for two recirculation loop operation and a 1.09 Safety Limit MCPR for single loop operation.

2. r = 1.0 prior to performance of the initial scram time measurements for the cycle.
3. The Operating Limit MCR values for Turbine Bypass Out of Service and EOC-RPT Out of Service are higher (more limiting) than for the standard normal operation case, and are therefore specifically identified in Figures 2a-14, 21,4, 2a-1 1J and 2b-1 I.The OLMCPR values for all other analyzed EOOS transient events are bounded by the Normal Operation limits.
4. For operation between 30% and 90% RTP with a backup pressure regulator out of service, additional MCPR limit requirements have been established in Figures 2d and 2e.
5. EOR on Figures 2a-14, 2b-14, 2a-11, and 2b-ll is the End of Rated exposure as defined in the Cycle Management Report Page 3 of 19

Revision 0 Cycle 11 NINE MILE POINT UNIT 2 CORE OPERATING LIMITS REPORT 3.0 LINEAR HEAT GENERATION RATE (LHGR) 3.1 Limits forTechnical Specification 3.2.3 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-10, Revision 0, "Nine Mile Point Unit 2 Reload 10, 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.

NOTE: For operation >30% and <90% RTP with a backup pressure regulator out of service, additional LHGR limit requirements have been established as shown in Figure 3-1 1 and 3-14. There are no additional LHGR limits required for operation

<30% and >90% RTP for operation with a backup pressure regulator out of service.
