-NOTE: (1) A "-" indicates that there is no entry for this box and the limit can be determined by linearly ifiterpolating between the previous and next point in each column. MAPLHGRs are interpolated between exposure points for which explicit values are given.

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

Revision 1 Cycle 11 NINE MILE POINT UNIT 2 CORE OPERA TING 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 for GE14 and Figures 2a-11 and 2b- 11 for GEl 1 times the K(f) shown in Figure 2c with tau (or "T")

defined as follows:

T (Tae TB)/(TA TB) where:

TA 0.866 seconds; control rod average scram insertion time limit to notch 39 per Specification 3.1.4.

n TB =. 6 72 + 1.6 5 *[ N1 /Z Ni ]" 2 .016 n n Tave= i j) /N(EN i n = number of surveillance tests performed in cycle Ni= number of active control rods measured in the ih surveillance test

=i average scram time to notch 39 of all rods measured in the ith surveillance test N1 = total number of active rods measured in Specification 3.1.4.1.

NOTES: 1. The MCPR Operating Limits in Figures 2a- 11, 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 MCPRfor single loop operation.

2. T= 1.0 prior to performance of-the initial scram time measurements for the cycle.
3. The Operating Limit MCPR 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, 2b-14, 2a-1 1, and 2b-1 l.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-1 1 is the End of Rated exposure as defined in the Cycle Management Report Page 3 of 19

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 3-11 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.
