00 COLR2-13 NINE MILE POINT UNIT 2 Revision 0, Cycle 13 CORE OPERATING LIMITS REPORT 2.0 MINIMUM CRITICAL POWER RATIO (ODYN OPTION B) 2.1 Limits for Technical Specification 3.2.2 For 2-Pump Operation, the Minimum Critical Power Ratio (MCPR) shall be equal to or greater than the maximum of the appropriate MCPR(P) from Figures 2c, 2d and 2f or the MCPR(F) from Figure 2e.

For Single Loop Operation, the Minimum Critical Power Ratio (MCPR) shall be equal to or greater than the Minimum Critical Power Ratio for 2-Pump Operation plus 0.02.

NOTES: I. For Figures 2a and 2b tau (or "t") defined as follows:

I = ('C. - tB) / (.A - .B) where:

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

n TB= .672 + 1.65 *[ N, / E Ni ]i"2 * .016 n n tave = (ENi T i) / (YN i) i= i=H n = number of surveillance tests performed in cycle Ni = number of active control rods measured in the i'h surveillance test Ti = average scram time to notch 39 of all rods measured in the ith surveillance test N, = total number of active rods measured in Specification 3.1.4. 1.

T= 1.0 prior to performance of the initial scram time measurements for the cycle.

2. ARTS provides for power- and flow-dependent thermal limit adjustments and multipliers, which allow for a more reliable administration of the MCPR thermal limit. The MCPR(P) curves are independent of EOC-RPT and scram time option, but are determined for other EOOS. The MCPR(P) limits for PROOS were converted to a K(P) consistent with the ARTS offrated limits. MCPR(F) is independent of Scram Time Option and all EOOS.
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 where appropriate. The OLMCPR values for all other analyzed EOOS transient events are bounded by the Normal Operation limits.
4. EOR is the End of Rated exposure as defined in the Cycle Management Report.

COLR2-13 NINE MILE POINT UNIT 2 Revision 0, Cycle 13 CORE OPERATING LIMITS REPORT 3.0 LINEAR HEAT GENERATION RATE (LHGR).

3.1 Limits for Technical 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 minimum of: 1) the limiting values shown in RSLD- 12, Revision 0, "Nine Mile Point Unit 2 Reload 12, Reload Specific Lattice Data" times the LHGRFAC(F) from Figure 3a; and 2) the limiting values shown in RSLD-12, Revision 0, "Nine Mile Point Unit 2 Reload 12, Reload Specific Lattice Data" times the appropriate LHGRFAC(P) from Figures 3b or 3c or 3d. RSLD-12, Revision 0 contains the LHGR limits for both UO2 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: ARTS provides for power- and flow-dependent thermal limit multipliers, which allow for a more reliable administration of the LHGR thermal limits. The LHGRFAC(P) curves are independent of recirculation pump trip operability, but are determined for other EOOS. The LHGRFAC (P) limits for PROOS are also presented in a manner more consistent with the ARTS offrated limits. LHGRFAC(F) is identical for all EOOS.
