SUBJECT:

Nine Mile Point Nuclear Station Renewed Facility Operating License No. NPF-69 Unit No. 2; Docket No. 50-410 Core Operating Limits Report Enclosed is a copy of the Core Operating Limits Report, COLR2-14, Revision 2 for Nine Mile Point Unit 2 (NMP2). This report is being submitted pursuant to NMP2 Technical Specification 5.6.5.d. The COLR is being revised to provide a more robust description of Linear Heat Generation Rates (LHGR) values and their source documentation based on an internal Quality Assurance observation.

Should you have any questions regarding the information in this submittal, please contact Everett P.

The limits of Table I shall be reduced to a value of 0.78 times the two recirculation loop operation limit when in single recirculation loop operation.

Il COLR2-14 NINE MILE POINT UNIT 2 Revision 2, Cycle 14 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 2e or the MCPR(F) from Figure 2f.

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: l. For Figures 2a and 2b tau (r) defined as follows:

= - rB T'4 - TB where:

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

S=0.672+1.65 x(0.016)

ZN, i=1 n = number of surveillance tests performed in cycle N, = number of active control rods measured in the i'h surveillance test ri = 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

= 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 offi'ated 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.
5. The K(P) multiplier at P-bypass (26% power) for PROOS has been adjusted to match the EIS condition in order to add conservatism under the PROOS condition.

a. The flow-dependent multiplier, LHGRFAC(F), from Figure 3d, or
b. The power-dependent multiplier, LHGRFAC(P), from Figures 3a, 3b, or 3c.

NOTES: 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.
