SUBJECT:

Nine Mile Point Unit 1 Docket No. 50-220 License No. DPR-63 Cycle 16 Core Operating Limits Report, Rev. 3 Gentlemen:

Attached is a copy of the Cycle 16 Core Operating Limits Report (COLR), Rev. 3, for Nine Mile Point Unit 1 (NMP 1). This revision incorporates adjustments to the Minimum Critical Power Ratio (MCPR) limits. These adjustments were made to address the condition identified in the 10 CFR Part 21 Report submitted to the NRC by GE Nuclear Energy in a letter dated August 24, 2004.

This COLR revision is being submitted pursuant to NMP1 Technical Specification 6.6.5.d.

Very truly yours, oad M U]l William C. Holston Manager Engineering Services WCH/RF/jm Attachment cc:

NINE MILE POINT UNIT 1 COLR1-16 Rev. 3 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 Tables la through le.

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 Tables la through le.

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 Tables la through le.

(*)

When hand calculations are required, the APLHGR for the respective fuel type as a function of average planar exposure, shall not exceed the limits shown in Table If during five recirculation loop operation or 98 percent of the limits shown in Table If during four or three loop operation..

NINE MILE POINT UNIT I COLR1-16 Rev. 3 2.0 MINMUM 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 1.47(1).

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

If the feedwater pump configuration as defined by Nuclear Engineering Report No. NER-1M-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.

Conservative limits for operation between 45% and 90% RTP(3) are required for operations without a backup pressure regulator. The MCPR based limit for operation without a backup pressure regulator is as shown in Figure 2b(2) (4).

2.2 Limits for Technical Specification 3.1.7.e During 3 loop operation, the Operating Limit MCPR shall be increased by 0.01.

NOTES:

(l)

Based on a 1.09 MCPR Safety Limit (SLCPR).

(2)

Based on an Operating Limit MCPR of 1.47.

(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, or 5 loop operation (note that for 3 loop operation the limit for 70% < P < 90% becomes 1.48/FRTP).

Conservative limits for operation between 45% and 90% RTP(l) are required for operations without a backup pressure regulator. The LHGR based limit for operation without a backup pressure regulator is as shown in Figure 3.

NOTE:

(l)

Below 45% and above 90% RTP no additional limits are required for operation without a backup pressure regulator.

MAPLHGRs are interpolated between exposure points for which explicit values are given. The exposure for the last MAPLHGR listed for a lattice is the maximum allowed nodal exposure for that lattice.
