Core Operating Limits Report l 1.0' INTRODUCTION The Core Operating Limits Report (COLR) for Plant 11atch Unit 1 Cycle 17 is prepared in accordance with the requirements of Technical Specification 5.6.5. The core operatlag limits presented herein were developed using NRC approved metto ;s (References 1 and 2). Results from the fuel vendor's reload analy.4 for the fuel in Unit ! Cycle 17 are documented in References 3 through 7.

l The following core operating limits are included in this report:

a. Control Rod Block Instrumentation Technical Specification ;' 3.2.1

b. Average Planar Linear lleat Generation Rate (APLliOR) Technical Specification 3.2.1 l

c. Minimum Critical Power Ratio (MCPR) Technical Specifications 3.2.2 and 3.3.2.1

d. APRM Flow Blased Simulated Thermal Power liigh - Technical Specifications Surveillance Requirement 3.3.1.1.14 2.0 ROD BLOCK MONITOR (Technical Specification 3.3.2.1)

Both Rod Block Monitor (RBM) channels shall be operable as specified in Technical Specification 3.3.2.1 and when:

a. Thermal Power in 2 29% and < 90% of Rated Thermal Power, and MCPR is < l 70; of l-b.- ' Thermal Power is 2 90% of Rated Thermal Power, and MCPR is < l A0.

The APLilGR limit for each fuel type is given by the applicable rated power, rated flow APLilOR limit taken from Figures 3 3 through 3 9, multiplied by the smaller of either:

a. The flow dependent multiplier, MAPFACr. from Figure 3 1, or

b. The power-dependent multiplier, MAPFACp, from Figure 3 2A or F.lgure 3 2B, as determined by Table 31.

For the fuel types whose APLilGR limits are shown in Figures 3 3 through 3 9, the l APLiiOR limit shall be applied to each axial location in the fuel assembly.

As required by GESTAR ll (Reference 1),if the APLllOR values are hand calculated, all of the lattices in a multi lattice fuel bundle (i.e., OE9B P8DWB330100Z-80M 150 T, OE9B P8DWB331 100Z 80M 150 T, OE13 P911TD327120Z 100M 146 T LUA.

RECON,GE9B P8DWB346100Z 80U 150 T, OE12 P1011SB331605.0/404.0100T- 4 150 T, and OE9B P8DWB331 100Z 80M 150 T MAPL) must have APLl40R values )

less than or equal to the APLilGR limits shown in Figures 3 3,3 5,3 6,

• 7. 3 8 and 3 9 respectively. When APLilGR values are determined by the process computer, the lattice.

dependent APLilGR limits are used. Under these conditions, some axial locations may have APLilGR values exceef.ng the values shown in the figures.

Core Operating Limits Report i 4.0 MCPR OPERATING LIMITS (Technical Specification 3.2.2)

The MCPR operating limit (OLMCPR) for each fuel type is a function of core power, core flow, average scram time, number of operating recirculation loops, operability of the end of cycle recirculation pump trip (EOC RPT) system, operability of the turbine bypass valves and number of operating turbine pressure regulators.

.With both recirculation pumps in operation (TLO), the OLMCPR for each fuel type with

- various combinations of equipment operability, scram times, core power and core flow is determined as follows:

a. For 25% s power < 30%, the power dependent MCPR limit is given in Figure 41. l

b. For power h 30%, the OLMCPR is the greater of either:

1) The product of the appropriate value from Figure 4 2A or Figure 4 2B and the appropriate value from Figures 4-4A through 4 4D, as determined by Table 4-1, or

2) The flow dependent MCPR limit determined from the applicable maximum core flow limit line of Figure 4 3. -

With only one recirculation pump in operation (SLO), the OLMCPR for each fuel type is the TLO OLMCPR plus 0.01.

Operation with intermittent feedwater temperature reduction is included in the MCPR limits presented in Figures 4 4A through 44D.

In Figures 4-4A through 4 4D, Option A scram time MCPR limits correspond to t = 1.0, where t is determined from scram time measurements performed in accordance with Technical Specifications Surveillance Requirements 3.1.4.1 and 3.1.4.2. Option B values l correspond to t = 0.0. For scram times between Option A and Option B, the MCPR limit for each fuel typ. + ysponds to T. If t has not been determined, Option A limits are to be used. Refer to ~ @s 41 to determine the applicable set of fuel type dependent curves.
