OPERA TING LIMITS NUMBER COLR2 REVISION 15 PAGE 2 OF 16 UNIT 2

The cycle-specific parameter limits for the TS listed in Section l are presented in the following subsections. These limits have been developed using the NRC-approved methodologies specified in TS 5.6.5.

2.1 Shutdown Margin (SDM) (TS 3.1.1, 3.1.4, 3.1.5, 3.1.6, 3.1.8)

The SDM limit for MODE 1, MODE 2, MODE 3 and MODE 4 is:

2.1. l The shutdown margin shall be greater than or equal to 1.6% L-.k/k.

2.1.2 In MODES 3 or 4 the shutdown margin with Safety Injection blocked shall be greater than or equal to 1.6% b.k/k calculated at a temperature of 200°F.

The SDM limit for MODE 5 is:

2.1.3 The shutdown margin shall be greater than or equal to 1.6% L-.k/k. This limit addresses the concerns ofNSAL-02-014 (Reference 6.3) and the boron dilution analysis for RCS filled conditions.

In order to address RCS drained conditions for the boron dilution analysis, a minimum boron concentration of 1800 ppm shall be maintained whenever the RCS level is at or below the reactor vessel flange elevation (114 feet).

2.2 Moderator Temperature Coefficient (MTC) (TS 3.1.3)

The MTC limit for MODES 1, 2, and 3 is:

2.2.1 The MTC shall be less negative than -3. 9x 10-4 L-.k/k/°F for all rods withdrawn, end of cycle life (EOL), RATED THERMAL POWER condition.

2.2.2 The MTC 300 ppm surveillance limit is -3.0x10-4 b.k/k/°F (all rods withdrawn, RATED THERMAL POWER condition).

2.2.3 The MTC 60 ppm surveillance limit is -3.72x10-4 6k/k/°F (all rods withdrawn, RA TED THERMAL POWER condition).

2.3 Shutdown Bank Insertion Limits (TS 3.1.5) 2.3.1 Each shutdown bank shall be withdrawn to at least 225 steps.

2.4 Control Bank Insertion Limits (TS 3.1.6) 2.4. 1 The control banks shall be limited in physical insertion as shown in Figure I.

2.4.2 The control banks shall be withdrawn and inserted in the prescribed sequence in accordance with plant operating procedures. For withdrawal, the sequence is contrnl bank A, contrnl bank B, control bank C, and control bank D. The insertion sequence is the reverse of the withdrawal sequence.

2.4.3 A 128 step tip-to-tip relationship between each sequential control bank shall be maintained.

For T(Z) data at a desired bumup not listed in the table, but less than the maximum listed burnup, values at 3 or more burnup steps should be used to interpolate the T(Z) data to the desired bumup with a polynomial type fit that uses the T(Z) data for the nearest three burnup steps.

For T(Z) data at a desired burnup outside of the listed burnup steps, a linear extrapolation of the T(Z) data for the nearest two burnup steps can be used. If data are listed for only 2 burnup steps, a linear fit can be used for both inte1polation and extrapolation.

The T(Z) values are generated assuming that they will be used for full power smveillance. When using a flux map instead of the Power Distribution Monitoring System (PDMS) for part power surveillance, the T(Z) values must be increased by the factor 1/P (P > 0.5) or 1/0.5 (P :S 0.5), where P is the core relative power duiing the smveillance, to account for the increase in the FQ(Z) limit at reduced power levels.

Rj penalty factors account for the potential decrease in transient FQ margin between smveillances. The Rj factors for ROSI and ROS2 are provided in Tables lA and lB, respectively. These values shall be used to increase FJv (Z) per SR 3.2.1.2.

Either ROSl or ROS2 may be implemented at any time during operation.

If ROS I is implemented and entering LCO 3.2.1 Condition B for F~v ( Z) not within limits, EITHER take Action B.1.1 and implement ROS2, OR take Action B.2. 1 by using Table 3 to determine required THERMAL POWER and AFD limits based on Required F~v (Z) margin improvement.

IfROS2 is implemented and entering LCO 3.2.1 Condition B for F~v (Z) not within limits, take Action B.2. l by using Table 3 to determine required THERMAL POWER and AFD limits based on Required F~v (Z) margin improvement.

b.

Increasing the measured FQ(Z) component of the power distribution map by 3% to account for manufacturing tolerances and further increasing the value by 5% to account for measurement uncertainties.
