a.

Control Banks A and B shall be withdrawn to at least 225 steps.(2)

b.

Control Banks C and D shall be limited in physical insertion as shown in Figure 5.1-2.(2)

c.

Sequence Limits - The sequence of withdrawal shall be A, B, C and D bank, in that order.

d.

Overlap Limits(2) - Overlap shall be such that step 129 on banks A, B, and C corresponds to step 1 on the following bank. When C bank is fully withdrawn, these limits are verified by confirming D bank is withdrawn at least to a position equal to the all-rods-out position minus 128 steps.

If there are less than 75% of the total number of thimbles and at least 50% of the total number of thimbles measured, an additional uncertainty of (0.01)*(3-T/12.5) is added to the measurement uncertainty, 1.05, where T is the total number of measured thimbles. This adjusted measurement uncertainty is then multiplied by 1.03 to obtain the total uncertainty to be applied. At least three measured thimbles per core quadrant are also required.

is the measured planar radial peaking factor and is equal to the value of FQ MZ/PMZ, where PMZ is the measured core average axial power shape.

The T(Z) values in Tables 5.1-1 and 5.1-2 were generated assuming that they will be used for a full power surveillance, applicable to RAOC Operating Space (ROS) #1 and #2, respectively. The Rj values in Table 5.1-3 and 5.1-4 were generated to account for the increase in FQ between surveillances, applicable to ROS #1 and #2, respectively. The AXYZ factors adjust the surveillance to the reference conditions assumed in generating the T(Z) factors. AXYZ may be assumed to equal 1.0 or may be determined for specific surveillance conditions using the approved methods listed in TS 5.6.3.

Either ROS1 or ROS2 may be implemented at any time during operation.

If ROS1 is implemented and entering LCO 3.2.1 Condition B for FQ WZ not within limits, EITHER take Action B.1.1 and implement ROS2, OR take Action B.2.1 by using Table 5.1-5 to determine required THERMAL POWER and AFD limits based on Required FQ WZ margin improvement.

If ROS2 is implemented and entering LCO 3.2.1 Condition B for FQ WZ not within limits, take Action B.2.1 by using Table 5.1-5 to determine required THERMAL POWER and AFD limits based on Required FQ WZ margin improvement.

The AFD acceptable operation limits for both ROS1 and ROS2 are provided in Figure 5.1-4.

An additional uncertainty is to be applied if the number of measured thimbles for the moveable incore detector system is less than 75% of the total number of thimbles. If there are less than 75% of the total number of thimbles and at least 50% of the total number of thimbles measured, an additional uncertainty of (0.01)*(3-T/12.5) is added to the standard uncertainty on FNH of 1.04, where T is the total number of measured thimbles. At least three measured thimbles per core quadrant are also required.
