PC/M 08032, Rev 0 Attachment 14, Page 5 of 13 1.65 2.5 Total Integrated Radial Peaking Factor - FrT (TS 3.2.3)

The calculated value of FrT at RATED THERMAL POWER shall be limited to  1.70 The power dependent FrT limits are shown on Figure 3.2-3.

2.6 DNB Parameters - AXIAL SHAPE INDEX (TS 3.2.5)

The AXIAL SHAPE INDEX shall be maintained within the limits specified in Figure 3.2-4.

New Text The following DNB-related parameters shall be maintained within the limits shown on Table 3.2-1:

a. Cold Leg Temperature
b. Pressurizer Pressure
c. Reactor Coolant System Flow rate
d. AXIAL SHAPE INDEX 2.7 Refueling Operations - Boron Concentration (TS 3.9.1)

With the reactor vessel head unbolted or removed, the boron concentration of all filled portions of the Reactor Coolant System and the refueling cavity shall be maintained uniform and sufficient to ensure that the more restrictive of the following reactivity conditions is met:

a. Either a Keff of 0.95 or less, which includes a 1000 pcm conservative allowance for uncertainties, or 1900
b. A boron concentration of  1720 ppm, which includes a 50 ppm conservative allowance for uncertainties.

2.8 SHUTDOWN MARGIN - Tavg Greater Than 200 0F (TS 3.1.1.1)

The SHUTDOWN MARGIN shall be greater than or equal to 3600 pcm.

2.9 SHUTDOWN MARGIN - Tavg Less Than or Equal To 200 0F (TS 3.1.1.2)

The SHUTDOWN MARGIN shall be greater than or equal to 2000 pcm.
