Insert With the f eedwater temperature between 400'F and 320*F and with 1 this temperature deviating more than 5'F from that temperature l shown in Figure 3.2.3-3 for the given power level, increase the l operating limit MCPR by 0.03.

With the feedwater temperature between 320'F and 250*F and with this temperature deviating more than 5'F from that temperature l shown in Figure 3.2.3-3 for the given power level, increase the operating limit MCPR by 0.06.
