5. CONTROL ROD POSITION INDICATION If either the power range channel deviation alarm or the rod deviation monitor alarm are not operable rod positions shall be logged once per shift and after a load change greater than l(5 of rated power. If both alarms are inoperable for two hours or more, the nuclear overpower trip shall be reset to 935 of rated power.

6. POWER DISTRIBUTION L IHITS

a. Hot channel factors:

(1) With steam generator tube plugging >225 and <25K, the hot channel factors (defined in the basis) must meet the following limits at all times except during low power physics tests:

Fq (Z) < (2e03'/P)x K(Z) > for P > ~ 5 Fq (Z) < (4.06) x K(Z), for P < .5 F

H

< 1.55 [l.+0.2 (1-P) j Where P 'is the fraction of. rated power at which the core is operating; K(Z) is the function given in Figure 3.2-3b; Z is the core height location of Fq If F , as predicted by approved physics calculations, exceeds 2.03, the power will be limited to the rated power multiplied by the ration of 2.03 divided by the predicted F , or augmented surveil.lance of hot channel factors shall be implemented.

(2) With steam generator tube plugging < 22K, the hot channel factors (defined in the basis) must meet the following limits at all times except during low power physics tests:

Fq (Z) <'2e 10/P )x K(Z) p for P > e5 F (Z) < (4.20)x K(Z), for P < .5 F

H

< 1.55 [1.+0.2 ('1-P)]

Where P is the fraction of rated power at which the core is operating; K(Z) is the function given in either Figure 3.2-3 or 3.2-3a; Z is the core height location of Fq.
