PO~ER DISTRIBUTION LIMITS BASES Although it is intended that the plant will be operated with the AXIAL I

FLUX DIFFERENCE within th@ +6, -9% target Band about the target flux difference~I during rapid plant THERMAL 'POW!"R reductions, control -rod motion wi11 cau5e the G

AFD to deviate outside of the target band at redu:ed THERMAL POWER levels.

This deviation will not affect the xenon redistribution sufficiently to change the er.velope cf peaking factors which may be reached on a subsequent return to R~TED THER~AL PO~ER (with the AFD within the target band) provided the time duration cf the deviation is limited.

Accordingly, a 1 hour1.157407e-5 days 2.777778e-4 hours 1.653439e-6 weeks 3.805e-7 months penalty deviation li~it cumu:ative during the previous 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months is provided for operation outside of the target band but within the limits of Figure 3.Zm1 while at THERMAL PCVER leve1s be~ween 50% and 90% of RATED THERMAL POWER.

For THERMAL POWER levels i:et... eeil 15~ and 50% of rated THER!*~AL PO\\o.'ER, deviations of the AFD 01.itside of the target band are less significant.

The penalty of Z hours attual time reflects this reduced significance.

Provisions for monitoring the AFD are derived from the plant nuclear instrumentation system through the AFD Monitor Alarm.

A control room recorder continuously displays the auctioneered high flux difference and the target band limits as a function of power level.

A first alarm is received any time the auctioneered high flux difference exceeds the target band limits.

A second alarm is received if the AFD exceeds its allowable limits fer a cumulative time of one hour during any 24 hour2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months time period starting with the occurrence of the first alarm.

Time outside the target band is gra~hically presented on the strip chart.
