BASES l
AXIAL FLUX DIFFERENCE (Continued)
Although it is intended that the plant will be operated with the AFD within the target band required by Specification 3.2.1 about the target flux difference, during rapid plant THERMAL POWER reductions, control rod motion will cause the AFD to deviate outside of the target band at reduced THERMAL POWER levels.
This deviation will-not affect the xenon redistribution sufficiently to change the envelope of peaking factors which may be reached on a sub:;equent return to RATED THERMAL POWER (with the AFD within the target band) provided the time duration of the deviation is limited. Accordingly, a j
1-hour penalty deviation limit cumulative during the previous 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> is provided for operation outside of the target band but within the limits 3-1-
specified in the OPERATING LIMITS REPORT while at THERMAL POWER levels between l l
50% and 90% of RATED THERMAL POWER.
For THERMAL POWER levels between 15% and i
50% of RATED THERMAL POWER, deviations of the AFD outside of the target band i
are less significant. The penalty of 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> actual time reflects this reduced d
significance.
Provisions for monitoring the AFD on an automatic basis are derived from the plant process computer through the AFD Monitor Alarm. The computer deter-mines tha 1-minute average of each of the OPERABLE excore detector outputs and provides an alarm message immediately if the AFD for two or more OPERABLE excore channels are outside the target band and the THERMAL POWER is greater than 90% of RATED THERMAL POWER. During operation at THERMAL POWER levels between 50% and 90% and between 15% and 50% RATED THERMAL POWER, the computer outputs an alarm message when the penalty deviation accumulates beyond the limits of I hour and 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br />, respectively.
Figure B 3/4 2-1 shows a typical monthly target band.
3/4.2.2 and 3/4.2.3 HEAT FLUX HOT CHANNEL FACTOR. and RCS FLOWRATE AND NUCLEAR ENTHALPY RISE HOT CHANNEL FACTOR The limits on heat flux hot channel factor, RCS flowrate, and nuclear enthalpy rise hot channel factor ensure that: (1) the design limits on peak local power density and minimum DNBR are not exceeded, and (2).in the event of a LOCA the peak fuel clad temperature will not exceed the 2200*F ECCS acceptance criteria limit.
Each of these is measurable but will normally only be determined periodically as specified in Specifications 4.2.2 and 4.2.3.
This periodic surveillance is sufficient to insure that the limits are maintained provided:
a.
Control rods in a single group move together with no individual rod position differing by more than 12 steps, indicated, from the group demand position, b.
Control rod groups are sequenced with overlapping groups as described in Specification 3.1.3.6, BRAIDWOOD - UNITS 1 & 2 B 3/4 2-2 AMENDMENT NO. 80
