PROPOSED CHANGE AXIAL FLUX DIFFERENCE TECHNICAL SPECIFICATION SALEM UNIT NO. 1 Description of Change Change the axial flux difference target band to +6,-9% about the target flux difference.
Reason for Change Increased flexibility for operating the unit under Constant Axial Offset Control {CAOC), especially during power change maneuvers.
Safety Evaluation An analysis of total peaking factor versus core height for normal plant operation has been performed for Salem Unit 1 starting with a cycle 2 core burnup of 3000 MWD/MTU. The bases for the analyses included CAOC with +6, -9% Li. I control band and that the limit on F at fractional thermal power was modified to include a multiplie£Ychange from 0.2 to 0.3. The power peaking calculations were performed using the 18 case analysis discussed in the "Westinghouse Reload Safety Evaluation Methodology", WCAP-9273, and documented in a Westinghouse letter from c. Eicheldinger to D. B. Vassallo of the NRC {NS-CE-687 dated July 16, 1975). NRC approval to use the 18 case analysis for.:1I bandwidening was given in a letter from D. B. Vassallo to c. Eicheldinger, dated April 15, 1976. The results of these calculations are shown in figure 1. It can be seen that F 0 x Power satisfied the generic FAC boundry with the +6, -9%A.I Earget band and the revised multiplier on the Fxv limit at fractional thermal power. fore, the peaking factor and DNBR criteria are met with margin for the +6, -9%.A I band and revised Fxy limit at fractional thermal power.

- POWER DISTRIBUTION LIMITS BASES . c+(p1-'1%
Although it is intended plant will be operated with the AXIAL FLUX DIFFERENCE within the band 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 duced THERMAL POWER levels. This deviation will not affect the xenon redistribution sufficiently to change the envelope of peak.,ing factors which may be reached on a subsequent return to RATED THERMAL POWER (with *the AFO within the target band) provided the time duration of the ation is limited. Accordingly, a 1 hour* penalty deviation limit lative 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 of Figure 3.2-1 while at THERMAL POWER levels between 50% and 90% of RATED THERMAL POWER. For THERMAL POWER levels between 15% and of rated THERMAL POWER, deviations of the AFC.outside of the target band 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 Provisions for monitoring the AFD are derived from the plant nuclear instrumentation system through the AFO Monitor Alarm. A control room recorder continuously 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 AFC exceeds its allowable limits for a cumulative time of one hour during any 24 hour* time period starting with the occurrence of the first alarm. Time side the target band is graphically presented on the strip chart. Figure B 3/4 2-1 shows a typical monthly target band. SALEM -UNIT 1 B 3/4 2-2 '

- PROPOSED CHANGE HEAT FLUX HOT CHANNEL FACTOR -FQ(Z) TECHNICAL SPECIFICATION SALEM UNIT NO. 1 Description of Change Modify the limit on F at fractional thermal power by changing the multiplier from to 0.3 as follows: F L = F RTP[l + 0.3(1-P)]
xy xy Reason for Change Allow optimization of core loading patterns at hot full power conditions without incurring a restrictive F limit at low power. This could lead to increased fuel utllization, since fresh *or depleted burnable poison rod assemblies are often used to flatten power at reduced power level at the expense of cycle lifetime.
Safety Evaluation Included in safety evaluation on proposed change to Axial Flux Difference Technical Specification.

Using the movable incore detectors to obtain a power tion map at any THERMAL POWER greater than 5% of RATED THERMAL POWER. Increasing the measured Fxv component of the power distribution map by 3% to account for manufacturing tolerances and further increasing the value by 5% to account for measurement uncertainties.
Comparing the Fxy computed (Fx;) obtained in b, above to: 1. The Fxy limits for RATED THERMAL POWER for the appropriate measured core planes given in e and f below, and 2. The relationship:
