1.0 INTRODUCTION
910 DISCUSSION By letter dated May 14,1980 (Reference 1) Consumer's Power Company (CPCo),
(the licensee) requested an amendment to Appendix A of the Provisional Goerating License No. DPR-20 for the Palisades Plant.
This is the third in a series of related requests, pertaining to the peaking factors of the Cycle-4 H-design loading.
CPCo was requested by letter from D. Zienann (NRC) to D. Bixel dated July 11,1979 (Reference 2), to submit information which would provide assurance that water hole peaking is appropriately considered in the calculation of flux distributions.
CPCo's replies dated September 10, 1979 and February 26,1980 (letters D. Hoffman CPCo to D. Ziemann NRC, References 3 and 4 respectively) dealt with the 4
calculational procedure used to compute water hole peaking. CPCo by letter dated February 26, 1980 submitted information succorting the addition of the " Total Interior Rod Ldial Peaking Factor F$H". The licensee considered it appropriate to impose a limit on the product of total radial peaking factor times the interior pin local peaking facto.r to assure that the assumptions in the DNS analysis remain valid in all cases.
This proposed addition has been reviewed and accepted by the NRC staff (Reference 5).
The current request (Reference 1) concerns a change of the Palisades Plant Technical Specifications to increase the limit of the Total Radial Peaking Factor FrT for Type H fuel assembly rods adjacent to the wide water gap from 1.77 (1.0 + 0.5 (1-P)) to 1.90 (1.0 + 0.5 (1-P))
where P is the core thermal power in fraction of core rated thermal power (2530 Mwt). This increase is only for the Cycle 4 loading and will allow operation at full power for the total fuel cycle, whereas operation under the present Technical Specifications will result in plant operation derated by 12% power for part of this cycle.
