1 F0WER DISTRIBUTION LIMITS BASES 3/4.2.2 and 3/4.2.3 HEAT FLUX ANC NUCLEAR Ef1THALPY HOT CHAttriEL FACTORS-I F(Z)andF[g 0

The limits on heat flux and nuclear enthalpy hot channel factors ensure tnat 1)' tne cesign limii.s un peak local power der.;ity arid minim = 0.90.'l cr:

not exceeded and 2) in the event of a LOCA the peak fuel c will not exceed the ECCS acceptance criteria limit of 2200[ad temperature F.

Each of these hot channel factors are measurable but will nomally only be detemined periodically as specified in Specifications 4.2.2 and 4.2.3.

This periodic surveillance is sufficient to insure that the hot channel factor limits are maintained provided:

a.

Control rod in a single group move together with no individual rod insertion differ.ing.by more than + 12 steps fecm the group denand position.

b.

Control rod groups are sequenced with overlapping groups as described in Specification 3.1.3.5.

c.

The control rod insertion limits of Specifications.3.1.3.4 and 3.1.3.5 are maintained.

d.

The axial power distribution, expressed in tems of AXIAL FLUX

~

DIFFEREt1CE is maintained within the limits.

The relaxation in F as a function of THERMAL POWER allows changes H

in the radial power shape for all permissible rod insertion limits.

F g

will be maintained within its limits provided conditions a thru d above,

-are maintained.

When an F measurement is taken, both experimental error and manufacturing g

tolerance must be allowed for. 5% is the appropriate experimental error allowance for a full core map taken with the incore detector flux mapping system and 3% is the appropriate allowance for manufacturing tolerance.
