O ATTACHSENT 2 Zion Station Units 1 and 2 NRC Docket Nos. 50-295 and 50-304 Revisions to Proposed Technical Specification Changes Page: 45 and 63a of Reference (a) should be replaced with the following pages 45 and 63a 810.4230 %25
LIMITING CONDITION FOR OPERATION SURVEILLANCE REQUIREMENT 3.2.2 Power Distribution Liniits 4.2.2 Power Distribution A.
Hot Channel Factor Limits
- A.
Hot Channel Factor Limits 1.1 At all times, except durir.g physics tests 1.1 Following initial core loading and at < 75% rated power **, the hot channel.
at a minimum of regular effective factors defined in the bases must mect full power monthly intervals the folloving limits:
thereafter, power tistribution maps, using the movoble detector system, shall be mac* to confirm Units 1 & 2 that the hot channel factor limits f
Fg(Z)< [Fg(Z)] = 2.17/P x K (Z), for P>.5' of this specification are
~
1 satisfied.
L.4.34 x K (Z,), for P<.5 j

and FN <l.55[l+0.2(1-P)] X RBP,
.Following. initial loading and each aH-subsequent reloading, and power distribution map using the movable Detector system, shall be made to where:
confirm that power distribution limits are met, in the full power
[Fg(Z)] = Fg(Z) limit; configuration before E unit is L
operated above 75% of rating.
2.17 = Fg constant (LOCA limiting value);
P = fraction of rated power at which the core N
operated during Fg and F measurement; LH X (Z) = factor from Figure 3.2-9 selected at the 1core elevation, Z, of the measured Fg; The hot channel factors above aIe defined for a period not to exceed the predicted minimum time to collapse exposure levels for each fuel region as referenced in the bases.
During Physics tests which may exceed these hot channel factor limits, the reactor.may be in this condition for a period of time not to exceed eight hours continuously.
