~
UNI.L1 1
The Unit-entered the reporting period at a power level of 1017 MWe (97%
reactor power).
The unit remained on line the entire report period ending at a power level of 1073 MWe (99.5% reactor power) and having an availability. factor of.100.0%.
f UNIL2 The unit entered the. report period at a power level of 350 MHe (381
-reactor power). On 9/7/90 at 1949 hours0.0226 days <br />0.541 hours <br />0.00322 weeks <br />7.415945e-4 months <br /> the unit had a turbine / reactor trip due to condenser boot failure.
On 9/20/90 at 2245 hours0.026 days <br />0.624 hours <br />0.00371 weeks <br />8.542225e-4 months <br /> the rcactor i
became critical and on 9/22/90 at 1458 hours0.0169 days <br />0.405 hours <br />0.00241 weeks <br />5.54769e-4 months <br /> the unit was synchronized to the grid.
On 9/22/90 at 2151 hours0.0249 days <br />0.598 hours <br />0.00356 weeks <br />8.184555e-4 months <br /> unit two had a 2H main transformer explosion and fire. -The unit remained off-line the remainder of the reporting period.

Questions:
1.
Name of facility.
2.
Scheduled date for next refueling shutdown.
3.
Scheduled date for 1-estart following refueling.
4.
Will refueling or resumption of operation thereafter require a technical specification change or other license amendment?
If answer is yes, what, in general, will these be?
bee'n,nswer is no, has the reload fuel design and core configuration f
If a reviewed by your Plant Safety Review Committee to determine.
whether any unreviewed-safety questions are associated with the core reload (Ref. 10 CFR Section 50.59)?
If no such review has taken place, when is it scheduled?
5.
Scheduled date(s) for submitting proposed licensing action-and
-supporting information.
]
6.
Important licensing considerations associated with refueling, e.g.,
new or different fuel design or supplier, unreviewed design or performance analysis methods, significant changes in fuel design, new I
operating procedures, s
7.
The number of fuel assemblies: (a) in the core and (b) in the spent
'a fuel storage pool.
8.
The present licensed-spent fuel pool storage capacity and the size of j
any increase in licensed storage capacity that has been requested or is planned, in number of fuel assemblies.
-i 9.
The projected date of the last refueling that can be discharged to the spent fuel pool assuming the present licensed capacity.

3.
Cycle 13 is scheduled to start up November 11, 1991..
4.
-Yes.
Technical Specification changes will be required to include the 4
Westinghouse VANTAGE fuel design being loaded for Z1C13.-and effects j
of the vessel fluence reduction program beginning with Z1C13.
5.
License amendments for the Z1C13 reload are expected to be submitted.
In the Fall / Hinter of 1990.
6.
License considerations associated with the 21C13' reload include the new VANTAGE fuel design, and the new LOCA analysis with higher core power peaking factors required for the low-low-leakage loading pattern used in ZlC13.
7.
The number of fuel assemblies i
a) in the core is 193, and b) in the spent fuel storage pool from Zion Unit 1 is 708.
8.
The present licensed spent fuel pool storage capacity (shared'with Zion Unit 2) is 2112 fuel assemblies.
Plans-are being developed to rerack the Spent Fuel Pool to increase storage capacity to 3137 assemblies.
9.
Zion Station will lose full core discharge capability (for both units) in May 1993, at the end of Unit 2 Cycle 13, based on the latest Nuclear Stations Refueling Schedule.
Full core discharge capability for a single core will be lost in November, 1994, at the end of Unit 2 Cycle 14.
