-'The unit" entered the rep d ting period at~1064 MWe (99% reactor power).

The unit remained on line the entird month ending at a power level of 1080

?.). - MWe (99% reactor-power), hav ing aniavailability f actor of.100%.

(

' UNIT 2.

The: unit ~ entered the; reporting period at.1092 MWe (99% reactor power), On

't October.2nd at-0156 hours,'the unit was taken off~line due to excessive 5

packing leakage.on the pressurizer spray salves.. On October 5th at 2055 3

' hours the reactoh was made critical and 'on' October 6th at 0840 f ours, the-

unit.was synchronized.to'the grid.

The unit. remained on;11Ge the remainder of the reporting period, ending atia power level of-1087 MWe

. (99% reactor power) and havirg an avaliability factor of 86.2%.

If: answer Lis yes,- what,-in genera l, wili z these be?.

1 Lif. answer is'.'no, has the re' loads fuelsdehign and core configuration f

been~ reviewed by',y'our Plant Safety. Review. Committee to determine whether any unreyevedesafety ~questiow are ' associated-with the core reload (Ref. 10 CFR Section 50.59)?

If no such review;has taken place, when is it scheduled?.

i 5.

Scheduled date'(s) for' submitting proposed licensing action and supporting information-.

6.

Important licensing considerations associated with refueling, e.g.,

new or dif ferent-(uel de'sigii or supplier, unreviewed design or performance analysis methods, significant changes in fuel design, new operating procedures.

7.

'The number of fuel' assemblies (a) in the core and. (b) in the spent Lfuel storage pool.

8...The present licensed spent fuel pool storage' capacity'and the size of any increase,in licensed. storage capacity'that has been re' quested or is planned, in ntimber of fuel assemblies.

February 25, 1988 is th'e currently scheduled shutdown date.

3.

Based.on the above shutdown, the initial criticality fo'llowing refueling

(-

-would occur'early-May,1988.

4.

No required Technicai Specification changes have been identified for the next cycle. There is a concern on the extent of Steam Generator tube plugging in Steam Generator "B" that may occur during the next outage.

Using sleeving as a method.of Steam Generator repair, the ef fective total plugging should remain below 10%. The reload safety review was held in y'

October,1987 and no unreviewed safety questions were identified for the proposed reload.

The On-Site Review will he held before start-up.

None-

l.

The number of fuel assemblies

, a) in the core it 193, and b) in the spent fuel storage pool f rom Zion Unit 1 is 556.

8.

The present'ikensed spent fuel pool storage capacity (shared with Zion Unit 2) is 2112 fuel assemblies. The installation of the new storage racks has been completed.

9. l10.1995,- Zion Station'will lose full core discharge capability.

This date is based'or a December, 1986 study.
