begin on February 16L1985.-

'3. -Schedulei d ate for. restart following refueling:-June 1985-4.' Will~ refueling or resumption of operation thereafter require a.-technical specification change or other_. license amendment?

! .The discharge of failed fuel may r'equire additional technical specification E -

changes ~and a new-reload safety evaluation forlthe revised-core loadingl pattern.

l '5. Scheduled date(s) for submitting licensing action and -

supporting information

a)'A. technical . specification cha'nge request has' been submitted for the Outage Equipment Hatch. -

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

new or different fuel' design'or supplier, unreviewed design or t performance analysis methods,-sigr.ificant chinges in fuel design,

new operating procedures

The _ discharge of failed fuel may require additional technical specification changes and will impact the reload safety evaluation.

7. The number of fuel assemblies (a) in the core and'(b) in the spent i

fuel storage pool:

8. The present licensed spent' fuel pool storage: capacity and the size l of any increase in licensed storage capacity that has been requested or is. planned, in number of fuel-_ assemblies:

Currently 667 Plans are being formulated to rerack the spent fuel' pool beginning

[.

in July 1985, to increase the storage capacity to 1106 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:

1985, Spent Fuel Pool, Full ~ core.off load capacity is reached.

1987, Core Full,-Spent Fuel Pool _contains 648 bundles.
