2.

Scheduled date for next refueling shutdown:

August 1986 3.

Schedule date for restart following refueling: October 1986 4.

Will refueling or resumption of operation thereafter require a technical specification change or other license amendment?

Unknown at this time.

5.

Scheduled date(s) for submitting licensing action and supporting information:

A.

Technical support information for reracking the spent fuel pool was submitted on July 24, 1985 to support a proposed license amendment.

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 operating procedures:

None 7.

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

(a) In Core:

217 (b) 449 8.

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

i Currently 667 Plans are being formulated to rerack the spent fuel pool beginning in December 1985, to incredse the storage capacity to 1106 fuel assemblies.

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.
