1.

Name of facility: Arkansas Nuclear One - Unit 1 2.

Scheduled date for next refueling shutdown. September 1988 l

3.

Scheduled date for restart following refueling.

November 1988 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 there be? If answer is no, has the reload fuel design and core configuration been 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)?

)

Unknown at this time. Cycle design has not been finalized.

5.

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

If necessary, May 1988.

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.

Zircaloy spacer c rids, reconstitutable upper end fitting, gray axial power shaping roc assemblies, and "retainerless" assembly design.

7.

The number of fuel assemblies (a) in the core and (b) in the spent fuel storage pool, a) 177 b)448 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 l

planned, in number of fuel assemblies, present 968 increase size by 0 9.

The projected date of the last refueling that can be discharged to the spent fuel pool assuming the present licensed capacity.
