DATE:

February, 1986 REFUELING INFORMATION 1.

Name of facility:

Arkansas Nuclear One - Unit 2 2.

Scheduled date for next refueling shutdown.

Cycle 5 was initiated in May 1985.

The next refueling shutdown is scheduled for June 1986.

3.

Scheduled date for restart following refueling.

August 1986 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)?

Yes.

Two technical specification changes on shutdown boron concentration and moderator temperature coefficient are in preparation 5.

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

April, 1986.

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.

The fresh fuel will have a modification to the CEA guide tube wear sleeves which has been reviewed.

(Ref. SER dated September 7, 1984 for C-E Report LD-84-043). A longer cycle and a thange in in-core fuel management from out-in-in to in-in-out are also planned.

When pending Technical Specification changes are approved, we expect to install a revised CPC program during Cycle S.

7.

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

a) 177 b) 229 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.

present 988 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.
