1.

Name of facility.

2.

Scheduied date for next refueling shutdown.

3.. Scheduled date-for restart following refueling.

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

i If answer is yes, what, in general, will these 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) ?

i i

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

5.

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

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.

7.

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

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.
