7 REFUELING INFORMATION REQUEST 1 OVESTIONS:

.1. Name of facility.

2. Scheduled 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?

If a"swer is yes, what, in general, will these be?

If unswer 1s- 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)?

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

J l S. Scheduled Jate(s) for submitting proposed licensing action and supporting information.

6. Important licensing considerations associated with refueling, e.g., new or l- different fuel design or supplier, unreviewed design or performance analysis
methods, significant changes in fuel design, new operating procedures. l l  !

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

storage pool. 1 l 8. .The present licensed spent fuel pool storage capacity and the size of any l increase in licensed storage capacity that has been requested or is planned,

! in the number c,f fuel assemblies. 'l

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