L If' answer is yes, what, in general, will these be?

r 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)?

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.,

R 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 fue1' 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.

9.

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