4. Will refueling or resumption of operation thereafter re' quire' a technical specification change or other license acendment? , 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 sefety 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 grids, reconstitutable upper end fitting, gray axial power shaping rod 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 planned, in number of fuel assemblies present 968 increase size by 0

9. The projected date of the last refueling that can be dischar3ed to the spent fuel pool assuming the present licensed capacity.

DATE: 1997 (Loss of fullcore offload capability)
