2. Scheduled date for next refueling shutdown: July 30.1993 Currently in Refuel Outage

3. Scheduled date for restan following refueling: September 291993

4. Will refueling or resumption of operation thereafler require a technical specification  ;

change or other license amendments?  ;

e Y_es l 5. Scheduled date for submitting licensing action and supporting information.

l I

Submitted March 15.1993 & Julv 30.1993 l 6. Imponant licensing considerations associated with refueling, e.g., new or different fuel design or supplier, unreviewed design of performance analysis methods, significant changes in fuel design, new operating procedures:

Millstone Unit 3 current fuel design incorocrates a stainless steel skeleton and zircaloy .

fuel cladding desien. Cycle 5 feed assemblies will utilize zirlo fuel rod cladding:

selected assemblies will incorporate a zirlo skeleton. A Technical Specification change was submitted as ner cuestion 5 above. In addition. a Technical Specification change to increase the reauired boric acid volume in the Boric Acid Storage Tank was submitted on July 30.1993.

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

(a): 0 (b): 525

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 size - 756.

No increase reauestei

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

End of cycle 5.  ;
