Questions  ;

1. Name of f acility.

2. Scheduled date for next refueling shutdown.

l t

3. Scheduled date for restart following refueling. [

4. Will refueling or resumption of operation thereafter require a [

technical specification change or other license weendment? r If answer is yes, what, in general, will these be? ,

If answer is no, has the reload fuel des'.gn and core configuration been reviewed by your Plant Safety Review Committee to determine

• whether any unreviewed safety questions are associated with the core i reload (Ref. 10 CTR Section SC.59)?

i If no such review hcs taken place, when is it scheduled? l l

5. Scheduled date (s) for submitting proposed licensing action and [

supporting information. i f

6. Important licensing considerations associated with refueling, e.g.,

new or different fuel dtsign or supplier, unreviewed design or performance analysis methods, significant changes in fuel design, new operating procodures.

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

i l W. The present licensed spent fuel pool storage capacity and the sise of f any increase in licensed storage capacity that has been requested or I l

La planned, in number of fuel assemblies. i l

l f 9.

The projected date of the last refueling that can be discharged to the spent fuel pool assuming tne present If eensed capacity.

1. Zion Unit 1

2. Next refueling outage is currently scheduled to begin on August 24, 1989.

3. The initial criticality following refuelin/ is scheduled for November, 1989.

4. No required Technical Specification changes have been identified for the next cycle. However, two Technical Specification change requests are being considered. The first will result from a new LOCA analysis being pershed that vill allow steam generator tube plugging levels of greater than 10%. The second would allow for new methods of steam generator repair (tube sleeving). The reload safety twview is planned for May 1989. The On-sate Review will be held after that review.

5. Note

6. None

7. The number of fust assemblies a) in the core is 193, and b) in the spent fuel Storage pool from Zion Unit 1 is 632. Four of the recently discharged 80 assemblies were originally Zion Unit 2 assemblies.

8. The pr9sent licensed spent fuel pool storage capacity (shared with Zion Unit 2) is 2112 fuel assemblies. The installation of the new storage racks has been completed.

9. In 1995, Zion Station will lose full core discharge capability. This date is based on a December, 1987 study, Page 2 of 3 1397t
