REFUELING INFORMATION RE0 VEST Questions:

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 answer is yes, what, in general, will these 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 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.

l

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

7. The number of fuel 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 l 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.

1. Zion Unit 1

2. Current refueling outage began February 24, 1988. Next refueling outage is currently scheduled to begin on August 31, 1989.

3. The initial criticality following refueling is scheduled for April 28, 1988.

4. A Technical Specification change has been submitted to approve the Westinghouse method of sleeving. Approval is pending. The reload safety i review was held in October,1987 and no unreviewed safety questions were identified for the proposed reload. The On-Site Review will be held i before start-up.

5. None 1

6. None

7. The number of fuel 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 present licer. sed 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.
