r REFUELING INFORMATION REQUEST 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.

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.

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 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.

2. January 30, 1985 the Unit shutdown for scheduled refueling outage.

3. June 14, 1985 is the scheduled month for initial criticality following refueling.

4. Yes, a new LOCA analysis is necessary as a result of the RCFC replacement.

The old analysis bounds the results of the new analysis which has been submitted for NRC approval.

5. The new LOCA was submitted for approval February 14, 1985, but a Westinghouse model problem was found March 28, 1985. Revised results to the LOCA analysis will be submitted by April 17, 1985.

6. None

7. The number of fuel assemblies a) in the core is 193, and b) in the spent fuel storage pool which have been discharged by Zion Unit 1 is 497.

8. The present 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,1983 study.

Unit 2 - Answers

1. Zion Unit 2

2. The Unit is currently scheduled to shutdown September 6, 1985 for its next refueling outage.

3. January 10, 1986 is the scheduled date for startup after refueling.

4. The September 1985 outage will be a ten year ISI outage. Other major jobs will be turbine changeout, and RCFC replacement. Necessary Tech Spec changes and licensing amendments are being investigated.

5. Being investigated.

6. See 4 and 5.

7. The number of fuel assemblies a) in the core is 193, and b) in the spent fuel storage pool which have been discharged by Zion Unit 2 is 435.

8. The present licensed spent fuel pool storage capacity (shared with Zion Unit 1) 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, 1983 study.
