REFUELING INFORMATION REQUEST i

OUESTIONS:

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 l unreviewed safety questions are associated with the core reload (Ref. 10 t CFR Section 50.59)? ,

If no such review has taken place, when is it scheduled?

i

5. Scheduled.date(s) for submitting proposed licensing action and supporting. i information.  ;

6. Important licensing considerations associated with refueling, e.g.. new i or different fuel design or supplie.. 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 the 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. ,

REFUELING INFORMATION REQUEST UNIT 1 - ANSWERS:

1. Zion Unit 1.

2. Cycle 14 is scheduled to shutdown September ,, 1995 for refueling.

3. Cycle 15 is scheduled to start up November 4.1995.

4. No. There are no outstanding License Amendments required to allow resumption of operation after Refueling Outage Z1R14. However, there are two proposed License Amendments being prepared which will allow installation of modifications during the outage. The first License Amendment will revise the Secondary Undervoltage setpoint.s based on new engineering calculations. The second License Amendment will extend the Reserve Source of Off-Site AC Power Allowed Outage Time (A0T), on a one time basis, to allow installation of a System Auxiliary Transformer

, modification on Unit 1. A third proposed License Amendment in preparation will allow storage of fuel enriched to up to 4.65 weight percent U-235, in the New Fuel Storage Vault (NFSV), prior to.Z1R14. If this amendment is not received before new fuel receipt, new fuel will be transferred directly into the Spent Fuel Pit for storage.

The Reload Safety Analysis has not been completed. Initial review of the Reload will be completed in November. Final approval is scheduled to be completed by January 31, 1995.

5. The Reserve Source A0T Extension and NFSV License Amendment Requests are scheduled to be submitted in early October. The Secondary Undervoltage I License Amendment Request is scheduled to be submitted in late October.

6. Not applicable.

7. The number of fuel assemblies 1

(a) in the core is 193, and (b) in the spent fuel storage pool from Zion Unit 1 is 860. l

8. The present licensed spent fuel pool storage capacity (shared with Zion Unit 2) is 3012 fuel assemblies (only 2762 locations will be accessible).

9. Zion Station will lose dual full core discharge capability in November 2001. at the beginning cf Unit 1 Cycle 19, based on the latest Nuclear Stations Refreling Schedule. Full core discharge capability for a single core will be lost in May 2003 at the beginning of Unit 1 Cycle 20.

These projections are based on the current number of available storage cells in the spent fuel pool and does not include the use of the offset tool.

REFUELING INFORMATION REQUEST UNIT 2 - ANSWERS:

1. Zion Unit 2.

2. Cycle 13 is scheduled to shutdown January 5. 1995 for refueling.

3. Cycle 14 is scheduled to start up March 22, 1995.

4. Yes, A License Amendment was required to allow resumption of operation after Refueling Outage Z2R13. The NIS Instrumentation License Amendment was approved by the NRC on 10/14/93 (License Amendment 149/137). This amendment will allow startup after Z2R13, during which new Source and Intermediate Range NIS detectors will be installed.

5. There are no outstanding proposed License Amendments required for startup from 22R13. This item is not applicable.

6. Not applicable.

7. The number of fuel assemblies (a) in the core is 193, and '

(b) in the spent fuel storage pool from Zion Unit 2 is 024.

8. The present licensed spent fuel pool storage capacity (shared with Zion Unit 1) is 3012 fuel assemblies (only 2762 locations will be accessible)  ;

9. Zion Station will-lose dual full core discharge capability in November 2001, at the beginning of Unit 1 Cycle 19, based on the latest Nuclear Stations Refueling Schedule. Full core discharge capability for a single core will be lost in May 2003, at the beginning of Unit : Cycle 20. ,

These projections are based on the current number of available storage '

r lls in the spent fuel pool and does not include the use of the offset tool. ,
