l j)_NTT2 )

Unit 2 began January on-line at 501 MWe power level (49% reactor power).

l Unit 2 had been at less than 50% power to prepare to isolate the condenser northeast waterbox since December 27, 1995, On January 13,1996 at 0200 the reacts r was manually tripped for scheduled outage Z2P04 for repairs on the Main Condenser tube leaks.

Unit 2 remained off-line for the rest of the reporting per,iod and had a 39%

REFUEL!NG INFORMATION REQUEST

. 0UESTIONS:

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 uestions are associated with the core reload (Ref. 10 CFR Section 50,59) l If no such review has taken place, when is it scheduled?

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

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

or different fuel design or supplier, unreviewed design or performance i analysis methods, significant changes in fuel design, new operating i procedures. J l

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

8. The present licensed spent fuel pool storage capacity and the size of any 1 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.

UNIT 1 - ANSWERS:

1. Zion Unit 1.

2. Cycle 15 is scheduled to shutdown March 8, 1997 for refueling.

3. Cycle 16 is scheduled to start up April 25, 1997.

4. No, there are no identified License Amendments required to allow resumption of operation after Refueling Outage Z1R15.

The Reload Safety Analysis for cycle 16 will be completed during Z1R15.

5, 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 1 is 932.

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 December 2001, at the beginning of Unit 1 Cycle 19, based on the latest Nuclear Stations Refueling Schedule. Full core discharge capability for a single i 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.
