SUMMARY

OF OPERATING EXPERIENCE i

l I t

i UNIT 1 i l

l Unit 1 began November on-line at 1075 MWe power level (99.4% reactor power). Unit 1 remained on line for the entire reporting period. Unit I concluded the j j reporting period at 1085 MWe power level (99.8% reactor power) and with an l availability factor of 100.0% for the month of November.  ;

UNIT 2 Unit 2 began November off-line for a continuation of refueling outage (Z2R14).

Unit 2 is scheduled to be back on-line on December 25. 1996.

l 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 i

, specification change or other license amendment?- i If answer is yes, what, in general, will these be?

l 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 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.

1. Zion Unit 1.
2. Cycle 15 is scheduled to shutdown April 5.1997 for refueling. l
3. Cycle 16 is scheduled to start up May 25, 1997.
4. The following License Amendments are required to allow resumption of operation after Refueling Outage Z1R15.

I e Increase Steam Generator plugging limit. Required to ensure Unit derating will not be required based on Steam Generator plugging.  ;

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

5. Projected submittal of License Amendment is January, 1997. j
6. Not applicable.
7. The number of fuel assemblies (3) 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. Of these 3012 storage locations. 11 are unavailable and 239 are inaccessible pending completion of the Offset Tool ,

l Modification (M22-90-0-008A. C).

l l 9. The projected date of the last refueling than can be discharged to the spent i

fuel pool, assuming the present licensed capacity of 3012 locations (11 out of 3012 are unavailable) is April 2006 (from Z1R21) based on the 1996 Projected Comed Overhaul Schedule. This assumes the Offset Tool Modification (M22-90-0-008A. C) will be installed prior to June 2003. This

, projected date is subject to change based on outage durations or Overhaul l Schedule changes.

UNIT 2 - ANSWERS:

)

l

1. Zion Unit 2.
2. Cycle 14 is scheduled to shutdown September 19, 1996 for refueling.
3. Cycle 15 1s scheduled to start up December 25, 1996.

l 4. The following outstanding License Amendment Requests are required for i l startup of Unit 2 following Refueling Outage Z2R14. l i

e PTLR Amendment - in NRC review. l

5. There are no outstanding proposed License Amendments required for startup l l from Z2R14. l l
6. New fuel reloaded into Unit 2 Cycle 15 core will incorporate the following design changes:

0 Selected standard Integral Fuel Burnable Absorber (IFBA) patterns have been updated following a Westinghouse Core Engineering investigation of peripheral IFBA rod loading within the fuel assembly. The net

effect of this change is to achieve the most efficient absorber l orientation at Beginning of Life (BOL) and for burnups through 5000 MWD /MTU. These patterns provide self-limiting features that mitigate the extent of DNB propagation. In addition, these IFBA patterns provide significant peaking factor and reactivity holddown benefits.

l e IFBA rods will have a nominal B-10 enrichment loading with a reduction l in backfill pressure from 200 to 100 psig. The nominal B-10 loading is 1.77 mg/ inch. Rod internal gas pressure has an effect on two of the fuel rod design criteria that are evaluated for the reload: Rod l internal pressure and clad stress criteria. The Zion Unit 2 Cycle l

Specific fuel design analysis has been performed and has demonstrated that the design criteria were met.

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 984.
8. The present licensed spent fuel pool storage capacity (shared with Zion Unit
2) is 3012 fuel assemblies. Of these 3012 storage locations.11 are unavailable and 239 are inaccessible pending completion of the Offset Tool Modification (M22-90-0-008A, C).
9. The projected date of the last refueling that can be discharged to the spent fuel pool, assuming the present licensed capacity of 3012 locations (11 out of 3012 are unavailable) is April 2006 (from Z1R21) based on the 1996 Projected Comed Overhaul Schedule. This assumes the Offset Tool Modification (M22-90-0-00BA C) will be installed prior to June 2003. This projected date is subject to change based on outage durations or Overhaul Schedule changes.
