SUMMARY

OF OPERATING EXPERIENCE J

!) NIT 1 Unit 1 began September off-line because of a continuation of repairs on the pressurizer PORV block valve (valve had stalled and lost indication).

On September 18,1996 at 0138 hours0.0016 days <br />0.0383 hours <br />2.281746e-4 weeks <br />5.2509e-5 months <br /> Unit I was back on line and remained on-line for the remainder of the repcrting period. Unit 1 concluded the reporting period at 1080 MWe power level (99.9% reactor power) and with an availability factor of 43.1% for the month of September.

UNIT 2 I

Unit 2 began September on-line at 1084 MWe power level (100% reactor power).

l i- Unit 2 was taken off-line at 0032 on September 19. 1996 for a refueling outage (Z2R14) which is scheduled to last for 58 days.

REFUELING INFORMATION RE0 VEST 00ESTIONS:

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. x neduled 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.

REFUELING INFORMATION REQUEST UNIT 1 - ANSWERS:

1. Zion Unit 1.

2. Cycle 15 is scheduled to shutdown April 5, 1997 for refueling.

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.

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.

5. Projected submittal of License Amendment is the last half of November,1996.

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. 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 than 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 (M22-90-0-008A, C) will be installed prior to June 2003. This projected date is subject to change based on outage durations or Overhaul Schedule changes.

REFUELING INFORMATION REQUEST UNIT 2 - ANSWERS:

1. Zion Unit 2.

2. Cycle 14 is scheduled to shutdown September 19. 1996 for refueling.

3. Cycle 15 is scheduled to start up November 16, 1996.

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

e Appendix J option B - sent to NRC.

• F* - sent to NRC.

• CE Sleeving - Amendment sent to NRC.

5. The following outstanding proposed License Amendments are required for startup from Z2R14.

e Appendix J option B - allows elimination of ILRT. Initial submittal was August 29, 1996. Submittal was revised October 4 1996 and September 20. 1996.

e F* - Required for Steam Generator re-roll work planned for outage.

Initial submittal was August 16, 1996. Submittal was supplemented October 4. 1996.

e CE Sleeving - Required to support revised methodology to be used in outage. Initial submittal was September 3. 1996.

e Reload and Core Operating Limits Report (COLR) scheduled for On Site Review September 18. 1996.

6. New fuel to be reloaded into Unit 2 Cycle 15 core will incorporate the following design changes:

e Selected standard Integral Fuel Burnable Absorber (IFBA) patterns have l been updated following a West 1nghouse Core Engineering investigation of peripheral IFBA rod loading within the fuel assembly. The net effect of this change is to achieve the most efficierit absorber orientation at Beginning of Life (BOL) and for burnups through 5000 i MWD /MTV. These patterns provide self-limiting features that mitigate j the extent of DNB propagation. In addition. these IFBA patterns provide significant peaking factor and reactivity holddown benefits.

I i

3 of 4 ZCLERK-13

REFUELING INFORMATION REQUEST UNIT 2 - ANSWERS- (Continued) e IFBA rods will have a nominal B-10 enrichment loading with a reduction 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 internal pressure and clad stress criteria. The Zion Unit 2 Cycle 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 0 (Unit 2 is shutdown for refueling, and Core offload was completed 10/5/96).

(b) in the spent fuel storage pool from Zion Unit 2 is 1177 (193 assemblies offloadcd from Unit 2 core, plus 76 new fuel assemblies to be reloaded into core, plus previous 908 Unit 2 assemblies residing in the spent fuel pool).

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 (M22-90-0-008A, C) will be installed prior to June 2003. This projected date is subject to change based on outage durations or Overhaul Schedule changes.
