SUMMARY

OF OPERATING EXPERIENCE UNIT 1 The Unit entered the reporting period shutdown for the continuation of the Cycle V-VI scheduled refueling.

UNIT 2 The Unit entered the reporting period at a power level of' 940 MWe (92% reactor power).

On March 5th at 1533 l

hours a reactor / turbine trip occurred from 2C steam l

generator low-low level due to a 2B feedwater pump trip.

At 2006 hours0.0232 days <br />0.557 hours <br />0.00332 weeks <br />7.63283e-4 months <br /> the Unit was made critical and on March 6th at 0245 hours0.00284 days <br />0.0681 hours <br />4.050926e-4 weeks <br />9.32225e-5 months <br /> was synchronized to the grid.

On March lith at 0813 hours0.00941 days <br />0.226 hours <br />0.00134 weeks <br />3.093465e-4 months <br /> a reactor / turbine trip occurred from a contractor cutting through a cable causing loss of feedwater pumps resulting in low-low level trip in "C"

steam generator.

The Unit was made critical at 1320 hours0.0153 days <br />0.367 hours <br />0.00218 weeks <br />5.0226e-4 months <br /> and at 1909 hours0.0221 days <br />0.53 hours <br />0.00316 weeks <br />7.263745e-4 months <br /> was synchronized to the grid.

The Unit remained on-line the remainder of the reporting period having an Availability Factor of 97.0% and a Capacity Factor of 82.9.

The Unit ended the month on-line at a power level of 940 MWe (91% Reactor Power).

Page 1 of 3 REFUELING INFORM /sTION 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 I

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.

January 15, 1981, was the starting date for the refuel-ing outage.

3.

April 13, 198L is the scheduled date for initial criticality following refueling.

4.

The reload fuel design and core configuration has undergone On-Site Review.

There are no unreviewed safety questions or Tech. Spec'. changes, therefore, the reload will be done under a 50.59 submittal.

The Off-Site Review is completed.

5.

If the need for Technical Specification changes or other license amendments arise from the review in 4 above, then November 1,1980, will be the schedul-ed date for submitting the required information.

7.

The number of fuel assemblies a) in the core is 193, and b) in the spent fuel storage pool, which have been discharged from Zion Unit 1, is 308~.

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 is presently oc-curring.

9.

October, 1992, is the projected date of the last Zion Unit 1 refueling which can be discharged to the spent fuel pool assuming the present licensed capacity.

Zion Unit 2 2.

September 13, 1981,is the scheduled date for the next refueling outage.

November 8, 1981,is the scheduled date for initial criticality following refueling.

4.

The reload fuel design and core configuration has not undergone On-Site and Off-Site Review.

However, no Technical Specification changes or license amendments are anticipated.

The On-Site and Off-Site review of the Cycle VI fuel design and core configuration is currently scheduled for completion by July 15, 1981.

5.

If the need for Technical Specification changes or other license amendments arise from the review in 4 above, then August 1, 1981,will be the scheduled date for submitting the required information.
