1. Name of facii' ty.

2. Scheduled date for next refueling shutdown.

3. Scheduled date for restart following refueling.

4. Hill 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 fue'l 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 Ilcensed spent fuel. pool storage capacity and the size of any increase in licensed storage capacity that has been requested or_-

is planned, in number of fuel assemblies.. s

9. the projected date of the last refueling that can be dischargedLto-the spent fuel pool assuming the present licensed capacity.

2. Cycle 12 was November 12, 1992 for refueling.

3. Cycle 13 is scheduled to start up February 20, 1993.

4. Yes. Technical _ Specification changes have been made to include the-Hestinghouse VANTAGE fuel design being. loaded for 22C13, and effects of the vessel fluency reduction program beginning with Z2C13.

A Tech Spec change has also been made that will allow CECO to use a CORE OPERATING LIMITS REPORT (COLR) in-place of some existing Tech-Spec Limits.

5 License amendments for the Z2C13 reload were submitted in Summer.

1991, and were approved July 26, 1992 Amendment 128,

-.i ADDENDUM TO ZION STATION MONTHLY REPORT-Special Report submitted in accordance with Zion Tech Spec. Surv. 4.14.B. 5-This report' addresses two invalid failures of the 0 EDG. The. criteria to determine valid tests and failures is in accordance with section C. 2.e of Reg. Guide 1.108.

On November. 20, 1992 the 0 EDG tripped during a maintenance run for-maintenance verification. .The-engine had been Out Of Service (O. O. S.), for preventative maintenance (including the replacement of 4 cylinders), for approximately six days. The engine was started, in the maintenance mode and tripped prior to reaching rated speed. It is currently believed that this trip was caused by the work performed. The EDG was returned to service on November 22, 1992 following the successful completion of PT-II. This failure was determined to be invalid per Reg.' Guide 1.108 C. 2.e.

On November 20, 1992-the O EDG was secured, during a maintenance'run, in response to an unusual noise near the 2L cylinder. Investigation revealed.an improperly installed fuel cam key for the 2L cylinder. The key had been improperly installed during the maintenance immediately preceding this?run.

The EDG was returned to service, following the repositioning of the fuel cam key, on November 22, 1992 following the successful completion of PT-11. This

-fallure was determined to be invalid per Reg. Guide 1.108 C. 2.e.

As of November 30, 1992 the test frequency for 0 EDG remains at 31 days.
