REIVEl.ING IlfEORMAIIO!LREQUESI Queitions:

1. Name of facility.

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, then 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 Itcensed 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.

9. The projected date of the last refueling that can be discharged to the spent fuel pool assuming the present licensed capacity.

5. Not appilcable or none proposed.

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 784.

8. The present licensed spent fuel pool storage capacity (shared with Zion Unit 2) is 2112 fuel assemblies. Plans are being developed to rerack the Spent Fuel Pool to increase storage capacity to 3012 assemblies. j i

9. Zion Station will lose dual full core discharge capability in February 1994, at the beginning of Unit 1 Cycle 14, based on the latest Nuclear Stations Refueling Schedule. Full core discharge capability for a single core will be lost in February 1996, at the beginning of Unit 2 Cycle 15.

2. Cycle 12 was Shutdown 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 Z2C13, 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,

6. License considerations atsectated with the Z2C13 reload include the new VANTAGE fuel design, and the new LOCA analysis with higher core power peaking factors required for the low-low-leakage loading pattern used in 22C13.

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 840,

8. The present licensed spent fuel pool storage capacity (shared with Zion Unit 1) is 2112 fuel assemblies. Plans are being developed to rerack the Spent Fuel Pool to increase storage capacity to 3012 assemblies.

9. Zion Station will lose dual full core discharge capability in February 1994, at the beginning of Unit 1 Cycle 14, based on the latest Nuclear Stations Refueling Schedule. Full core discharge capability for a single core will be lost in February 1996, at the beginning of Unit 2 Cycle 15.

4 4 ADDENDUM TO ZION STATION HONTHLY REPORT Special Report submitted in accordance with Zion Tech Spec. Sury. 4.15.1.B.5 This report addresses one valid failure of the 0 EDG. The criteria to determine valid tests is in accordance with section C.2.e of Reg. Guide 1.108.

On January 10, 1993 the IA EDG was declared inoperable due to a high concentration of water in the lube oil. Investigation revealed that jacket water was entering the lube oli through a cylinder head stud hole. The cylinder head was replaced and the EDG was declared operable following the successful performance of PT-11. As of January 31, 1993 this was the 6th valid railure in the last 100 valid unit demands for Unit 1. This failure was determined to be valid per Reg. Guide 1.108 C.2.e.

The tett frequency for IA EDG changed to 7 days.
