SUMMARY

OF OPERATING EXPERIENCE November 1989 l Unit 1 began the month in a maintenance shutdown pending NRC agreement with_the  ;

pressurizer heater leakage analysis presented to NRC Staff on September 25.

- This analysis stated that the material defects in Unit 2 pressurizer were applicable to Unit 1 pressurizer, but Unit 1 could be safely operated.

After assessments of test results on the instrument air systems showed some potential-inadequacies, we have revised the start-up date to February 7, 1990.  ;

December 4, 1989 REFUELING INFORMATION REQUEST

1. Name of facility: Ca3 vert Cliffs Nuclear Power Plant, Unit No. 1.

2. Scheduled date for next refueling shutdown: March 15, 1991  ;

3. Scheduled date for restart following refueling: May 26, 1991

4. Will refueling or resumption of operation thereafter require a Technical Specification change or other license amendment?

Resumption of operation after refueling will require changes to Technical specifications. The changes will be such as to '

allow. operation of the plant with a higher enriched (4.3%)

reload batch and reshuffled core for Unit l's next 24 month ,

cycle, i

5. Scheduled date(s) for submitting proposed licensing action and supporting information.

November 1, 1990 ( reload submittal )

6. Important licensing considerations associated with the re-fueling.

Reload fuel will be similar to reload fuel inserted into the previous cycle except for the higher enrichment ( 4.3% ) .

7. The number of fuel assemblies (a) in the core and (b) in the '

spent fuel storage pool.

(a) 217 (b) 1543 u

Spent fuel pools are common to Units 1 and 2.

8. (a) The present licensed spent fuel pool storage capacity, and (b) the size of any increase in licensed storage capacity that has been requested or is planned, in number of fuel assemblies.

(a) 1830 (b) 2880 I

9. - The projected date of the last refueling that can be dis-charged to the Spent Fuel Pool assuming the present licensed capacity and maintaining space for one full core off-load.
