SUMMARY

FEBRUARY 1998 UNIT ONE The unit began the month of February operating at 100% power.

At 2100 hours0.0243 days <br />0.583 hours <br />0.00347 weeks <br />7.9905e-4 months <br /> on the thirteenth, a power reduction to 85% was commenced for main turbine governor valve testing. Following the completion of the turbine test, the unit was returned to 100% power at 0000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> on the founeenth. The unit operated the remainder of the month at 100% power.

There were no challenges to the primary system code safeties nor automatic actuations of the electromatic relief valve during this reporting period.

4 Reporting Period: February 1998 REFUELING INFORMATION

1. Nave of facility: Arkansas Nuclear One - Unit 1
2. Scheduled date for next refueling shutdown March 28.1998
3. Scheduled date for restart following refueling: May 10.1998 4 Will refueling or is..,,;;on of operation thereaAct require a technical specification change or other license amendment? If answer is yes, what, in general, will there be? If answer is no, has the reload fuel design and core configuration been reviewed by your Plant Safety Review Comnuttee to determine whether any unreviewed safety questions are associated with the core reload (Ref.10CFR Section 50.59)?

No.No

5. Scheduled date(s) for submitting proposed licensing action and supportmg information-N!A
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.

Nonc planned

7. The number of fuel assemblics (a) in the core, (b) in the spent fuel storage pool and (c) dry cask storage:

a) 11Z b)23 c) 48

8. 'Ihe 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 number of fuel assemblies:

present 26L8 increase size by 0

9. 'Ihc projected date of the last refueling that can be discharged to the spent fuel pool assuming the presentlicensed capacity:

Full core off-land canability was reemi-I on 3/10/98 by ram *ina miscellaneous materials stored in the spent fuel nool. This canability will be lost amain followma the refuelina outane with the discharac of the depleted assemblics.
