SUMMARY

JANUARY 1990 UNIT TWO The unit began the month off line for the repair of a loose connection in a feedwater control cabinet.

On the seventh, at 0021 hours2.430556e-4 days <br />0.00583 hours <br />3.472222e-5 weeks <br />7.9905e-6 months <br />, the unit was placed on line; and power was

!- increased with some hold points for normal unit startup. On the tenth, at 1015 hours0.0117 days <br />0.282 hours <br />0.00168 weeks <br />3.862075e-4 months <br />, the power escalation was stopped at 90% due to a condenser tube leak. Following the repair _of the condenser tube leak, the unit remained at 90% power due to radwaste fan and feedwater control problems. After resolving the radwaste and feedwater problems, the unit attained 100% full power on the seventeenth at 0716 hours0.00829 days <br />0.199 hours <br />0.00118 weeks <br />2.72438e-4 months <br />.

DATE: January. 1990 I REFUELING INFORMATION l'

1. Name of facility: Arkansas Nuclear One - Unit 2

2. Scheduled date for next refueling shutdown. February 1991 (Beginning of Cycle 8 criticality was 11/18/89)

3. Scheduled date for restart following refueling. April 1991  ;

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 there be? If answer is no, has the r 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)? r None Expected. Reload fuel design is in progress. ,

I

5. Scheduled date(s) for submitting proposed licensing action and supporting information. None Required

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.

To obtain the presently planned cycle 8 length of 420 EFPD. it will be necessary to raise the current peak rod burnup limits. A report justifying an increase was submitted in July. 1989.

7. The number of fuel assemblies (a) in the core and (b) in the spent fuel storage pool, a) 177 b) 421

8. The 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 988 increase size by 0

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