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

2. Scheduled date for next refueling shutdown. 10-01-1980

                                                                                .

3. Scheduled date for restart following refueling. 12-01-1980

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 these be? If snswer is no, has the reload fuel design and core configuration been reviewed by your Plant Safety Review Committee to determine uhether any unreviewed safety questions are associated with the core reload (Ref. 10 CFR Section 50.59)? Yes, Reload Report and associated proposed 'echnical Specification Changes.

5. Scheduled date(s) for submitting proposed licensing action and supporting information. 08-01-1980

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. Will reload 72 fresh fuel assemblies and operate for approximately 16 months.

7. The number of fuel assemblies (a) in the core and (b) in the spent fuel storage pool. a) 177 b) 176

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 590 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.

4 NRC MONTHLY OPERATING REPORT

'

OPERATING

SUMMARY

- JUNE, 1979 UNIT I The unit was in a heatup condition until 6/2, when the NRC ordered the unit shutdown due to Emergency Feedwater System operating procedure questions. Operations was conducting a surveillance test to prove the operability of the Main Feedwater Check Valves. The Emergency Feedwater pump actuation was defeated to preclude an undesirable auto start. This conditien was not authorized by the controlling procedure, nor was it allowed by the Technical Specifications. Operating procedures were modified accordingly.

Heatup of the unit resumed, following NRC approval, cn 6/14. The plant heatup process continued until 6/19, when the NRC requested a delay until they could inquire about several items that the resident NRC inspector had observed and reported during the heatop evolution. The unit was returned to Hot Shutdown conditions. After a delay of approximately eight hours, the NRC concerns were successfully resolved and the unit startup was resumed. The reactor was declared critical on 6/20 and the Zero Power Physics Testing was begun. Testing was completed and the unit placed on line on 6/24. Physics Testing at the 40% rated reactor power level was completed on 6/28. Testing at the 75% power level continued through-out the month.

                                                                     -
