1 NRC MONTHLY OPERATING REPORT-OPERATING SUMMAR - MARCH, 1982 UNIT I Unit One began the month of March at 83.21% full power. The unit was in a power limited condition due to fouling of the "A" Steam Ger.erator.

Operations at reduced power have been required to prevent flooding of the "A" 0TSG feedwater nozzles. On March 17, high . seal bleedoff temperature on the "D" reactor coolant pump prompted shutdown of the pump. At 1307 with the reactor at 62% full power, "D" RCP was secured. Power was later -increased to approximately 72% where it remained until March 26. On March 26, Unit One was brought to cold shutdown to replace the "A" 0TSG feedwater nozzles. Unit One remained in cold shutdown through the end of the month.

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

2. Scheduled date for next refueling shutdown. 12/1/82

3. Scheduled date for restart following refueling. 2/15/82

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 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)?

Yes. Reload report and associated proposed Specification changes.

5. Scheduled date(s) for submitting proposed licensing action and supporting information. 9/1/82

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. Four of which will be high burn-up test assemblies.

7. The number of fuel assemblies (a) in the core and (b) in the spent fuel storage pool, a) 177 b) 244

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 assemblics.

present 589 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.

DATE: 1986
