OPERATIONAL

SUMMARY

August, 1983 The unit cutage, which began on July 25, 1983, was still in progress <

through the end of August, 1983.

The following are the more significant outage activities performed during this month:

1) The inspection of upper core barrel bolts was completed, and no defective bolts were found.

2) Fuel shuffle was successfully completed.

3) Steam generator eddy current testing was completed with no problems noted.

4) Condenser tube eddy current testing was completed.

5) Circulating water pumps inspection was completed. During that inspection minor impeller damage on two of the four pumps was discovered. They were shipped to the vendor for inspection and repair.

6) Snubber testing was completed. A total o," thirty snubbers were functionally tested.

7) Fuel assembly holddown springs inspection was completed. One broken spring was found in an assembly that is not scheduled to go back in the core.

1. Name of facility: Davis-Besse Unit 1

2. Scheduled date for next refueling shutdown: July 25, 1983

3. Scheduled date for restart following refueling: September 20, 1983

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)?

Ans: Expect the Reload Report to require standard reload fuel design Technical Specification changes (3/4.1 Reactivity Control Systems and 3/4.2 Power Distribution Limits).

5. Scheduled date(s) for submitting proposed licensing action and supporting information: July, 1983

6. Important licensing considerations associated with refueling, e.g.,

new or different fuel design or supplier, unreviewed design or performance analysis methods, significant changea in fuel design, new operating procedures.

) Ans: None identified to date.

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

(a) 177 (b) 140 - Spent Fuel Assemblies

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: 735 Increase size by: 0 (zero)

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

Date: 1993 - assuming ability to unload the entire core into the spent fuel pool is maintained.
