OPERATIONAL

SUMMARY

Feb rua ry , 1984 The unit operated at approximately 99% of full power until 2238 hours0.0259 days <br />0.622 hours <br />0.0037 weeks <br />8.51559e-4 months <br /> on February 5, 1984, when Control Rod Group 7-7 experienced a ratchet trip to 5% withdrawn. When a runback did not occur, the reactor.was manually reduced to 60% power. Following the replacement of a fuse on Rod 7-7, reactor power was increased and returned to 90% power at 0630 hours0.00729 days <br />0.175 hours <br />0.00104 weeks <br />2.39715e-4 months <br /> on February 6,1984 and 99% power later than night.

REFUELING INFORMATION DATE: Feb ruary, 1984  !

1. Name of facility: Davis-Besse Unit 1

2. Scheduled date for next refueling shutdown: August 3, 1984

3. Scheduled date for restart following refueling: October 14, 1984

4. Will refueling or resumption of operation thereafter require a technical specification change or other license amandment? 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 theRel[adReport 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, 1984 '

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

new or different fuel design or suppliar, unreviewed design or performance analysis methods, significant changes 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.
