3 REFUELING INFORMATION Date:
June 1988 1.
Nan:e of facility:
Davis-Besse Unit 1 2.
Scheduled date for next refueling outage? Tentative Outage Vindov October 1989 3.
Scheduled date for restart from current refueling:
September 1988 4.
Vill refueling or resumption of operation thereafter require a technical specification change or other license amendment? If answer is yes, what in general vill these be? If answer is no, has the reload fuel design and core configuration been reviewed by your Plant
.2fety Review Committee to determine whether any unreviewed safety questions are associated with the core reload (Ref. 10 CFR Section 50.59)?
Ans: The Reload Report requires standard reload fuel design Technical Specifications changes (2. Safety Limits and Limiting Safety System Settings, 3/4.1 Reactivity Control Systems, 3/4.2 Power Distributiun Limits and 3/4.4 Reactor Coolant System.)
