6 REFUELING INFORMATION Date:
September 1988 1.
Name of facility:
Davis-Besse Unit 1 2.
Scheduled date for next refueling outage? February 1990 3.
Scheduled date for restart from current refueling: October 1988 4.
Vill refueling or resumption of operation thereafter require a technical specification change or other license amendment? If ansver is yes, what in general vill these be? If ansver is no, has the reload fuel design and core configuration been reviewed by your Plant Safety Review Committee to determine whether any unreviewed safety i-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.T'8eactivity Control Systems, 3/4.3 Power Distribution Limits and 3/4.4 Reactor Coolant System.)

,Fifth Refueling Outage Major events completed during September:
High pressure injection line thermal sleeve repairs Reactor core refueling / core alterations Entered Mode 5 Secondary plant vacuum established Main feedpump turbine overspeed testing Steam Generator bubble tecting l
Containment Integrated Leakage Rate Test I
SFRCS (Steam and Feedvater/ Rupture Control System) hot functional 1
testing to field devices The fifth refueling outage is currently scheduled to be complete with entry into Mode 1 on October 28, 1988. The critical path remains the SFRCS modification.
Major modification testing is complete, however, system integration testing and calibrations to plant instrument devices is nov in progress.
L Major events upcoming in October include the Integrated Safety Features Actuation System Test, system lineups and restart required surveillance testing. These items vill dictate the actual completion of the fifth i
refueling outage.
