REFUELING INFORMATION Date:
August 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 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 Safety Review Committee to determine whether any unreviewed safety questions are associated with the core reload (Ref. 10 CTR Section 50.59)?
Ans: The Reload Report requires standard reload fuel design Technical 5pecifications changes (2. Safety Limits and Limiting Safety System Settings, 3/4.1 Reactivity Control Systems, 3/4.2 Pover_ Distribution Limits and 3/4.4 Reactor Coolant System.)
5.
Scheduled date(s) for submitting proposed licensing action and supporting information:
Submitted May 18, 1988 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.
The highly absorbing silver-indium-cadmium axial power shaping a.
rods vill be replaced with reduced absorbing inconel rods.
b.
The discrete neutron sources vill be removed from the core and not
- replaced, c.
The physics testing has been reduced in scope.
7.
The number of fuel assemblies (a) in the core and (b) in the spent fuel storage pool, and (c) the new fuel storage areas.
l (a) 0 (b) 445 (e) 0 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.

SUMMARY
August 1988 Major Events Completed During Augusti Auxiliary feed pump turbine overspeed trip testing and pump to motor coupling and alignment Cooling tower maintenance Motor operated valve maintenance program Inservice inspections completed High pressure injection thermal sleeve repairs Condenser vacuum established Reactor coolant pump seals changed out The fifth refueling outage is scheduled to be complete on October 12, 1988.
The new end date is a result of two major plant modification durations being extended. The first mod, SFRCS, has been impacted by emergent items discovered during the post modification test process which requires engineering evaluation and disposition.
Second, thermal sleeve repairs have taken longer than anticipated due to difficulties experienced in velding the safe ends to piping nossles.
