SUMMARY

March 1988 3/1/88 - 3/10/88 Reactor power continued to be reduced during the month to six percent due to Cycle 5 coastdown.

3/10/88 - 3/31/88 Plant shutdown and cooldown was initiated to perform scheduled maintenance and refueling activities. The following are the more significant activities performed during this period.

1.

Baseline flov test on Main Generator Seal Oil System.

2.

I!ajor Control Room modifications began including removal of Steam and Feedvater Rupture Control System Panels for replacement.

3.

Turbine overhaul work began including removal on the generator field which was shipped to Chicago for rework.

4.

Significant cooling tower repairs began.

5.

Pre-outage work continued on major modifications to Makeup System as part of Feed and Bleed enhancements.

6.

Performance testing on the Containment Air Coolers, Decay Heat Exchanger 1-1 and Component Cooling Vater Heat Exchanger 1-1 vere completed.

REFUELING INFORMATION Date:

March 1988 1.

Name of facility:

Davis-Besse Unit 1 2.

Scheduled date for next refueling outage? harch 1988 3.

Scheduled date for restart following refueling September 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 answer is no, has the reload fuel design and core configuration been reviewed by your Plant Safety Review Committee to determine whether any unreviewed sefety 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 Specifications changes (2. Safety Limits and Limiting Safety System Settings, 3/4.1 Reactivity Control Systems, 3/4.2 Power Distribution Limits and 3/4.4 Reactor Coolant System.)

5.

Scheduled date(s) for submitting proposed licensing action and supporting information:

May 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.

1.

The highly absorbing silver-indium-cadmium axial power shaping rods vill be replaced with reduced absorbing inconel rods.

2.

The discrete neutron sources vill be removed from the core and not replaced.

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.

(a) 177 (b) 204 - Spent Fuel Assemblies (c) 64 - New 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 i

or is planned, in number of fuel assemblies.

Present:

735 Increased size by: 0 (zero) 9.

The projected date of the last refueling that can be discharged to the j

spent fuel pool assuming the present licensed capacity.

1 Date:

1995 - assuming ability to unload the entire core into the spent fuel pool is maintaine_d I
