Schedule date for restart following refueling: September 1,1980 l

4.-

Will refueling or resumption of operation thereafter require a technical

.s, ecifica. tion change.or other license amendment?

p r.

, Technical. Specification changes will be necessary.as a result of the change in fuel.and safety, analysis su'pplier

.i 5.

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

The schedule for submitting proposed license action is as follows:

Basic Safety Report 3-6-80 ECCS Results 4-1-80 Reload Safety Evaluation 5-1-80 i

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:

Cycle 4 will be unique in that it will be the first where the fuel and safety analysis will be supplied by Westinghouse.

7.

The number of fuel assemblies (a) in the core and (b) in the spent fuel storage pool:

(a)

In Core:

217 (b) 144 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:

667 9.

The projected date of the last refueling that can be discharged to the spent fuel pool assuming the present licensed capacity:

1985, Spent Fuel Pool, full core off load capability is reached.

l 1987, Core Full, Spent Fuel Pool contains 648 bundles.
