Name of facility:

Millstone 2 2.

Scheduled date for next refueling shutdown: July 1, 1980 3.

Schedule date for restart following refueling: September 1, 1980 4.

Will refueling or resumption of operation thereafter require a technical specification change or other license amendment?

Technical Specification changes will be necessary as a result of the change in fuel and safety analysis supplier.

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 2-1-80 ECCS Results 4-1-80 Reload Safety Evaluation 5-1-80 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 che spent fuel

~

storage pool:

(a)

In Core:

21 7 (b) 144 8.
