--**' Dockst Ns. 50-336 Date: July 9, 1980 Completed By: G.H. Howlett III Telephone: 203/447-1971 X364 REFUELING INFORMATION REQUEST

1. Name of facility: Millstone 2

2. Scheduled date for next refueling shutdown: August 2, 1980

3. Schedule date for restart following refueling: September 28, 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 licensing action and supporting information:

The schedule for submitting license action is as follows:

Basic Safety Report 3-6-80 Additional licensing documentation in support of cycle four (4) operation will be provided in response to Fuclear Regulatory Commission staff questions. ~

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 s are 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 (bl 144

8. The present licensed spent fuel pool st.,.' age 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 ifcensed capacity:

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

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