REFUELING INFORMATION REQUEST

1. Name of facility: Millstone 2

2. Scheduled date for next refueling shutdown: Currently in End of Cycle 9 refuelina.

3. -Schedule date for restart following refueling: April 20, 1989

4. Will refueling or resumption of operation thereafter require a technical s; ;ification change or other license amendment?

Technical Specification changes for Cycle 10 Operation were approved by the NRC on MARCH 20, 1989.

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

None.

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 10 will be unique in that it will be the first cycle where the fuel and sarety analysis will be supplied by Advanced Nuclear Fuels for Millstone Unit 2.

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

(a) In Core: (a) 217 (b) 640

-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:

Currently 1277

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

1994, Spent Fuel Pool Full, core off load capacity is reached (without consolidation 3). ,

1998, Core Full, Spent Fuel Pool Full 2009, Spent Fuel Pool Full, core off load capacity is reached -

contingent upon full scale storace of consolidated fuel in the Spent Fuel Pool.
