3/11/83 Coneleted By: J. Gibson Telephone: (203) 447-1791 ht. 4431 REFUELING INFORMATION REQUEST 1.

Name of facility: Millstone 2 2.

Scheduled date for next refueling shutdown:

May 28, 1983 3.

Schedule date for restart following refueling: September 17, 1983 (16 wks outage) 4.

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

It is anticipated that Cycle 6 operations will require Technical Specification changes or other License amendments.

5.

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

Safety Analyses: March 15, 1983 Steam Generator Licensing Action:

April 15, 1983 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:

Additional plugged steam generator tubes will result in potential reactor coolant flow reduction.

Currently planning to install sleeves in steam generator tubes.

7.

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

(a) In Core:

217 (b) 288 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 of load capability is reached.

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