BEFUELING INf0RMATION REQUEST December 1990 1

Name of facility: Millstonql 2,

Scheduled date for next refueling shutdown: February 1.1991.

3.

Scheduled date for restart following refueling: March 29.1991 4.

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

As a result of the new fuel desien. Technical Soecifications chances to the Axial Flux Difference. Heat Flux Hot Cha'nnel Factor, arid Refueline Water Storang Tank sec-tions will be reagired. Furthermore the Fuel Storace section of Desien Features will be chang _e.1_to allow continued recionalized storace of spent fuel in the spent fuel 1

ppol. Also, the Instrumentation section will be changed to reflect a new High F. ix at Shutdown setpoint, 5.

Scheduled date for submitting licensing action and supporting information.

_All Technical Specification changes submitted 6.

Important licensing considerations associated with refueling, e.g., new or different fuel design or supplier, unreviewed design of performance analysis methods, signifi-cant changes in fuel design, new operating procedures:

Cycle 4 fuel assemblies will be of the Westinchouse Vantane 5H design. This design neludes @bris filter bottom nozzles, intermediate flow mixinc crids, intecral fuel rod

~~

~

,urnable absorbers. and axial blankets.

7.

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

(a): 193 (b): 160 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:

Present size - 756.

No increase reauested.

9.

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

End of cycle 5.
