l l

The Independent Spent Fuel Storage Installation (ISFSI) will be capable of storing the entire FSV core (1482 HTGR elements) with storage sphce for an additional 138 HTGR elements.

Under Agreements AT(04-3)-633 and DE-SC07-791001370 between Public Service Company of Colorado, General Atomic Company, and DOE, spent fuel discharged during the defueling process will be stored by DOE at the Idaho Chemical Processing Plant.

The storage capacity is presently sized to' accommodate eight fuel segments.

It is estimated that the eighth fuel _ segment will be discharged in 1992.

Discussions concerning the disposition of ninth fuel segment are in_ progress with DOE.- Nuclear Operations at Fort St. Vrain were terminated August 29, 1989.
