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

• • Underl Agreements AT(04-3)-633 and DE-SC07-791001370 between Public

-Service Company of Colorado, General Atomic Company, and 00E, spent fuel discharged during the defueling process will be stored by DOE at 1

-the Idaho Chemical Processing Plant. _ The storage capacity is presently limited to 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 00E. -Nuclear Operations at Fort St. Vrain were terminated August 29, 1989.
