'The storage capacity !is presently sized to accommodate eight fuel segments. It is estimated 1 ,

that the eighth fuel segment will be discharged in 1991. Discussions-concerning the disposition of ninth fuel segment are in. progress with 00E. Nuclear Operations at Fort St. Vrain.were terminated-August 29, 1989.
