The 1996 estimated date is based on the understanding that' spent fuel' discharged during the term of the Agreements will.'be stored by DOE'at

The storage capacity has evidently been sized to accommodate ~ eightL fuel segments.. It' is i

estimated that the eighth fuel segment will be discharged in 1996.
