REFUELING INFORMATION (CONTINUED) )

t

. 9. Th> projected date of the 1986 under the Three Party Agreement (Con-

!

last refueling that can be tract AT (04-3)-633) between DOE, Pub 11c l discharged to the spent fuel Service Company of Colorado (PSCo), and pool assuming the present General Atomic Company.* l licensed capacity. l

• The 1986 date is based on the understanding that spent fuel discharged during the term of the Three Party Agreement will be shipped to the Idaho National Engineering Laboratory for storage by DOE at the Idaho Chemical Processing Plant (ICPP). The storage capacity has evidently been sized to accomodate fuel which is expected to be discharged during the eight year period covered by the Three Party Agreecent.
