s REFUELING INFORMATION

1. Name of Facility. Fort S t. Vrain, Unit No. 1

2. Scheduled date for next refueling shutdown. January 1, l'81

3. Scheduled date for restart following refueling. March 1, 1981

4. Will refueling or resu=ption of operation thereafter require a technical specification change or other license amend =ent? No If answer is yes, what, in general, will these be?

If answer is no, has the reload The Plant Operations Review Committee will fuel design and core configura- review any questions associated with the tion been reviewed by your Plant core reload.

Safety Review Committee to deter-mine whether any unreviewed safety questions are associated with the core reload (Reference t 10CFR Section 30.59)? I If no such review has taken place, when is it scheduled? July 1, 1980

5. Scheduled date(s) for submitting -

proposed licensing action and supporting information.

6. Important licensing considera- -----

tions associated with refueling, e.g., new or different fuel de-sign or supplier, unreviewed design or perfor=ance analysis methods, significant changes in fuel design, new operating pro-

! cedures.

7. The number of fuel asse=blies a) 1482 HTGR fuel elements.

(a) in the core and (b) in the spent fuel storage pool. b) 244 spent HTGR fuel elements.

8. The present licensed spent fuel Capacity is limited in size to about one-pool storage capacity and the third of core (approximately 500 HTGR size of any increase in licensed elements) . No change is planned.

storage capacity that has been requested or is planned, in number of fuel assemblies.

s REFUELING INFORMATION (CONTINUED)

licensed capacity.

• 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 rear period covered by the Three Party Agreement.
