REFUELING INFORMATION RE0VI11

. Questions:

1.

.Name of facility.

2.

Scheduled date for next refueling shutdown.

3.

Scheduled date for restart following refueling.

4.

Hill refueling or resumption of operation thereafter-require a technical specification change or other license amendment?

t If answer is'yes,-what, in general, will these be?

f If answer is no. has the reload fuel design and core configuration been reviewed by your Plant Safety Review Committee to determine whether any unreviewed safety questions are associated with the core reload (Ref. 10 CFR Section 50.59)?

i 1

If no such review has taken place, when is it scheduled?

5. -

Scheduled date(s) for' submitting proposed licensing action and supporting information, i

6.

Important licensing considerations associated with refueling, e.g.,

new or different fuel design or supplier, unreviewed design or performance analysis methods, significant. changes in fuel design, new operating procedures.

3;

.i

7.

The number of fuel assemblies: (a) in the core and (b) in the spent 3

. fuel storage pool.

8.

The present licensed spent fuel pool storage capacity and the: size of 4

any increase in licensed' storage capacity that.has been requested or o

is planned, in number of fuel assemblies, i:

J 9.

The projected-date of the last refueling that can be discharged to l:

the spent fuel pool assuming the present licensed capacity.

Yes.

Technical Specification changes will be required to include the-Hestinghouse VANTAGE fuel design being loaded for 21C13, and effects of the vessel fluence reduction program beginning with Z1C13.

-i 5.

License amendments for the Z1C13 reload are expected to be submitted.

j in'the Fall of 1990.

6.-

License considerations associated with the Z1C13 reload include the,

l new VANTAGE fuel design, and the new LOCA analysis with higher core i

I power. peaking factors required for the low-low-leakage loading 4 pattern used in Z1C13.

7.

Tte number of fuel assemblies 1:

-a) in'the' core is 193, and L

b) in the. spent fuel storage pool from Zion Unit 1 is 708.

rerack the Spent Fuel Pool to increase storage capacity to 3137' l

assemblies.

L 9.

Zion Station will lose full core discharge capability (for both.

J

. units) in May 1993, at the end of Unit 2 Cycle 13, based on the
