SUMMARY

Of_0PERATING EXPERIENCE UNIT 1 The Unit entered the-reporting period at a power level of 1088 MHe (99%

reactor power).

On March 1st at 2225 hours0.0258 days <br />0.618 hours <br />0.00368 weeks <br />8.466125e-4 months <br />, Unit I went off-line. At 2236 hours0.0259 days <br />0.621 hours <br />0.0037 weeks <br />8.50798e-4 months <br /> on March 1st the reactor was shutdown-due-to Diesel-

. Generator 'O' inoperability, which was required by Tech Specs.

4 On March 29th at 1213 hours0.014 days <br />0.337 hours <br />0.00201 weeks <br />4.615465e-4 months <br /> the reactor was made critical and at 1238 hours0.0143 days <br />0.344 hours <br />0.00205 weeks <br />4.71059e-4 months <br /> the reactor was shutdown due to. excessive stroke' time on IA and IC Main Steam Isolation Valves, The unit remained in Hot Shutdown the rest of the report period.

Availability factor of 3.0%.

4 UNIT 2 The Unit entered the report period at a power level of 1073 MWe (99%

reactor power). On March 1st at 2336 hours0.027 days <br />0.649 hours <br />0.00386 weeks <br />8.88848e-4 months <br /> the. unit went off-line.

At 2346 hours0.0272 days <br />0.652 hours <br />0.00388 weeks <br />8.92653e-4 months <br /> the reactor was shutdown due'to Diesel Generator '0' inoperability, which was a Tech _ Spec requirement.

On March 21st at 0000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> the unit was shutdown due to the start of the ten weeks refueling outage.

The unit remained in Cold Shutdown for the rest of the report period.

Availability factor of 3.2%.

REFUELING INFORMATIotLREQUESI

. 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?

If answer is yes, what, in general,;will these be?.

If answer is no, haslthe 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)?-

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

5.

Scheduled date(s) for submitting proposed licensing action and.

a supporting information.

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.

7.

The number of fuel assemblies: (a).ih the core and (b)'.in the spent

~

fuel storage pool.

8.

The present licensed spent fuel pool storage capacity-and the. size of any increase in licensed storage capacity that has been requested or is planned, in number.of fuel. assemblies.

9.

The projected date of the last refueling that can be discharged to the spent fuel pool assuming the.present licensed, capacity.

2.

Schedule date for next_ refueling will be set once the unit is back on-line.

i 3.

'To be scheduled.

4.

Yes. Technical Specification changes will be required to include the-

-i Hestinghouse VANTAGE fuel ~ design being' loaded-for ZlC13, and effects of.the vessel fluence reduction program beginning with ZlCl3.

l 5.

License amendments for the ZlC13 reload are expected to be submitted j

in the Fall of 1990.

~

6.

License considerations associated with the Z1Cl3< reload-include the 1

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

power peaking factors-required for the.. low-low-leakage loading i

pattern used in ZlCl3.

1 7.

The number of fuel assemblies a) in the core.is 193, and b) in the spent fuel storage pool from Zion Unit I-is-708.

8.

.The present licensed' spent fuel pool storage capacity (shared with-Zion Unit 2) is 2112 fuel assemblies.

Plans are.being developed to-i rerack the Spent Fuel Pool to increase storage tapacity'to 3137_

i assemblies.

9.

Zion Station will lose' full core discharge-capability (for both units) in May 1993, at the end of Unit 2 Cycle 13; based on the -

i latest Nuclear Stations Refueling Schedule.

Full core discharge capability for a single core w11_1 be lost in November,.1994, at the end of Unit 2 Cycle 14.

Unit'2 - Answers l '.

Zion Unit 2-2.

Cycle 11 officially entered refueling on March 21' 1990.

h 3.

Cycle 12 is scheduled to start up May 29, 1990.

4.

The_ reload safety evaluation meeting for 22C12 was held on

' December-12,-1989, and concluded no licenst amendments would be!

required _for Z2Cl2 operation. However, a letter from Nuclear Fuel Services to Zion (03/20/90) stated that-a Technical-Specification; bases' change-may be required to reflect a change in'the rod bow penalty used in reload design.

5.

To_be determined.

6.

The change in rod bow penalty used in reload design needs-to be-resolved prior to operation of.Z2C12.

J 7.

The number of fuel assemblies i

a) in the core is 0, and b) in the spent fuel storage. pool from Zion Unit 2_is-857, 8.

The present Ilcensed spent fuel pool storage capacity (shared with'-

Zion Unit 1) is 2112 fuel assemblies.

Plans are being' developed to i

rerack the Spent Fuel Pool to increase storage capacity to 3137 assemblies.

9.

Zion Station will lose full core discharge capability-(for both units) in-May 1993, at the end of Unit-2 Cycle 13, based on the:

i latest Nuclear Stations Refueling Schedule.

Full core discharge 1

capability for a single core will be lost in Novembct, 1994, at the end of Unit 2 Cycle 14.
