SUMMARY

OF OPERATING EXPERIENCE UNIT 1 The unit entered the reporting period in cold shutdown for the continuation of the scheduled refueling outage. On May 5, 1988 at 0027 hours3.125e-4 days <br />0.0075 hours <br />4.464286e-5 weeks <br />1.02735e-5 months <br />, the unit was made critical and on May 7, 1988 at 1705 hours0.0197 days <br />0.474 hours <br />0.00282 weeks <br />6.487525e-4 months <br /> the

- Reactor tripped on low-low level steam generator level due to a broken lead on the main generator's meter. May 8, 1988 at 2254 hours0.0261 days <br />0.626 hours <br />0.00373 weeks <br />8.57647e-4 months <br />, the reactor.was made critical and May 9,1988 at 0738 hours0.00854 days <br />0.205 hours <br />0.00122 weeks <br />2.80809e-4 months <br /> the unit was synchronized to the grid. The Unit remained on line the remainder of the month ending at a power level of 1079 MWe (99% reactor 7.ower) and having

.an availability factor of 73.2%.

UNIT 2 The unit entered the reporting period at 1091 MWe (98% reactor power). On May 18,1988 decreased load to 55% power to funnanite the 20 Steam Generator upper manway secondary side steam leak. On May 20th increased power to 100% and on May 23,-1988, decreased reactor power to 55% to perform an inspection inside the missile barrier on the Reactor Coolant pump deck for significant steam leaks. The unit remained on line the entire reporting peroid, ending at a power level of 1092 MWe (98% reactor power) and having an availability factor of 100%.

l REFUELING INFORMATION RE0 VEST Questions:

fl . Name of facility' .

2. -Scheduled date for next refueling snutdown.

3. Scheduled date for restart following refueling.

.4. Will 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, 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)?

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

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

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

new or dif ferent fuel design or supplier, unreviewed design or I performance analysis-methods, significant changes in fuel design, new operating procedures.

7. The number of fuel assemblies (a) in the core and (b) in the spent fuel storage pool. i

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. Next. refueling outage is currently scheduled to begin on August 31, 1989.

3. The initial criticality following refueling is scheduled for November,1989.

4. .No Technical Specification changes have been identified for the next cycle. The reload safety review is planned for May 1989. The On-site

Review will be held af ter that review.

4. The reload safety review was held in October,1987 and no unreviewed safety questions were identified for the proposed reload. The On-Site Review for the reload (0SR/0ll/88) was completed in April,1988 and identified no unreviewed safety questions associated with the core reload.

5. None

6. None

' 7. The number of fuel assemblies a) in-the core is 193, and b) in the spent fuel storage' pool from Zion Unit 1 is 632. .Four.of the recently discharged 80 assemblies were originally lion Unit 2 assemblies.

8. The present licensed spent fuel pool storage capacity (shared with Zion Unit 2) is 2112 fuel assemblies. The installation of the new storage racks has been completed.

9. In 1995, Zion Station will lose full core discharge capability. This date is based on a December,1987 study.
