APRIL

SUMMARY

OF OPERATING EXPERIENCE UNIT 1 The unit entered the reporting period at a power level of 640 MWe (60% reactor power). On April ~ 25th at 0125 hours, the unit became critical due to high' vibration of main generator. The unit remained critical until reactor trip at 0320 hours on April 30. The reactor trip was due to 1N31 source range instrument failure during shutdown. Unit 2 The unit entered the reporting period off-line for the continuation of Cycle IX, X Refueling Outage. The unit remained off-line the entire month. 1109t 0591A

1: 4 REFUELING INFORMATION REQUEST Questions: 1. Name of facility. 2. Scheduled date for next refueling shutdown. 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 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) in 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. l Page 1 of 3 l I I 1109t l 0591A

l*.s Unit 1 - Answers

1. > Zion Unit 1 2.

January 7, 1988 is the currently scheduled shutdown date. Because of the delayed startup of the current cycle, this date is subject to change. 3. Based on the above shutdown, the initial criticality following refueling would occur mid-March,1988. 4. No required Technical Specification changes have been identified for the 'next cycle. There is a concern on the extent of Steam Generator tube plugging in Steam Generator "B" that may occur during the next outage. Using sleeving as a method of Steam Generator repair, the effective total plugging should remain below 10%. The reload safety review is planned for - October,1987 and the On-Site Review will be held af ter that review. 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 556. 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,1986 study. I i Page 2 of 3 i 1109t 0591A m

j.,,.. Unit 2 - Answers 1. Zion Unit 2 2. In current refueling outage since March 25, 1987. Next refueling outage scheduled to begin in September,1988. 3. July 1,1987 is the approximate date for initial criticality after refueling. 4. No Technical Specification changes have been identified. An initial reload safety evaluation review was held in December 1986. Another review, based on the extended operation of Unit 2 Cycle 9, is planned for May, 1987. The station On site Review is held after the reload. safety review. 5. None 6. None. 7. The number of fuel assemblies a) in the core is 0, and b) in the spent fuel storage pool from Zion Unit 2 is 785 of which 80 are new assemblies and 113 are reinserts planned to be used in the next core. 8. The present licensed spent fuel pool storage capacity (shared with Zion Unit 1) 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,1986 study. l Page 3 of 3 l l 1109t 0591A
