SUMMARY

OF OPERATING EXPERIENCE UNIT 1 The unit entered the reporting period at a power level of 1030 MWe (1001 reactor power). The unit performed very well having an Availability Factor of 100% and a Capacity Factor of.92.2%. On April 26 power was reduced to 55% for the purpose of reconnecting the level sensors on the Bergen-Patterson steam generator snubber expansion tank. Reactor power was returned to 100% on the same day. The unit was on-line the entire month and ended the reporting period on-line at a power level of 1018 MWe (99.5% reactor powe r). UNIT 2 The unit entered the reporting period at a power level of 1060 MWe (100% reactor power). On April 3 at 1731 hours lightning hit close to the Station resulting in a reactor trip. The unit was made critical on April 4 at 1920 hours and tripped on April 5 at 0231 hours due to 2A steam genera-tor lo-lo level. The unit was made critical at 0340 hours and tripped again at 0615 hours due to 2A steam generator lo-lo level. The unit was made critical on April 5 at 1205 hours and was synchronized to the grid at 1520 hours. On April 9 it was necessary to reduce power due to problems associated with diesel generators "O" and "A". The unit was started back up to 100% on April 10. On April 20, it wan necessary to reduce power to add oil to 2A reactor i coolant pump and to do turbine stop valve testing. On April 28 c - 2200 hours it was necessary to reduce power to 50% for ths purpose of identifying R.C.S. leakage. Power was startec back to 100% on April 29. Overall the unit performed very well being 93.6% available with a Capacity Factor of 82.8%. The unit remained on-line for the remainder of the month and ended the month at a power level of 895 MWe (84% reactor power). 6

~ Page 1 of 3 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 cora 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 j supplier, unreviewed design or performance analysis methods, significant changes in fuel design, new operating procedures. 1 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. 4, l 9. The projected date of the last refueling that can be discharged to the spent fuel pool assuming the present licensed capacity. 6

Page 2 of 3 Unit 1 - Answers 1. Zion Unit 1. 2. January 1, 1981 is the scheduled date for the next refueling outage. 3. February 10, 1981 is the scheduled date for initial criticality following refueling. 4. The reload ruel design and core configuration has not under-gone On-Site and Off-Site Review. However, no Technical Specification changes or license amendments are anticipated. The On-Sitt and Off-Site review of the Cycle VI fuel design and core configuration is currently scheduled for completion by November 1, 1980. 5. If the need for Technical Specification changes of other license amendments arise from the review in 4 above, then November 1, 1980 will be the scheduled date for submitting the requi ed information. 6. No important licensing considerations are anticipated with this refueling. 1 7. The number of fuel assemblies !I a) in the core is 193, and b) in the spent fuel storage pool, which have been discharged from Zion Ur.it 1, is 248. 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 is scheduled to begin within the next two months. 9. October, 1992 is the projected date of the last Zion Unit 1 refueling which can be discharged to the spent fuel pool assuming the present licensed capacity. i

Page 3 of 3 Unit 2 - Answers 1. Zion Unit 2 2. May 2, 1980 is the scheduled date for the next refueling shn*~ vn. 3. June 27, 1980 is the scheduled date for initial criticality following refueling. However, the dates for this refueling are subject to change. 4. No Technical Specification changes or other license amend-ments are anticipated. The reload fuel design and core configuration for Cycle V has undergone on-site review. The off-site review has not been completed. The on-site review stated that no Technical Specification changes or license mnendments are necessary. 5. If unreviewed safety questions arise from the review in 4 above, then January 10, 1980 would have been the scheduled date for submitting a Reload Safety Evaluation Report on Zion Unit 2 cycle 5. 6. No important licensing considerations are anticipated with this refueling. 7. The number of fuel' assemblies a) in the core is 193, and b) in the spent fuel storage pool which have been discharged by Zion Unit 2 is 188. l 8. The present licensed spent fuel pool storage capacity (shared with Zion Unit 11 is 2112 fuel assemblies. The installation of the new storage racks is scheduled to begin within the next two months. 9. October, 1992 is the projected date of the last Zion Unit 2 refueling, which can be discharged to the spent fuel pool assuming the present licensed capacity, i}}
