INTRODUCTION Quad-Cities Nuclear Power Station is composed of two Boiling Hater Reactors, each with a Maximum Dependable Capacity of 769 MWe Net, located in Cordova, Illinois.

The Station is jointly owned by Commonwealth Edison Company and Iowa-Illinois Gas & Electric Company.

The Nuclear Steam Supply Systems are General Electric Company Boiling Water Reactors.

The Architect / Engineer was Sargent & Lundy, Incorporated, and the primary construction contractor was United Engineers & Constructors.

The Mississippi River is the condenser cooling water source.

The plant is subject to license numbers DPR-29 and DPR-30, issued October 1, 1971, and March 21, 1972, respectively; pursuant to Docket Numbers 50-254 and 50-265.

The date of initial Reactor criticalities for Units One and Two, respectively were October 18, 1971, and April 26, 1972.

Commercial generation of power began on February 18, 1973 for Unit One and March 10, 1973 for Unit Two.

This report was compiled by Verna Koselke and Lynne Deelsnyder, telephone number 309-654-2241, extensions 2240 and 2185.

SUMMARY

OF OPERATING EXPERIENCE A.

Unit One Unit One segan operations for the month of May in Economic Generation Control (EGC). Tae unit remained in EGC with only minor interruptions to perform routine surveillances until May 6.

At 2100, a normal unit shutdown was initiated for a scheduled dual unit outage associated with the Unit Two refuel outage. At 0121 on May 7, the turbine was tripped and at 0141, the reactor was scrammed. At 0715, normal shutdown procedures vere completed.

From May 7 to May 15 battery testing was performed, control rod drive G-7 was replaced, as well as other maintenance activities involved for Unit One.

At 1620 on May 15, the reactor became critical, and at 0553 on May 16, the generator was synchronized to the grid. At 0556, the turbine was tripped to perform an overspeed test.

At 0640, the generator was again synchronized to the grid. A power ascent to full load was begun using control rods and recire pumps. At 0920 on May 17, full load was achieved.

Rod pattern adjust-ments were made while power levels were held constant. On May 18 and 19, routine surveillances were performed. At 0255 on May 19, while performing Main Steam Isolation Valve Closure Monthly Surveillance, the 1C M31V would not go to the 10% closed position. Therefore, a load reduction was taken to 595 MWe. At 0435, the MSIV closure time surveillance for the IC valve was completed. At 0805, a power ascent was begun.

786 MWe was reached at 0932.

On May 20 at 1721, the unit was placed in EGC.

From May 20 to May 24, the unit generated in EGC with only minor interruptions. At 1248, the unit was taken off of EGC to perform a load drop test. A power ascent to full load was taken and held until the test was completed. At 1825, power levels were adjusted and the unit was placed in ECC. The unit operated in EGC until 1032 on May 25 when it was taken off of EGC due to instabilities indicated in the "B" Recirc Pump Drive Water Flow.

Recire pumps were put to Master-Manual per the Shift Control Room Engineer. At 1510, load was increased from 779 MWe to full power. On May 26 at 0055, power level adjust-ments were made and the unit was placed in EGC.

The unit remained in EGC until May 28, when, at 0845 EGC was tripped and a power reduction was taken to 650 MWe to work on the "A" Main Steam Drain Tank Level control. Repairs were completed and the unit was placed in EGC at 1624, and operated in EGC until May 29.

At 0245, the unit was taken off of EGC and a power reduction to 720 MWe was taken.

At 0345, while testing the #4 control valve, the valve did not fast close during the last 10% travel and a B channel 1/2 scram was not received.

Therefore, a manual 1/2 scram on the B channel was taken, and then reset for testing. The manual 1/2 scram was again taken.

Same results occurred and a power reduction was immediately taken. At 0857, 325 MWe was reached. At 1050, another power reduction was taken with control rods at 285 MWe, Power level was held here while Maintenance attempted to repair the #4 control valve 10% open limit switch. At 0115 on May 30, a power reduction was taken to 250 MWe, and at 0220 the unit was placed 0027H/0061Z

in hot standby. Maintenance continued to work on the #4 control valve.

At 1705, repairs were completed, and the mode switch was placed in RUN.

At 1855, the generator was synchronized to the grid. An ascent to full power was begun using control rods and recire pumps.

Full load was achieved at 1100 on May 31 and was maintained through the end of the month.

B.

Unit Two The End of Cycle Nine 2efueling Outage activities continued normally for Unit Two during the month of May. The vessel was flooded, and the core was reloaded beginning at 0530 on May 24 and completed at 1704 on May 27.

Core reload was verified and CRD friction testing was performed on May 28 thru May 30.

PLANT OR PROCEDURE CHANGES TESTS, EXPERIMENTS, AND SAFETY RELATED MAINTENANCE A.

Amendments to Facility License or Technical Specifications Technical Specification Amendment No. 106 was issued on March 28, 1988, to Facility Operating License DPR-29.

This amendment incorporates changes to the Limiting Conditions for Operations, Surveillance Requirements and Bases of the 3.../4.4 Technical Specifications for the Unit 1 Standby Liquid Control System 1 compliance with 10CFR50.62.

Technical Specification Amendment Nos. 107 and 102 were issued on May 10, 1988, to Facility Operating Licenses DPR-29 and DPR-30.

These amendments incorporate revisions to applicable Techr.ical Speci-fications Limiting Conditions for Operation, Surveillance Requirements, and Bases which include changes to:

1) the number of HPCI and RCIC steamline high flow instrumentation required operable,

2) HPCI and RCIC high steam flow time delay setting,
3) and high steam flow instrument designation.

B.

Facility or Procedure Changes Requiring NRC Approval There were no Facility or Procedure changes requiring NRC approval for the reporting period.

C.

D.

Corrective Maintenance of Safety Related Equipment The following represents a tabular summary of the major safety related maintenance performed on Units One and Two during the reporting period. This summary includes the following: Work Requests Numbers, Licensee Event Report Numbers Components, Cause of Malfunctions, Results and Effects on Safe Operation, and Action Taken to Prevent Repetition.

UNIT 1 MAINTENANCE

SUMMARY

WORK REQUEST NO.: Q60630 LER NUMBER: NA COMPONENT:

System 1000 - Installed a larger impeller on the main pump and machined down those on the booster pump, 1-1001-65A.

CAUSE OF MALFUNCTION: There was no malfunction.

This was a special tset done to try and reduce excessive vibration of the pump.

RESULTS & EFFECTS ON SAFE OPERATION: There was no safety significance as there were three other pumps available for operation.

ACTION TAKEN TO PREVENT REPETITION: The test was proved successful and will be implemented on the remaining pumps for both units.

UNIT 2 MA'_.IENANCE

SUMMARY

There were no Deviation Reports or License Events Report associated with the Safety Related Work Request Log this month.
