l. INTRODUCTION-

. Qua'd Citie's Nuclear Power Station is composed of two Boiling Water Reactors and Steam Turbine / Generators, each with a Maximum Dependable Capacity of 769 MWe

- Net, located in Cordova. lilinois. The Station is jointly owned by Commonwealth Edison

-. Company and MidAmerican Energy Company. The Nuclear Steam' Supply Systems are G'eneral Electric Company Boiling Water Reactors." The Architect / Eng;neer 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 Lynne Hamilton and Debra Kelley, telephone number

. 309-654-2241, extensions 3114 and 2240, respectively.

SUMMARY

OF OPERATING EXPERIENCE l

i A. Unit One  :

i

' Quad Cities Unit One began the month of May with the reactor critical. The )

main generator was synchronized to the grid on May 1,~ 1999, at 6:05 a.m. On l May 21,1999, at 8:46 p.m., Unit 1 reactor auto-scrammed on Scram l Discharge Volume (SDV) hi-hi level. The reason for the scram was the  !

following: When the Reactor Wate'r Cleanup system was restarted, it caused '

one or more relief valves to lift at their setpoint of 1450 psig. The hot water from the relief valves flashed to steam in the lines going to the Reactor Building Equipment Drain Tank (RBEDT) and also flowed into the SDV drain lines connected to the RBEDT header lines. The put steam into the SDV, causing i the temperature sencing hi-hi level instruments to trip, which in turn caused the scram. On May 22,1999, startup activities commenced. On May 23,1999, at 5:41 a.m., Unit 1 went critical, and at 12:29 p.m., the generator was synchrontred to the grid. Unit One operated throughout the remainder of the month at full power with minor down power operations for routine maintenance and surveillance testing.

B.' Unit Two -

Quad Cities Unit Two began the month of May operating at full power, Unit ,

Two operated throughout the month at full power with minor down power ~ l operations for routine maintenance and surveillance testing.  ;
