INTRODUCTION Quad-Cities Nuclear Power Station is composed of two Boiling Water located Reactors, each with a Maximum Dependable Capacity of 769 MWe net, in Cordova, Illinois. The Station is jointly owned by Commonwealth Edison The Nucleat Steam Company and lowa-Illinois Gas & Electric Company.

The Supply Systems are General Electric Company Boiling Water Reactors.

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

denser cooling method is a closed-cycle spray canal, and 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 1 and 2 respectively were October 18, 1971, and April 26, 1972. Commercial generation of power began on February 18, 1973 for Unit I and March 10, 1973 for Unit 2.

SUMMARY

OF OPERATING EXPERIENCE A.

UNIT ONE Unit One began the reporting period holding a load of 815 May 1-9:Over these initial nine days, an average load of 814 MWe was MWe.

held, except on May 3 On that day load was dropped to 700 MWe for the weekly turbine test. After the tests were completed, load was held for an additional three hours, per the Load Olspatcher, resulting in a load of 768 MWe for the day.

May 10-12: On May 3 at 2330, load was dropped at 100 MWe/ hour to perform the weekly turbine tests. At 2335, an alarm for the 8 Recirc Pump Motor Lower Lube Oil HI/Lo Level was received.

Seven Hundred HWe was reached and held at 0035 on May 10 and the tests were completed at 0145 Load was held at 700 MWe until 0515 At that time load was increased at various rates until 0800 when it was dropped back to 400 MWe at a rate of 100 MWe/ hour. The Drywell was deinerted and an entry was made to add oil to the Recirc Pump Motor Lower Bearing in both loops. At 1415 load was increased at 100 MWe/ hour for two-hours, then at 5 MWe/ hour until 0700 on May 12.

The resulting daily average load for May 10,11, and 12 was 614, 735 end 809 MWe, respectively.

May 13-21: With the exception of May 17, load was held at an average of 809 MWe. On May 17 a load of 708 MWe was achieved due to per-formance of the weekly turbine tests and load reductions per the Load Dispatcher's_ request.

May 22-27: Load was held at 812 MWe on May 22 until 1900, when it was dropped in preparation for a Maintenance Outage to repair a leaking seal ring on I A Feedwater Check Valve. The Unit was tripped off-line at 2337 and the reactor was manually scrammed at 0050 on May 23 IA and IB Recirc Other work items performed during this outage were:

MG Sets were rebrushed, Pilot Valves were replaced in B, C, l', and E Electromatic Relief Valves, and miscellaneous valves were repaired.

The reactor was pulled critical at 2003 on May 24, and the generator was put on line at 0349 on May 25 Load was increased until 0500, when it was held at 230 MWe to perform scram timing on 88 control rods. At 1100 load was increased to 400 MWe and special rods maneuvers were performed for the Nuclear Engineer.

Load was then increased to 500 MWe for a Xenon soak. At 1130 on May 26 load was increased at various rates until it was held at 2400 on May 27

--r

May 28-31: On May 28 load was held at 803 MWe.

At 0145, on May 29, load was dropped to 750 MWe to switch reactor feed pumps and was then increased to 807 MWe at 092J.

Load was held until 0430 on May 31.

At that time load was dropped to 700 MWe to perform the weekly turbine tests, however, the Load Dispatcher requested that the Unit drop to 650 MWe. Load was held until 0615 when it was then increased at various rates until 804 MWe was reached and held. The Unit ended the reporting period in that state.

B.

UNIT TWO May 1-8: Unit Two began the reporting period holding a load of 783 MWe.

Although load was held, with the exception of weekly turbine tests on May 2, the average load was 766 MWe. This gradual drop in maximum load is attributed to a limiting control rod pattern.

May 9-11: At 0000 on May 9, load was dropped to 600 MWe to perform rod moves 'for the Nuclear Engineer. Load was increased at 5 MWe/ hour unitt 2l00 on May 10.

On May 10 the coastdown for End of Cycle Five began. At 2220 the 2E condensate demineralizer was taken out of service due to high post strainer D.P.

This necessitated dropping load on May 11 to backwash and precoat 2G and 2F demineralizers.

The average daily load for May 9,10, and 11 was 648, 755, and 762 MWe.

May 12-15: Load was held over this four day period at an average of 761 MWe.

Operational occurrences during this period included restoration of the 2E condei.; ate demineralizer on May 12.

May 16-20: On May 16 load was dropped for the weekly turbine tests, then held an additional four hours for the Load Dispatcher.

Load was again dropped for the Load Dispatcher on May 17 for four and one hal f hours. The resulting daily average load was 729 MWe on May 16, and 705 MWe on May 17 On May 18,13, and 20 load was held at an average of 746 MWe.

May 21-22: On both of these days the Load Dispatcher requested load to be dropped for three and one half hours each day. The resulting daily average loads were 709 and 719 for May 21 and 22 respectively.

May 23-27: Lead was held for this five day period with the exception of the weekly turbine ?-sts on May 24. However, due to deratings, the tests had little etrect on load. The average load over this period was 718 MWe.

(

y

May 28-31: On May 28, at 0115, load was reduced to 550 MWe at the request of the Load Dispatcher. Load was later increased, starting at 0600, at various rates until it was held at 1445 The average load for the day was 666 MWe, Load was held on May 29 However, due

to all lift' pumps tripping off at 0930, and the plant going on full river operation, a large rise in power occurred due to the using of The average load for the day was 712.1We.

On May 30 at 0030, power was dropped to 500 MWe for the Nuclear At this time the turbine weekly tests were performed and Engineer.

condenser flow was reversed. At 0335 load was increased at 5 MWe/ hour.

The load increase continued through May 31 and the Unit ended the reporting period a'; 745 MWe and increasing at 5 MWe/ hour.

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

Amendments to Facility License or Technical Specifications On April 16, 1981, Amendments 66 and 60 were issued to DPR-29 and DPR-30 respectively. These Amendments consist of changes in the Technical Specifications for each of the two units which change setpoints for certain system settings. These changed setpoints are for:

1) Turbine Condenser Low Vacuum Scram; 2) Main Steamline Low Pressure isolation; 3) Main Steamline High Flow' Isolation; 4) ECCS-ADS Interlock, and

5) ECCS Fill System High Pressure Alarm. These changes in instrument and system setpcint have been nade to reduce the number of nuisance alarms a,d spurious trips caused by set-point drift.

On April 20, 1981 Amendments 67 and 61 were issued to DPR-29 and DPR-30 respectively. These Amendments eliminate the requirement to reduce reactor power to below 50 percent of rated power when the main steam isolation valve closure time verification is performed.

On April 20, 1981, Amendments 68 and 62 were issued to DPR-29 and DPR-30 respectively. These Amendments eliminate the requirement for continuous monitoring of the primary contain-ment inerting system make-up as a means of monitoring the containment for gross leakage.

On April 24, 1981, Amendments 69 and 63 were issued' to DPR-29 and DPR-30 respectively. These Amendments remove reactor water cleanup isolation valve MO-1201-80 from Table 3 7-1 of the Technical Specifications and excludes the valve from the

-surveillance requirenent described in Section 4.7.D.

On May 13, 1981, Amendment 71 was issued to DPR-29 This Amendment extends the MAPLHGR curve for a mixed-oxide fuel bundle to 50,000 MWD /ST planar average exposure. This w!Il
