l. INTRODUCTION .

Quad-Cities Nuclear Power Station is composed of two Boiling Water 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 lowa-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 con-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 I and 2 respectively were October 18, 1971, and April 26, 1972. Commercial generation' of power began on February 18, 1973 for Uni t 1 and March 10, 1973 for Unit 2.

This report was compiled by Becky Brown and Robert Tubbs, telephone

! number 309-654-2241, extensions 245 and 174.

SUMMARY

OF OPERATING EXPERIENCE .

A. UNIT ONE March I-9: Unit One began the reporting period in a continuation of the Maintenance Outage that began on February 28, 1981. Major items performed

'during this outage were: repaired leaking valves in the drywell ("B" feed-water check, "A" recirc pump suction, "A" recirc crosstle isolation, and head vent isolation valves), various SJAE valves, and miscellaneous valves in other systems. Due to difficulties in repairing the feedwater check valve, criticality was not achieved until 1610 on March 3 The generator was put on line at 0459 on March 4. One hour later, controi rod 34-27 (J-7) overtravelled. Subsequently, the rod was inserted and electrically disarmed.

At 0625, a turbine trip was received due to a moisture separator high level.

Rods were manually inserted to shut the reactor down. During this outage, control rod drive 34-27 was changed, repairs were effected on the moistura separator drain tank and two electromatic relief valves had now pilot valves installed.

The reactor was brought critical again on February 5, at 0950, and at 1912 the generator was put on line. Load was then increased at various rates, including a twelve hour xenon soak at 430 MWe, until load was held at 816 MWe on March 9 March 10-12: Over this three day period load was held at an average of

,

810 MWe.

March 13-16: On March 13 the circuit breaker for "A" recirc pump discharge .

valve was tripping due to an unknown cause. Therefore, at 1500 load was reduced to 200 MWe, and a dryuell entry was made at 2130. The problem was isolated to the cable inside the drywell. The cable was replaced by a temporary cable until a permanent repai r can be ef fected during the next outage. At 0445, on March 14, power was increased at various rates until a load of 817 MWe was held on March 16.

March 17-20: An average load of 819 MWe was held during this four day perloo until 2030 on March 20. At that time load was dropped at 200 MWa/

hour in preparation to trip the turbine off line.

March 21-23: On March 21, at 0040, the turbine was tripped off line.

However, the reactor remained in Hot Standby. Repairs were then rade to a leak in an EHC oil supply line. Also worked, at this time was the packing [

on the turbine stop valves. At 0610 the reactor was placed in RUN, and tha '

!

generator was placed on line at 0723. Load was increased at various rates until 815 MWe was held at 1000 on_harch 23

- _ . . .

.

-March 24-28: During this five day period an average load of 810 MW e was held, until 2310 on March 28. At that time load was dropped at 100

,

'

MWe / hour to 700 MWe.

March 29-31: At 0010 load was held at 700 MWe to perform weekly turbJne tests and bi-weekly M5iV tests. During MSIV testing, 2A MSlV drifted past its test limit, initiating a Group I isolation and resultant reactor scram.

1 The problem was investigated and a faulty limit switch on the MSIV was

'

replaced. Also replaced a thermocouple on an electromatic relief valve and an accumulator on CRD 26-35 (G-10).

The reactor was brought critical at 1731, and on March 28, at 0233, the

- generator was synchronized. Load then was increased at various rates, ending the reporting period at 660 MWe, increasing at 8 MWe/ hour.

B. UNIT TWO

-March I-3: Unit Two began the reporting period dropping load at 100 MWe/

hour. At 0230 load was held at 400 MWe and the control rod pattern was changed. At 0430 load was increased using various rates until 817 MWe was held at 1800 on March 3 March 4-14: Load was held at an average of 794 MWe over this 11 day period, with the exception of March 8. On that day the weekly turbine tests were performed resul ting in an average of 780' MWe.

. March 15-18 On March 15, at 0015, load was dropped to 160 MWe-to perform scram timing on 89' control rods. The rod sequence was also changed at that

,

time. At 1010 load uas increased untti March 18 at 0500 when a load of 800 MWe was held.

.

March 19-21: An average load of 800 MWe was held over this three day period.

i March 22-23: On March 22 load was dropped to 600 MWe to perform special rod moves for the Nuclear Engineer. Load was then increased at 5 MWe/ hour

'

until 790 MWe was achieved and held at 0100 on March 24.

March 24-31: During this eight day period, load was held at an average of 788 MWe, except on March 28. On that day, there was an average load of 773 MWe, due to the weekly turbine tests being performed. The unit ended the

,

reporting period holding a load of 796 MWe.

PLANT OR PROCEDURE CHANGES, TESTS, EXPERIMENTS, AND SAFETY RELATED

,

MAINTENANCE A. Amendments to Facility License or Technical Specifications Amendments 63 and 57 to Licenses DPR-29 and DPR-30, respectively On March 16, 1981, the NRC issued Amendment 63 to License DPR-29 and Amendment 57 to License DPR-30. These changes; (1) correct the minimum amount of diesel fire pump fuel oil in the day tank to be 150 gallons; (2) add the cable spreading room smoke detectors t.o Table 3 12-1; and (3) add the cable spreading room sprinkler system to Table 3 12-2.

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

C. Tests and Experiments Requiring NRC Approval There were no Tests and Experiments requiring NRC approval for the reporting period.

D. Corrective Maintenance of Safety Related Equipment I The following represents a tabular summary of the safety related maintenance performed on Unit One and Unit Two during the reporting period. The headings indicated in this summary include: Work 4
