I. INTRODUCTION The LaSalle Nuclear Power Station is a Two Unit Facility Located in Marseilles, Illinois. Each Unit is a Boiling Water Reactor with a designed electrical output of 1078 MWe net. The Station is owned by Commonwealth Edison Company. The Architect / Engineer was Sargent & Lundy, and the primary construction contractor was Commonwealth Edison Company.

The condenser cooling method is a closed cycle cooling pond. Unit One is subject to License Number NPF-11, issued on April 17, 1982. The date of initial

(

criticality was June 21, 1982. The unit commenced commercial generation of power on January 1, 1984.

Unit Two is subject to license number NFP-18, issued 3

on December 16, 1983. The date of initial criticality was March 10, 1984. The Unit is expected to commence commercial generation of power in August, '84.

This report was compiled by Randy S. Dus, telephone

- _ number (815)357-6761, extension 324.

SUMMARY

OF OPERATING EXPERIENCE FOR UNIT ONE l

MARCH 1-5 The Unit started the reporting period in cold shutdown due to repairs on the extraction steam line expansion bellows and the condenser boot seal.

MARCH 6-18 The reactor went critical at 2240 hours0.0259 days 0.622 hours 0.0037 weeks 8.5232e-4 months on March 6. At 1235 hours0.0143 days 0.343 hours 0.00204 weeks 4.699175e-4 months on March 7 the main generator was synchronized to the grid. At 1508 hours0.0175 days 0.419 hours 0.00249 weeks 5.73794e-4 months on March 7 reactor power was at 25%. At 2130 hours0.0247 days 0.592 hours 0.00352 weeks 8.10465e-4 months on March 7 a Rx shutdown was commenced to analyze stress loading of temporary ventilation ductwork in drywell. At 0050 hours5.787037e-4 days 0.0139 hours 8.267196e-5 weeks 1.9025e-5 months on March 8 the turbine generator was tripped. At 0640 on March 8, the Rx was shutdown. The reactor was critical for 32 hours3.703704e-4 days 0.00889 hours 5.291005e-5 weeks 1.2176e-5 months and 0 minutes.

MARCH 19-31 The reactor went critical at 0315 hours0.00365 days 0.0875 hours 5.208333e-4 weeks 1.198575e-4 months on March 19. At 2335 hours0.027 days 0.649 hours 0.00386 weeks 8.884675e-4 months on March 19, the main generator was synchronized to the Grid. Reactor power was raised to 23% at 1730 hours0.02 days 0.481 hours 0.00286 weeks 6.58265e-4 months on March 20. At 2200 hours0.0255 days 0.611 hours 0.00364 weeks 8.371e-4 months on March 20, reactor power was raised to 44%. At 0700 hours0.0081 days 0.194 hours 0.00116 weeks 2.6635e-4 months on March 21, reactor power was 8.ncreased to 64%.

Reactor power was reduced to 39% at 1330 hours0.0154 days 0.369 hours 0.0022 weeks 5.06065e-4 months on March 22 for a drywell entry to investigate the source of water in the "B" Ex recirc motor cm.ing. At 0700 hours0.0081 days 0.194 hours 0.00116 weeks 2.6635e-4 months on March 24, reactor power was increased to 67%.

Reactor power was decreased to 47% at 1645 hours0.019 days 0.457 hours 0.00272 weeks 6.259225e-4 months on March 27 due to a feedwater heater string isolation. At 1150 hours0.0133 days 0.319 hours 0.0019 weeks 4.37575e-4 months on March 28, reactor power was reduced to 23%

due to additional feedwater heater problems. At 1720 hours0.0199 days 0.478 hours 0.00284 weeks 6.5446e-4 months on March 29, commenced pulling rods to increase power. At 0700 hours0.0081 days 0.194 hours 0.00116 weeks 2.6635e-4 months on March 30, reactor power was at 70%. The reactor was critecal for 308 hours0.00356 days 0.0856 hours 5.092593e-4 weeks 1.17194e-4 months and 45 minutes.

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

1. Amendments to Facility License or Technical Specifications.

Amendment No. 16- This amendment revised the electrical power systems Technical Specification 3.8.1.1. The Amendment changes the LaSalle Unit One Technical Specification Requirements for fast starts on the Diesel Generators, consistent with the provisions of the LaSalle Unit Two Technical Specifications.

4 This involves the reduction in the number of required fast, cold start surveillances.

i

2. Facility or Procedure Changes Requiring NRC Approval.

There were no facility or procedure changes requiring NRC approval during the reporting period.

3. Tests and Experiments Requiring NRC Approval.

There were no tests or experiments requiring NRC approval during the reporting period.

4. Corrective Maintenance of Safety Related Equipment.

The following tables present a summary of safety-related i'

maintenance completed on Unit One during the reported period.
