1. INTRODUCTION The LaSalle County Nuclear Power Station is a two-unit facility owned by Commonwealth Edison Company and located near Marseilles, Illinois. Each unit is a Bolling Water Reactor with a designed net electrical output of 1078 Megawatts. Waste heat is rejected to a man-made cooling pond using the Illinois River for make-up and blowdown. The architect-engineer was Sargent and Lundy and the primary construction cont'ractor was  ;

Commonwealth-Edison Company.

Unit One was issued operating Ilcense number NTF-11 on April 17, 1982.

Initial criticality was achieved on June 21, 1982 and commercial power operation was co;mmenced on January 1, 1984.

This report was compiled by John W. Thunstedt, telephone number (815)357-6761, extension 2463.

SUMMARY

CT OPERATING EXPERIENCE pny Ilmg Event 1 000C Reactor critical, generator on-line, full power (Note Almost daily, power reductions were performed due to system load conditions or to improve main condenser vacuum which resulted from high cooling lake temperature; these reductions greater than 20% are reported in Section II.D.3. The following items summarize other conditions).

6 0000 Reduced power to 2884 NWT for TIP set.

7 1200 Returned to full power.

14 0300 Reduced power to 2983 MWT due to a blown diaphram on rod 26.39 drive system.

1200 Returned to full power.

! 15 0200 Reduced load to 2080 MWT due to scram-time testing and rod pattern adjustment.

2000 Returned to full power.

17 1400 Reduced load to 2601 MWT due to hydrogen leak on main generator.

18 1100 Returned to full power.

19 0000 Reduced load to 3130 MWT for CRD exercising.

28 0500 Reduced load to 3200 MWT due to Xenon transient.

31 0300 Reduced load to 2580 MWT due to hydrogen venting.

1300 Returned to full power.
