I. INTRODUCTION (UNIT 1)

The LaSalle County Nuclear Power Station is a two-Unit facility owned by comanonwealth Edison Company and located near Marseilles, Illinois. Each unit is a Boiling Water Reactor with a designed not electrical output of 1078 Megawatts. Waste heat is rejected to a man-nade cooling pond using the Illinois river for make-up and blowdown. The architect-engineer was sargent and Lundy and the contractor was Comanonwealth Edison Company.

Unit one was issued operating license number NPF-11 on April 17, 1902. Initial criticality was achieved on June 21, 1982 and cosamercial power operation was comunenced on January 1,1984.

This report was compiled by Michael J. Cialkowski, telephone nunpber (015)357-6761, extension 2056.
