i I. . INTRODUCTION (UNIT-1).

The LaSalle County" Nuclear Power. Station is a.two-Unit facility owned by commonwealth Edison company and located near Marsellies, Illinois.

Each unit is a Boiling Water Reactor with a designed not electrical.

output of.1078 Negawatts. 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 contractor was Commonwealth. Edison Company.

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

This report was complied by Nichael J. Cialkowski, telephone number (815)357-6761, extension.2427.
