.l I. INTRODUCTION (UNIT 1) .

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 Boiling 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 contractor was i Commonwealth Edison Company.

Unit one was issued operating license number NPF-11 on April 17, .l 1982. Initial criticality was achieved on June 21, 1982 and  !

commercial power operation was commenced on January 1, 1984. '
