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 viectrical' output of 1078 Negawatts.

Maste 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 contractor was=

Commonwealth Edison Company.

Unit One was issued operating Ilcense number NIT-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 compiled by Michael J.

INTRODUCTION (Unit 2)

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 Hater Reactor with a designed net electrical output of 1078 Hegawatts. Haste 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 contractor was Consonwealth Edison Company.

Unit Two was issued operating license number NPF-18 on December 16, 1983. Initial criticality was achieved on March 10, 1984 and commercial power operation was commenced on June 19, 1984.
