- 2. 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 not 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 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 compiled by Michael J. Cialkowski, telephone number (015)357-6761, extension 2427.

OF OPERATION:
The unit remained on-line throughout most of the month. Several minor power reductions were required due to maintenance and surveillance activities. The unit experienced a reactor scram on 10/19/94 due to oscillations in the Electro Hydraulic Control system. The unit was returned to service on 10/24/94.
