l I. INTRODUCTION ,
The LaSalle Nuclear Power Station Unit One is a Boiling Water Reactor ,
- with a designed electrical output of 1078 MWe net, located in Marseilles, .
Illinois. The Station is owned by Commonwealth Edison Company. The-Architect / Engineer was Sargent & Lundy, and the primary construction contractor was Commonwealth Edison Company.
i The condenser cooling method is a closed cycle cooling pond. The plant is subject to License Number NPF-11, issued on April 17, 1982. The date ,
of initial' criticality was June 21, 1982. The unit has not commenced ,
commercial generation of power.
