I. INTRODUCTION The LaSalle Nuclear Power Station is a Two Unit Facility Located in Marseilles. Illinois. Each Unit is a Boiling Water Reactor with a designed electrical output of 1078 MWe set. The Station is owned by Commonwealth Edison Company. The Architect / Engineer was Sargent & Lundy, and the primary construction contractor was Commonwealth Edison Company.
The condenser cooling nothod is a closed cycle cooling pond. Unit One is subject to License Numbcr NPF-11, issued on April 17, 1982. The date of initial criticality was June 21, 1982. The unit commenced commercial generation of power on January 1, 1984. Unit Two is subject to license number NFP-18, issued on December 16, 1983. The date of initial criticality was March 10, 1984. The Unit is expected to commence coasmercial generation of power in August, '84.
This report was compiled by Aras R. Lintakas telephone number (815)357-6761, extension 324.

These figures will be used to plot a graph for each reporting month. Note that when maximum dependable capacity is used for the net electrical rating of the unit there may be occasions when the daily average power level exceeds the 100% line (or the restricted power level line.) In such cases the average daily unit power output sheet should be footnoted to explain the apparent anomaly.
