INTRODUCTION a

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 primary construction

. contractor was commonwealth Edison Company.

1 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.

UNIT ONE M-1-0-85-008 This Modification provided access to various fire dampers that are not accessable per the August, 19d4, technical basis of the LaSalle County Station Fire Damper Surveillance program. There were no unreviewed safety questions.

M-J-0-85-011 This Modification was to install the interconnections required for the interim Redwaste Storage Facility telephone connection, paging connection, fire detection alarm connection, and the potentially contaminated sump high level alarm connection. There were no unreviewed safety questions.

M-1-0-86-023 This Modification was to improve the exiting method of sampling the flow in the Mid/Hi Range portio of the Stadnby Gas Treatment Wide Range Gas Monitor (WRGM). This change will minimize the amount of iodine plateout in the sample line. There were no unreviewed safety questions.
