Cigar Lake Freeze Plant

Alliance Energy’s work included the disconnection and relocation of a modular freeze plant which consisted of five 1000 HP 4160V motors complete with enclosures, 5 condenser skids, 1 electrical building, a brine tank and three 75 HP motors on the brine pump skid.

This equipment was originally built for the Mosaic K3 mine site and was purchased by Cameco, decommissioned and relocated to Cigar Lake for reassembly. The project was changed from a lump sum bid to a T&M project due to engineering issues. We successfully completed the project on schedule and under budget.
