The fluorine generating plant (K-1300) generated, bottled and stored fluorine. It had not been in great demand before the war, and Kellex and the Manhattan District considered four different processes for large-scale production. A process developed by the Hooker Chemical Company was chosen. Owing to the hazardous nature of fluorine, it was decided that shipping it across the United States was inadvisable, and it should be manufactured on site at the Clinton Engineer Works. Two pump houses (K-801 and K-802) and two cooling towers (H-801 and H-802) provided of cooling water per day for the motors and compressors.
