CX-020888: TRA-671 Secondary Cooling Water Chemical Addition System

The proposed action replaces the chemical storage tanks, pumps, and controllers for the sodium hypochlorite chemical addition system within the cooling water system in building Test Reactor Area (TRA)-671. The purpose of the proposed action is to improve the chemical addition process and reduce the amount of emissions that result from chemical transportation and delivery. The chemical addition system’s function is to control algae growth and corrosion in the secondary coolant system, and the proposed action will improve the chemical addition process by streamlining the delivery, storage, and handling of chemicals used.
