CX-019463: Advanced Test Reactor Warm Waste Treatment Facility Replacement

The Advanced Test Reactor Warm Waste Treatment System has limited capability to treat radioactive wastewater. One Warm Waste Treatment Facility is out of service, while the other has only one operational exchange bed. Ion exchange handling systems that charge resin to and discharge resin from the ion exchange beds in the Warm Waste Treatment Facilities fail frequently, restricting the change-out of depleted resin bed and causing spills of radioactive resin. Diaphragm valves in the Warm Waste Treatment Facility frequently fail because of limited shelf life of rubber components. System leaks to the drain system waste thousands of gallons of clean water each month. Tanks, lines, and valves associated with no-longer-used resin regeneration functions add to the complexity and difficulty of operating the system. Radioactive monitoring portions of the system are undependable and outdated, affecting measurements associated with State of Idaho permits for operation and day-to-day discharge monitoring. Hot waste cannot be treated with present capabilities.
