This test plan describes the Phase II testing program of the Hanford Waste End Effector (HWEE) at the Washington River Protection Solutions (WRPS) Cold Test Facility (CTF) using a Pacific Northwest National Laboratory (PNNL)-designed testing setup. This task builds on Phase I development testing completed in August 2017 and reported in PNNL-26856 to address some key actual tank waste challenges. The task includes demonstrating retrieval of a mixed layered simulant and retrieval of uneven simulant profiles like that found near tank walls. A separate demonstration using only the HWEE conveyance jet pump will start to assess the lifting capabilities of this device for transporting waste out of an underground tank. The PNNL-designed robotic gantry system and associated systems (e.g., tanks, high-pressure water delivery and valves, instruments, etc.) used at CTF during Phase I have been modified and upgraded to implement the Phase II test program and measure various process parameters. The tests will involve retrieval of water and kaolin (sludge) simulant to determine pumping rate, dilution factors, and screen fouling rate.
