Title: Late Wash Filter Demonstration Unit program plan

Technical Report ·
DOI:https://doi.org/10.2172/6690247· OSTI ID:6690247

This report details a planned a non-radioactive engineering demonstration of the DWPF Late Wash Facility (LWF) for washing salt precipitate feed, and of the In-Tank Precipitate (ITP) filters. The scale will be 0.05 to 0.1, with some larger components, prototypical instruments, and full-length filter elements. Precipitate slurry for late wash tests will be fully irradiated (3EO8 rads). Program needs and objectives are to demonstrate LWF design, optimize LWF process operations including filter cleaning and benzene sparging, test actual instruments including benzene and nitrite monitors, and test advanced design concepts such as etched filters. In addition, the Late Wash Filter Demonstration Unit (LWFDU) will support the operation and long-term improvement of ITP filtration. The expected cost of the LWFDU is $1.8 million. Operating costs in FY 1993 are expected to be $1.0 million. Testing is expected to begin 3QFY93, with LWF design confirmation and LWF operations bases completed by the end of 1QFY94.
