System design, construction, and start-up of the Hanford transportable grout equipment facility

This paper reports on the development of a grouting process for the immobilization and final disposal of various mixed low level radioactive phosphate/sulfate wastes from the Handord N-reactor operations. The processing facility was designed using a modular concept featuring totally remote maintenance capability where necessary. The unit is capable of processing waste with activity levels up to 1.75 Ci/liter. The modules were fabricated and assembled off-site and transported to the Hanford site where they were installed in the prepared site. The units were then electrically and mechanically interconnected prior to testing
