Abstract
A filtration system for concentrating radioactive debris particulate provides efficient filtration, concentration and transport to collection canisters of radioactive particles from a refueling cavity, spent fuel pool, or other water volume where small particles must be removed from the water. The system includes a flushing pump module that draws contaminated water from a cut zone enclosure. The flushing pump module has a separator that removes large size particulate from the contaminated water. A solid media filter module receives the contaminated water from the flushing pump module and removes medium size particulate from the contaminated water. The solid media filter module has a structure for ejecting the medium size particulate and passing the ejected particulate to a concentrate handling module having a purge tank and a slurry transfer pump. A disposal canister station receives the medium size particulate from the slurry transfer pump and fills disposal canisters for transport and storage. A cartridge filter module having multiple stages of cartridge filters for removing small size particulate receives a flushing flow of water from the solid media filter module. The filtered water is returned from the disposal canister station and from the cartridge filter module back into the cut zone enclosure to provide a closed-loop filtration system.
