Abstract:
Apparatus for filtering particulate matter from a fluid flow pumped from a coolant pool of a nuclear reactor, comprising:a normally sealed vessel defining an interior chamber;a rigid turntable structure means for rotatably mounting the turntable structure on a central axis in the chamber and having means therewith stationarily supporting thereon a plurality of disposable filter cartridges in spaced-apart parallel relation to each other;fluid conduit means including a linear section extending centrally into the chamber and having an inlet in sealed connection therewith for conducting fluid to be filtered from a point outside the vessel and downwardly through the linear section;manifold means within the chamber for receiving a fluid flow from the linear section and directing it to the filter cartridges;first normally closed gate means mounted on the vessel permitting selective extension of a turntable manipulating tool therethrough for manually rotating the structure to thereby advance the filter cartridges on the structure through successive operative positions within the chamber;second normally closed gate means on the vessel to permit selective insertion of a filter manipulating tool into the chamber; andthird normally closed gate means on the vessel to permit installation of filter cartridges into the chamber and onto the turntable and expulsion of contaminated filter cartridges from the vessel.
