Abstract: As shown in FIGS. 8 and 9, the instant invention provides a concave filter 530 which comprises two oppositely disposed geotextile fabric sheets 560A and 560B. Fabric sheets 560A and 560B are porous for filtering the liquid from the slurry solids and may be fabricated from a geotextile material such as the material composing filter sheets 330a and 330b (see FIG. 4). Disposed between fabric sheets 560A and 560B is at least one drainage grid 350 such as the drainage grid 350 illustrated in FIGS. 4 and 4A.

Abstract: Apparatus and method for dewatering radioactive waste slurry solids. The apparatus includes a vacuum pump for applying a vacuum to a suitable flexible filter and collapsible membrane combination in which the slurry solids are contained so that the slurry solids are compressively dewatered when the vacuum is applied. The apparatus further includes a container for suitably storing the resulting dewatered slurry solids.

Abstract: An improved tie-down assembly for connecting a transportation cask containing radioactive wastes to the trailer of a tractor-trailer as disclosed herein. Each of the lugs is characterized by a flat profile and is formed from steel which is less ductile than the steel forming the walls of the cask, yet having an ultimate stress which is higher than the ultimate stress of the steel forming the cask walls. Additionally, each of the lugs includes a reinforcing plate having substantially the same shape as the contour of the cask walls, as well as an elongated, flat lug member that terminates in an eyelet for attaching the lug member to a tensioned cable. The lower ductility of the lugs, coupled with the extremely flat profile made possible by the higher ultimate stress of the material that forms them, minimizes the moment forces that the tensioned cables apply to the cask walls, and minimizes the chance that the lugs will apply a rupturing or breaking force onto the cask walls in the event of a severe accident.
