A compression member for insertion into a pig for transporting a container of biohazardous materials includes a flange maintained in spaced relation with an annulus by pillars; and spaced apart pivotable grip components supported by the annulus and extending downwards from the annulus between respective ones of the pillars towards, but not into contact with, the flange, the pivotable grip components resiliently compressible inwardly against the container when the container is received within the compression member. In use, the compression member receives at least a closure portion of the container and, in turn, is itself received within a complementary annulus of the pig. When being received within the complementary annulus of the pig, the pivotable grip components are urged inwards towards the container thereby to grip the container and provide a spacer for between this portion of the container and the pig.

An underground ventilated system for storing nuclear waste materials. The system includes a storage module having an outer shell defining an internal cavity and an inner shell. A majority of the height of the outer shell may be disposed below grade. The outer shell may include a hermetically sealed bottom. First and second canisters are positioned in lower and upper portions within the cavity respectively in vertically stacked relationship. A centering and spacing ring assembly is interspersed between the first and second canisters to transfer the weight of the upper second canister to the lower first canister. The assembly may include centering lugs which laterally restrain the first and second canisters in case of a seismic event. A natural convection driven ventilated air system cools the canisters to remove residual decay heat to the atmosphere. In one non-limiting embodiment, the shells are made of steel.

A method of packaging a radioactive waste including the steps of: (a) providing a containment enclosure having (i) an outer polymeric fabric layer and (ii) an inner polymeric fabric layer, wherein the outer and inner polymeric fabric layers are thermally stable to −40° F.; (b) placing a radioactive waste within the inner polymeric fabric layer; and (c) closing an outer closeable flap on the outer polymeric fabric layer.

A nuclear waste cask with impact protection includes impact limiters comprising deformable energy-absorbing perforated sleeves. An impact amelioration system for nuclear fuel storage components includes impact limiter assemblies at the bottom cask to canister interface including impact limiter plugs frictionally engaging corresponding plug holes formed in the cask closure plate. A nuclear waste fuel storage system includes an unventilated cask including a heavy free-floating radiation shielding lid loosely coupled the top end of the cask in a movable manner via the anchor bosses which provides cask over pressurization protection. A nuclear waste cask includes an axially elongated rectangular cuboid cask body having a cavity for holding nuclear waste materials and cask locking mechanism including first locking protrusions on the lid which are selectively interlockable with mating second locking protrusions on the cask body to lock the lid to the cask body.

A system for the storage of a radioactive waste product, wherein the radioactive waste product is located in a container and where one or more containers are stored in a bore hole drilled beneath a surface and having a bottom, wherein following placement of the one or more containers in the bore hole closer to the bottom, a fluid is added to the bore hole to a height above the upper most container, and wherein an upper cover is located above the upper most container and above the fluid to seal in the one or more containers and a non-permeable material is placed above the upper cover, a container storage area being formed within the bore hole beneath the upper cover.

A shipping container comprises a tubular or cylindrical shell having a closed end and an open end, a top end-cap removably secured to the open end of the tubular or cylindrical shell, and at least one fuel assembly compartment defined inside the shell. Each fuel assembly compartment includes elastomeric sidewalls and is sized and shaped to receive an unirradiated nuclear fuel assembly through the open end of the shell. The shipping container may further include a divider component, for example having a cross-shaped cross-section with ends of the cross secured to inner walls of the shell, and the divider component and the inner walls of the shell define the fuel assembly compartments. To load, the shipping container is arranged vertically and an unirradiated nuclear fuel assembly is loaded through the open end of the shell into each compartment, after which the open end is closed off by securing the top end-cap.

A system and method for removing spent fuel assemblies from a fuel building and transporting them to on-site facilities. A cask transporter is moved into the fuel building with an empty spent fuel storage cask, spent fuel assemblies are loaded into spent fuel storage cask, the cask is sealed, and the cask transporter moves the loaded spent fuel storage cask to a handling area for final disposal. Components of the system include a penetration cover, a lifting mechanism, a control system, a valve system, and the cask transporter.

A device for transferring a toxic substance from a dispensing vessel to at least one receiving vessel comprising: (i) a receiving portion arranged to receive a dispensing vessel containing a toxic substance; and (ii) a transfer apparatus having a first infusion line adapted for fluid communication with the dispensing vessel to transfer a carrier fluid into said vessel and a second infusion line having one end adapted for fluid communication to withdraw and transfer the carrier fluid and the toxic substance from the dispensing vessel and the other end of the second infusion line arranged to connect with the at least one receiving vessel.
