A container for the consolidation of waste materials including radioactive containing waste, and a method of consolidating such materials. The container comprises an outer cylinder and an inner cylinder comprising internal compression plates that are designed to resist collapse during consolidation, and therefore control the size of the consolidated container to a predictable shape and dimension. The container is sufficient to hold a variety of materials, including hazardous, toxic, or radioactive waste, and the container is configured to hold such waste without releasing it to the environment.

The present invention provides systems, methods and devices for storing and/or disposing of hazardous waste material such as calcined material. In certain embodiments, the system comprises a filling nozzle having a valve body having a distal end and an outer surface, the outer surface proximate the distal end being configured to sealingly and removeably couple to an inner surface of a filling port of the container. In certain embodiments, the method comprises (a) coupling an outer surface of a filling nozzle with an inner surface of a filling port of a container to form a first seal (b) adding hazardous waste material into the container (c) decoupling the filling port from the filling nozzle and (d) inserting a fill plug into the filling port, the fill plug forming a second seal with the inner surface of the filling port, the second seal being distally spaced from at least a portion of the first seal with respect to the container.

Steel and/or copper spherical capsules are specifically engineered and manufactured for housing uranium waste products. The uranium waste products are placed within the spherical capsules. Human-made cavern(s) and/or substantially lateral wellbore(s) are constructed for receiving the uranium waste containing spherical capsules. The human-made cavern(s) and/or the substantially lateral wellbore(s) are deeply located in specific types of geologic rock formations thousands of feet below the Earth's surface. These uranium waste containing spherical capsules are loaded from the Earth's surface into the human-made cavern(s) and/or into the substantially lateral wellbore(s). The emplaced spherical capsules are surrounded by an immersive protective medium within the given human-made cavern(s) and/or within the substantially lateral wellbore(s). The given human-made cavern(s) and/or the given substantially lateral wellbore(s), with the uranium waste containing spherical capsules, are sealed off.

A system for preparing a container holding radioactive waste for dry storage. In one aspect, the invention can be a system for preparing a container having a cavity loaded with radioactive elements for dry storage, the system comprising: a gas circulation system comprising a condenser module, a desiccant module, and a gas circulator module; the gas circulation system configured to form a hermetically sealed closed-loop path when operably connected to the cavity of the container; and means for adding and removing the desiccant module as part of the hermetically sealed closed-loop path.

An impact amelioration system for nuclear fuel storage components in one embodiment includes a fuel storage canister and outer cask receiving the canister. The canister is configured for storing spent nuclear fuel or other high level radioactive waste. A plurality of impact limiter assemblies are disposed on the bottom closure plate of the cask at the canister interface. Each impact limiter assembly comprises an impact limiter plug frictionally engaged with a corresponding plug hole formed in the cask closure plate. The canister rests on tops of the plugs, which may protrude upwards beyond the top surface of the bottom closure lid. The plugs and holes may mating tapered and frictionally engaged surfaces. During a cask drop event, the canister drives the plugs deeper into the plug holes and elastoplastically deform to dissipate the kinetic impact energy and protect the structural integrity of the canister and its contents.

The invention provides a containment structure, the containment structure comprising a vessel with an upwardly facing opening defining a periphery; a lid in rotatable and slidable communication with the periphery; and a plurality of rods contained within the lid and in slidable communication with the periphery. Also provided is a method for sealing and unsealing a containment vessel defining a body with a longitudinal axis and a lid, the method comprising simultaneously moving the lid parallel to the longitudinal axis and orthogonal to the longitudinal axis.
