Abstract:
A receptacle is disclosed having an interior surrounded by a container body formed of two layers of different material. The inner layer is soluble in the presence of a selected solvent while the outer layer, which is supported by the inner layer, is formed of a material that is insoluble in the presence of the solvent. The inner layer may particularly be either hot or cold water soluble and may specifically be formed of polyvinyl alcohol. The outer layer may be in the form of frangible shell that is bonded to the inner layer and formed of a water insoluble material. The container body may further include a middle layer interposed between the inner and outer layers. A method of removing chemical residue from a container is also provided. The method comprises contacting the inner layer of the container body with sufficient quantity of water to dissolve the inner layer.
Abstract:
Films, 0.5-10 mils thick, which are rapidly and completely soluble in cold water, and which are suitable for use as packaging film in automatic packaging equipment, can be prepared by conventional melt extrusion processes when prepared from a novel composition consisting essentially of 5-20 parts by weight of a polyethylene glycol (having an average molecular weight in the range between 325 and 550) in 100 parts by weight of a partially hydrolyzed low molecular weight polyvinyl alcohol.
Abstract:
A means to contain and deliver either liquids or solids to a predefined or targeted location. This invention allows the user to target locations that are either above the ground or are below the surface of the ground and deliver either a liquid or a solid to that location.
Abstract:
Plutonium powders are stored in stainless steel canisters with stainless steel lids. The stainless steel canisters are extruded and have no interior welds. Each canister includes a vent with an integral HEPA filter. The canisters are of various capacities and nest, one within another, when not used for storage.

Abstract:
Radiological containment bags for use in storing alpha particle emitting waste are described. The radiological containment bags are formed of a multilayer film with an inner layer of the film being a sacrificial layer that lies between the interior of the bag and a structural polymeric layer. The sacrificial layer includes a flexible composite material that in turn includes a polymeric matrix and an alpha particle energy absorber incorporated in the polymeric matrix. The sacrificial layer can include a chromophore that can detect early degradation of the sacrificial material.
Abstract:
A system for breaking down medical waste for safe disposal includes a novel disposal solution for dissolving and dispersing the medical waste, as well as a hardening agent that solidifies the disposal solution to prevent it from contaminating the environment after disposal. The novel disposal solution includes a dispersion agent that dissolves the medical waste in addition to a neutralizer, which binds to the dissolved medical waste to render it inert. The disposal solution can optionally include defoaming, preservation and/or anti-freeze agents. The system may also include a vessel with a vented cap for storing the disposal solution prior to and during use. The vessel may also be used to discard the disposal solution and broken-down medical waste after the disposal solution solidifies.
Abstract:
A storage container for hazardous material, such as transuranic waste, has a stainless steel can body covered by a stainless steel lid. The can body has a locking collar welded thereto and a locking ring fastened to the lid removably mounted within the locking collar. Locking tabs on the locking ring are received beneath locking shoulders on locking collar upon rotating the locking to hold the lid closed. A U-shaped handle is pivoted on the locking ring for rotating the locking ring to lock the lid to the locking collar and thus to the can body, the U-shaped handle being further used to lift the storage container. A spring biased locking pin with a thumb operated tab is coaxial with one pintle of the U-shaped handle, the tab being squeezed toward the handle by the operators thumb to unlock the pin against the bias of a coil spring so as to allow the locking ring to rotate to an unlocked position when it is desired to remove the lid from the can body.
