Abstract: A cured resin system is used to encapsulate certain liquid low level radioactive wastes which are solvents for or are soluble in the uncured resin and which are more soluble in water than in the uncured resin. The process comprises the dilution of said waste with water to an extent that the amount of waste that will partition in the uncured resin system is less than the amount that will retard the cure rate of the system or that will adversely affect physical properties of the cured product, followed by the uniform dispersion of the aqueous solution in said curable resin system after which the resin system is cured to a solid with the aqueous waste solution dispersed therein.

Abstract: A method for sequestering radioactive waste materials against dissolution and migration into the biosphere during prolonged storage is disclosed. The method comprises incorporating the waste materials as oxides into a mass of molten glass, and subsequently casting the homogeneous molten mass in an inert chemically durable glass container supported by a mold. The container is then sealed and permitted to cool, thereby forming a solid mass having an outer layer or cladding of non-radioactive glass. The glass used for the container preferably is a leach resistant soda-lime-alumina-silica glass similar to conventional bottle glass, and the coefficient of expansion thereof should be sufficiently close to that of the contents to avoid excessive stress at the interface upon cooling.

Abstract: An organic ion exchange material, which comprises a mixture of grains of a first type bearing groups containing exchangeable hydrogen ions and grains of a second type bearing groups containing exchangeable hydroxyl ions and which has been used in a cleaning circuit in a nuclear reactor, is subjected to a treatment before the ion exchange material is further processed for final storage of the radioactive waste products contained therein. The treatment comprises removing hydrogen ions and/or hydroxyl ions or groups containing hydrogen ions and/or groups containing hydroxyl ions from the grains, whereafter the grains of the first type are separated from the grains of the second type, before the grains of each type are further processed separately for final storage of the radioactive waste products contained therein.

Abstract: A regenerative heat exchange apparatus for use with a hydrogen storing material is presented. The apparatus includes a regenerator chamber packed with a heat storing material, and the regenerator chamber is disposed in between a high temperature fluid pathway and a low temperature fluid pathway of a heat exchanger.

Abstract: A high solids content explosive charge is formed by placing the dry solids uch as RDX in a mold, adding TNT over the dry solids and holding the interior of the mold at an elevated temperature and reduced pressure to permit diffusion of the liquid TNT through the solids while the vacuum enhances the discharge of air from the mass. In one embodiment, a casing and liner of a shaped-charge warhead is employed for the mold and the TNT is placed in a funnel atop the casing. This assembly is placed inside a heated evacuated chamber for long enough to permit the liquid TNT to diffuse through the solid particles and for air to be discharged. In other embodiments, an air-tight casing is employed whose interior is evacuated while heating is performed.
