摘要： The invention relates to systems, apparatus and methods for the removal of cesium and other radionuclides from liquid waste contained in a high level waste tank. The invention includes transporting a stream of the liquid waste from the high level waste tank to one or more ion-exchange column assemblies to remove the cesium therefrom using a sorbent, such as, crystalline silico-titanate. The ion-exchange column assemblies include an ion-exchange column and an integrated shield. The column is concentrically positioned within the shield and an air gap is present between the column and the shield to provide passive cooling.

摘要： A mobile radiation system is provided. The mobile radiation system comprises a mobile radiation device coupled to a control unit; a radiation blocker having an adaptor opening for receiving said mobile radiation device when said mobile radiation device is in a seated position on said radiation blocker; and a mobile carrier comprising a first compartment for housing said radiation blocker, a second compartment for housing said control unit, and a carrier motion device. The adaptor opening can dimensionally fit the mobile radiation device to block radiations from the mobile radiation device when said mobile radiation device is in the seated position. The mobile radiation device can produce radiation having peak radiation wavelength in a range of from about 250 nm to about 450 nm and can have a peak irradiation power in a range of from about 0.5 W/cm2 to about 10 W/cm2.

摘要： A system for storing and/or transporting high level radioactive waste, and a method of manufacturing the same. In one aspect, the invention is a ventilated vertical overpack (“VVO”) having specially designed inlet ducts that refract radiation back into the storage cavity. A clear line-of-sight does not exist through the inlet ducts and, thus, the canister can be supported on the floor of the VVO. Also disclosed is a method of manufacturing a variable height VVO that falls within a regulatory license previously obtained for a shorter and taller version of the VVO.
