Abstract

Radioactive alkali metal is mixed with particulate silica in a rotary drum reactor in which the alkali metal is converted to the monoxide during rotation of the reactor to produce particulate silica coated with the alkali metal monoxide suitable as a feed material to make a glass for storing radioactive material. Silica particles, the majority of which pass through a 95 mesh screen or preferably through a 200 mesh screen, are employed in this process, and the preferred weight ratio of silica to alkali metal is 7 to 1 in order to produce a feed material for the final glass product having a silica to alkali metal monoxide ratio of about 5 to 1.

Apparatus and process for handling dangerous fluent material. [Radioactive waste handling, disposal, and storage]

Patent Stock, A.J.; Christofer, D.E.; Brinza, J.E.

Systems, apparatus and methods are disclosed for disposing of radioactive waste materials by placing them into a container such as a steel drum, together with cement or other solidifying agent and water or other suitable liquid in amounts sufficient to provide eventually a solidified mixture of predetermined amounts of cement or other solidifying agent and radioactive material, closing the drum, agitating the mixture in the drum for mixing the contents, and then storing the drum for at least a period of time sufficient to permit partial decay of radioactive materials or to await available time for shipment. Also disclosed aremore »« less
METHOD OF HANDLING RADIOACTIVE WASTE SOLUTIONS

Patent

A method is reported for converting aqueous radioactive aluminum nitrate solutions into solids. This is accomplished by using a fluidized bed of Al/sub 2/ O/sub 3/ particles in which Al(NO/sub 3/)/sub 3/ waste is sprayed, heating the bed to approximately 500 deg C, and removing Al/sub 2/O/sub 3/ containing radioactive material from the bottom of the bed.

System for handling and storing radioactive waste

Patent Anderson, J.K.; Lindemann, P.E.

A system and method for handling and storing spent reactor fuel and other solid radioactive waste is claimed, including canisters to contain the elements of solid waste, storage racks to hold a plurality of such canisters, storage bays to store these racks in isolation by means of shielded doors in the bays. This system also includes means for remotely positioning the racks in the bays and an access tunnel within which the remotely operated means is located to position a rack in a selected bay. The modular type of these bays will facilitate the construction of additional bays and accessmore » tunnel extension.« less
