摘要： A process for the treatment of material which is or is suspected to be contaminated with one or more actinides or compounds thereof, which process includes contacting the said material with a liquid medium which comprises an aqueous solution which is free of heavy metal ions (prior to use thereof) and comprises ingredients which are naturally degradable to non-toxic products with or without mild physical assistance such as heat or ultra-violet radiation, said solution comprising:(a) carbonated water;(b) a conditioning agent; and(c) a complexing agent which comprises the anion of a carboxylic acid having from 2 to 6 carbon atoms;wherein the said process is for treatment of solid organic wastes which are or are suspected to be contaminated with plutonium or compounds thereof with or without other hazardous contaminants and includes the steps of shredding the organic waste material, intimately mixing the shredded waste material with the said liquid medium thereby dissolving contaminants as complexes in said liquid medium and separating the said liquid medium from the shredded waste material thereby reducing the radioactivity level of the organic waste material.

摘要： A method for segregating fines from the clean coarse fraction of the soil, preparing the contaminated fines for subsequent processing, and then separating the contaminants from the clean fines. The process produces a small, highly concentrated contaminanth fraction and a large fraction of clean soil. Metals, metallic compounds, and/or radioactive contaminants are removed from the fine fraction using either gravity separation, multistage gravity separation, a centrifugal jig, regular magnetic or paramagnetic separation using a high gradient magnetic separator, and/or a superconducting separator. Preparation of the fines requires selective segregation of the targeted particles size range and the removal of interfering soil fractions, and vegetation such as root hairs. This preparation is accomplished by a combination of attrition scrubbing, countercurrent jigging, and screening.

摘要： The activated elements (4) comprise two constituents having different magnetic characteristics. The first constituent has high activity and the second constituent substantially lower activity. The activated elements (4) are ground to obtain unit fragments, each consisting mainly of the first or of the second constituent. The fragments consisting of the first constituent are separated and sent towards a first discharge and storage station (18, 19, 20), and the fragments consisting mainly of the second constituent are separated and sent towards a conveyor (21). Detection of fragments of the first constituent is carried out on the conveyor, and the fragments deposited on the conveyor (21) are removed to the second discharge and packaging station (24, 25, 26) in the event that fragments of the first constituent are not detected on the conveyor (21).

摘要： The irradiated component (1) comprises at least one tubular wall with its axis vertical and fastened inside a well (2) in a concrete structure (3). The connecting elements between the concrete structure (3) and the component (1) are destroyed, the component (1) is displaced in successive steps in the vertical direction along its axis on the inside of the well (2), and the wall of the component is cut, so as to obtain blocks (26) of irradiated material of the wall, at the upper level of the well (2) of the concrete structure (3) after each displacement of the component (1). The cut blocks (26) are disposed of for the purpose of elimination or storage. The displacement of the component can be obtained by a pull or push on its lower bottom.

摘要： An ultrasonic cleaning apparatus and method is provided for a venturi flow nozzle which is mounted in a pipe having fluid flowing therethrough. The apparatus includes a plurality of ultrasonic transducers mounted in openings provided upstream of the venturi flow nozzle inlet. The transducers transmit ultrasonic waves directly into and thereby excite the fluid flowing through the venturi flow nozzle and create cavitation which cleans the nozzle. Additional transducers are preferably provided in the throat area of the venturi flow nozzle. In alternative embodiments, the transducers are mounted in high and low pressure taps associated with the venturi flow nozzle such that the transducers directly transmit ultrasonic waves into fluid flowing into the high and low pressure taps. The transducers may be mounted flush with the interior of the pipe or venturi flow nozzle, or the transducers may be mounted at a position spaced therefrom in the high and low pressure tap piping.
