摘要： Apparatus for agitating and circulating a liquid 20 comprising a vessel having two upright chambers 10, 12 and two vertically displaced ducts 14, 18 connected the chambers 10, 12. In use of the apparatus, a steady flow of gas into the top of one chamber 10 provides both an oscillation and a circulation of the liquid 20 in the apparatus, as the gas is periodically vented through the upper duct 18. The apparatus has one application in the dissolution of material from nuclear fuel pins during reprocessing.

摘要： A process for the removal of deposits consisting essentially of the oxides of one or more transition metals from a surface, which process comprises contacting the said surface at pH below 7.0 with a reagent comprising a one-electron reducing agent which is a low oxidation state transition metal ion in combination with a complexing agent which is thermally stable at a operating pH. The process is particularly suitable for decontaminating the cooling system or a component associated with the cooling system of a water-cooled nuclear reactor, or other contaminated plant items.
