  • METHOD FOR CONDITIONING A WASTE SOLUTION CONTAINING ORGANIC SUBSTANCES AND METALS IN IONIC FORM, OBTAINED DURING WET-CHEMICAL CLEANING OF CONVENTIONAL OR NUCLEAR PLANTS
    Publication number: 20100288707
    Abstract: A method is provided for conditioning a waste solution obtained during the wet-chemical cleaning of conventional or nuclear plants and containing organic substances and metals in ionic form. At least a portion of the organic substance is degraded by electrochemical treatment or UV radiation of the waste solution, at least one metal precipitates by the addition of phosphoric acid and a resultant phosphate precipitate is removed from the waste solution.

  • Method of cleaning a steam generator of a pressurized water reactor
    Publication number: 20050126587
    Abstract: A method for cleaning steam generating devices of a pressurized water reactor treats the devices on their secondary sides at high pressure and high temperature. An aqueous cleaning solution is employed with EDTA, a reducing agent, and an alkalizing agent. Morpholine is used as the alkalization agent. A molar morpholine-concentration, which is at least as great as the molar concentration of EDTA, is selected. Hydrazine and/or formaldehyde are/is used as the reducing agent at a ratio to EDTA between 1:6 and 1:1.
