Tank closure cesium removal

Номер: US20180033508A1
Автор: Gregory B. Harting, Mark A. Beck, Thomas J. Gammon
Принадлежит: Westinghouse Electric Co LLC

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.

An object of the invention is to reliably prevent the precipitation of scale during a reclamation step in a deionization treatment. A water reclamation system and a deionization treatment device of the present invention each comprises a deionization section, a supply section which supplies a scale inhibitor to a water to be treated, and a control section. The control section acquires a supply start time and a supply stop time for at least one of the scale inhibitor and a low ion concentration water based on the concentration of a scale component in the deionization section, and causes the supply section to supply at least one of the scale inhibitor and the low ion concentration water in the interval between the supply start time and the supply stop time. 1. A water reclamation system , comprising:a deionization section which comprises a pair of opposing electrodes that are charged with opposite polarities, an inter-electrode flow channel positioned between the electrodes and through which a water to be treated containing ions can flow, and ion exchange membranes disposed on the inter-electrode flow channel side of each of the electrodes, the deionization section performing a deionization treatment in which the ions are adsorbed to the electrodes and a reclamation treatment in which the ions are desorbed from the electrodes,a treated water discharge channel which is positioned downstream from the deionization section and discharges, from the deionization section, a treated water from which the ions have been removed during the deionization treatment,a concentrated water discharge channel which is positioned downstream from the deionization section and discharges, from the deionization section, a concentrated water which contains the ions desorbed from the electrodes during the reclamation treatment,a supply section which supplies, to the deionization section, at least one of a scale inhibitor and a low ion concentration water which has a lower concentration than the ...
