Contaminated wash water in nuclear plants are processed by mixing the wash waters with ion exchange resins to form a suspension and then feeding the resulting suspension to a filter.

Method and apparatus for processing contaminated wash water

In a catalytic converter which has a housing, gas inlet and outlet nipples in the housing, a screen positioned in and held by said housing for supporting a loose catalyst material thereon and a free space provided in the housing above the loose catalyst material, there is provided a flow-directing device for guiding a stream, after its introduction into the housing through the gas inlet nipple, onto the loose catalyst uniformly and vertically from above.

A method for treating waste gases containing radioactive contamination, particularly krypton and xenon nuclides. The waste gas stream to be decontaminated is initially conducted through an enrichment system wherein the waste gas stream is divided into at least two partial streams one of which is substantially free from the radioactive impurities and constitutes the poor gas fraction and another of which constitutes the rich gas fraction. The poor gas fraction is discharged, at least in part into the atmosphere while the rich gas fraction is fed into an activated carbon delay path whose output is discharged, either directly or indirectly into the atmosphere. Apparatus for carrying out the method is also disclosed.
