Technetium separation |
| abstract |
Method for removing technetium from nuclear waste liquor in a process in which radioactive species are removed by precipitating a ferric floc and then washing the floc prior to cementation thereof, characterised in that there is added to the liquor a source of tetraphenylphosphonium ions to cause dissolved technetium to precipitate before the floc is washed and in that the floc is washed at a low temperature. The method can be used in the Purex process for reprocessing nuclear fuel. |
