Abstract

The hot tests of the trialkyl phosphine oxide (TRPO) process for the removal of transuranium (TRU) elements from high level liquid waste (HLLW), had been carried out with genuine HLLW by means of miniature centrifugal contactors. TRU elements as well as technetium-99 were almost completely extracted by 30% TRPO and very high decontamination factors were obtained. The extracted TRU elements were stripped out and divided into 3 fractions: americium and curium, neptunium and plutonium, and uranium. The cross-contamination of TRU elements between these fractions was very low. The hot tests prove that the TRPO process is an effective and promising process for removing TRU elements as well as technetium-99 from HLLW.
